Question 1 An electronic component manufacturer has two facilities producing a range of resistors. Facility 1 costs €2000 per day to operate. Facility 2 costs €2500 per day to operate. The production capacities per day are as follows: Facility 1 Facility 2 Orders 25,000 Resistors 1% tolerance: 400 300 Resistors 5% tolerance 300 400 27,000 Resistors 10% tolerance 200 500 30,000 How many days should the manufacturer operate each facility in order to minimise its costs and still produce sufficient resistors to meet its orders? a. Formulate the problem as a linear programming model (hint: let X1 represent the number of days that Facility 1 should operate and X2 represent the number of days that Facility 2 should operate). b. Solve the problem using graphical linear programming (corner point) techniques. Question 2 Solve question 1 above using Excel. The graph and minimum cost result should automatically update if any of the constraints or objective function change.

QUESTION 13 (Please use at least four significant figures in your calculations.) $60 S-curve Turntables $160 Hullabaloo Records $40 $260 S-Curve Turntables manufactures turntables, and sells them through Hullabaloo Records, a chain of specialty record stores. For a model year, they will manufacture their newest model of turntable, called "Orbitz", which will be sold through the record stores. It costs $60 for S- Curve to manufacture the turntables, which it then sells to Hullabaloo for $160. Hullabaloo Records then sells the turntables at retail for $260. Whatever doesn't sell gets put on clearance for $40. Demand for the turntable is expected to be normally distributed with a mean of 1833 and a standard deviation of 1092. What is the optimal order amount that will maximize the SUPPLY CHAIN'S expected profit?

REQUIRED: Based on the above situation, conduct an HR plan for Leeds Institute of Management Studies which will ensure the success and achievement of its objectives.

Question 4 Listen Your Algebra 2 teacher collected data on the number of days each student was absent during a semester and their score, in percent, on the semester exam. The linear regression equation that models the data is ŷ=97.769-3.828x where x represents the number of days absent and y represents the exam score, in percent. The correlation coefficient is r=-0.707 and the coefficient of determination is =0.500. What are the appropriate interpretations of the slope, y-intercept, correlation coefficient, and coefficient of determination? **HINT** Slope: -3.828 y-intercept: 97.769 Correlation coefficient: r = -0.707 The rate the predicted semester exam score decreases for every stu- dent absence. The predicted % score a student will achieve based on having zero absences in a semester. a. correlation coefficient b. y-intercept c. slope The relationship be- tween the number of days a student was ab- sent and their corre- sponding exam score.

QUESTION 7 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. Daytime Evening Percentages 25% Wife 25% 30% Husband 15% 25% Single male 10% Single female 15% 15% None 35% 5% What is the objective function of this linear programming problem? O a. To minimize the number of calls Ob. How many daytime and evening calls to make. OC. To minimize the amount of money to spend on the calls. Od. How many husbands, wifes, single males and single females to call.
