13. During 2020 internationally renowned singer Molly Vanilli is somewhat fed up with singing. A publisher closely related to the music industry offers her to write her memoires from next year onwards and offers her an upfront payment of $1,000,000 now. If she is able to come up with a draft of the first 100 pages in two years time she will receive another payment of $750,000. The book needs to be ready in 4 years. If she succeeds to deliver a publishable manuscript at the end of year 4 she will receive another $2,000,000. In the meantime she cannot give concerts all around the globe which implies an opportunity cost equal to $750,000 per year until and including year 4. Assume a discount rate of 10%. The Net Present Value of this offer comes closest to...

A) $608,000 B) $609,000 C) $610,000 D) $611,000

Ted’s Village has five governmental funds: a General Fund, a Debt Service Fund, and three special revenue fund. IT has no proprietary funds. The following information is available at December 31, 2019 for each of the funds. First, determine which of the funds are major funds. Then, prepare a balanace sheet in the appropriate format, showing the major funds, a total for the nonmajor funds, and a total for all government funds

A blind taste test is conducted to determine which of two​ colas, Brand A or Brand​ B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola​ first, followed by the other​ cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 54 of 100 individuals prefer Brand A. Complete parts a through c. ​(a) Conduct a hypothesis test​ (preferably using​ technology) Upper H 0​: p equals p 0 versus Upper H 1​: pnot equalsp 0 for p 0equals0.43​, 0.44​, 0.45​, ​..., 0.63​, 0.64​, 0.65 at the alphaequals0.05 level of significance. For which values of p 0 do you not reject the null​ hypothesis? What do each of the values of p 0 ​represent? Do not reject the null hypothesis for the values of p 0 between nothing and nothing​, inclusively.

A firm has debt with a face value of $100. Its projects will pay a safe $80 tomorrow. Managers care only about shareholders. A new quickie project comes along that costs $20, earns either $10 or $40 with equal probabilities, and does so by tomorrow. Assume that the time value of money is 0

     1. Is this a positive-NPV project?

    2. If the new project can only be financed with a new equity issue, would the shareholders vote for this? Would the creditors?

     3. Assume the existing bond contract was written in a way that allows the new projects to be financed with first collateral (superseniority with respect to the existing creditors). New creditors can collect $20 from what the existing projects will surely pay. Would the existing creditors be better off?

4. What is the better arrangement from a firm-value perspective?

Please select ONE of the questions below to answer. Use GCU style (no first-person, no contractions, no quotes). Support your response with references from course articles or text readings. Every student’s response is expected to have examples and demonstrate understanding of chemistry.

A regenerative gas-turbine power plant with two stages of compression and two stages of expansion operates on a Brayton cycle with a pressure ratio across the two-stage compressor of 12. Air enters the first stage of the compressor at 100 kPa and 300 K. At the intercooler exit, the temperature is 300 K. In both turbine stages, air enters at 1400 K. The total heat transfer rate to the air in both combustors is 5,000 kW. The regenerator has an efficiency of 70%, both compressor stages have an isentropic efficiency of 75%, and both turbine stages have an isentropic efficiency of 80%. The pressure in the intercooler and reheater is 600 kPa. Using an Air Standard Analysis, find the following

(a) Thermal Efficiency in Percentage
(b) net work output
(c) mass flow rate
(d) Intercooler/Reheater pressure that maximizes the cycle's thermal efficiency
(e) Max Work output

A management company must first decide whether to undertake a market research survey. If
the market research study is conducted, the outcome will either be favorable (F) or unfavorable
(U). Assume there are only two decision alternatives, D1 and D2, and two states of nature, S1
and S2. The payoff table showing profit is as follows:

a) Using the following probabilities, what is the optimal decision strategy?
P(F) = 0.56 P(S1/F) = 0.57 P(S1/U) = 0.18 P(S1) = 0.40
P(U) = 0.44 P(S2/F) = 0.43 P(S2/U) = 0.82 P(S2) = 0.60
b) Find the Efficiency of this market research. What would be your recommendation?
c) How much will this company be willing to pay for this market research?
