Cedar Point amusement park management is preparing the park's annual promotional plan for the coming season. Several advertising alternatives exist: newspaper, television, radio, and displays at recreational shows. The information below shows the characteristics associated with each of the advertising alternatives, as well as the maximum number of placements available in each medium. Given an advertising budget of $125,000, how many placements should be made in each medium to maximize total audience exposure? Formulate this as a linear programming problem to be solved using QM.

A theme park owner records the number of times the same kids from two separate age groups ride the newest attraction.

Using the computational formula, what is the SS, sample variance, and standard deviation for the age group of 13–16? (Round your answers for variance and standard deviation to two decimal places.)

SS sample variance standard deviation

You decide you want to build a skate park in your backyard, so you need to buy a lot of concrete. The good news is, you can get a discount when you buy in bulk. The price of concrete for different grades of concrete per cubic yard is as follows:

• when grade is either "low" or "cheap"
  • $100 (per cubic yard) for less than 200 cubic yards
  • $95 for between 200 and 400 (including 200 and 400) cubic yards
  • $90 for more than 400 cubic yards
• when grade is either "high" or "expensive"
  • $150 for less than 250 cubic yards
  • $135 for 250 or more cubic yards

Write a program that calculates the price of an order of concrete when given the grade and quantity.

Notes

• You can assume valid input.
• The grader is checking if your output ends with the integer dollar amount (no cents or punctuation).

Examples

What grade of concrete (low/cheap, high/expensive)?
low
How many cubic yards of concrete?
75
The cost is $7500

The answer to the example above is calculated from 75 * $100 (low grade, less than 200 cubic yards) = $7500

What grade of concrete (low/cheap, high/expensive)?
cheap
How many cubic yards of concrete?
75
The cost is $7500

What grade of concrete (low/cheap, high/expensive)?
high
How many cubic yards of concrete?
75
The cost is $11250

What grade of concrete (low/cheap, high/expensive)?
expensive
How many cubic yards of concrete?
75
The cost is $11250

6.   Jiffy Park Corp. has annual sales of $50,705,000, an average inventory level of $15,015,000, and average accounts receivable of $10,015,000. The firm's cost of goods sold is 85% of sales. The company makes all purchases on credit and has always paid on the 30th day. However, it now plans to take full advantage of trade credit and to pay its suppliers on the 40th day. The CFO also believes that sales can be maintained at the existing level but inventory can be lowered by $1,950,000 and accounts receivable by $1,950,000.

      a.   What is Jiffy Park’s cash conversion cycle (CCC) prior to the changes proposed?

      b.   What is Jiffy Park’s CCC after implementing the suggested changes?

      c.   What is the net change in Jiffy Park’s CCC given what you just calculated above?

theme park owner wants to know if the children’s rides are favoring 10 year old girls over 10 year old boys based on height. In other words, does one group taller than the other and thus can go on more rides?

Part a: The owner gathered height data on 10 year old girls and 10 year old boys, see data below. Determine at the 5% significance level if there is evidence that the two genders are not the same height and thus cannot all go on the same rides. Show your work and give your answer in complete sentences in context of the problem.

Part b: After doing some research, the owner found the following information about the expected height and standard deviation for 10 year olds. Does that change the result of part a? Show your work and give your answer in complete sentences in context of the problem.

Parking charge application: A parking garage charges a $20.00 minimum fee to park for up to 3 hours. The garage charges an additional $5.00 per hour for hour or part thereof in excess of 3 hours. The maximum charge for any given 24-hour period is $50.00. Assume that no car parks for longer than 24 hours at a time. Write a program that calculates and prints the parking charge for each of 3 customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should save the result in a array of Customer. The class customer is the following:

class customer{ string plate; float hour; float fee; }

Your program should use the function calculateCharges to determine the fee for each customer. You should print the result for the 3 customers in the following format:

Plate Hours Charge

132AAC 1.5 20.00

236URT 4.0 25.00

390ROP 24.0 50.00

TOTAL 29.5 95.00

In doing this question make sure to keep the array of customer as global variable.

The stock of Arbor Pet Trees (APT) is priced based on the given systematic risk factors. Estimated sensitivities to these risk factors are given by the betas of the regression RAPT – Rrf = βcreditRcredit + βvalue Rvalue + α + ε Factor Risk Premium Beta Credit Risk 5.6% 1 Valuation Risk 3.8% 0.3 Risk-free rate 2.1% If the actual return is 9.2%, what is the value of alpha?

Suppose that U.S. consumption spending is ​$13.5 ​trillion, gross private domestic investment is ​$2.3 ​trillion, government spending is ​$3.3 ​trillion, and net exports are −$0.3 trillion. If interest income is ​$1.2 ​trillion, depreciation is ​$0.6 ​trillion, wages are ​$12.6 trillion, and rental income is ​$0.7 ​trillion, what is the net​ investment?

The net investment is? ​(Enter your response rounded to one decimal​ place.)

15. A reversed Carnot engine (refrigeration unit) is used to maintain the temperature inside a freezer at -34 ^oC. The room temperature in which the refrigeration unit operates is a constant 24 ^oC. If the motor on the refrigeration unit uses 0.3 kW, determine the rate at which heat is removed from the freezer in Watts.

State your answer in whole numbers. Example: 2147

Suppose the risk-free rate is 3.5%; on average, an AAA-rated corporate bond carries a credit spread of 0.3%, an A-rated corporate bond carries a credit spread of 1.1%, and a B-rated corporate bond carries a credit spread of 3.9%. Company XYZ’s outstanding debt is rated BBB by rating agencies. What would be the cost of debt for XYZ based on prevailing market rates?
