The purpose of this question is to practice the pthread built in functions.

The following c program is a simple program to make a matrix of integers and print it.

//File name: a.c

#include <stdio.h>

#include <time.h>

#include <stdlib.h>

int** a;

int main(){

time_t t;

int m, n, i, j;       //m is the numbers of rows and n is the number of columns.

printf("Enter the number of rows, and columns: ");

scanf("%d%d", &m, &n);

printf("%d, %d\n", m, n);

srand((unsigned) time(&t));

a=(int**) malloc(m*sizeof(int*));

for(j = 0; j < n; j++)

    a[j] = (int*) malloc(n * sizeof(int*));

for(i = 0; i < m; i++)

    for(j = 0; j < n; j++)

      a[i][j] = rand() % 1000;

for(i = 0; i < m; i++){

    for(j = 0; j < n; j++)

      printf("%d,", a[i][j]);

    printf("\n");

Your project uses pthread built-in functions based on the following conditions:

1. The program reads from the console the number of rows and the number of columns (like the above program). Therefore, the matrix has m rows and n columns.

2. The program creates m threads.

3. Each thread assigns random numbers to one row of the matrix.

4. The function main, sorts each row.

5. Each thread displays its sorted row.

6. The function: main displays the entire matrix.

Answer: ?

A petrochemical plant was built by a river. To verify whether the plant was contributing to pollution of the river water with benzo(a)pyrene, two sets of data were obtained by analyzing water samples from upstream ( mean conc. = 0.95ppb; n=5; s=0.05 ppb) and downstream (mean conc.= 1.10 ppb; n=6; s=0.08ppb) with respect to the plant. Based on this data, one would reach this conclusion at a 95% confidence level as to whether the plant is making significant contribution of benzo(a)pyrene pollution of the river water.

A) The contribution is significant.

B) The contribution is not.

C) More data is needed to reach a conclusion

D) none of the above

C) 1.18 x 10^-12 mol/L

D) None of the above

The active management industry is built on the notion that in exchange for paying a fee to active managers (say 1% of your investment), you can earn an excess return by investing with them. Explain what an excess return is, how it is measured, and discuss which form or forms of the efficient market hypothesis you must believe in (and why) in order for it to make sense to invest with an active manager.

Answer:

This unit will introduce you to the multitude of factors in the built environment that play a role in physical activity behavior. The environments in which we live work and play have varying levels of support for physical activity. This unit will help you to understand both barriers and facilitators to physical activity participation within the built environment and think about how we can have a positive impact on the spaces in which we commonly spend time.

Discuss:

1. The article "The Role of the Built Environments in Physical Activity, Obesity, and CVD" presents as ecological model of four domains of physical activity. The push is to create multi-level, multi-sector approaches to physical activity promotion. Describe a physical activity intervention/program you are aware of. Describe it and then share what domains, levels, and sectors of the ecological model it reached and which it didn't reach. Is there evidence to show this intervention/program was successful/unsuccessful? What do you know about its effectiveness? Are there things that you believe would improve it and help it be more impactful? Describe, support, and discuss.

2. In the Robert Wood Johnson Research Brief on Physical Activity and the Built Environment, it discusses how car-reliance has increased and individuals walking to work has decreased. Find information to support why this shift has occurred and if there are successful approaches out there to increase active transportation. Pretend you were just hired by the SDSU wellness center to increase active transportation within the SDSU community. Based on the research you found on the topic, what would we need to do in the SDSU campus community to decrease the number of students who drive to class and increase the number who walk/ride a bike to class? Support your idea with evidence based information. Mark Fenton will get you thinking about factors to consider as a starting point in his videos.

Problem 6-20 CVP Applications: Break-Even Analysis; Cost Structure; Target Sales [LO6-1, LO6-3, LO6-4, LO6-5, LO6-6, LO6-8]

Northwood Company manufactures basketballs. The company has a ball that sells for $25. At present, the ball is manufactured in a small plant that relies heavily on direct labor workers. Thus, variable expenses are high, totaling $15.00 per ball, of which 60% is direct labor cost.

Last year, the company sold 36,000 of these balls, with the following results:

Required:

1. Compute (a) last year's CM ratio and the break-even point in balls, and (b) the degree of operating leverage at last year’s sales level.

2. Due to an increase in labor rates, the company estimates that next year's variable expenses will increase by $3.00 per ball. If this change takes place and the selling price per ball remains constant at $25.00, what will be next year's CM ratio and the break-even point in balls?

3. Refer to the data in (2) above. If the expected change in variable expenses takes place, how many balls will have to be sold next year to earn the same net operating income, $97,000, as last year?

4. Refer again to the data in (2) above. The president feels that the company must raise the selling price of its basketballs. If Northwood Company wants to maintain the same CM ratio as last year (as computed in requirement 1a), what selling price per ball must it charge next year to cover the increased labor costs?

5. Refer to the original data. The company is discussing the construction of a new, automated manufacturing plant. The new plant would slash variable expenses per ball by 40.00%, but it would cause fixed expenses per year to double. If the new plant is built, what would be the company’s new CM ratio and new break-even point in balls?

6. Refer to the data in (5) above.

a. If the new plant is built, how many balls will have to be sold next year to earn the same net operating income, $97,000, as last year?

b. Assume the new plant is built and that next year the company manufactures and sells 36,000 balls (the same number as sold last year). Prepare a contribution format income statement and compute the degree of operating leverage.

ANSWER 5-6B

5. Refer to the original data. The company is discussing the construction of a new, automated manufacturing plant. The new plant would slash variable expenses per ball by 40.00%, but it would cause fixed expenses per year to double. If the new plant is built, what would be the company’s new CM ratio and new break-even point in balls? (Round "CM Ratio" to 2 decimal places and "Unit sales to break even" to the nearest whole unit.)

6.

If the new plant is built, how many balls will have to be sold next year to earn the same net operating income, $97,000, as last year? (Round your answer to the nearest whole unit.)

The catering manager of LaVista Hotel, Lisa Ferguson, is disturbed by the amount of silverware she is losing every week. Last Friday night, when her crew tried to set up for a banquet, they did not have enough knives. She decides she needs to order some more silverware, but wants to take advantage of any quantity discounts her vendor will offer.

>For a small order (2,000 pieces or less) her vendor quotes a price of $1.80/piece.

>If she orders 2,001 to 5,000 pieces, the price drops to $1.60/piece.

>5,001 to 10,000 pieces brings the price to $1.40/piece, and

>10,001 and above reduces the price to $1.25/piece.

Lisa's order costs of $205 per order, her annual holding costs are 5%, and the annual demand is 44,600 pieces. For the best option, (the best option is the price leve that results in an EOQ within the acceptable range).

A) What is the optimum ordering quantity?

B) What is the annual holding cost?

C) What is the annual ordering cost?

D) What are the annual cost of the silverware with an optimal order quantity?

E) What is the total annual cost, including ordering, holding, and purchasing the silverware?
