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?

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?

Suppose that the chance of rain tomorrow depends on previous weather conditions only through whether or not it is raining today and not on past weather conditions. Suppose also that if it rains today, then it will rain tomorrow with probability 0.6, and if it does not rain today, then it will rain tomorrow with probability 0.3, then

a. Calculate the probability that it will rain four days from today given that it is raining today.

b. What is the limiting probability of rain.
