R.A.T.-Create Your Own Water Park Apply your knowledge of polynomial functions to create a water park, with 6 waterslides - one for under 6 years old (highest point at least 5m above ground) two for ages 6 to 12 (highest point at least 10m above ground) three for over age 12 (highest point at least 20 m above ground)

A Create a polynomial equation for each waterslide. Show all of your work. The waterslide must begin at the y axis and the x axis must represent the ground. For each function, write the original function in factored form, then explain the transformations that were performed, in order to obtain the model function.

B. Graph (and print) each function using desmos. State the domain and range of each function.

C. Choose one of your waterslides and determine the interval(s) in which the height of the ride was above 3m. Explain your method.

D. Choose one of the waterslides for ages 12 and up and state the interval (from peak to trough) where the waterslide is steepest. Then determine the average rate of change for that interval (by using the equation). Next, determine the instantaneous rate of change at the point in the interval when the person is moving the quickest. Interpret the meaning of these numbers. Note: the maximum steepness of a ride should not exceed 4:1, rise to run. The waterslide should be decelerating as it comes to a stop.

Alden Construction is bidding against Forbes Construction for a project. Alden believes that Forbes’s bid is a random variable B with the following mass function: P(B $6,000) .40, P(B $8,000) .30, P(B $11,000) .30. It will cost Alden $6,000 to complete the project. Use each of the decision criteria of this section to determine Alden’s bid. Assume that in case of a tie, Alden wins the bidding. (Hint: Let p Alden’s bid. For p 6,000, 6,000 p 8,000, 8,000 p 11,000, and p 11,000, determine Alden’s profit in terms of Alden’s bid and Forbes’s bid.)

Second Chance Inc. purchased a lot with an old warehouse on the premises for $420,000 on

January 1, 2016. The company immediately demolished the building and cleared the site at a

cost of $150,000. Castle then commenced construction of a new warehouse for their own use on

March 1, 2016. The warehouse took 14 months to construct and was ready to be used on April

30, 2017. Expenditures for the construction were as follows:

March 1, 2016 deposit $400,000

May 30, 2016 $600,000

December 31, 2016 $800,000

February 1, 2017 $300,000

April 1, 2017 $400,000

The Company uses the specific interest method of computing capitalized interest and had the

following indebtedness during the period of construction:

Loan #1 borrowed $3,000,000 March 31, 2014 at a rate of 6%, due September 30, 2017

Loan #2 borrowed $2,000,000 January 31, 2016 to build the warehouse at a rate of 7%, due

January 31, 2026

When the warehouse is placed in service, it will be depreciated on a straight line basis over 30

years with zero assumed salvage value.

The state of California has a mean annual rainfall of 22 inches, whereas the state of New York has a mean annual rainfall of 42 inches. Assume that the standard deviation for both states is 4 inches. A sample of 34 years of rainfall for California and a sample of 46 years of rainfall for New York has been taken.

(a)

Show the probability distribution of the sample mean annual rainfall for California.

A bell-shaped curve is above a horizontal axis labeled inches.

• The horizontal axis ranges from about −2.1 to about 2.1.
• The curve enters the viewing window near −2.1 just above the horizontal axis, curves up to the right, and reaches a maximum near 0.
• The curve then curves down and to the right until it leaves the viewing window at the same height it entered near 2.1.

A bell-shaped curve is above a horizontal axis labeled inches.

• The horizontal axis ranges from about 39.9 to about 44.1.
• The curve enters the viewing window near 39.9 just above the horizontal axis, curves up to the right, and reaches a maximum near 42.
• The curve then curves down and to the right until it leaves the viewing window at the same height it entered near 44.1.

A bell-shaped curve is above a horizontal axis labeled inches.

• The horizontal axis ranges from about 19.9 to about 24.1.
• The curve enters the viewing window near 19.9 just above the horizontal axis, curves up to the right, and reaches a maximum near 22.
• The curve then curves down and to the right until it leaves the viewing window at the same height it entered near 24.1.

(d)

In which case, part (b) or part (c), is the probability of obtaining a sample mean within 1 inch of the population mean greater? Why?

part (c), because the population standard deviation is smallerpart (c), because the sample size is larger    part (b), because the standard error is smallerpart (b), because the population standard deviation is smaller

Concur Technologies, Inc., is a large expense-management company located in Redmond, Washington. The Wall Street Journal asked Concur to examine the data from 8.3 million expense reports to provide insights regarding business travel expenses. Their analysis of the data showed that New York was the most expensive city, with an average daily hotel room rate of $198 and an average amount spent on entertainment, including group meals and tickets for shows, sports, and other events, of $172. In comparison, the U.S. averages for these two categories were $89 for the room rate and $99 for entertainment. The table in the Excel Online file below shows the average daily hotel room rate and the amount spent on entertainment for a random sample of 9 of the 25 most visited U.S. cities (The Wall Street Journal, August 18, 2011). Construct a spreadsheet to answer the following questions.

1. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables?

   The scatter diagram indicates a _________ linear relationship between the hotel room rate and the amount spent on entertainment.

2. Develop the least squares estimated regression equation.

   Entertainment=______+_________ room rate (to 4 decimals)

3. Provide an interpretation for the slope of the estimated regression equation (to 3 decimals).

   The slope of the estimated regression line is approximately . So, for every dollar _________ in the hotel room rate the amount spent on entertainment increases by $.

4. The average room rate in Chicago is $128, considerably higher than the U.S. average. Predict the entertainment expense per day for Chicago (to whole number).
