20,000 records should be looked

Solution:

Solve for s :  50 = [1.96*s/0.5]

25 = 1.96s

s = 12.75

Solve for "n":  n = [1.96*12.75/0.25]^2

n = [100]^2

n = 20,000

CAPM and Valuation. You are considering acquiring a firm that you believe can generate expected cash flows of $10,000 a year for
UkoKoshka [18]

Answer:

The value of the firm or worth of the firm is $147058.82 rounded off to 2 decimal places

Explanation:

We first need to calculate the required rate of return for this firm that will be used as the discount rate in the valuation of the firm using the discounted cash flow methods.

Using the CAPM we can calculate the required rate of return as,

r = rRF + Beta * (rM - rRF)

Where,

  • rRF is the risk free rate
  • rM is the return on Market

So,

r = 0.04 + 0.4 * (0.11 - 0.04)

r = 0.068 or 6.8%

As the cash flows the firm can generate are expected to remain constant through out and they are generated after equal interval of time, this can be treated as a perpetuity.

The present value of a perpetuity is calculated as follows,

Present Value of perpetuity = Cash Flow / r

Present value of perpetuity = 10000 / 0.068

Present value of perpetuity = $147058.8235

So, the value of the firm or worth of the firm is $147058.82 rounded off to 2 decimal places

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.

Nesterboy [21]

Answer:

The correct word that fills the gap is: sales.

Explanation:

Initially, the Marketing approach was productive, towards production: Marketing aims to achieve greater efficiency in the financial and productive areas of the company.

Subsequently, the emphasis was on the product, but the growing competition and the difficulty of selling production, changed the focus towards sales, the goal was to sell above all and reduce inventories.

Subsequently, the focus is increasingly shifted to the consumer: consumers do not acquire production plants, products or services, buy benefits and utilities, the "expectations of meeting their different needs." The current approach is market-oriented, where the consumer and their needs remain the key, and therefore the competition must also be analyzed, which tries to satisfy the same customer as us. Likewise, the environment that conditions this process and any other critical factor must also be analyzed.
