Determining If a Number Is Prime

Determining If a Number Is Prime A prime number is a numeral that is greater than 1 and cannot be divided evenly by any other number except 1 and itself. If a number can be divided evenly by any other number not counting itself and 1, it is not prime and is referred to as a composite number. Factors vs. Multiples When working with prime numbers, students should know the difference between factors and multiples. These two terms are easily confused, but factors are numbers that can be divided evenly into the given number, while multiples are the results of multiplying that number by another. Additionally, prime numbers are whole numbers that must be greater than one, and as a result, zero and one are not considered prime numbers, nor is any number less than zero; the number two is the first prime number, as it can only be divided by itself and the number 1. Using Factorization Using a process called factorization, mathematicians can quickly determine whether a number is prime. To use factorization, you need to know that a factor is any number that can be multiplied by another number to get the same result. For instance, the prime factors of the number 10 are 2 and 5 because these whole numbers can be multiplied by one another to equal 10. However, 1 and 10 are also considered factors of 10 because they can be multiplied by one another to equal 10. This is expressed in the prime factors of 10 as 5 and 2 since both 1 and 10 are not prime numbers. An easy way for students to use factorization to determine if a number is prime is by giving them concrete counting items like beans, buttons, or coins. They can use these to divide objects into ever-smaller groups. For example, they could divide 10 marbles into two groups of five or five groups of two. Using a Calculator After using the concrete method as described in the previous section, students can use calculators and the concept of divisibility to determine whether a number is prime. Have students take a calculator and key in the number to determine whether it is prime. The number should divide into a whole number. For example, take the number 57. Have students divide the number by 2. They will see that the quotient is 27.5, which is not an even number. Now have them divide 57 by 3. They will see that this quotient is a whole number: 19. So, 19 and 3 are factors of 57, which is, then, not a prime number. Other Methods Another way to find if a number is prime is by using a factorization tree, where students determine the common factors  of multiple numbers. For instance, if a student is factoring the number 30, she could begin with 10 x 3 or 15 x 2. In each case, she continues to factor- 10 (2 x 5) and 15 (3 x 5). The end result will yield the same prime factors: 2, 3 and 5 because 5 x 3 x 2 30, as does 2 x 3 x 5. Simple division with pencil and paper can also be a good method for teaching young learners how to determine prime numbers. First, divide the number by two, then by three, four, and five if none of those factors yields a whole number. This method is useful to help someone just starting out to understand what makes a number prime.

Health care provider and faith diversity Essay Example | Topics and Well Written Essays - 1000 words

Health care provider and faith diversity - Essay Example This means that the caregivers are given the liberty on how to deal with the patient as long as the procedure is aimed at treating the patient. Medicine and prayer should form part of the treatment package for Baha’i followers. Christians believe that in as much as caregivers offer vital services, it is God who heals the sick. Christianity favors medicine and medical practice, faith and prayer during patient care. The paper will discuss the various beliefs in relation to healthcare from various spiritual perspectives. The practice of healthcare at all levels allows nurses to meet and attend to patients from various religious backgrounds and some of them could be holding to beliefs that are different from those held by the nurse. The development of good rapport with the patients is critical for nurses as it allows them to secure maximum cooperation with them. This therefore requires that a nurse should be able to accept diversity of faith expressions among their patients. In this paper, I make analyses of the philosophy/spiritual perspective of care in three faiths namely Buddhism, Sikhism and Baha’i and compare them with the Christian perspective and my personal perspective. The Buddhist approach to healing and health is in regard to its emphasis on spiritual practice, and patient care for Buddhist patients follows the same philosophy. Meditation, belief and spiritual practice are three critical healing components in Buddhism. One of the beliefs is that spiritual practice enables the individual to realize the opportunity for practice in times of adversity like sickness and how to use this opportunity to attain personal transformation and transcendence. This practice replaces the feelings of being a victim with feelings of being a victor. Buddhists also belief that a sick person cannot change their past but can control the future by acting with clarity and skill (Bhikshu, 2006). This requires

Energy Risk Management Dissertation Example | Topics and Well Written Essays - 1500 words

Energy Risk Management - Dissertation Example Regulatory agencies of governments sell smaller units of this limit to individual organisations in the form of emission permit or carbon credit (Bayon, 2007). The emission permit gives an organisation the right to emit a specified volume of green house gas. The carbon credits can be traded in the market and on specified stock exchanges. Organisations must buy the required number of permits equivalent to the amount of emissions. There is a limit on the total number of permits that are offered by the government. If an organisation needs more permits, it can buy these from the market and thus offset their emissions. The whole system of carbon credit trading is rigidly controlled by the stock exchanges. While erring firms now have the option of getting away with pollution and excess emissions, the government is at least making these firms to pay for the emissions. Since the number of carbon credits available is limited, the price of the credits can fluctuate. Eventually, erring firms wou ld be expected to improve their process so that fewer emissions take place. The carbon credit trading market is worth more than 64 billion USD in 2007 and the market is expected to grow rapidly as accountability increases (Tietenberg, 2009). This dissertation will research the structure of carbon credit market and emissions trading. The dissertation will also examine price fluctuations, drivers for price variations and make recommendations to improve the market structure. 1.1. Rationale for the paper The term carbon credit is used to identify a permit or tradable certificate. It gives the owner the permission to emit one tonne of greenhouse gases or carbon dioxide or any other equivalent gas such as sulphur or carbon monoxide. One carbon credit represents one metric tonne of green house gases and is designated by the term tCO2e. The Kyoto Protocol brought in some accountability for nations and signatories to this protocol agreed for some legal targets that limited the amount of emis sions by each nation (Stone, 20110. The European Union Emissions Trading Scheme - EUETS and other bodies have agreed to reduce the CO2 emission by 8% in 2012 as compared to the 1990 levels. As per the protocol and agreements, emission quotas were assigned to each nation and these are called as assigned amount units AAAs. Each nation was allowed to sell these units to industries and even individuals. Based on the nature of industry and processes, each industry was expected to buy a certain amount of units. Failure to comply would result in social stigma besides having to pay extra taxes. In some nations, these units were in shortage and in France, Germany and UK; the price for a unit quickly rose from 50 Euros to 90 Euros per unit. Croci (2011) says that nations such as Russia, Ukraine and many other former USSR satellite nations had huge surpluses and they dumped their AAAs in the market, bringing the market down. It was also seen that during recession, the amount of emissions in ma ny nations reduced and this was mainly due to fewer industries operations. Overall, the market for carbon credit sees a lot of volatility, fluctuations and even price manipulation (Stone, 2010). Existing literature does not examine these aspects or understand the correlation between various drivers. In addition, since the subject of emissions trading is relatively recent, many studies have not been conducted in

Comparing Brave New World to Modern Day

Comparing Brave New World to Modern Day Prediction to future technological warfare in Brave New World When thinking about the greater good and scientific advancement, most people believe that they are always beneficial to society but brave new world gives us the negative perspective of technology advancements. In the novel, brave new world written by Aldous Huxley, warns it readers about technological disadvantages and harms. Particular these disadvantages are evident in the field of biology and technology. Firstly, scientific advancement of which Aldous Huxley warns us is about biological technology used. The huge production of humans is achieved and made through process of bokanovsky process. The Director said , But a bokanovskified egg will bud, will proliferate, and will divide [à ¢Ã¢â€š ¬Ã‚ ¦] every embryo into a full-sized adult (Huxley pg.3-4). Humans are being genetically modified and engineered in the experimental laboratories rather naturally. In the real world scenario, it is seen that cloning is a huge scientific advancement that has been made and is still being developed but is considered unethical when living things are brought into the matter of especially human cloning. This idea is also evident the book of thousand splendid suns where the Taliban controls , brain washes and teach lies , deny other religions , restrict from having freedom of thought from the people of Afghanistan also where weapons are a form of power such as guns and drones. Moreover, connecting to pre sent world we can see that embryonic stem cell research is a real thing where an egg cell is fertilized by a sperm to create a human embryo or basically create life. Keeping in mind this process can be seen unethical by some people as they have different values and beliefs. Just like the bokanovsky process this process is also is messing with an embryo and altering gods work. In Brave new World person intelligence is dependent on the amount of alcohol injected into their individual embryos before the process of life starts. Mr. Foster says that, We can make a new one with the greatest ease-as many as we like (Huxley pg.128). Epsilons have a heavy amount of alcohol injected in the decanting process whereas alphas and betas do not go through that process because Epsilons being a lower class society. Todays science is capable of modifying a person DNA but is not able to fully develop a human being by its own yet cloning of animals has been done in our world. For example, Dolly the shee p is a cloned animal who lived a normal live which offered hoped to scientists to use cloned cells in medicine also it was seen that cloned animals age quicker than normal offspring. But this first cloning done my humanity was a big step towards the future and biological advancement. By making a world where human beings are massively produced biologically, Brave new World illustrated those advancements in the aspects of biology, which display it being dangerous despite the wellbeing and betterment of the human race. According to Huxley, advancements in technology can also be a threat to mankind and the society. Among technological advances, one danger is the growth of pharmacology or the in taking of drugs by people and its side effects. The director says that, One cubic centimetre cures ten gloomy sentiments (Huxley pg.46). Soma helps the users into a dream world, providing them with total relief from fear and providing them with happiness. This relates to the character Abigail William, from the crucible where she is acting as soma to the society. Abby manipulates people to get what she wants; her intentions are solely to benefit herself. She does not care about the consequences of her actions as well as she is able to manipulate the town to hurt the people she does not like. Just like the soma which is acting as positive thing for the people of brave new world but in reality a negative one, we can see how medical advancements such as x-ray devices, MRI machines and medical drugs help a person restore his/ her health and making the average human life expectancy much better as years are passing. Technology effects entertainment by altering all the games to be played by humans. Mustafa Mond says that, All conditioning aims at making people like their inescapable social destiny(Huxley pg. 13). Game make less organization, making a person bound to a superficial entertainment as it defies the ideology to be creative. This relates to a thousand splendid suns because men in the book do not care what happens to a women, so do the people of brave new world not care about connecting on an emotional level with each other, everybody serves their purpose within society and each person is there for anybody to use (even sexually) which is similar to a thousand splendid suns where the wife only role is to serve their husbands purpose and fulfill their needs just like Laila providing Rasheed with an heir. This can also relate to our present teenagers gaming mindset where advancement in ga ming technology have caused massive violence and hatred among teens making them do crime. For example Grand theft Auto is a game about stealing, shooting and hurting random people. Due to his game one of the incident that occurred in United States was the one teenager who shot two police men and was prisoned due to his crime. Similar to biological disadvantages, technology can be a dangerous factor towards the society if used inappropriately and without the regarded for the well-being of the human race. Society must ensure that technology and scientific advancements is changing to suit human needs but rather changing human race to suit science. Moreover the world one day without individual free will and sense would make it impossible to overcome these factors. Works Cited Huxley, Aldous, Margaret Atwood, and David Bradshaw. Brave New World.

College Entrepreneurs Do Good and Make Money

â€Å"College Entrepreneurs Do Good and Make Money,† (Nickels, McHugh, & McHugh, 2010, p. 26). They are really business and success story. True college entrepreneurs will do anything possible to reach their goals by being original and innovative. They pick an idea based on the customer needs and use it to develop the plan. We have heard about several young millionaires entrepreneurs that started their business while they were still attending college, such as Mark Zuckerberg who launched Facebook while still attending Harvard. Now he is one of the youngest billionaires in the world. Ryan Allis and Aaron Houghton were also college students with the determination of success, and they have taken their dreams into a blossoming entrepreneur. We find their case as a really good lesson to learn about being a successful entrepreneur, these two young college students were able to take risk and find a need to fill in the community. Another thing that was imperative for their success was the preparation of their idea about the role of each other into the business. They were able to take something they both enjoyed; computers, and create a business using their mutual talents. Aaron had strong product development skills, and Ryan was bright in marketing skills; they complemented each other very well, this helped with the growing of the corporation. Once you have your business scheme you must make certain that you have a well-defined plan. It must offer a clear direction for the enterprise and describe the market you wish to target, also the potential risks and rewards, the people that will help you get there, and how you are going to get there. We think that having a dream is great but it will not move you to start anything; you need to have willpower to be able to execute the first step. Aaron and Ryan only had a couple of hundred dollars to start their business, but they were able to run their business and start with a small amount of capital. They basically started with the little resources they already had; the internet, technology, and a love to access to computers. We do not need to start gigantic to create a successful business. We also think that the fact that Ryan and Aaron were young and seem that they did not have a family to support, pay mortgages or children to rise. They were not depending on a profit from their initial investment, in contrast, with a person with a family and responsibilities to face. Determining the accurate level of planning to do can be not easy. But we agree, that waiting too long will not get you going, it is important to start and you will find new resources, meet new people, and get new opportunities to make your dream come true.

Social Observation Paper

I decided for my social observation the mall would be a good place to start. I came there on a Friday evening when there should be plenty of people to watch. I also sat in the Barnes and Noble cafe after that to observe. I expected to see a lot of people shopping and conversing. A few things did stand out to me within the few hours I was there. Some things I didn’t expect to see. We are expected to behave a certain way in public determined by our culture as to what is acceptable. Some people stay well within the lines while some might stray outside the norms but never too far typically.Usually the ones to travel to the extremes are adolescents and teenagers. This is what I observed. As I sat in the chair near the entrance to Bergner’s I noticed a couple groups1 of kids, they looked like they were probably in 8th grade or near there. One group totaled six kids and you could tell who the leaders with high status2 were in the group. They displayed achieved status3 and walk ed in the middle typically with couple others following behind trying to keep up and stay in the conversation.I call it achieved status because they had more confidence and walked taller than the others, of course they could be from a rich family but from visual evidence achieved status seems to be the case here. The group seemed playful and was very pushy towards one another. While the leaders looked like they came out on top and were more dominant keeping the others in line, and sometimes ignoring the other members of the group, showing they weren’t impressed by them. Another Group was smaller with only three kids in it.These kids seemed like they had less energy and were more of wandering at a leisurely pace compared to the other group which was moving swiftly. Both groups walked by about three times, apparently they had nothing better to do with their time and weren’t shopping. I’m assuming they were probably dropped off by their parents to hang out at the m all with their friends and maybe get some food at the food court. Another idea is that their parents could be busy shopping and they are just wandering while their parents are busy, I think this is less probable.The larger group was Dominated by all males, which is another thing I didn’t expect. You would think that the group would have at least one or two females in it, statistically speaking. The smaller group was female dominated with two females and a single male in it. I observed the male and he didn’t seem to follow his gender role4. This made me think because I have a gay friend and homosexual men seem to familiarize with females more easily than heterosexual males.Also I noticed a trend that most gay men spent most of their time being raised by their mother with a more distant or even non-existent father figure. It is probably not fair to make assumptions about the lone male in the group, but I’m assuming he fits in this stereotype5. The other thing I no ticed about this group is that they all seemed to be equal; there wasn’t one that put themselves before the others. I also sat in the cafe at Barnes and Noble for a while and observed socialization and interactions. The first people I noticed when I was sitting were a couple walking through the store.The Female had her man by the hand, I noticed her hand was palm down, signifying authority, and was leading him off somewhere, maybe she was in a hurry to get somewhere or had just caught him eying another female. Either way she seemed to be the more dominant one in the relationship, which does not correspond with gender roles or the typical culture6 of ours. The next thing I noticed were the people sitting in the cafe. There were pairs of people everywhere, there were people sitting by themselves reading but there were a lot of groups of two, but never a group more than two.This to me was interesting and I asked why this might be. I came to the conclusion that the coffee shop is a more intimate setting to socialize one on one, also the space was smaller so that could have contributed to the fact too. I noticed an elderly couple, they seemed to comfortable and familiar with each other that they didn’t need to even communicate verbally they could sort of sense what the other wanted and then asked a question. For example I noticed the man shifted his body and glanced toward snack sign, luckily I was within earshot to hear the conversations of the people around me.She knew right away the old man was hungry and asked him if he wanted a cheesecake, Apparently this was one of his favorites cause he said â€Å"heck yeah! †. The couple did not display value7 over one another, but rather value for each other. This was my day out evaluating the interactions and socialization of our local people here in Rockford. I am curious to see what kind of interactions I would see at a market in indo-china and how different that would be to our culture here. It mig ht be so different that I couldn’t understand it.I learned a lot by watching the people and found a few interesting things. Like how groups of teenagers with time can be so full of confidence and have what seems like all the time in the world on their hands. Also on the other side of the spectrum are the seniors I observed that seemed to be content and also have all the time in the world. While it seems for me there are not enough hours in a day to get everything I need done. 1. Groups: a number of people or things that are classed together 2.Status: The economic or social level of an individual 3. Achieved Status: The level of status gained through effort or work 4. Gender Role: The social expectations of a male or female individual 5. Stereotype: an unreliable generalization about all members of a group 6. Culture: the totality of learned socially transmitted customs, knowledge, material objects, and behavior. 7. Value: a collective conception of what is considered good, de sirable, and proper-or bad, undesirable, and improper in a culture.
