In any given year, an insurance company believes the following:

-0.6 of drivers are safe.

-0.25 of safe drivers wear seatbelts

-0.10 of unsafe drivers wear seatbelts

-0.10 of safe drivers experience an accident in a year

-0.20 of unsafe drivers experience an accident in a year

-Given a driver experiences an accident, the driver has probability 0.01 they will be taken to the hospital if they were wearing a seatbelt

-Given a driver experiences an accident, the driver has probability 0.2 they will be taken to the hospital if they were not wearing a seatbelt

What is the probability a driver will be taken the hospital this year (as a result of an accident)? Given that a driver wears a seatbelt, what is the probability he/she will be taken to the hospital this year?

A. Look up and report K_f for copper(II), iron(II), and iron(III) with EDTA. Cite your reference(s). (0.2) (I DID THIS ALREADY)

B. What happens to your titration and results if any of those metals are present? Write a balanced chemical equation showing the impact of iron(III) present in the tap water when you are analyzing for calcium. (0.4)

C. What is done to keep iron ions from interfering? Write a balanced chemical equation for this reaction. (0.4)

D. What is done to keep copper ions from interfering? Write a balanced chemical equation for this reaction. (0.4)

Please help!!!! I really want to understand this

Problem 14

: A 75kg ice fisherman is sitting at rest on a frictionless lake. Suddenly, he notices a 15kg trout sliding at 3.0 m/s toward him on the ice. He catches the trout, and both slide

away together.

(a) What is the speed of the fisherman (holding the trout) after the collision?

(b) The fisherman realizes that he and the trout are sliding toward thin ice! He throws the fish

as hard as he can toward the thin ice. During the throw, he exerts a force of 200 N for 0.2

seconds.

(i) What are the final speeds of the trout and the fisherman?

(ii) Will the fisherman fall through the ice? Explain how you know.

The consumer magazine also claims that the cinnamon rolls at STARBUCKS do not weigh at least 8 ounces. A random sample of 25 customers purchasing cinnamon rolls yields the following results: - the sample mean equals 7.87 ounces - it is known from previous studies that the population standard deviation equals 0.25 ounces.

a. Set up a 95% confidence interval for the true mean?

b. What sample size is required if you want to be 99% sure that the sample mean will be within 0.2 ounces of the true mean?

c. Test the hypothesis that the true population mean is less than 8 ounces. Set the type one error equal to 1%.

John was swimming in the river. His swimming velocity was 1.2 m/s due east. The water was running at 0.4 m/s due west. John’s projected area in the water was 0.45 m2. Water density was 1000 kg/m3. The coefficient of drag was 0.2. (a) What was John’s velocity relative to the water? (b) What was the pressure drag force from the water? After a little while, John turned around and now is swimming at 1.2 m/s due west. (c) What is John’s velocity relative to the water now? (d) What is the pressure drag force from the water now? (e) What is the percentage of change in pressure drag force?

Partial Insurance: An individual has $2000 in physical assets, and $600 in cash initially. This person faces the following loss distribution to the wealth. Full insurance is available at $600

The Individual can also buy partial insurance with i. a $200 deductible, or ii. 75% coinsurance, or iii. Upper limit on coverage, with the limit being $1000. The premium on each partial coverage policy is $450. Provide a ranking of the four types of policies for the individual, in terms of preference if the preference function is given by U(FW) = LN(1+FW), where FW is final wealth of the individual.

Suppose a fund has a portfolio with two risky assets; stock and bond. Annual expected return of stock is 0.15 and standard deviation of 0.10 and expected return of bond is 0.08 and standard deviation of 0.07. The correlation-coefficient between stock and bond is 0.2. while t-bill has annual return of 0.03

Draw the opportunity set with 25% increment in bond fund. Also indicate the variance minimizing weight for bond and stock

Draw the optimal CAL line and calculate the sharp ratio

If the investor requires the complete portfolio standard deviation of 5%, how much of his fund to be invested in the risky portfolio (in terms of proportion, how big is y?)

1. Kiwi traders have invested in two securities traded at the Nairobi Stock Exchange (NSE). The security A Possible returns are estimated as 4%, 4.5%, 6%, 8%, 11%, 13%, 15%, 16%, 16.5% and 18%, with probabilities: 0.09, 0.07, 0.1, 0.2, 0.04, 0.03, 0.01, 0.02, 0.21 and 0. 23 respectively. Those of Security Y are estimated as 16%, 14%, 12%, 10%, 8%, 6%, 4%, 4%, 3%, and 2%, with probabilities: 0.08, 0.1, 0.07, 0.25, 0.09, 0.12, 0.03, 0.11, 0.1 and 0.05 respectively.

If Kiwi trader’s portfolio formation is Ksh 300,000, committing equal amounts in each asset, determine the Portfolio risk

Consider a Solow economy with the following production function

F(K,N) = zK^(1/3)N^(2/3)

and parameters d = 0.05, s = 0.2, N0 = 100 and z = 1.0. Suppose K = 300 in period 0 and the

unit period is one year. In contrast to the standard Solow model, we assume that the population

growth rate n is no longer exogenous but rather endogenous and determined by

(1 + n) = N’/N = g(C/N) = (C/N)^3 as it is the case in the Malthusian model.

Question: Find k* the steady state per-capita capital stock, consumption per capita (c*) and output

per capita (y*).

Hooper Chemical Company, a major chemical firm that uses such raw materials as carbon and petroleum as part of its production process, is examining a plastics firm to add to its operations. Before the acquisition, the normal expected outcomes for the firm were as follows:
  

Compute the expected value, standard deviation, and coefficient of variation prior to the acquisition. (Do not round intermediate calculations. Enter your dollar answers in millions rounded to 2 decimal places (e.g., $12,300,000 should be entered as "12.30"). Round the coefficient of variation to 3 decimal places.)
