Linear Programming ProjectOverviewFor this assignment, your instructor will assign a linear programming project based on the following specifications:It will be a problem with at least three constraints and at least two decision variables.The problem will be bounded and feasible. It will also have a single optimum solution (in other words, it won’t have alternate optimal solutions).The problem will also include a component that involves sensitivity analysis and the use of the shadow price.InstructionsYou will be turning in two deliverables, a short writeup of the project, and the spreadsheet showing your work.WriteupYour writeup should introduce your solution to the project by describing the problem.Correctly identify what type of problem this is. For example, you should note if the problem is a maximization or minimization problem, as well as identify the resources that constrain the solution.Identify each variable and explain the criteria involved in setting up the model. This should be encapsulated in one or two succinct paragraphs.After the introductory paragraph, write out the LP model for the problem. Include the objective function and all constraints, including any non-negativity constraints. Then, you should present the optimal solution, based on your work in Excel. Explain what the results mean.Finally, write a paragraph addressing the part of the problem pertaining to sensitivity analysis and shadow price.SpreadsheetPlease set up your problem in QM for Windows or Excel and find the solution using Solver.Clearly label the cells in your spreadsheet.You will turn in the entire spreadsheet, showing the setup of the model, and the results.This course requires the use of Strayer Writing Standards.

I need 5 responses tonight

/in /by

Need 5 response no words count.First post:My thoughts is that everything we have has always been there, but it just takes someone to discover it. Everything is waiting to be discovered, including math. Math can keep expanding just like everything else such as science and history. Perhaps it is called invention because one is the first to discover it. All our tools are in our head, one must just open up. Perhaps some rules were created for us, such as hours in a day, etc. I am not exactly on one side here, but I do think it has always been there, even if it is modified a bit.Second post:This question is hard to answer because the definition of invent and discover have very similar meanings.  The definition of invent is “to create or design (something that has not existed before); be the originator of.”  The definition of discover is to “find (something or someone) unexpectedly or in the course of a search.”  If something is invented that means somebody discovered it and then made it into an invention.  You can’t invent something without discovering it and you once you discover something, it becomes invented.With mathematics, it seems like the symbols, equations, and rules are already there, just waiting to be discovered.  It has to do with a bunch of rules that you apply to real life situations.  I think with technology, it is invented.  Once math terms are discovered, people can invent technology around it.  For example, a calculator was invented and whoever invented had to put it together and let it know the equations for it to solve the problem.  There is problem more terminology out there that will eventually be discovered.   Also, there may be things and methods that will eventually be invented because of everything else that has already been invented.  Some things may have been discovered just by the human brain, such as a graph, once the term probabilities was invented, people found out you could draw a graph to indicate the same information.  I think all of this was meant to be discovered and invented because we use these methods for everything especially in cooperate America.  If we didn’t have these methods, charts, equations… etc. we wouldn’t be able to predict future finances.  It’s used in sciences and engineering work; it’s a necessity in life.  Some will ask if it’s already out there just waiting to be discovered, which you could ask that question for anything.  Is technology already out there waiting to be discovered, was the iphone 7 already out there but needed the iphone 6 to be discovered before.  Nobody knows what is out there until it is discovered or invented. (Not just discovered or not just invented)After reading all the opinions, I still can’t just pick one side, so I decided to go with both, mathematics is discovered and invented.Third post:It took me a while to figure out what side to choose whether math was invented or discovered. I could agree with both but I am leaning more on the side of it being invented “unknowingly.” Math isn’t just something we can come across in a field and pick up and “discover it.” A time where I think it could’ve all started is when mankind started to trade goods. In order to keep up with their stuff. But I’m sure it goes way back in time like for instance- time. People had to keep up with time and the year and so forth for the records. As mankind evolutionized so did math amongst other things. It was a creation with room for growth and I believe it’s honestly endless because it can be incorporated in so many things. We are very curious beings and for that people are not going to stop trying to take math further than it already has because somehow we have made it a way of life and incorporated it in so many areas where it’s necessary to be used.Fourth post:Its pretty hard to say whether or not math is “discovered” or “invented”; but I think its a little safer to say that mathematics is discovered rather than invented only because when you think of an invention, you think of someone putting objects together to form an overall outcome of something. Usually when someone invents something it typically consist of the same concepts whereas with mathematics you have many different concepts that all work in different ways for a different outcome. Although I believe it could be discovered I still ask myself, “If its discovered where exactly does it come from? Where did it originate?” Dinosaurs were discovered but we know that they were actually living on earth and became extinct, but where are these mathematical concepts coming from?fifth post :After a little bit of deep thought about Mathematics as a discovery or an invention, I have decided to take a side, if for anything other than the practice or a sound argument.  I’d like to believe that Math was discovered. Since the beginning of time man has needed a way to survive.  Humans needed (and still do currently) food, shelter, water to name a few.  I will use the idea of Applied Mathematics.Humans keeping track of the seasons, moon phases, and creating decorative shapes seem to be the earliest forms of math.  If the moon for example is setting each evening, they could have a way to know by tallying.  Also the Chinese used a number system that was a bit more complex than that of the rest of the world at the time.  They needed a way to measure weights of food for trading. (Storyofmathematics.com)It seems that mainly math was used for monetary purposes even if money had not existed yet.  It could be used to trade a certain quantity of items. The reason why people would need to monitor seasons, would be obvious, for vegetation. It seems like the only and main reason for math, is money.  Needing to monitor moon phases or setting geometric shapes for decorative purposes seems more for enjoyment and or religion. Also the philosophical question of ‘Who Am I, and Why Am I Here’? comes to mind.According to Plato, Math is very real, regardless if we are there to witness it or not.  Math would exist on other planets with no life on them.  Math could explain phenomena in the universe.  Perhaps humans are not to the level to where we can fully understand the most advanced Mathematical concepts. Perhaps we will use our own knowledge to destroy ourselves.

Probability and Statistics

/in /by

1. (5 pts) Meredith Watts, police chief of Shorewood, knows that the probability of any rape that occurs in the city being reported to the police is .5. If a rape is reported, the probability that someone will be arrested is .6. If someone is arrested, the probability of a conviction is .9. If a person is convicted of rape the probability of actually serving jail time is .7. Given that a rape occurs, what is the probability of a person serving jail time for the crime?2. (10 pts) The governor of a large, northeastern state is trying to decide whether to veto a bill that she opposes that has been passed by the state legislature. As a politically minded actor, she has adopted the decision rule that if the bill has a probability greater than .5 of becoming a law even if she vetoes it, then she will sign the bill despite her opposition (and no doubt share credit for its passage). There are two ways in which the bill may become law over her veto. First, the state legislature may overturn her veto by voting resoundingly for passage. The governor estimates the probability of this outcome to be .3. The second way is through a referendum involving the voters of the state. If she vetoes the bill, and the legislature does not pass it over her veto, she further estimates that the probability of a referendum movement occurring is .9 (a powerful interest group supports the bill). She further estimates that the probability that the referendum movement will obtain the required number of signatures to qualify for a vote of the citizens of the state is .75.  Finally, she estimates that given a referendum, the voters have a 50/50 chance (P = .5) of approving the bill. Based on the governor’s decision rule, should she veto the bill?3. (5 pts) The average time a visitor spends at the River Park Art Exhibit is 62 minutes. The standard deviation is 12 minutes. If a visitor is selected random, find the probability that he or she will spend at least 82 minutes at the exhibit.4. (5 pts) A Channel 4 News story claims that the city environmental preservation unit pays too much for routine automobile maintenance of the vehicle fleet. The average (mean) amount paid by the unit is $104.15 with a standard deviation of $9.71 (normal distribution).  As an initial step, the unit head decides to investigate the most expensive 25% of the routine maintenance bills.  According to this criterion, above what dollar amount should bills be investigated?5. (10 pts) A recent study of 25 commuters showed that they spent an average of $18.23 on public transportation per week. The standard deviation of the sample was $3.00. Find the 95% confidence interval of the true population mean. Assume the variable is normally distributed. (10 points)Hypothesis Test (Use the FIVE Steps)6. (10 pts) A maker of frozen meals claims that the average caloric content of its meals is 800, and the standard deviation its meals (population) is 25. A researcher tested 12 meals and found that the average number of calories was 873. Is there enough evidence to reject the claim at a = 0.05? How about a = 0.02?7. (10 pts)  A college professor claims that the average cost of a paperback textbook is greater than $27.50. A sample of 50 books has an average cost of $29.30. The standard deviation of the sample is $5.00. Find the P-value for the test. On the basis of the P-value, should the null hypothesis be rejected at a = 0.05?8. (10 pts) The police department of Youbet, Michigan, is considering the purchase of new radar guns.  On the average, the guns presently used by the department can detect a speeding vehicle at a distance of 2217 feet.  In order to demonstrate the new radar guns, the manufacturer has allowed the Youbet police department to use the guns for a short period of time.  A random sample of 20 days in action shows that the new guns can detect a speeding vehicle at 2230 feet (mean) with a standard deviation of 72 feet. In your opinion, should the department purchase the new radar guns?I need a hundred percent!
