Create a program/function using PYTHON that takes cents and returns to the customer how MANY coins it takes to make the change...

Ex. if the change owed is 50 cents then return a 2 (for two quarters)

if the change owed is 10 cents then return a 1 (for one dime)

AGAIN please write this in java and please provide EXPLANATION of answer

Two methods of maintenance for indefinite service life are being evaluated:

Method 1. The first cost would be $60,000, and $25,000 would be required at five-year intervals forever.

Method 2. The first cost would be $150,000, and $180,000 would be required at 50-year intervals of forever.

At I i = 12%, which method is the better one?

One year​ ago, your company purchased a machine used in manufacturing for $ 90 comma 000. You have learned that a new machine is available that offers many advantages and that you can purchase it for $ 170 comma 000 today. The CCA rate applicable to both machines is 40 %​; neither machine will have any​ long-term salvage value. You expect that the new machine will produce earnings before​ interest, taxes,​ depreciation, and amortization​ (EBITDA) of $ 45 comma 000 per year for the next 10 years. The current machine is expected to produce EBITDA of $ 22 comma 000 per year. All other expenses of the two machines are identical. The market value today of the current machine is $ 50 comma 000. Your​ company's tax rate is 42 %​, and the opportunity cost of capital for this type of equipment is 11 %. Should your company replace its​ year-old machine?

Question 1 (25 marks/ Time Value of Money and WACC)

(a) You need to pay off a car loan within the next two years. The payment will be $4,000 every month. Today you have made a single deposit into a return-guaranteed investment account that will allow you to cope with all the monthly payments. This account earns an effective annual interest rate of 12.68250301%. The first payment will be made in one month.

1. (i) Calculate the corresponding monthly rate for the investment account.

2. (ii) “You need to have at least $96,000 at your account today in order to make all the payments on the car loan in the next two years.” True or false? Briefly explain without doing any time value of money related (i.e. PVA or FVA) calculations.

3. (iii) What is the amount of the single deposit made today?

4. (iv) If your mother is going to make the first year’s repayments for you (as a birthday gift) and thus you don’t need to withdraw the $4,000 every month from the investment account, how much more money will you have in your bank account two years from

now?

1. Find the appropriate measure of center. Discuss why the chosen measure is most appropriate. Why did you decide against other possible measures of center? 2. Find the appropriate measure of variation. The measure of variation chosen here should match the measure of center chosen in Part 1. 3. Find the graph(s) needed to appropriately describe the data. These may be done by hand and inserted into the Word document. You can also use Excel or a Web Applet to create a Histogram of the chosen data. Graphs can be copied and pasting onto the template. 4. Define the random variable (X) so that your chosen data set represents values of X. 5. Is your chosen random variable discrete or continuous? Explain how you know. 6. Would the Normal or Binomial distribution be a good fit for the underlying sample distribution of X? If one of them is a good fit, state how you would approximate the distribution parameters (Use the mean and standard deviation of the data chosen) 7. If you selected column D, calculate the probability that a flight will depart early or on-time. If you selected column E, calculate the probability that a flight will arrive early or on time using the empirical definition of probability. 8. If you selected column D, calculate the probability that a flight will depart late. If you selected column E, calculate the probability that a flight will arrive late using the empirical definition of probability. 9. For those that selected column D, assume now that the random variable X = Departure Time is exactly normally distributed with mean m= -2.5 and standard deviation s= 23. Compute the probability of a flight arriving late based on this new information. For those that selected column E, assume now that the random variable X = Arrival Time is exactly normally distributed with mean m= -2.5 and standard deviation s= 23.
