Answer:

0.1640 ≤ p ≤0.3532

Explanation:

Sample size (N) = 58 customers

Z-score for 90% interval (Z) = 1.645

The proportion of customers that received some cash back is given by:

p=\frac{15}{58}\\p=0.2586

The confidence interval for the proportion of all depositors who ask for cash back is determined by the following relationship:

p\pm Z*\sqrt{\frac{p*(1-p)}{N}}

Applying the given data:

0.2586\pm 1.645*\sqrt{\frac{0.2586*(1-0.2586)}{58}}\\0.2586\pm0.0946

The upper and lower limits are:

L=0.2586-0.0946\\L =0.1640 \\L=0.2586-0.0946\\L = 0.3532

Using a 90% confidence level, the interval for the proportion (p) is:

0.1640 ≤ p ≤0.3532

Computech Corporation is expanding rapidly and currently needs to retain all of its earnings; hence, it does not pay dividends.
Arturiano [62]

Answer: $8.81

Explanation:

To solve this, add the present values of the dividends from years 3, 4 and 5 and then add the present value of the terminal value of the stock at year 5.

Year 3 dividend = $0.50

Year 4 dividend = 0.50 * (1 + 49%) = $0.745

Year 5 dividend = 0.745 * 1.49 = $1.11005

= Dividend in year 3 / (1 + required rate of return)³ + Dividend in year 4 / (1 + required rate of return)⁴ + Dividend in year 5 / (1 + required rate of return)⁵ +   (Dividend in year 5 * (1 + growth rate) / ( required rate of return - growth rate ) ) / (1 + required rate of return)⁵

= 0.5 / 1.16³ + 0.745/1.16⁴ + 1.11005/1.16⁵ + ( 1.11005 / (16% - 9%)) / 1.16⁵

= $8.81

In the short run a) a firm does not have sufficient time to change any of the resources it uses. b) a firm does not have suffici
timama [110]

Answer:

c) a firm does not have sufficient time to change the level of use some of its inputs.

Explanation:

The definition of short-run in economics is not a term to be used for a specific certain period of time but it means that the period of time is too short that the firms cannot change the level they are using of some of their inputs or costs. It means they do have fixed costs they cannot change. For example, all machinery installed, a yearly rent paid, electricity or others that the firm cannot change unless there is sufficient time. In a short period of time, it will have those costs anyway. The firm cannot change the level of that input. And it is short run of at least one input. It may be many. But it is not necessary to have all inputs unchanged to consider that period of time as short-run.

However, firms can change level of inputs if they have more time. That is cost the long run. All costs are variable costs when we are in long run.

bezimeni [28]

If the internal rate of return is used as the discount rate in the net present value calculations, the net present value will be  equal to zero. The internal rate of return (IRR) is a financial analysis metric used to estimate the profitability of potential investments.

The IRR calculations use the same formula as NPV calculations. Keep in mind that the IRR is not the project's actual the dollar value. The annual return is what brings the NPV to zero. The IRR is calculated in the same way as net present value (NPV), except that it sets NPV to zero.
