Answer: 332

Explanation:

Lowest value = $43,000

Highest value = $61,600

Range = ( HV - LV ) / 4

= ( $61,600 - $43,000 ) / 4

= $4650

Where p = $4650

Required sample size (n)

n = ( Za /2 × P/E )²........... equation 1

Using 95% confidence level

Za/2 = Z 1 - 0.95

= Z0.025

= 1.96 using Z-table

Substituting Z into equation 1

n = ( 1.96 × 4650/500 )²

= ( 1.96 × 9.3 )²

= 332.25

To the nearest whole number

= 332

A firm has a profit margin of 12 percent; total asset turnover of 0.55 and an equity multiplier of 2.2. What is the firm's ROA a
lutik1710 [3]

Answer:

ROA = 6.6%

ROE 14.52%

Explanation:

profit margin = net income / sale = 12%

assets turn over = sales / assets = 0.55

equity mutiplier = assets / equity = 2.2

ROE = return on equity = net income / equity

ROA = return on equity = net income / assets

we use the fraction properties to get ROE and ROA

\frac{income}{sales} \times \frac{sales}{Assets} =\frac{income}{Assets} \\ 0.12 \times 0.55 = 0.066\\

ROA = 6.6%

We apply the same property to get ROE

\frac{income}{assets} \times \frac{assets}{equity} =\frac{income}{equity} \\ 0.066 \times 2.2 = 0.14252\\

ROE = 14.52%

The aggregate demand curve
laiz [17]

Answer:

<u>B. shows planned purchase rates of goods and services at various price levels.</u>

Explanation:

  • The aggregate demand is the total demand for final goods and services in the economy over a given period of time. And is often distinguished as the effective demand curve. That is the demand for the GDP of the nation.
  • As it specifies all the goods and the services that are to be purchased at all the possible levels. Hence this demand curve shows us the real output given on the horizontal axis. Thus the curve shows the quantity of the output that is demanded and the aggregate of the all price level.

S= 2( lw + lh + wh) Solve for w <br><br> Please show your work
charle [14.2K]

You said that                             S     =  2(lw + lh + wh)

Divide each side by  2 :             S/2  =  lw + lh + wh

Subtract  'lh'  from each side:    S/2 - lh = lw + wh

Factor the right side:                S/2 - lh  =  w(l + h)

Divide each side by  (l + h) :    (S/2 - lh) / (l + h)  =  w

sleet_krkn [62]

Answer:a.

It would increase by $500,000 multiplied by the reciprocal of the required reserve ratio.

Explanation:

A bank will often hold government securities as an asset. If a bank were to sell S500,000 in government securities to an individual who paid for the bond in cash and the bank placed this cash in its vault, by how much would the money supply change as a result  -  It would increase by $500,000 multiplied by the reciprocal of the required reserve ratio.

The money supply is the entire stock of currency and other liquid instruments circulating in a country's economy and is given by the formula:

MONEY SUPPLY = RESERVES X MONEY MULTIPLIER

Therefore the bank reserves increasing in the scenario will increase money supplier by the effect of the money multiplier or the reciprocal of the required reserve ratio.
