Assume the random variable x is distributed with mean of 50 and a standard deviation of 7. Compute the probability.
P(x > 38)

To solve this problem, we can use the formula for inverse variation, which is:

time = k/ rate

where k is a constant of proportionality.

We can start by finding the value of k using the given information. We know that when the pumping rate is 400 gallons per hour, it takes 12 hours to drain the pool. Therefore:

12 = k/400

Multiplying both sides by 400 gives us:

k = 4800

Now we can use this value of k to answer the second part of the question. We want to know how many hours faster the pool can be drained if the pumping rate is increased to 500 gallons per hour. Let's call this new time t:

t = 4800/500

t = 9.6 hours

So the pool can be drained 12 - 9.6 = 2.4 hours faster if the pumping rate is increased to 500 gallons per hour.

The length of the third side is 8units

Pythagoras theorem states that : the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

If a and b are the legs of the triangle and c is the hypotenuse,then

c² = a²+b²

For example , if a = 3 and b = 4 , then

c = √3²+4²

c = √ 9+16

c = √25

c = 5units.

Similarly, c = 10, a= 6, and b is unknown

therefore

10²= 6²+b²

b² = 10²-6²

b² = 100-36

Answer:

Private saving (Sprivate) is equal to disposable income minus consumption:

Sprivate = Y - T - C = 15,000 - 3,000 - 9,000 = 3,000

Public saving (Spublic) is equal to government revenue minus government spending:

Spublic = T - G = 3,000 - 3,600 = -600

National saving (S) is equal to the sum of private and public saving:

S = Sprivate + Spublic = 3,000 - 600 = 2,400

Investment (I) is given by the investment function:

I = 3,900 - 100r

Equating investment to national saving gives:

I = S

3,900 - 100r = 2,400

Solving for r:

r = 15%

Therefore, the equilibrium real interest rate is 15%.

Substituting r = 15% into the investment function gives:

I = 2,400

Therefore, investment is 2,400.

Finally, to determine if the government has a budget surplus or deficit, we need to calculate the government's budget balance, which is equal to government revenue minus government spending:

Budget balance = T - G = 3,000 - 3,600 = -600

Since the budget balance is negative, the government of Flatland has a budget deficit.

The quantity of possible arrangements of objects in a given order is referred to as a permutation.

Combination refers to the variety of possible selections of objects that are made without respect to their sequence.

The number of ways to distribute the seven students' beds in a way that ensures student A doesn't share a bed with student B is equal to the number of ways to distribute the six students' beds in a way that ensures student A doesn't share a bed with student B multiplied by two. (since there are two possible positions for student B).

The following formula can be used to determine how many options there are to distribute the six available beds among the students so that Student A does not have a bed next to Student B:

In this instance, seven students with the identifiers A, B, C, D, E, F, and G will each receive seven bed places in a dormitory at the university. Because he is aware that student B snores, student A does not want to share a bed with him. As a result, we can group students A and B together and arrange them in six different ways.

Then we can arrange the remaining students C, D, E, F and G in 5! ways. Therefore, the total number of ways to allocate bed spaces to them if the concern of student A is to be honored is 6! * 5! = 17,280 .

The true statement is that the difference between the maximum profit earned by the sandwich shop and the smoothie stand is $2,700. (option d).

To determine the maximum profit earned by each business, we need to find the vertex of each quadratic function. The vertex of a quadratic function of the form ax² + bx + c is given by the formula (-b/2a, f(-b/2a)), where f(-b/2a) is the maximum value of the function.

The equations for the two functions are:

f(x) = -500x² + 9000x + 7500 g(x) = -500x² + 7500x + 4200

To find the vertex of f(x), we need to first rewrite the function in standard form:

f(x) = -500(x² - 18x - 15)

Completing the square, we get:

f(x) = -500(x - 9)² + 12000

So the vertex of f(x) is (9, 12000), which represents the maximum profit earned by the sandwich shop.

Similarly, to find the vertex of g(x), we rewrite the function in standard form:

g(x) = -500(x² - 15x - 8.4)

Completing the square, we get:

g(x) = -500(x - 7.5)² + 14100

So the vertex of g(x) is (7.5, 14100), which represents the maximum profit earned by the smoothie stand.

Finally, we can calculate the difference between the maximum profits earned by both businesses as:

12000 - 14100 = -2700

Answer: Let's first convert Cheryl's walking speed to meters per minute. Since she takes 80 steps per minute and each step is 81 cm, her walking speed is:

80 steps/min x 81 cm/step = 6480 cm/min

To convert this to meters per minute, we can divide by 100:

6480 cm/min ÷ 100 cm/m = 64.8 m/min

Now, let's find out the distance Cheryl walks to school. Since she walks for 12 minutes at a speed of 64.8 m/min, the distance she covers is:

distance = speed x time = 64.8 m/min x 12 min = 777.6 m

Next, let's find out how many steps Diane takes per minute on average:

90 steps/min

Since each of Diane's steps is 72 cm long, her walking speed is:

90 steps/min x 72 cm/step = 6480 cm/min

To convert this to meters per minute, we can divide by 100:

6480 cm/min ÷ 100 cm/m = 64.8 m/min

So Diane's walking speed is the same as Cheryl's. To find out how long it takes Diane to walk to school, we can use the formula:

distance = speed x time

Since Diane and Cheryl walked the same distance, we can use the distance we found for Cheryl:

777.6 m = 64.8 m/min x time

Simplifying this equation, we get:

time = 12 minutes

Therefore, Diane takes 12 minutes to walk to school.

Answer:

  12 min

Step-by-step explanation:

You want to know how long it takes Diane to walk to school if she takes 90 steps of 72 cm per minute, while Cherly takes 80 steps of 81 cm per minute and traverses the distance in 12 minutes.

The speed of each girl is the product of the number of steps per minute and the length of the step:

  Cheryl: (80 step/min)(81 cm) = 6480 cm/min

  Diane: (90 step/min)(72 cm) = 6480 cm/min

Both girls travel at the same speed, so will take the same amount of time to get to school. It takes Diane 12 minutes to walk to school.

1.Ongoing efforts have been undertaken in Malaysia to improve the financial reporting and accountability in government agencies. Discuss the efforts.

Malaysia has been making efforts to improve financial reporting and accountability in government agencies for several years. In 2015, the Malaysian government introduced a new financial reporting framework for government agencies called the Malaysian Public Sector Accounting Standards (MPSAS). This framework is designed to improve financial reporting and ensure that government agencies are held accountable for their financial performance.

The MPSAS framework is based on international accounting standards and is meant to increase transparency and consistency in financial reporting. It includes guidelines for budgeting, financial management, and reporting of financial performance. Additionally, the Malaysian government has established the Accountant General's Department, which is responsible for overseeing financial reporting in government agencies.

Other initiatives aimed at improving financial reporting and accountability in Malaysia include the implementation of electronic financial management systems, the introduction of new financial management guidelines, and the establishment of a Financial Management Committee to oversee financial management across all government agencies.

2.Discuss the extent of application for the key accounting concepts in the public sector.

The key accounting concepts that are applicable to the public sector are similar to those used in the private sector, with some important differences. One of the key differences is that in the public sector, accounting practices are focused on ensuring accountability to the public and ensuring that public funds are used responsibly.

Some of the key accounting concepts that are applicable in the public sector include accrual accounting, budgeting, and financial reporting. Accrual accounting is used to record financial transactions as they occur, regardless of when payment is made or received. This helps to ensure that all financial transactions are recorded accurately and transparently.

Budgeting is also an important accounting concept in the public sector. Governments typically create budgets to allocate funds to various programs and projects. These budgets are then used to monitor financial performance and ensure that resources are used efficiently.

Financial reporting is another key accounting concept in the public sector. Governments are required to report on their financial performance to ensure transparency and accountability. This includes reporting on revenue and expenses, assets and liabilities, and cash flow.

3.Clearly describe the regulatory framework and procedures for financial reporting in the public sector.

The regulatory framework for financial reporting in the public sector typically involves a combination of national and international accounting standards. In Malaysia, the regulatory framework is based on the Malaysian Public Sector Accounting Standards (MPSAS), which are based on international accounting standards.

Under this framework, government agencies are required to prepare financial statements in accordance with MPSAS. These statements include the statement of financial position, statement of financial performance, statement of changes in equity, and statement of cash flows.

Additionally, the Accountant General's Department is responsible for overseeing financial reporting in government agencies. They are responsible for ensuring compliance with MPSAS and for providing guidance on financial reporting issues.

Government agencies in Malaysia are required to submit their financial statements to the Accountant General's Department for review and approval. Once approved, these statements are published and made available to the public.

Overall, the regulatory framework and procedures for financial reporting in the public sector are designed to ensure transparency and accountability in the use of public funds.

The savings amount balance in the account is $ 467.39

Given data ,

You just opened a savings account and deposited $300 at 3% that you plan on withdrawing in 15 years.

Using the formula FV = PV * (1 + i)^n, where FV is the future value, PV is the present value, i is the interest rate, and n is the number of periods, we can calculate the future value of the savings account after 15 years.

PV = $300 (the initial deposit)
