A portfolio consists of 50% invested in Stock X and 50% invested in Stock Y. We expect two probable states to occur in the future: boom or normal. The probability of each state and the return of each stock in each state are presented in the table below. State Probability of state Return on Stock X Return on Stock Y Boom 20% 25% 35% Normal 80% 10% 5% What are the expected portfolio return and standard deviation?

Select one: a. 12% and 8.1% b. 12% and 9% c. 14.25% and 10.31% d. 14.25% and 9% e. 18.75% and 12.12%

1. Compound A is three times more soluble in diethyl ether than in water, so its partition coefficient is K = 3, for partitioning of compound A between diethyl ether and water. For a sample of compound A dissolved in 50 mL of water, answer the following questions:

A.) Determine the fraction of A that remains in the water, FsubA, after one extraction with 200 mL of diethyl ether.

B.) Determine FsubA after two extractions, using 100 mL of diethyl ether in each of the extractions.

C.) Determine FsubA after four extractionsm using 50 mL of deithyl ether in each of the extractions.

A clinical trial is conducted to compare an experimental medication to placebo to reduce the symptoms of asthma. Two hundred participants are enrolled in the study and randomized to receive either the experimental medication or placebo. The primary outcome is self-reported reduction of symptoms. The data are recorded as follows.

Is there a difference in change in symptoms by treatment group? Run the appropriate test at a 5% level of significance.

You are considering investing $1,000 in a complete portfolio. The complete portfolio is composed of Treasury bills that pay 5% and a risky portfolio, P, constructed with two risky securities, X and Y. The optimal weights of X and Y in P are 60% and 40%, respectively. X has an expected rate of return of 14%, and Y has an expected rate of return of 10%. The dollar values of your positions in X, Y, and Treasury bills would be _________, __________, and __________, respectively, if you decide to hold a complete portfolio that has an expected return of 8%.

Python(please take a screen shot!):

1. hamming distance: write a function distance that take two bits strings, you can assume each strings only contains 0's and 1's. (Note: the two strings might have the same length or not!)

for example:

hamming('010001001111', '01010100') should return 5(1 bit changed plus 4 bits "lost" from the end). 

2. write a main function that ask user for two file names, open files and read the 1st line of each, and compares them using Hamming Distance. Just assume each of the 1st line only contains 0's and 1's.

The main function may have to do some extra work to remove newline characters or other whitespace from the text read from each file.

(when create two files to test the main function, make sure the file saved as (.txt) !)

Thanks so much !!!

A brilliant young scientist is killed in a plane crash. It is anticipated that he could have earned $430,000 a year for the next 50 years. The attorney for the plaintiff’s estate argues that the lost income should be discounted back to the present at 4 percent. The lawyer for the defendant’s insurance company argues for a discount rate of 9 percent.
What is the difference between the present value of the settlement at 4 percent and 9 percent? Compute each one separately. Use Appendix D for an approximate answer but calculate your final answer using the formula and financial calculator methods. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

PV at 4% =

PV at 9% =

Cane Company manufactures two products called Alpha and Beta that sell for $175 and $135, respectively. Each product uses only one type of raw material that costs $5 per pound. The company has the capacity to annually produce 117,000 units of each product. Its average cost per unit for each product at this level of activity are given below:

The company considers its traceable fixed manufacturing overhead to be avoidable, whereas its common fixed expenses are unavoidable and have been allocated to products based on sales dollars.

6. Assume that Cane normally produces and sells 101,000 Betas per year. What is the financial advantage (disadvantage) of discontinuing the Beta product line?

8. Assume that Cane normally produces and sells 71,000 Betas and 91,000 Alphas per year. If Cane discontinues the Beta product line, its sales representatives could increase sales of Alpha by 11,000 units. What is the financial advantage (disadvantage) of discontinuing the Beta product line?

9. Assume that Cane expects to produce and sell 91,000 Alphas during the current year. A supplier has offered to manufacture and deliver 91,000 Alphas to Cane for a price of $124 per unit. What is the financial advantage (disadvantage) of buying 91,000 units from the supplier instead of making those units?

10. Assume that Cane expects to produce and sell 61,000 Alphas during the current year. A supplier has offered to manufacture and deliver 61,000 Alphas to Cane for a price of $124 per unit. What is the financial advantage (disadvantage) of buying 61,000 units from the supplier instead of making those units?
