Answer:

Option C) 1537

Explanation:

We are given the following in the question:

Population standard deviation = $5000

95% confidence interval width = $500

Thus, margin of error = $250

Formula for margin of error =

z_{stat}\times \dfrac{\sigma}{\sqrt{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting values, we get,

250 = 1.96\times \dfrac{5000}{\sqrt{n}}\\\\n = (1.96\times \dfrac{5000}{250})^2\\\\n = 1536.64\\n \approx 1537

Thus, the correct answer is

Option C) 1537

Marina86 [1]

Answer:

The answer is "1.1"

Explanation:

In the case of a single Interest, the principal value is determined as follows:

\ I = Prt \\\ A = P + I\\A = P(1+rt) \\\\A = amount \\P= principle\\r = rate\\t= time

In case of discount:

D = Mrt \\P = M - D \\P = M(1-rt)\\\\Where,  D= discount \\M =\  Maturity  \ value \\

Let income amount = 100, time = 1.5 years, and rate =20 %.

Formula:

A = P(1+rt)  

A =P+I

by putting vale in the above formula we get the value that is = 76.92, thus method A will give 76.92  value.

If we calculate discount then the formula is:

P = M(1-rt)

M = 100  rate and time is same as above.

P = 100(1-0.2 \times 1.5) \\P = 100 \times \frac{70}{100} \\P = 70

Thus Method B will give the value that is 70  

calculating ratio value:

ratio = \frac{\ method\  A \ value} {\ method \ B \ value}\\\\\Rightarrow ratio = \frac{76.92}{70}\\\\\Rightarrow ratio = \frac{7692}{7000}\\\\\Rightarrow ratio = 1.098 \ \ \ \  or \ \ \ \  1.

Fama’s Llamas has a WACC of 9.7 percent. The company’s cost of equity is 12 percent, and its pretax cost of debt is 7.5 percent.
Bezzdna [24]

Answer:

0.4766

Explanation:

Given:

WACC = 9.7%

Company’s cost of equity = 12%

Pretax cost of debt = 7.5%

Tax rate = 35%

Now,

WACC

=  Weight × Cost of equity + (1 - weight) × Pretax cost of debt × (1-tax rate)

or

0.097 = weight × 0.12 + ( 1 - weight ) × 0.075 × (1 - 0.35)

or

0.097 = 0.12 × weight + 0.04875 - 0.04875 × weight

or

0.04825 = 0.07125 × weight

or

weight = 0.6772

also,

weight = \frac{\textup{Equity}}{\textup{Debt + Equity}}

or

\frac{\textup{1}}{\textup{weight}}  = \frac{\textup{Debt+equity}}{\textup{Equity}}

or

\frac{1}{0.6772} = \frac{\textup{Debt}}{\textup{Equity}}  + 1

or

1.4766 = \frac{\textup{Debt}}{\textup{Equity}}  + 1

or

\frac{\textup{Debt}}{\textup{Equity}}  = 0.4766

hram777 [196]

Answer:

Salaries and wages payable...................Dr                    $20,000

                                      Salaries and wages expense                  $20,000

Explanation:

As per accrual system, an expense is incurred when it is accrued irrespective of when it is paid. So, $20,000 was accrued in December 31, salary and wages expenses would have been debited then amounting to $20,000.

In order to rectify the mistake of double counting, the entry passed by the accountant would be reversed to nullify the effect.

Adjusting Journal entry:

Particulars                                            Debit              Credit

Salaries and wages payable               $20,000

                 Salaries and wages expense                    $20,000

(Being double counting of salaries and
