MTH/219T: Introduction To College Algebra Wk 3 Discussion – Polynomials [due Thurs] Wk 3 Discussion – Polynomials [due Thurs] Wk 3 – Reading and Assignment [due Mon] Discussion Topic Post a total of 3 substantive responses over 2 separate days for full participation. This includes your initial post and 2 replies to classmates or your faculty member.  Due Thursday  This week you will learn about mathematical induction, polynomials, and the parts that make up polynomials. Polynomials are useful because they can be written to represent real-world situations and to solve actual problems. Respond to the following prompts in a minimum of 175 words: What is the situation in your life or future career that would require the use of polynomials? How can you or did you apply polynomials to solve your problem? Provide an example in your response.   Due Monday  Post 2 replies to classmates or your faculty member. Be constructive and professional.     Copyright 2020 by University of Phoenix. All rights reserved.

Question 2 consists of parts a, b, and c – a. Argo sells maintenance services to various private jet operators. Forthese, it demands payment within 20 days. Argo is considering changing this policy to 0.5%/4, net 20. What is the implicit effective annual rate in this payment policy? Use a notional purchase of $1,000.b. Argo’s maintenance service business grosses some $8M per year before discounts and its average days receivable is 25 (unlike the overall business where this number is ~15). If 45% of Argo’s clients opt to pay earlier and get the 0.5% discount, what will be the change in the service business’s receivables? If Argo’s cost of capital is 5.5%, what are the projected savings of this change in policy? If Argo’s gross margin is 25%, by how much will gross dollar revenues have to rise to offset the loss from discounts? In percent?c. A new client from out of town is quoted $3,300 for a repair. The service people ask you to approve this. You do a quick check on the client and assess an 5% default risk. What is the NPV of the client? What is the break-even probability? What is the minimum probability of collecting for you to approve the service?

Variance in statisticsIntroductionProvide an opening paragraph or two that motivates the problem by describing why the topic is useful. It could be that the tool itself is immediately useful in some applications or that the tool is used to build towards more complex methods that are useful in some applications. The nice thing about statistics is that somewhere down the line, it is all about the application. You should identify the application of your topic in the first paragraph or two.A final paragraph of the introduction should tell your reader the structure of your tutorial. You should tell them that you will next offer a section that show cases a specific example of the topic, then the general mathematics behind the topic, another specific example, and last a conclusion.Specific ExampleYou should then provide a specific example of the topic you are writing about. You will most likely need to walk the reader through your example in plain and simple language, giving a more intuitive feel for the topic.GeneralThis section will provide the more general mathematics behind the topic. Use the opening specific example to provide grounding to the more abstract mathematical topics.(A Different) Specific ExampleThis section should provide a more in-depth specific example. This next example should help your audience see more deeply into the topic at hand. On the one hand, you can think of this as just a more complex example. On the other hand, maybe your example is not more complex so much as it helps see something not so obvious about the general mathematics.ConclusionTell your audience what you just told them and remind them why this is important.

Subject: Applied Statistical Methdology for business research designUsing your textbook, LIRN-based research, and the Internet, apply the learning outcomes for the week/course and lecture concepts to the following question.? What makes a function of a discrete variable a candidate for a discrete random variable distribution? What about the counterpart of this candidacy in the case of a continuous variable?? Explain the significance of the mean, variance, and standard deviation for a random variable. Does the significance change when passing from the discrete case to the continuous case?? Provide a detailed discussion on the distribution of a discrete random variable, in general terms, and then provide a numerical example of this distribution. What are the mean and the standard deviation in your example? How does this differ in the case where the random variable is continuous? Explain.? How does the probability of union of disjoint events exhibit itself when dealing with a (discrete or continuous) random variable? Provide an example.

Your directors would also like to know how the gross sales affect the market value of food outlet they might open.1) Draw the scatter plot between market value and gross sales. Add the “type of outlet” variable as an indicator to the scatter plot. Interpret the graph.2) Find the regression equation between the market value and gross sales for each type of outlet. Write the equation, interpret coefficients, goodness of fit and the significance of the model (Use the Data Analysis Toolbox in Excel).
