The reason for making the measurement three times instead of just once was probably to: A) completely eliminate measurement error. B) increase reliability. C) decrease bias. D) eliminate confounding.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

the expected value of the random variable : 0, 1 and 2
