2. Suppose that in Example 2.27, 400 units of food A, 500 units of B, and 600 units of C are placed in the test tube each day and the data on daily food consumption by the bacteria (in units per day) are as shown in Table 2.7.

A small market orders copies of a certain magazine for its magazine rack each week. Let X = demand for the magazine, with pmf x 1 2 3 4 5 6 p(x) 1/5 2/15 3/15 4/15 3/15 2/15 Suppose the store owner actually pays $2.00 for each copy of the magazine and the price to customers is $4.00.If magazines left at the end of the week have no salvage value, is it better to order three or four copies of the magazine? [Hint: For both three and four copies ordered, express net revenue as a function of demand X, and then compute the expected revenue.]

Couturereleases a statement to their investors saying that currently they have 50 stores with a total revenueof$7,500,000 and expect to increase the number of stores by about 2 stores per month and increasetotal revenue by about$250,000 per month. What does this statement imply about the current rateof change of the average revenue per store per month?

A store manager observes that the morale of employees in her supermarket is low. She thinks that if their working conditions are improved, pay scales rose, and the vacation benefits made more attractive, the morale will be boosted. She doubts, however, if an increase in pay scales would raise the morale of all employees. Her conjecture is that those who have supplemental incomes will just not be “turned on” by higher pay, and only those without side incomes will be happy with increased pay, with a resultant boost in morale Based on the scenario presented, answer the following questions: A) Identify the Independent, Dependent, Moderating, and Mediating Variables. Also provide justification for your choice. B) Create a schematic diagram (i.e., conceptual framework) that depicts the relationships among the variables. C) Based on the above conceptual framework develops at least four alternate hypotheses.
John is a manager at a small English Bakery that sells gooseberry pies. Currently, each of his three employees, agent 1, agent 2 and agent 3, work independently on full commission. Assume to begin with that individual effort is observable, and that total output is given by Q = 10(E1 + E2 + E2). Agents are paid a salary of a + Qi (where Q1 = 10 E1 = output from agent 1; Q2 = 10E2 = output from agent 2 = 10E2 and so on). Each agent has an alternative utility level of 10 units, and the cost of effort C(E) = E2. Answer the following questions.a) Given this compensation scheme, what is the (privately) optimal amount of effort for agent 1?b) How many pies does she make?c) What must the fixed portion of agent 1’s income (a) be for her utility on this job to exactly equal 10?d) What is agent 1’s total income in the above situation?e) Check to see that agent 1’s utility level is in fact 10 when she gets this total income and chooses her effort optimally.f) What is the profit for the firm that…
Refer to Exercise 12 in Section 3.2. Assume that τ0 = 50 ± 1 MPa, w = 1.2 ± 0.1 mm, and k= 0.29 ± 0.05 mm−1.a) Estimate τ, and find the uncertainty in the estimate.b) Which would provide the greatest reduction in the uncertainty in τ: reducing the uncertainty in τ0 to 0.1 MPa, reducing the uncertainty in w to 0.01 mm, or reducing the uncertainty in k to 0.025 mm−1?c) A new, somewhat more expensive process would allow both τ0 and w to be measured with negligible uncertainty. Is it worthwhile to implement the process? Explain.
Prove Proposition 17.7. In particular, show that if n ∗[K], then there exists a profitable deviation for a financial intermediary to offer securities for a previously unavailable sector and make positive profits, and that if n ∗[K], feasibility is violated. Proposition 17.7 Suppose that Q ≥ (2 − γ )q. Then given K(t), there exists a unique time t equilibrium where all sectors j ≤ n∗(t) = n∗[K(t)] are open and those j >n ∗[K(t)]are shut, where
