To determine the number of trout in a lake, a conservationist catches 112 trout, tags them and returns them to the lake. Later, 82 trout are caught, and 32 of them are found to be tagged. How many trout are in the lake?

• 2624 trout

• 287 trout

• 3584 trout

• 442 trout

A student has grades on three exams of 76, 80, and 72. What must the student earn on a fourth test in order to have an average of at least 80?

• at least 95

• at least 92

• 98 or better

Solve: 4x - 2 > 2(x + 6)

• x > 7

• x > 2

• x < 3

Factor: 3x² - 17x + 10

• (x - 2) (3x - 5)

• prime

• (3x - 2) (x - 5)

• ( 3x - 1) ( x - 10)

Solve for x: 3x²= -21x - 30

• {-15, 2}

• {-5, -2}

• { 6, -5}

• { 15, -2}
