The mathematics department is considering revising how statistics is taught. In order to see if their changes will be effective in increasing student performance, they decided to run a Simulated Experiment. Previous semesters have that 10% of students receive an A in the class, 40% receive a B, and 20% receive a C. How would you assign values so you can use a Random Digit Table to run this experiment?

a) Assign 1 digit numbers as follows: 0 is A; 1, 2, 3, 4 are B; 5, 6 are C; 7, 8, 9 are D.

b) Assign 1 digit numbers as follows: 0 is A; 1, 2, 3, 4 are B; 5, 6 are C; 7, 8, 9 are other grades.

c) Assign 2 digit numbers as follows: 00-10 are A; 00-40 are B; 0-20 are C.

d) Assign 2-digit numbers as follows: 90-99 are A; 80-89 are B; 70-79 are C; 60-69 are D; and 00-59 are F.

e) This experiment cannot be simulated using a random digit table.

Perdue Company purchased equipment on April 1 for $58,320. The equipment was expected to have a useful life of three years, or 8,100 operating hours, and a residual value of $1,620. The equipment was used for 1,500 hours during Year 1, 2,800 hours in Year 2, 2,400 hours in Year 3, and 1,400 hours in Year 4.

Required:

Determine the amount of depreciation expense for the years ended December 31, Year 1, Year 2, Year 3, and Year 4, by (a) the straight-line method, (b) the units-of-activity method, and (c) the double-declining-balance method.

Note: FOR DECLINING BALANCE ONLY, round the final multiplier to four decimal places. Then round the answer for each year to the nearest whole dollar.

Use the following scenario to answer questions 1-4. Rachel likes Cliff Builder Bars and Chocolate Milk. The bars cost $2 each and the milk costs $2.5 per pint jug. Her Utility schedule is given below.

1. If Rachel has $6.50 to spend, how many Cliff Bars and Jugs of Chocolate Milk will she purchase?
   1. 1 Cliff Bar; 2 Jugs of Chocolate Milk
   2. 4 Cliff Bars; 0 Jugs of Chocolate Milk
   3. 2 Cliff Bars; 3 Jugs of Chocolate Milk
   4. 2 Cliff Bars; 1 Jug of Chocolate Milk

2. If she has $42.50 to spend, how many of each item will she purchase?
   1. 9 Cliff Bars; 8 Jugs of Chocolate Milk
   2. 8 Cliff Bars; 10 Jugs of Chocolate Milk
   3. 10 Cliff Bars; 9 Jugs of Chocolate Milk
   4. 9 Cliff Bars; 9 Jugs of Chocolate Milk

3. Assume that Rachel is willing to pay up to $5 for each Cliff Bar and $4 for each jug of chocolate milk. If Rachel has $13 to spend, what is her total consumer surplus?
   1. $12
   2. $8
   3. $15
   4. $18

4. Cliff Builder Bars are made with soy protein. Assume that a pest destroyed a good portion of the soybean crop and a virus killed large numbers of dairy cows. This increased the price of Cliff bars to $6 and chocolate milk to $5 per pint. If Rachel has $100 to spend, how many of each item will she purchase (based on her maximum willingness to pay from the previous question)?
   1. 20 Cliff Bars; 24 Jugs of Milk
   2. 25 Cliff Bars; 20 Jugs of Milk
   3. Need more information
   4. She won’t buy anything

PA11-3 Comparing, Prioritizing Multiple Projects [LO 11-1, 11-2, 11-3, 11-6] Hearne Company has a number of potential capital investments. Because these projects vary in nature, initial investment, and time horizon, management is finding it difficult to compare them. Assume straight line depreciation method is used. Project 1: Retooling Manufacturing Facility This project would require an initial investment of $5,650,000. It would generate $1,009,000 in additional net cash flow each year. The new machinery has a useful life of eight years and a salvage value of $1,192,000. Project 2: Purchase Patent for New Product The patent would cost $3,960,000, which would be fully amortized over five years. Production of this product would generate $811,800 additional annual net income for Hearne. Project 3: Purchase a New Fleet of Delivery Trucks Hearne could purchase 25 new delivery trucks at a cost of $195,000 each. The fleet would have a useful life of 10 years, and each truck would have a salvage value of $6,600. Purchasing the fleet would allow Hearne to expand its customer territory resulting in $999,380 of additional net income per year. Required:

1. Determine each project's accounting rate of return. (Round your answers to 2 decimal places.)

Annie Sweet Corporation is specialized in making wedding cakes. Customers are always required to pay a deposit equal to the full purchase price when they place orders.

The balance in its Unearned Revenue account was $14,000 at September 1, 2019 and $16,000 at September 30, 2019. How much revenue did Annie Sweet Corporation recognize during the month of September 2019?

Modify program 4-27 on page 219 as follows:

1) Add a new membership category for STUDENTS with a monthly rate of $90.00. The menu should have one more choice, and the switch statement should implement one more case.

2) The input for the number of months should be validated for 1 -36 months. No charges should be displayed for incorrect number of months. Instead, an error should be displayed similar with the one for wrong menu choice.

// This menu-driven program uses a switch statement to carry out

// the appropriate set of actions based on the user's menu choice.

#include <iostream>

#include <iomanip>

using namespace std;

int main()

// Constants for membership rates

const double ADULT_RATE = 120.0;

const double CHILD_RATE = 60.0;

const double SENIOR_RATE = 100.0;

The Lo Shu Magic Square is a grid with 3 rows and 3 columns. The Lo Shu Magic Square has the following properties:

The grid contains the numbers 1 through 9 (each number only once)

The sum of each row, each column and each diagonal are the same

In a program you can simulate a magic square using a two-dimensional array. Write a method that accepts a two-dimensional array as an argument, and determines whether the array is a Lo Shu Magic Square. Test the function in a program.

Detailed Description:

In main create two arrays:

// Create a magic two-dimensional array.

      int[][] magicArray = { {4, 9, 2},

                             {3, 5, 7},

                             {8, 1, 6} };

      // Create a normal two-dimensional array.

      int[][] normalArray = { {1, 2, 3},

                              {4, 5, 6},

                              {7, 8, 8} };

For the normalArray call showArray and then showResult. Then do the same for magicArray

showArray accepts a two-dimensional array and prints it row by row

showResult call isMagicSquare with the two-dimensional array reference as the parameter. It prints a message based on the return value which is Boolean.

The isMagicSquare method accepts a two-dimensional int array as an argument, and returns true if the array meets all the requirements of a magic square. Otherwise it returns false. You can create separate methods to checkRange (all must be from 1-9), checkUnique (see if all values are unique), checkRowSum, checkColSum, checkDiagSum. If each of these 3 return true then it is a Magic Square.

Output should be

1 2 3

4 5 6

7 8 8

This is not a Lo Shu magic square.

4 9 2

3 5 7

8 1 6

This is a Lo Shu magic square.

1. Anqi pays 45 dollars per unit of x and 30 dollars per unit of y. Her preferences are u(x, y) = x^1/2y^1/2. Anqi's income is 1800 dollars. How many units of good x should she purchase?

2 .A consumer has preferences u(x, y) = x^1/2 + y^1/2. She usually consumes 4 units of x and 4 units of y but the store has sold out of good y. How many units of good x must she consume to keep her utility unchanged?
