Answer:

a. What is the average annual​ return?

average annual return (mean) = (-4.5% + 28.1% + 12.2% + 3.7%) / 4 = 9.875%

b. What is the variance of the​ stock's returns?

variance = [(-4.5% - 9.875%)² + (28.1% - 9.875%)² + (12.2% - 9.875%)²) + (3.7% - 9.875%)²] / 4 = (206.64 + 332.15 + 5.41 + 38.13) / 4 = 582.33 / 4 = 145.5825

c. What is the standard deviation of the​ stock's returns?

standard deviation = √145.5825 = 12.06%

Answer:

Objective function:

Maximize Z: 30P1 + 25P2 + 28P3

Subject to:   2.00P1 + 1.50P2 + 3.00P3 ≤ 450 (Department A constraint)

                    2.50P1  + 2.00P2 + P3       ≤ 350 (Department B constraint)

                    0.25P1  + 0.25P2 + 0.25P3 ≤ 50  (Department C constraint)

                           P1, P2, P3                       ≥  0 (Non-negativity)

Explanation:

The objective function is formulated from the contribution margin of the three products. For instance, the contribution of Product 1 is $30, the contribution of Product 2 is $25 and the contribution of Product 3 is $28. Thus, the objective function will be 30P1 + 25P2 + 28P3.

The constraints were obtained from the departmental labour hours requirements for each product. For instance, Product 1 requires 2 hours in department A, Product 2 requires 1.50 hours in department A and Product 3 requires 3 hours in Department A. Thus, the constraint will be 2.00P1 + 1.50P2 + 3.00P3.
