Discuss your observations regarding the acid/base chemistry of the Mn(IV) dimer, including stoichiometry, reversibility, and temperature effects.

Protonation of [MnIV(salpn)(µ-O)]2omplex gets protonated? Where else could you have protonated the complex

• Dissolve 0.1 mmol (70 mg) of [MnIV(salpn)(O)]2 in 200 mL of methylene chloride. Divide the solution into 4 equal portions. You may want to reserve a small amount of this solution (approx. 10 mL) for color comparison. For each of the following steps, be sure to make careful observations regarding the color of the solution. The best way to do this is to bring a little bit up in a pasteur pipette and use a flashlight (you may use your phone for this purpose) to aid in seeing the color of the solution.

• To one portion, add one equivalent of triflic acid (25 µL of 1.0 M solution in acetonitrile).

• To a second, add two equivalents triflic acid (50 µL of 1.0 M solution).

• Cool the two remaining portions to –78 °C in a dry ice/acetone bath, and add one equivalent triflic acid to one portion and two equivalents to the other. (Keep the flasks covered while cooling to avoid water condensation in the solutions.)

• Add 1 equivalent of triethylamine (7.2 M, so .025 mmol = 3.5 µL: For convenience, dilute 100 µL to 1 mL in acetonitrile and use 35 µL per equivalent) for each equivalent of triflic acid added to each solution above

Given the performance of 3 mutual funds and S&P500 over the past 15 years in table below:

And assuming that current and average of past 15 years risk free rate is 7.96 %, expected market return is 16.35 % and using a market risk premium of 8.39% (16.35 -7.96) for the 15 year period, estimate:

a. Sharpe ratios of all 3 funds and S&P 500. Which fund has the highest risk adjusted performance according to Sharpe measure? Which of the above funds have beaten the market? (15 points)
b. Treynor of all 3 funds and S&P 500. Which fund has the highest risk adjusted performance according to Treynor measure? Which of the above funds have beaten the market? (15 points)
c. Jensen’s alpha for fund 1?(15 points)
d. Which fund is exposed to most nonsystematic risk? (15 points)

Put the answers of a, b, c in the Table by copy/pasting the table below into the answer box:

Melanoma treatment. An experiment evaluated the use of genetically engineered white blood cells in the treatment of patients with melanoma.^y Patients were divided into three cohorts. Patient cohort 1 received genetically engineered lymphocytes that were cultured ex vivo for 19 days. Cohort 2 received cells that were cultured for between 6 and 9 days. Cohort 3 received cells that were generated by a second rapid expansion performing after 8 to 9 days. Cell doubling times were as follows.

Cohort 1               8.7          11.9        10.0

Cohort 2               11.4        1.0          1.3          1.0          2.0          0.6          0.8          0.7          0.9          1.9

Cohort 3               0.9          3.3          1.2          1.1

Either create a file with these data or download the file MORGAN2006.* from the companion website. Most statistical programs require you to enter that data into two columns: one column for the explanatory variable (COHORT) and the other for the response variable (DOUBLING). Your final data table should have 2 columns and 18 rows.

(a)   Calculate the means, standard deviations, and sample sizes of each group. Use the “double the standard deviation” benchmark to assess whether group variances are significantly different. Is there evidence of heteroscedasticity?

(b)   Conduct Levene’s test for unequal variance. Show all hypothesis testing steps. What do you conclude?

Revenue and expense data for the current calendar year for Dawg Electronics Company and for the electronics industry are as follows. Dawg Electronics Company data are expressed in dollars. The electronics industry averages are expressed in percentages.

a. Prepare a common-sized income statement comparing the results of operations for Dawg Electronics Company with the industry average. If required, round percentages to one decimal place.

ONLY NEED QUESTION F!!!

The Ex Nihilo Corporation has a debt-equity ratio of 0.5. Details of the balance sheet are given in Table 3.

Table 3: Ex Nihilo Co’s balance sheet (market values, numbers in millions)

Assets Liabilities

Fixed Investments £18,000

Debt ? Equity ?

The beta of Ex Nihilo Co’s fixed investments is 1.5. The risk-free rate is 3% and the average return on the market index is 7%.

a. What is Ex Nihilo Co’s weighted average cost of capital (WACC)?

b. What are the values of Ex Nihilo Co’s debt and equity?

c. Ex Nihilo Co’s cost of borrowing is 3.5%. What is Ex Nihilo Co’s cost of equity capital?

d. Assuming that Modigliani-Miller irrelevance of borrowing policy holds, what would the cost of Ex Nihilo Co’s equity be if the debt-equity ratio increases to 1.0? You should assume that the increase in borrowing increases the cost of borrowing to 3.6%.

e. Explain the trade-off theory of borrowing.

f. Assume that the debt-equity ratio of Ex Nihilo Co has been raised to 1.0. Modigliani-Miller irrelevance of borrowing does not hold, so the increase in borrowing will increase both the PV of the corporate tax shield of borrowing and the PV of the expected bankruptcy costs. The PV of the tax shield is £0.6bn and the PV of the bankruptcy costs is £0.1bn. The cost of debt capital is 3.6%. Assuming that both the PV of the tax shield and the PV of the bankruptcy costs have a beta of 1.5, what is the new WACC and the new cost of equity capital?

The space shuttle orbits the earth 16 times per day.

m_earth = 5.975 x 10²⁴ kg              r_earth = 6.371 x 10⁶ m          G = 6.67 x 10^-11 N^.m²/kg²

1. How high (in miles) above the earth does it orbit?     Height “h” above the Earth’s surface?
2. What is the acceleration due to gravity at this height? a_Centrip = a_Grav
3. What is the period (in hours) of revolution?   T = ? 1/f           f Þ rev/hr

            w = 16 rev/dy = 16rev/24h = 0.667 rev/h                                          

                                                            = 0.667rev/h(2prad/rev)(1h/3600s) = 1.16x10^-3 rad/s

                        F_Centrip = F_Grav               m_Sa_Centrip = (Gm_Sm_E)/r²

Q: Doris locks Phil in a third floor room. Phil sues Doris for false imprisonment. Which of the following statements is true?

a: Doris would not be liable if Phil could have escaped by traveling two miles through a narrow sewer line that periodically floods with water.

b: In some jurisdictions, Doris would escape liability if Phil slept through the entire period that the door was locked and thus was unaware that he was being detained.

c: Doris would escape liability if she let Phil out of the room after one hour.

d: Even if Phil could have easily escaped through an open window, Doris is still liable. INCORRECT
