Masters Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $385,000 is estimated to result in $145,000 in annual pretax cost savings. The press falls in the MACRS five-year class, and it will have a salvage value at the end of the project of $45,000. The press also requires an initial investment in spare parts inventory of $20,000, along with an additional $3,100 in inventory for each succeeding year of the project. The shop’s tax rate is 22 percent and its discount rate is 9 percent. Refer to Table 10.7. Calculate the NPV of this project. (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) (NOTE: show CF function inputs to find the NPV) Should the company buy and install the machine press? Yes No

Privacy program, lab2pr2.py Write an automated password-hiding program that
could be used in automatic password manager. The program will first read user
passwords, one at a time, and store them in a list. When the user enters an empty
string (just hits enter), they are finished with the input. The program should
then replace each password with a string of * corresponding to the length of the

original password. As the output, the program should print the original list and
the resulting list.
For instance, here’s the output from a sample run of your program:
Please enter a password (press [enter] to finish): Tulane123
Please enter a password (press [enter] to finish): Bruff
Please enter a password (press [enter] to finish): LBCLBC
Please enter a password (press [enter] to finish):
[’Tulane123’, ’Bruff’, ’LBCLBC’]
[’*********’, ’*****’, ’******’]

1-      (Conversions between Celsius and Fahrenheit) Write a class that contains the following two methods:

/** Convert from Celsius to Fahrenheit */

public static double celsiusToFahrenheit(double celsius)

/** Convert from Fahrenheit to Celsius */

public static double fahrenheitToCelsius(double fahrenheit)

The formula for the conversion is:

Celsius = (5.0 / 9) * (Fahrenheit – 32)

Fahrenheit = (9.0 / 5) * Celsius + 32

Program output should be like:

If you want to convert from Fahrenheit To Celsius press 0 vice versa press 1:

0

Enter the degree in Fahrenheit: 22

The degree in Celsius: -5.5

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.

If you want to convert from Fahrenheit To Celsius press 0 vice versa press 1:

1

Enter the degree in Celsius: 33

The degree in Celsius: 91.4

Blue Line Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $560,000 is estimated to result in $235,000 in annual pretax cost savings. The press falls in the MACRS five-year class, and it will have a salvage value at the end of the project of $94,000. The press also requires an initial investment in spare parts inventory of $29,000, along with an additional $3,400 in inventory for each succeeding year of the project. The shop’s tax rate is 35 percent and the project's required return is 9 percent. Refer to Table 8.3.

Suppose that you have been called as an expert witness for a defendant accused of robbing a bank. Prior to your being called as a witness, two bank tellers confidently identified the defendant as the robber. What research evidence might you introduce to the jury to caution them about assuming that the defendant must be guilty because he or she was identified in court?

1.         Borden Road Music is producing CDs for five (5) artists, Sarah D, Tom Boy, Uber Lyft, Vinny Joe, and Wanda, and X-terra. Borden Road Music makes the following unit profits on each artist’s CD as follows

Each artist needs recording studio time and mastering studio time. There are 10,000 Minutes of available mastering time and 25,000 minutes of available recording time.

Each artists CD must be packaged after production. There is 2,000 minutes of packaging time.

Each artist will need promotion time. There are only 50,000 minutes of promotional time available.

Marketing has the following consumer behavior information:

            i.          There are already 200 copies of Uber Lyft CDs pre-ordered.

            ii.         There are already 100 copies of Vinny Joe CDs pre-ordered.

            iii.       For every 2 Sarah D CDs sold there is a Tom Boy CD sold.

As a quality control measure Wanda CDs cannot exceed half of the other CDs produced.

a.         Formulate the standard form of Borden Road Music’s linear program in the table below.

b.         Use excel to solve the linear program and attach the Solution worksheet, the Sensitivity Analysis worksheet.

c.         What happens to Borden Road’s profits if they gain 100 minutes of Mastering time?

            Profits:                                           .

d.         What happens to Borden Road’s profits if they lose 100 minutes of recording time?

You are one of the developers on a team of 10 working in-house for a large corporation. You've been working on a new "Press Releases" page on your company's website for a few weeks. The project involves the company's Public Relations department, and the company's Social Media team. The purpose of the page is to share the company's most recent press release, and includes a list of the company's officers, and their photos. One of those company officers, the Chief Financial Officer, communicates directly to you that they would like to include an archive of the last 10 years' worth of press releases.

PLEASE WRITE 2 PARAGRAPHS TO THE FOLLOWING QUESTIONS AND EXPLAIN YOUR RESPONSES TO THE SCENERIO:

Regardless of what you think of this idea personally, what action would you take - would you implement their request and add the 10 years' worth of press releases in an Archive on the new Press Releases page as requested? Would you consult your contacts in the PR & Social Media department first? Would you refer the CFO to a project manager? Some combination of those?

Consider the following given information, determine the 3-year moving averages that would have been used to forecast the sales (in millions) for the years subsequent to each group of three years. Determine the forecast error associated with each forecast.

Year(t) 1993／ 1994 ／1995 ／1996 ／1997 ／1998 ／1999 ／2000

Profit Y(t) 0.9 ／ 1.1 ／1.2 ／ 1.3 ／ 1.4 ／ 1.5 ／ 1.6 ／ 1.7

You may create a table with below information.

Year ／ Sales in millions ／ 3-year Moving Forecast ／ Forecast error ／ Absolute error

b) In the below table, by using the actual level of sales for 1994 of 1.1 million dollars as the “seed” forecast for 1995, determine the forecast for each annual sales amount by the method of simple exponential smoothing. First use a smoothing constant of alpha = 0.8, then use a smoothing constant of alpha = 0.2, and compare the two sets of forecasts.

Year(t) 1993 /1994 /1995 /1996 /1997 /1998 /1999 /2000

Sales in millions Y(t) 0.9 /1.1 /1.5 /1.3 /1.1 /1.7 /1.9 /2.3
