Your portfolio consists of an index mutual fund which represents the overall market and Treasury bills. The mutual fund has a po

pshichka [43]

Answer:

8.01%

Explanation:

Expected return on mutual fund = Risk-free rate + Market risk premium*Beta

Expected return on mutual fund = 3% + 7.7%*1

Expected return on mutual fund = 10.70%

Best estimate of the portfolio expected rate of return = Weight of mutual fund*Expected return on mutual fund + Weight of risk-free Treasury bills*Expected return on risk-free Treasury bills

Best estimate of the portfolio expected rate of return = 65%*10.70 + 35%*3

Best estimate of the portfolio expected rate of return = 0.08005

Best estimate of the portfolio expected rate of return = 8.01%

ivann1987 [24]

Answer:

The answer to this question is A. Interaction between a private party and another private party

Explanation:

A free market economy, otherwise known as a capitalist economy is one that is controlled by private individuals with little or no government control.

A free or capitalist system may be defined as one in which all or most means of production are owned and controlled by private individuals and in which the economic activity of the government is at minimum.

In a capitalist economic system, private individuals play greater role than the government in taking decision about on what to produce, how to produce and the distribution of what is produced.

Hence, the allocation of benefits and costs is determined in a free market economy by A. Interaction between a private party and another private party

For an analysis of the salaries of your company, you plot the salaries of all employees against the number of years they have w

Arisa [49]

Answer:

1. That values that you must plot are:

(1, 4.08))

(20, 5.08)

(40, 6.18)

2. Yes, the plot of those three points is straight enough.

Explanation:

A. What are the values you will plot?

The x-ccordinate of your plot is still the number of years the exmployees have worked for the company.

The y-coordinate of your plot is the the base-10 logarithm of the salary.

Therefore:

1) A part-time shipping clerk: 1 year, $12,000

⇒ $(1,log_{10}12,000)=(1,4.08)$

2) A manager: 20 years, $120,000

⇒ $(20,log_{10}120,000)=(20,5.08)$

3) The CEO: 40 years ago, $1,500,000

⇒ $(40,log_{10}1,500,000)=(40,6.18)$

Summarizing, the points to plot are:

(1, 4.08)

(20, 5.08)

(40, 6.18)

B. Will the plot of these three points be straight enough?

To find whether the plot is straight enoguh, you may either plot them, make a regression, or, since they are only three points, you can whether the change of rate of the points is constant.

Change of rate of the first two points, r:

r = rise/run = Δy / Δx = (5.08 - 4.08) / (20 - 1) =1.00/19 ≈ 0.05

Change of rate of the second and the third points, r:

r = rise/run = Δy / Δx = (6.18 - 5.08) / (20 - 1) = 0.05

Since both rate of changes are equal (or reasonably equal) the plot is straight enough.
