The following table provides two risky assets for you to construct the investment opportunity sets based on the given correlation information.

Constructing investment opportunity sets

Complete the table of Risks and Returns of all the possible combinations.

For each correlation situation, insert a “Mean-Standard Deviation” chart and plotting the investment opportunity sets with varying weights on the two risky assets, then connecting the dots to show the curvature of each investment set.

Given a risk-free of 3%, draw a capital allocation line (CAL) to connect the risk-free rate and the “optimal portfolio” point on each curvature chart.

Please complete on excel and show work

Business Law

Case Scenario:

Ashley met Adam at a party and after a couple of drinks; Ashley found out that Adam is in the business of selling education products.

Compare and contrast the different liabilities for Ashley and Adam in each of the following different situations, where Ashley is buying, and Adam is selling and they are about to or have entered into a contract.

Q# a. Both parties discussed their intentions and Ashley stated what kind of education products she was interested in. However, they parted ways after that. Ashley said later that there was no contract between them but Adam stated that Ashley has already reserved the products she wanted with him.

In each of the following situations, Emma is in the exact center of a glass-sided fright car speeding to the right at a very high speed v relative to you. For each question, explain your reasoning.

Emma has a flashlight in each hand and directs them at the front and rear ends of the freight car. She then switches the flashlights on at the same time.

In Emma�s frame of reference, which beam of light travels at a greater speed, the one directed toward the front or the one directed toward the rear of the train, or do they travel at the same speed?

In Emma�s frame of reference, which end, front or rear, is struck by light first, or are they struck at the same time? Which end is struck first in your frame of reference?

An educational researcher wishes to know if there is a difference in academic performance for college freshmen that live on campus and those that commute. Data was collected from 267 students. Can we conclude that freshman housing location and academic performance are related? Location Average Below Average Above Average Total On campus 89 29 27 145 Off campus 36 43 43 122 Total 125 72 70 267 Copy Data Step 2 of 8 : Find the expected value for the number of students that live on campus and have academic performance that is average. Round your answer to one decimal place.

Regulation of the lac operon is under both negative and positive control. Describe how these two transcriptional control mechanisms regulate expression of the lac operon in the presence of glucose and/or lactose.

A high carbon steel shaft is used in an engine and subjected to different loads. In order to
analyse the stress in the shaft, consider a rectangular element within the material. This
element is subjected to compressive stress of 135 MPa and shear stress of 166MPa in the
vertical direction. The compressive stress in the horizontal direction is 176MPa with a shear
stress of 115MPa.
a. Sketch the state of stress on this element.
b. Determine the maximum and minimum normal and shear stresses and their plane of
orientation.
c. If the yield strength of the material is 350MPa, Poison’s ratio is 0.32, and factor of
safety is 5, determine the diameter of the shaft to avoid failure.
d. What will be the difference in the analysis above if there is an additional torsional
load (T) and bending moment (M).
e. Show how you can use any theory of failure to design this shaft.
f. What are the challenges of applying the theories of failure in actual engineering
practice and as a design engineer, how would you deal with these challenges.

Net Present Value Method, Internal Rate of Return Method, and Analysis

The management of Quest Media Inc. is considering two capital investment projects. The estimated net cash flows from each project are as follows:

The radio station requires an investment of $819,990, while the TV station requires an investment of $1,627,350. No residual value is expected from either project.

Required:

1a. Compute the net present value for each project. Use a rate of 10% and the present value of an annuity of $1 in the table above. If required, use the minus sign to indicate a negative net present value. If required, round to the nearest whole dollar.

1b. Compute a present value index for each project. If required, round your answers to two decimal places.

2. Determine the internal rate of return for each project by (a) computing a present value factor for an annuity of $1 and (b) using the present value of an annuity of $1 in the table above. If required, round your present value factor answers to three decimal places and internal rate of return to the nearest whole percent.

3. The net present value, present value index, and internal rate of return all indicate that the   is a better financial opportunity compared to the  , although both investments meet the minimum return criterion of 10%.
