A marketing research professor is conducting a telephone survey and needs to contact at least 160 wives, 140 husbands, 110 single adult males, and 120 single adult females. It costs $2 to make a daytime call and $4 (because of higher labor costs) to make an evening call. The table shown below lists the expected results. For example, 10% of all daytime calls are answered by a single male, and 15% of all evening calls are answered by a single female. Because of a limited staff, at most half of all phone calls can be evening calls. Determine how to minimize the cost of completing the survey

Develop a Report for the following

1) State the decision variables and constraints in this problem.

The following data was collected to explore how the number of square feet in a house, the number of bedrooms, and the age of the house affect the selling price of the house. The dependent variable is the selling price of the house, the first independent variable (x1x1) is the square footage, the second independent variable (x2x2) is the number of bedrooms, and the third independent variable (x3x3) is the age of the house.

Square Feet   Number of Bedrooms   Age   Selling Price
2750 5 14 296600
2696 5 11 294400
2523 4 7 281400
2057    4 7 240600
1797 4 5 208600

a. Assuming that the expectations hypothesis is valid, compute the price of the four-year bond shown below at the end of (i) the first year; (ii) the second year; (iii) the third year; (iv) the fourth year. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

b. What is the rate of return of the bond in years 1, 2, 3, and 4? Conclude that the expected return equals the forward rate for each year. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

Consider the following linear programming problem

Maximize 6x1 + 4x2 + 5x3

Subject to:

2x1 + 3x2 + x3 ≥ 30

2x1 + x2 + x3 ≤ 50

4x1 + 2x2 + 3x3 ≤ 120

x1, x2, x3 ≥ 0

a) Find the optimal solution by using simplex method

b) Find the dual price for the first constraint.

c) Find the dual price for the second constraint.

d) Find the dual price for the third constraint.

e) Suppose the right-hand side of the third constraint is increased from 120 to 125. Find the new optimal

solution and its value.

f) Suppose the right-hand side of the third constraint is decreased from 120 to 110. Find the new optimal

solution and its value.

With celebrity​ bonds, celebrities raise money by issuing bonds to investors. The royalties from sales of the music are used to pay interest and principal on the bonds. In April of​ 2009, EMI announced that it intended to securitize its back catalogue with the help of the Bank of Scotland. The bond was issued with a coupon rate of 6.7​% and will mature on this day 38 years from now. The yield on the bond issue is currently 6.4%. At what price should this bond trade​ today, assuming a face value of $1,000 and annual​ coupons?

What is the percentage change in price for a zero coupon bond if the yield changes from 6.5​% to 8.5​%? The bond has a face value of $1,000 and it matures in 8 years. Use the price determined from the first​ yield, 6.5%, as the base in the percentage calculation.

Evaluate the effect of each shock below using first the classical model and second the Keynesian model. For the Classical model, include graphs of the goods market, the labor market, and the money market. For the Keynesian model, include an IS-LM-FE graph, an Aggregate Supply – Aggregate Demand graph, and a graph of labor market equilibrium with efficiency wages. For the Keynesian model, include short-run effects, while the price is constant, and long run effects after the price has fully adjusted.

1. There is a permanent increase in the money supply.
2. There is an increase in expected future productivity (the z in the production function).
3. There is an increase in government spending financed by an increase in expected future taxes.
4. There is an increase in the price of oil which reduces total factor productivity (z).

Calculate the concentration of the standardized thiosulfate solution.

The following are the steps and the concentration of my KIO₃ was 0.0114 and the weighed mass of Na₂S₂O₃ was 1.719 g

Weigh about 1.7 g Na₂S₂O₃  5H₂O, and transfer it to a 4 oz glass storage bottle. Add 100 mL (graduated cylinder) of room-temperature DI water, which has beenbubbled extensively with nitrogen, and which contains 100 mg /liter Na₂CO₃. Mix

thoroughly and add 1 drop of chloroform to prevent bacterial growth.

2) For the standardization, pipet 5 mL of the KIO₃ solution into each of three 125 mL Erlenmeyer flasks.  From this point treat each flask separately until the titration isfinished.  Make the calculation to estimate your approximate endpoint volume.

3) Add 0.5 g of solid KI and 2.5 mL of 0.5 M H₂SO₄ to the first flask, and immediately

begin titrating with the Na₂S₂O₃ solution.

THE VOLUME OF THIOSULFATE USED UP WAS 5.09 mL

A box contains 500 envelopes, of which 75 contain $100 in cash, 150 contain $25, and 275 contain $10. An envelope may be purchased for $25. What is the sample space for the different amounts of money? Assign probabilities to the sample points and then find the probability that the first envelope purchased contains less than $100.

Question 2
Suppose that in a senior college class of 500 students it is found that 210 smoke, 258 drink alcoholic beverages, 216 eat between meals, 122 smoke and drink alcoholic beverages, 83 eat between meals and drink alcoholic beverages, 97 smoke and eat between meals, and 52 engage in all three of these bad health practices.
If a member of this senior class is selected at random, find the probability that the student
(a) smokes but does not drink alcoholic beverages;
(b) eats between meals and drinks alcoholic beverages but does not smoke;
(c) neither smokes nor eats between meals.
