Question 1

Consider the two assets A and B for which returns (%) under different conditions of economy are given as below.

1. Find the expected return of each asset
2. Find the risk (as measured by standard deviation of return) of each asset
3. If an investor decides to invest $48,000 in stock A and $32,000 in stock B, calculate the expected returns of the investor’s portfolio of stocks A and B.
4. Using the information, calculate the portfolio’s standard deviation if the correlation of the returns between stocks A and B returns is -0.52.

1. You are using 9 different chemicals for this laborartory experiment. For each possible reaction between the 9 chemicals, predict the products and write a balnced, complete molecular equation.

2. Look at the products you predicted for the first question. Create a three column table of a) insoluble precipate formed, b) gas formed, and c) no reaction. Place the reactions in the appropriate column(s).

Dr. McFadden, a surgeon, must decide what mode of treatment to use on Mr. Samuels. There are three modes of treatment: Mode A, B, and C; and three possible states of nature: 1. Treatment succeeds, and patient leads a normal life, 2. Patient survives treatment but is permanently disabled, and 3. Patient fails to survive treatment. The probability of that the patient leads a normal life is 0.4, Disability is 0.4 and Non-survival is 0.2. Dr. McFadden has prepared the decision table below. What mode of treatment maximizes the expected value?

b. Provide examples of two examples of public goods or services from which you personally benefit. Could these goods and services be provided by private markets? Why or why not? (0.6 point)

6. a. Assume that there is a positive relationship between age and height. What does it mean? (0.4 point)

b. If you build a two-dimensional graph between these two variables (age and height), what type of slope will you get? Explain. (0.2 point)

Issue # 2 - A V-belt from a 10 in. Diameter spindle pulley that rotates at 1800 rpm, to a 36 in. Diameter flat pulley. The wheelbase is 40 "and the throat angle is 40o. The friction coefficient between the belt and the grooved pulley is 0.2 and with the flat pulley it is also 0.2. The cross section of the straps is a trapezoid with parallel sides of 1.5 "and 0.75", with a height between them of 1 ". The weight of this belt is 0.04 lbf / in3, and the maximum allowable tension on each belt is 200 lbf. Determine: a) How many straps are needed. b) The Torque applied in the transmission, c) The Transmitted power. Note: Consider locating the center of gravity of the belt cross section in order to correct the actual pulley diameter as the band on the splined pulley is slightly outward.)

1. State and use the average payoff strategy to choose the best decision
2. State and use the aggressive strategy to choose the best decision
3. State and use the conservative strategy to choose the best decision
4. State and use the opportunity loss strategy to make the best decision
5. Suppose the decision maker obtains information that enables the following probabilities assessments: P(s_1) = 0.5; P(s_2) = 0.2; P(s_3) = 0.2; and P (s_4) = 0.1. use the expected value approach to determine the optimal strategy

1) 2A → B + C

Two trials of the above reaction are run. The concentration of A in the second trial is three times that in the first. It is found that the initial rate of the reaction in the second trial is nine times the initial rate in the first trial. This indicates that the reaction is

- zero order in [A]

- first order in [A]

- second order in [A]

- third order in [A]

2)The following reaction is run and the data obtained:

2NO(g) + 2H₂(g) → N₂(g) + 2H₂)(g)

What is the order of the reaction with respect to H₂?

What is the order of the reaction with respect to NO?

4) For the reaction A + B → C the following data is obtained:

After you determine the rate law, what is the value of the rate constant for the reaction using the given units? If you choose to enter your answer in scientific notation you must enter it this way 1.2E-3 for 1.2 x 10^-3.

The Butler-Perkins Company (BPC) must decide between two mutually exclusive projects. Each project has an initial outflow of $6,500 and has an expected life of 3 years. Annual project cash flows begin 1 year after the initial investment and are subject to the following probability distributions:

BPC has decided to evaluate the riskier project at 11% and the less-risky project at 8%.

1. What is each project's expected annual cash flow? Round your answers to the nearest cent.

   Project A:	$
   Project B:	$

   
   Project B's standard deviation (σ_B) is $5,822 and its coefficient of variation (CV_B) is 0.78. What are the values of (σ_A) and (CV_A)? Do not round intermediate calculations. Round your answer for standard deviation to the nearest cent and for coefficient of variation to two decimal places.
