The current stock price for a company is $38 per share, and there are 8 million shares outstanding. The beta for this firms stock is 0.8, the risk-free rate is 4.3, and the expected market risk premium is 6.2%. This firm also has 230,000 bonds outstanding, which pay interest semiannually. These bonds have a coupon interest rate of 7%, 28 years to maturity, a face value of $1,000, and an annual yield to maturity of 8%. If the corporate tax rate is 35%, what is the Weighted Average Cost of Capital (WACC) for this firm? (Answer to the nearest hundredth of a percent, but do not use a percent sign).

A car is traveling up a 1.5% grade at 65 mi/hr on good, wet pavement. The driver brakes to try to avoid hitting a cone on the road that is 300 ft ahead. The driver’s reaction time is 1.5 second. When the driver first applies the brakes, a software flaw causes the braking efficiency to lower to 0.8 for 100 ft. After the initial 100 ft, the braking efficiency returns to 1.0. How fast will the driver be going when the cone on the road is hit if the coefficient of rolling resistance is constant at 0.015? (Assume minimum theoretical stopping distance and ignore aerodynamic resistance.)

An economy has full-employment output of 1500. Suppose desired consumption and desired investment are
?? = 125 + 0.75(? − ?) − 400?
?? = 200 − 100?
G is the level of government purchases, and T=100

Money demand is
?? ?
= 0.8? − 2000(? + ??)
where the expected rate of inflation, ??, is 0.05. The nominal supply of money M = 2000.

2. Asset market equilibrium and the LM curve.

i) Derive the LM curve when the price level is equal to the solution in part (h) [Hint: Use the price level from the part (2-h) to get the real money supply]

Solution in part H is P = $2

I ran some test about something truly exciting and found that for Group A, the sample meanis 8.5, the standard deviationis 0.6, for n = 12. For Group B, the sample meanis 7.7, the standard deviationis 0.8, and n = 15. Use these values (which you will need to manipulate to suit your needs!) for #1-3. Yes, this is all the info you need!

1. Calculate the effect size using Cohen’s d.

2. Calculate the amount of variance accounted for using r².

3. Construct a 95% confidence interval to estimate the true difference between the groups. Is there one?

The demand for Greta’s Grinders can be characterized by the following point elasticities: price elasticity = -0.8, cross-price elasticity with Melvin’s Mashers = -2, and income elasticity = 1.2. Which of the following statements is false?

1. A price increase for Greta Grinders will decrease both the number of units demanded and the total revenue Gail gets.
2. The cross-price elasticity indicates that a 4% increase in the price of Melvin’s Mashers will cause an 8% increase in quantity demanded of Greta Grinders.
3. An 8% price reduction for Greta Grinders would be necessary to overcome the effects of a 4% decline in income.
4. All the above statements are false.  

A high grade semi-anthracite coal has a complete analysis of 85.86% C, 4.44% H, 2.7% O, 1.2% N, 5% ash and 0.8% S. Analysis of the Residue shows 58% C and 42% ash. Air is
supplied dry at 30°C and 750mmHg. Partial orsat analysis of the stack gas (400°C, 755mmHg) shows 8.05% CO2, 2.42% CO and 2.9%H2.Assume the S and N gasified burns to SO2 and NO respectively. Calculate
a. % excess O2
b. Complete orsat analysis of stack gas
c. m3 stack gas/ m3 air

You want to evaluate three mutual funds using the Jensen measure for performance evaluation. The risk-free return during the sample period is 6%, and the average return on the market portfolio is 18%. The average returns, standard deviations, and betas for the three funds are given below.

The fund with the highest Jensen measure is

Multiple Choice

• Fund A.

• Fund B.

• Fund C.

• Funds A and B (tied for highest).

• Funds A and C (tied for highest).

10 kg of gaseous oxygen is compressed in a piston-cylinder device from an initial state of 0.8 m^3/kg, 25 C to a final state of 0.1 m^3/kg, 287 C, with all heat transfer taking place with the surroundings at 25 C. If the process is reversible, determine:

a) the work done in the process;

b) the overall heat transfer to the oxygen; and

c) the change in entropy of the oxygen and of the surroundings

I struggle a lot with thermodynamics, could you please show all work and if possible state the names of equations used. I will rate! Thank you.

If possible, could you write out the process of these problems? include a drawn normal distribution with shading please.

1. suppose X-N (4, 2) what value of x is 1.5 standard deviations to the left of the mean?
2. Suppose X-N (15,3) between what x values does 68.27% of the data lie? The range of x values is centered at the mean the distribution (i.e., 15)
3. X-N (54,8) find the probability that x>56

4. height and weight are two measurements used to track a child's development. The World Health Organization measures a child's development by comparing the weights of children who are the same height and same gender. In 2009 Weights For All 80cm girls in the reference population at a mean of 10.2 kg and a standard deviation of 0.8 kg. X-N (10.2, 0.8). Weights are normally distributed. calculate the Z scores that correspond to the following weights and interpret them.
a. 11 kg b. 7.9kg c. 12.2 kg

5. Facebook provides a variety of statistics on this website that detailed growth in popularity of the site. On average, 28% of 18 to 35 year olds check their Facebook profile before getting out of bed in the morning. Suppose this percentage follows a normal distribution with standard deviation of 5%. A. find the probability that the percent of 18 to 35 year olds to check Facebook before getting out of bed in the morning is at least 30. B. Find the 95th percentile and express it in a sentence.
