Tony Gaddis C++ Conference Sessions An upcoming conference about C/C++ programming has three sessions planned:

- A session on the new features of C++ 17

- A session on functional programming in C/C++

- A session on lamda functions

Attendees can subscribe for any session. The organizers want to keep track of which attendees are attending which session.

Write a program that stores this information in a two-dimensional array of Booleans, where each row represents an attendee and each column represents their subscription for a session. You can restrict the program to seven attendees, resulting in a 7X3 array. The program should first have the user input the data for each attendee. Write two functions that take the array as their argument. One function should print out the number of people in each session and the other should return the number of people who subscribed to all sessions.

Sander is setting up a recording studio which will have an annual revenue of $80,000 and annual cost of $40,000. The studio will require an initial investment of $20,000. Sander’s discount rate is 10%, and income tax where he lives, is 40%. In the investment year, depreciation on all items is 50%, then 30% the following year, and 20% in the next year, which is the end of the schedule. What is the net present value after two years of recording?

1. $71,500
2. $41,000
3. $29,200
4. $49,400

Some of the key ratios for Palmerston plc and its main competitor Glebe plc are as follows.

Palmerston Glebe

Gearing 70% 10%

ROCE 25% 15%

Gross profit 40% 50%

Receivables’ collection 5 days 35 days

Payables’ payment 30 days 30 days

Explain why analysts might consider each of the ratios above to be useful. Use the ratios above to assess the financial performance and financial position of the two companies.

Suppose you play rock paper scissors against a computer:

*you gain $1 for each win

*you lose $1 for each lost

if it is a tie, nothing happens

you choose rock 50% of the time and the others 25% of the time

let x be a random variable that represents the amount of money you earn after one game.

(a) find the probability distribution of X

(b) what is your average payoff after 20 games?

(c) what is the standard deviation of the payoff after 20 games?

The information in the table below shows the total market demand for Good X. Assume the marginal cost of providing Good X is zero.

Refer to the table above. What is the Nash Equilibrium market quantity produced in a duopoly market?

1. Internal Rate of Return Method—Two Projects

Munch N’ Crunch Snack Company is considering two possible investments: a delivery truck or a bagging machine. The delivery truck would cost $44,209.44 and could be used to deliver an additional 40,000 bags of pretzels per year. Each bag of pretzels can be sold for a contribution margin of $0.38. The delivery truck operating expenses, excluding depreciation, are $0.52 per mile for 14,000 miles per year. The bagging machine would replace an old bagging machine, and its net investment cost would be $54,765. The new machine would require three fewer hours of direct labor per day. Direct labor is $15 per hour. There are 250 operating days in the year. Both the truck and the bagging machine are estimated to have seven-year lives. The minimum rate of return is 9%. However, Munch N’ Crunch has funds to invest in only one of the projects.

a. Compute the internal rate of return for each investment. Use the above table of present value of an annuity of $1. If required, round your present value factor answers to three decimal places and internal rate of return to the nearest percent.

Net Present Value Method and Present Value Index

Diamond and Turf Inc. is considering an investment in one of two machines. The sewing machine will increase productivity from sewing 110 baseballs per hour to sewing 198 per hour. The contribution margin per unit is $0.38 per baseball. Assume that any increased production of baseballs can be sold. The second machine is an automatic packing machine for the golf ball line. The packing machine will reduce packing labor cost. The labor cost saved is equivalent to $20 per hour. The sewing machine will cost $167,400, have a six-year life, and will operate for 1,400 hours per year. The packing machine will cost $85,800, have a six-year life, and will operate for 1,200 hours per year. Diamond and Turf seeks a minimum rate of return of 12% on its investments.

a. Determine the net present value for the two machines. Use the table of present values of an annuity of $1 above. Round to the nearest dollar.

b. Determine the present value index for the two machines. If required, round your answers to two decimal places.

Net Present Value—Unequal Lives

Bunker Hill Mining Company has two competing proposals: a processing mill and an electric shovel. Both pieces of equipment have an initial investment of $625,304. The net cash flows estimated for the two proposals are as follows:

The estimated residual value of the processing mill at the end of Year 4 is $270,000.

Determine which equipment should be favored, comparing the net present values of the two proposals and assuming a minimum rate of return of 15%. Use the present value table appearing above.

Question 1 (1 point)

We have two very long wires, which are parallel to each other pointing to the right in front of us. The pair of wire is horizontal. The wire closest to us carries a charge per unit length of 1mC/m and the other the opposite charge. The two wires are 1m apart and both move together at 100m/s along the wire to the right. We are looking at what happens in the middle region of the two wires (not the end). For the question pick all the right answers (there can be more than one correct answer).
