As a measure of intelligence, mice are timed when going through a maze to reach a reward of food. the time (in seconds) required for any mouse is a random variable y with a density function given by f(y) = b y2 , y ≥ b, 0, elsewhere, where b is the minimum possible time needed to traverse the maze. (a) show that f(y) has the properties of a density function.

the answer is c. 23/3

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
