Some NH4I is palced in a reaction placed in a closed container, which is then heated to 400 deg. C. If the total pressure in the container is (7.47x10^2) , mm Hg, what is the value of Kp. Remember to convert the pressures to atm's.

Assume that the DJIA closed at 10,875 one day recently, and the divisor was .12493117.
a. What is the sum of the prices of the 30 stocks in the index, given this information?
b. Assume that one stock in the index, Pfizer, moved $4.40 that day, while the index itself
moved about 105 points (to close at 10,875). What percentage of the total movement in
the DJIA that day was accounted for by the movement in Pfizer?
c. Now assume that one of the 30 stocks had a 2-for-1 stock split that day, declining from
$47.50 to $23.75. What would the new divisor have to be to keep the index unchanged at
10,875?

    (b) How much was the bank's leverage ratio (defined as the equity multiplier) at the end of March 2020?
    (c) In April 2020, the bank's assets decreased by 2%, while the bank's liabilities remained unchanged. What was the percentage change in the bank's capital in April 2020?

2.) Mutually exclusive projects may be ranked differently when higher or lower discount rates are used.

a. True

b. False

13.) The option to abandon a project before the end of its forecasted life may increase its NPV.

a. True

b. False

18.) Porter Climate Control is evaluating a proposal to move some manufacturing operations from an obsolescent plant in Illinois to a new facility in Mexico. The new facility will cost $58 million to open. and is expected to result in savings of $16 million per year for the first five years. At the end of 5 years, Porter will decide either to close the plant in Mexico or to keep it indefinitely. If Porter closes the plant, the building and equipment can be sold for $20,000,000. If the plant is kept, assume that the $16 million turns into a perpetuity. There is a 30% chance the plant will be closed and a 70% chance it will be kept. Compute the expected NPV of the project. Use a discount rate of 12%.

a. $75.32 million

b. ($30.32 million)

c. $56.04 million

d. $114.04 million

*An adult human being at rest produces roughly 0.40 mJ/h of thermal energy through metabolic activity. Use that fact to solve the following problems.
(a)
A college student who weighs 128 pounds put off a major assignment until the day before it was due and worked for eight hours to complete it. If she is modeled as a closed adiabatic system at constant pressure, her heat capacity and molecular weight are approximately the same as that of liquid water, and her temperature was normal when she began to work, what would her temperature have been by the time the assignment was finished?
(b)
Now model the student as an open system and assume that evaporation of perspiration (evaporative cooling) is the only mechanism for heat loss. How much weight would she have lost through evaporation if she maintained a constant body temperature?
(c)
Are either of the models in Parts a and b reasonable? Explain. What is the most likely explanation of what happened to the metabolic energy produced in her body?

Thomson Media is considering some new equipment whose data are shown below. The equipment has a 3 year tax life and would be fully depreciated by the MACRS method over 3 years, but it would have a positive pre-tax salvage value at the end of year 3, when the project would be closed down. Also, additional net operating working capital would be required, but it would be recovered at the end of the project's life. Revenues and other operating costs are expected to be constant over the project's 3 year life. What is the project's total cash flow in year 3? Create a table. DO NOT USE EXCEL

-Net investment in fixed assests = $70,000

- Required net opertaing work capital = $15,000

-Depreciation (MACRS): 33% in year 1

45% in year 2

15% in year 3

7% in year 4

- Earnings before taxes & depreciation = $54,000

- Expected pre-tax salvage value = $6,000

- Tax Rate: 35%

- WACC: 8%

You may need to use the appropriate technology to answer this question.

A market research firm used a sample of individuals to rate the purchase potential of a particular product before and after the individuals saw a new television commercial about the product. The purchase potential ratings were based on a 0 to 10 scale, with higher values indicating a higher purchase potential. The null hypothesis stated that the mean rating "after" would be less than or equal to the mean rating "before." Rejection of this hypothesis would show that the commercial improved the mean purchase potential rating. Use

α = 0.05

and the following data to test the hypothesis and comment on the value of the commercial.

(a) State the null and alternative hypotheses. (Use μ_d = mean rating after − mean rating before.)

H₀: μ_d ≠ 0

H_a: μ_d = 0

H₀: μ_d > 0

H_a: μ_d ≤ 0

H₀: μ_d ≤ 0

H_a: μ_d = 0

H₀: μ_d = 0

H_a: μ_d ≠ 0

H₀: μ_d ≤ 0

H_a: μ_d > 0

(b)Calculate the value of the test statistic. (Round your answer to three decimal places.)

Calculate the p-value. (Round your answer to four decimal places.)

p-value =

(c) State your conclusion.

Do not Reject H₀. There is sufficient evidence to conclude that seeing the commercial improves the mean potential to purchase.

Reject H₀. There is sufficient evidence to conclude that seeing the commercial improves the mean potential to purchase.    

Reject H₀. There is insufficient evidence to conclude that seeing the commercial improves the mean potential to purchase.

Do not reject H₀. There is insufficient evidence to conclude that seeing the commercial improves the mean potential to purchase.
