Please explain all steps and equations, please...

Design and write a Python 3.8 program that gives and grades a math quiz. The quiz will give 2 problems for each of the arithmetic operations: +, -, *, /, and %. First, two addition problems will be presented (one at a time) with random numbers between 1 and 20. Then two subtraction problems, multiplication, division and modulus. For division use // and do floor division; for example: for 10//3, the answer should be 3. For an example of the first problem: the program generates two random numbers (let's say num1 is 17 and num2 is 5), and prints out a statement of the problem as 17 + 5 =. The user will enter a correct answer or a wrong answer. If the answer is correct, a message will be printed and one will be added to the number of correct answers. Then the second addition problem is given and checked. Next, two subtraction problems will be given and checked, and so on.

Define a function for each of the 5 operations. Each function will display 2 problems (one at a time) to be solved. The call to each function should return the number of correct answers (0, 1, or 2). After calling all 5 functions in sequence, the main program will print out the total score of that quiz, and asks the user if he/she wants to take another quiz. The main program should keep calling the 5 functions in sequence as long as the user wants to take another quiz.

Required information

[The following information applies to the questions displayed below.]

Trico Company set the following standard unit costs for its single product.

The predetermined overhead rate is based on a planned operating volume of 80% of the productive capacity of 56,000 units per quarter. The following flexible budget information is available.

During the current quarter, the company operated at 90% of capacity and produced 50,400 units of product; actual direct labor totaled 299,400 hours. Units produced were assigned the following standard costs.

Actual costs incurred during the current quarter follow.

(a) Compute the variable overhead spending and efficiency variances. (Round "cost per unit" and "rate per hour" answers to 2 decimal places.)

AH = Actual Hours
SH = Standard Hours
AVR = Actual Variable Rate
SVR = Standard Variable Rate

(b) Compute the fixed overhead spending and volume variances. (Round "cost per unit" and "rate per hour" answers to 2 decimal places.)

AH = Actual Hours
SH = Standard Hours
AFR = Actual Fixed Rate
SFR = Standard Fixed Rate

(c) Compute the total overhead controllable variance.

1. Frictional unemployment can be reduced by good economic policy. T or F

2. Price indexes are biased because some goods are improved over time. T or F

3. GDP does not include costs of pollution due to production in the period. T or F

4. The excess reserve deposit ratio is controlled by commercial banks and if the excess deposit ratio increases, the money supply also increases. T or F

5. The government debt is government spending plus transfer payments minus taxes. T or F

During 2019,Rainbow Umbrella Corp. had sales of $860,000. Cost of goods sold, administrative and selling expenses, and depreciation expenses were $680,000, $85,000, and $180,000, respectively. In addition, the company had an interest expense of $55,000 and a tax rate of 21 percent. (Assume that interest is fully deductible.) Suppose the company paid out $65,000 in cash dividends. If spending on net fixed assets and net working capital was zero, and if no new stock was issued during the year, what was the net new long-term debt?

Q30. When an insect infestation wipes out cotton crops in the south, consumer prices for cotton-based goods ____ while cotton production in other regions ____.

decreases, decrease

increase, increases

decreases, increase

increases, decrease

Q31. When a budget drops into deficit, a government can attempt to plug the gap by ____.

borrowing, cutting spending, raising taxes, all of the above

Q38. Discretionary fiscal policy is limited by the fact that ____ of the federal budget is non-discretionary.

80% - 100%

0% - 20%

20% - 40%

60% - 80%

3. Define GDP. Explain the various methods of calculating GDP.

So, GDP is the total value of goods produced and services provided in a country during one year. For the gross domestic product, “gross” means that the GDP measures production regardless of the various uses to which the product can be put.

I know that one method is the Expenditure method:

GDP = private consumption + gross investment + government investment + government spending + (exports – imports).

I need 1 or 2 more methods, but do not know what they are.

Suppose the government is concerned with its large trade deficit. Politician A proposes to encourage consumers to buy more domestically produced goods by running "Buy American" marketing campaigns. Politician B proposes to reduce government spending in order to tackle government debt.

A.) How does Politician A's plan affect the trade deficit and why?

B.) How does Politician B's plan affect the trade deficit and why?

C.) Which of these two policy choices, if any, will be effective in reducing the trade deficit in the long run?

The production department of Zan Corporation has submitted the following forecast of units to be produced by quarter for the upcoming fiscal year:

In addition, 24,500 grams of raw materials inventory is on hand at the start of the 1st Quarter and the beginning accounts payable for the 1st Quarter is $6,600.

Each unit requires 7 grams of raw material that costs $1.40 per gram. Management desires to end each quarter with an inventory of raw materials equal to 25% of the following quarter’s production needs. The desired ending inventory for the 4th Quarter is 7,000 grams. Management plans to pay for 60% of raw material purchases in the quarter acquired and 40% in the following quarter. Each unit requires 0.40 direct labor-hours and direct laborers are paid $15.50 per hour.

Required:

1.&2. Calculate the estimated grams of raw material that need to be purchased and the cost of raw material purchases for each quarter and for the year as a whole.

3. Calculate the expected cash disbursements for purchases of materials for each quarter and for the year as a whole.

4. Calculate the estimated direct labor cost for each quarter and for the year as a whole. Assume that the direct labor workforce is adjusted each quarter to match the number of hours required to produce the estimated number of units produced.
