A box contains 5 fair coins, 4 coins that land heads with probability 1/3 , and 1 coin that lands heads with probability 1/4 . A coin is taken from the box at random and flipped repeatedly until it has landed heads three times. Let X be the number of times that the coin is flipped and Y be the probability that the coin lands heads.

(a) Find the random variables E(X|Y ) and var(X|Y ) in terms of Y .

(b) Compute E(X).

(c) Compute var(X).

1)Two parallel uniformly charged ring are placed in 4 meter distance. The charge of one of them is 2c and the other one is -3c.

find the zero point position of the Electric field.

2) Two parallel uniformly charged ring are placed in 4 meter distance. The charge of one of them is 2c and the other one is +3c.

find the zero point position of the Electric field

3) A rod with length "l" is lied along x-axis. The charge density of the rod is "a". Calculate the potential of the rod for a the point p on x-axis.

4) A rod with length "l" is lied along x-axis. The charge density of the rod is "a". Calculate the Electric field of the rod for a point p on x-axis.

5) Using the Gausses law find the electric field of a uniformly charged non conducting cylinder with length L and total charge Q:

a)Inside of it

b)out side of it

Using the yen per dollar exchange rate of 120yen/€1 and the 6 months $libor is 4% per annum and the 6 month Yen libor is 7% per annum

You must calculate a 6-month forward rate.

Show how CIP represents an arbitrage concept.

Quantitative Problem 1: You plan to deposit $2,500 per year for 4 years into a money market account with an annual return of 3%. You plan to make your first deposit one year from today.

1. What amount will be in your account at the end of 4 years? Do not round intermediate calculations. Round your answer to the nearest cent.

   $  

2. Assume that your deposits will begin today. What amount will be in your account after 4 years? Do not round intermediate calculations. Round your answer to the nearest cent.

   $  

Quantitative Problem 2: You and your wife are making plans for retirement. You plan on living 25 years after you retire and would like to have $85,000 annually on which to live. Your first withdrawal will be made one year after you retire and you anticipate that your retirement account will earn 12% annually.

1. What amount do you need in your retirement account the day you retire? Do not round intermediate calculations. Round your answer to the nearest cent.

   $  

2. Assume that your first withdrawal will be made the day you retire. Under this assumption, what amount do you now need in your retirement account the day you retire? Do not round intermediate calculations. Round your answer to the nearest cent.

Assume that you need a new car for exactly 4 years.   
You can either
1) lease the car for 4 years
2) purchase the car with a four-year loan and sell it after 4 years.

The dealer has a leasing arrangement where you pay $4,400 today and $580 per month for the next four years.

If you purchase the car, you will pay it off in monthly payments over the four years at a stated interest rate of 12 percent, paid monthly.   

In other words, your interest rate will be 1% per month.

The car you wish to buy costs $35,000. You believe that you will be able to sell the car for $15,000 in four years.

Should you buy or lease the car?   

Please show work.

Principles of Finance II WEEK 4: Discussion Prompt #1 Dividend policy is the set of guidelines a company uses to decide how much of its earnings it will pay out to shareholders. There are three main approaches to dividends: residual, stability or a hybrid of the two. For this discussion, research a publicly traded company that you are interested in or would like to know more about. State what type of dividend policy they currently use. In addition, explain whether you would invest in this company knowing how they pay out dividends.

4. You are managing a bond portfolio of $1 million. Your target duration is 10 years, and you can invest in two bonds, a zero-coupon bond with maturity of five years and a zero-coupon bond with maturity of 15 years, each currently yielding 5%.

(1) What are your weights in these two zero-coupon bonds to have the target duration?

(2) How will these factions change next year if the target duration is still ten years? .

4-1. As a third-year medical student working in the hospital, you are treating a young boy, Jacob, and a young girl, Kristen, who have had chronic ear infections by pyogenic bacteria. Blood work shows that they both have elevated levels of IgM.

(a) What two B cell deficiencies could explain these observations? (do not use abbreviations)

(b) Which patient is more likely (or less likely) to have one type of those deficiencies than the other type and why?

(c) How can you test to determine which of the two possible B cell deficiencies they might have?

(d) Of the two deficiencies named in (b), which one would cause susceptibility to opportunistic infections like Pneumocystis jiroveci and why?

Explain answers in through details.

1. Describe what malpractice is and the 4 elements required to determine whether negligence has occurred. What positive actions could you do as a supervisor to help prevent negligence?

2. Describe one personnel-related regulation. How does this regulation protect employee rights?
