Consider the linear operator of left multiplication by an $m \times m$ matrix A on the space $F^{m \times m} \text { of all } m \times m$ matrices. Determine the trace and the determinant of this operator.

The __________ creates an object in memory and returns a reference to that object. a. = operator b. object allocator c. reference variable d. new operator

A tour operator has three vans, and each can accommodate seven tourists. Suppose 14 people arrive for a city sightseeing tour and the operator will use only two vans. In how many ways can the operator assign the people to the vans?

Suppose that the binary operator + is overloaded as a member function for the class strange. How many parameters does the function operator+ have?

Select the best answer. Consider an experiment to investigate the effectiveness of different insecticides in controlling pests and their impact on the productivity of tomato plants. What is the best reason for randomly assigning treatment levels (spraying or not spraying) to the experimental units (farms)? (a) Random assignment allows researchers to generalize conclusions about the effectiveness of the insecticides to all farms. (b) Random assignment will tend to average out all other uncontrolled factors such as soil fertility so that they are not confounded with the treatment effects. (c) Random assignment eliminates the effects of other variables, like soil fertility. (d) Random assignment eliminates chance variation in the responses. (e) Random assignment helps avoid bias due to the placebo effect.

Let V be a finite-dimensional vector space. What is the minimal polynomial for the identity operator on V? What is the minimal polynomial for the zero operator?
