‍You are taking a multiple-choice test that awards you one point for a correct answer and penalizes you 0.25 points for an incorrect answer. If you have to make a random guess and there are five possible answers, what is the expected value of guessing? [the expected value of a random variable that can take on two values (x1, x2) with probabilities (p, 1-p) is E(X)= (p*(x1)) + ((1-p)*(x2)). In this case, p represents the chance of getting a correct answer, while x1 and x2 refer to the possible points]. ‍0.5 ‍0.25 ‍-0.25 ‍0
Guy Fieri has purchased a significant plot of land in Northwest Ohio for his newest venture: FlavorTownship. This hub for mind-boggling flavor and entertainment is a strictly for-profit operation. Guy would like to keep Flavor Township open all year-round, but due to Ohio weather the following are the probabilities of when it will be open: |- 30% chance it is open 300 days a year |- 55% chance it is open 325 days a year |- 15% chance it is open 350 days a year Flavor Township will expect to host 14,000 people each day that it is open and expects an average revenue of $45 per visitor. This paradigm-shifting landmark will cost $420,000,000 to start the investment and will require annual costs (food, employees, etc.) of $115,000,000. Every 3 years, Flavor Township will undergo necessary maintenance that will cost $22,000,000. If the expected life of Flavor Township is 15 years and a 16% return is expected, what is the expected NPV of this project?

Answer for (b) & (c) Please Airtight Manufacturing produces plastic cases that utility companies buy to protect electronic components on utility poles from weather damage. (a) The protective case currently used by utility companies has a 0.045 probability of cracking or breaking in any given year. When a protective case cracks or breaks, the utility company incurs a $800 expense to replace the case. What is the expected value of the utility company’s repair costs per protective case? Show your work. (b) Airtight has recently developed a stronger material for its protective case. The use of this stronger material reduces the case’s probability of cracking or breaking, and serves as a differentiating factor for estimating this product’s VTC. Use the product-needs matrix described in the course to classify this differentiating factor. What type of product characteristic is it? What type of customer need does it satisfy? Justify your answers. (c) If this stronger material enables…
1. Suppose the prices of used cars in the market are normally distributed with a mean of $15,000 and a standard deviation of $7,5000. What is the probability of selecting a car from this market and its priced above $20,000.
Find the probabilities for each, using the standard normal distribution
If the farmer uses pesticides he expects a crop of 60,000 bushels; if he does not use pesticides he expects a crop of 50,000 bushels. The cost of pesticides is $30,000 and the other costs associated with planting and harvesting the crop total $450,000. The price of corn at harvest time will either be $9.00 with probability of 0.50 or it will be $11.00 with probability 0.50, so if the farmer decides to sell the crop at harvest, the expected price per bushel that he will receive is $10.00. If the farmer decides to sell the crop at harvest, then: a. He should not use pesticides because not using pesticides ensures greater expected profit. b. He should not use pesticides because not using pesticides ensures lower expected profit. c. He should use pesticides because using pesticides ensures greater expected profit. d. He should use pesticides because using pesticides ensures lower expected profit.
