Answer:

The probability more than 72% of the cardholders are carrying a balance is 0.2946

Explanation:

Test statistic (z) = (p' - p) ÷ sqrt[p(1-p) ÷ n]

p' is the sample proportion = 0.72

p is the population proportion = 0.74

n is the number of cardholders sampled = 140

z = (0.72 - 0.74) ÷ sqrt[0.74(1-0.74) ÷ 140] = -0.02 ÷ 0.037 = -0.54

The cumulative area of the test statistic is the probability that less than 72% of the cardholders are carrying a balance. The probability is 0.7054.

Probability (more than 72% of the cardholders are carrying a balance) = 1 - 0.7054 = 0.2946

A company has the following per unit recorded cost and replacement cost relating to its inventory:Item 1 5 units Cost $50 Market
Kryger [21]

The reported value of this company's ending inventory if LCM is applied to individual items is $870.

<h3>What is reported value?</h3>

The value of any assets or liabilities or any such credentials, which is recorded in the books of official record for the purpose of accounting as per the standards, is known as the reported value.

The computation of the reported value in the given condition will be,

  1. Item 1 – 5 Units x $45= $225;
  2. Item 2 – 7 units x $60= $420;
  3. Item 3 – 9 Units x $25= $225.

The summation of all the reported values will be,

$(225+420+225)= $870.

Hence, the reported value of the inventory of the company is as aforementioned.

Suppose that the equation for the SML is Y = 0.05 + 0.07X, where Y is the average expected rate of return, 0.05 is the vertical
timurjin [86]

Answer:

Risk free interest rate is 5%

Y is 15.5% at a Beta of 1.5

X is 0.29 when Y is 7%

Explanation:

Risk free interest is 0.05 which 5% as given in the equation

The average expected return is given by Y

Y=0.05+0.07X

Since Beta is the same as X, when equals 1.5,Y is calculated thus

Y=0.05+0.07(1.5)

Y=0.05+0.105

Y=0.155

Y=15.5%

The value of Beta at an average return of 7% is computed thus:

7%=0.05+0.07X

where X is the unknown

0.07=0.05+0.07X

0.07-0.05=0.07X

0.02=0.07X

X=0.02/0.07

X=0.29

The scenario  illustrates that the Beta, which is the risk of investment and the Y , the expected average return are positively correlated.

If the number of potential workers in an economy increases while the size of the labor force remains​ unchanged, ________. A. th
galben [10]

Answer:

<h2>The answer here would be option C. from the answer list or options given in the question which is the labor force participation rate will fall.</h2>

Explanation:

  • Labor force participation rate basically reflects the total or overall number of people who are actively participating the labor or work force in the economy and are actually qualified and eligible to be officially part of the work or labor force.
  • Hence,even if the number of eligible and qualified people or workers in the economy potentially increases and the overall size of the work or labor force remains constant,it essentially implies that much of the eligible and qualified laborers or workers is either unemployed or has not been properly mobilized or utilized in the labor or work force in the economy.It can also indicate that majority of the people who are presently participating in the labor force are not eligible or fully qualified as per their occupational or professional designation.
  • Therefore,in this instance the labor force participation rate will decline as the overall proportion of employment of the eligible and qualified laborers or workers does not really increase in the economy.Therefore,even if the number of potential workers or the labor resource increase in the economy,it has not been properly or completely utilized or employed in the overall labor force.
