Answer to Question 1

a
RATIONALE: The proportionality assumption necessary for a linear programming model to be appropriate, means that the contribution to the objective function and the amount of resources used in each constraint are in accordance to the value of each decision variable.

Answer to Question 2

10/121
RATIONALE: The events are independent, so the multiplication law for independent events can be used to calculate the joint probability.

P(red then purple) = P(red)  P(purple) = 2/11  5/11 = 10/121

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
