value of y is _____4_______.

Consider an ideal vapor-compression refrigeration cycle using Freon 410A (see . https://www.freon.com/en-/media/files/freon/freon-410a-si-thermodynamic-properties.pdf) The pressure in the evaporator is 10y kPa (That is, if y = 3 the evaporator pressure is 30 kPa). and the temperature at the exit of the condenser is 40^oC. The mass flow in the system is (0.05 + y/200) kg/s.   (That is, if y =3, then the mass flow is 0.0.065 kg/s).

1. Find the enthalpy at the entrance to the compressor.                    h = __________ kJ/kg (+ 3 kJ/kg)

2. Find the enthalpy at the exit of the compressor.                              h = __________ kJ/kg (+ 5kJ/kg)

3. Find the enthalpy at the exit of the condenser.                                h = __________ kJ/kg (+ 3kJ/kg)

4. Find the rate of heat transfer in the evaporator:                              = __________ W (+ 300W)

1. Mr. Meadows Cookie Company makes a variety of chocolate chip cookies in the plant in Albion, Michigan. Based on orders received and forecasts of buy-ing habits, it is estimated that the demand for the next four months is 850, 1,260, 510, and 980, expressed in thousands of cookies. During a 46-day period when there were 120 workers, the company produced 1.7 million cookies. Assume that the number of workdays over the four months are respectively 26, 24, 20, and 16. There are currently 100 workers employed, and there is no starting inventory of cookies.

1. What is the minimum constant workforce required to meet demand over the next four months?
2. Assume that cI = 10 cents per cookie per month, cH = $100, and cF = $200. Evaluate the cost of the plan derived in part (a).
3. Formulate as a linear program. Be sure to define all variables and include the required constraints.
4. Solve for the optimal solution.

Suppose that the cost of hiring workers each period is $100 for each worker until 20 workers are hired, $400 for each worker when between 21 and 50 workers are hired, and $700 for each worker hired beyond 50.

5. Write down the complete linear programming formulation of the revised problem.

Gautam is interested in learning what types of ethical messages are most effective.

He has three conditions, integrity, confidentiality, professional behavio, and

he randomly assigns 20 people to each of these conditions. After each person reads the message, they rate its effectiveness

on a 1-10 scale.He runs a one-way ANOVA and finds the following results:

Condition Mean

Integrity               6

Confidentiality           5

Professional Behavior   9

Source SS df MS F

a)Complete the one-way ANOVA table.

b) Determine the critical F at a=.01

What conclusion should Gautam make?

c) Is it appropriate to calculate a Tukey HSD test for this problem? Why? If it is appropriate, calculate a Tukey HSD test for each of the three possible comparisons between two means. What groups are significantly different from each other at a=.01

Backcountry Adventures is a Colorado-based outdoor travel agent that operates a series of backcountry huts. Currently, the value of the firm is $3.8 million. But profits will depend on the amount of snowfall: If it is good year, the firm will be worth $5.2 million, and if it is a bad year it will be worth $2.5 million. Suppose managers always keep the debt to equity ratio of the firm at 30%, and the debt is riskless.

a. What is the initial amount of debt?
b. Calculate the percentage change in the value of the firm, its equity and its debt once the level of snowfall is revealed, but before the firm adjusts the debt level to achieve its target debt to equity ratio.
c. Calculate the percentage change in the value of outstanding debt once the firm adjusts to its target debt-equity ratio.
d. What does this imply about the riskiness of the firm's tax shields. Explain.

The company maintains a constant 40 percent dividend payout ratio and a constant debt–equity ratio. What is the maximum dollar increase in sales that can be sustained assuming no new equity is issued? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Maximum increase in sales $

Suppose that the objective of a two-variable optimization model is to maximize 20X1 + 13X2, and that we find by graphing that the binding constraints are:

(3) 9X1+3X2≤87 (7) 4X1+6X2≤62

Based on the above, the optimal solution is at X1 = 8, X2 = 5, and OFV = 225.

(a) For the objective function coefficients, find the allowable increase and decrease for each coefficient (based on one-at-a-time changes).

(b) Suppose that the right-hand side of (3) is changed to 87+∆b3. Find expressions for the values of X1, X2, and OFV as a function of ∆b3, and from the latter state the shadow price of this constraint. [Do not worry about the allowable range.]

Background: Judith and Eric Sultan own a business providing HR decision-making expertise to employers across the nation. The name of their business is HRM Analysis Services. Their business is located in Phoenix and has grown exponentially since 2005. Up to this point they have not had their own employees, but instead hired established consultants (often called management analysts) to work on a project-by-project basis.

They want to hire three full-time management analysts to work in three different locations: San Francisco, Philadelphia, and Miami. The analysts would scout out work in their designated regions and manage the contracting and oversight of contractual consultants.

Judith and Eric plan to keep ownership of the company, but want to step away from the day-to-day as soon as the business is working well enough without them.

The focus of this assignment is to assist Judith and Eric with the selection of three Management Analysts by coming up with a weighted formula of important selection factors.
