Nonnegativity constraints ensure that
 a. the problem modeling includes only nonnegative values in the constraints.
  b. the solution to the problem will contain only nonnegative values for the decision variables.
  c. the objective function of the problem always returns maximum quantities.
  d. there are no inequalities in the constraints.

Question 2

A nickel and a dime are tossed. If an event is defined as a single toss of both coins where at least one head appears, what is the complement of that event?

Answer to Question 1

b
RATIONALE: Nonnegativity constraints ensure that the solution to the problem will contain only nonnegative values for the decision variables.

Answer to Question 2

tails-tails

RATIONALE: The event has 3 possible outcomes--heads-heads, tails-heads, and heads-tails. Given an event A, the complement of A is defined to be the event consisting of all outcomes that are not in A. The only outcome not in the event is tails-tails.
