As the first days of work on the Dune Buggy progress, you are concerned that information provided to you from your seconded supervisors, in terms of work completed, may not be accurate. As a result you may be experiencing problems which will only surface much later, when it will be to late for corrective action.

To remedy the problem, you decide to implement the same system of rigid controls that A-1 is being forced to apply on its military contracts, ie. Earned Value.

As a first step, using the following pricing data developed for the Cement Dune Buggy Project augmented with overhead costs, determine a cost/schedule baseline, by calculating the Planned Value (PV) for each of days 10, 25 and 40 .

Assume that all activity costs are distributed evenly on a daily basis.

Your firm, Agrico Products, is considering a tractor that would have a cost of $37,000, would increase pretax operating cash flows before taking account of depreciation by $12,000 per year, and would be depreciated on a straight-line basis to zero over 5 years at the rate of $7,400 per year beginning the first year. (Thus, annual cash flows would be $12,000 before taxes plus the tax savings that result from $7,400 of depreciation.) The managers disagree about whether the tractor would last 5 years. The controller insists that she knows of tractors that have lasted only 4 years. The treasurer agrees with the controller, but he argues that most tractors do give 5 years of service. The service manager then states that some last for as long as 8 years.

Assume that if the tractor only lasts 4 years, then the firm would receive a tax credit in Year 4 because the tractor's salvage value at that time is less than its book value. Under this scenario, the firm would not take depreciation expense in Year 5.

Given this discussion, the CFO asks you to prepare a scenario analysis to determine the importance of the tractor's life on the NPV. Use a 40% marginal federal-plus-state tax rate, a zero salvage value, and a 10% WACC. Assuming each of the indicated lives has the same probability of occurring (probability = 1/3), what is the tractor's expected NPV?

Round your answers to two decimal places. Do not round intermediate calculations. Negative amount should be indicated by a minus sign.

Your firm, Agrico Products, is considering a tractor that would have a cost of $35,000, would increase pretax operating cash flows before taking account of depreciation by $13,000 per year, and would be depreciated on a straight-line basis to zero over 5 years at the rate of $7,000 per year beginning the first year.

Task 2: Debugging and writing functions

1. In IDLE, use the File -> New Window menu option to open a new editor window for your program, and save it using the name hw4Task2.py. Make sure to specify the .py extension.
2. Copy the following (buggy) code into that file:

def mysum(x, y)

""" takes two numbers and returns their sum """

    total = x + y

    print(total)

3. Save the file using Ctrl-S. Then try to run it using F5. What happens?
4. This function includes two syntax errors – errors that violate the rules of the Python language. See if you can find and fix them, continuing until you are able to run the file without any error messages. (Create a MS Word file and name it Task2 steps”. Use this word file, to write what you did to fix the errors in this step.)
5. Once you have eliminated the syntax errors, test the function from the Shell as follows:

>>> mysum(44, 67)

>>> print(mysum(10, 7))

What happens? Why?

(Use the MS Word file “Task2 steps”, and write your answer to this step.)

6. Fix the function so that both above tests work as expected.  (Use the MS Word file “Task2 steps” and write what you did in this step.)
7. In hw4Task2.py, write a function named sum_double that accepts two integers as parameters. The function should return the sum of the integers, unless the two values are the same, in which case the function should return double their sum. For example:

                 >>> sum_double(1, 2)

                 3

                 >>> sum_double(3, 2)

                 5

                 >>> sum_double(2, 2)

                 8

Be sure to write a docstring for the function.

After writing the function, test it in two ways:

• Make function calls from the Shell like the ones shown above.
• Copy the following code into your file:

def test():

    """ function for testing """

    test1 = sum_double(1, 2)

    print('first test returns', test1)

    # Add more tests below

This code provides the beginnings of a test function, with lines that call the function with a set of inputs and print the return value. It’s worth noting that this function does not need a return statement, because its sole purpose is to make test calls and print their results.

You should:

• add other test cases to the test function
• run the Python file
• call the test function from the Shell (by entering the call test()) and check that you obtain the correct return values for each test case.

(Use the MS Word file “Task2 steps”and write what you did in this step.)

A consonsultant wishes to invest up to a total of $25000 in two types of securities, one that yields 10% per year and another than yields 8% per year. They believe that the amount invested in the first security should be at most one third of the amount invested in the second security. What investment program should the consultant pursue in order to maximize income? (Use constraint inqualities with objective function)

I need a regression analysis done on the following numbers.

A.) Find the regression​ equation, letting the first variable be the predictor​ (x) variable. Using the listed​ actress/actor ages in various​years, find the best predicted age of the Best Actor winner given that the age of the Best Actress winner that year is 34 years. Is the result within 5 years of the actual Best Actor​ winner, whose age was 52 years?

find the equation of the regression line.

Graph the regression line on the scatterplot. In this​ case, the regression line does not fit very well because the data do not appear to be linear.

Use the regression equation for predictions only if the linear correlation coefficient r indicates that there is a linear correlation between the two variables. Use technology to calculate the linear correlation​ coefficient, rounding to three decimal places. what is r=
