The following function is probability mass function. -2 -1 0 1 2 1/8 2/8 2/8 2/8 1/8 Determine the mean, , and variance, , of the random variable. Enter the exact answers (as fractions if necessary).

The mean of the random variable is 0.

The variance of the random variable is

Step-by-step explanation:

We are given the following probability distribution:

Mean:

Sum of each value multiplied by its probabilities. So

The mean of the random variable is 0.

Variance:

Sum of the difference squared between each value and the mean, multiplied by its probabilities. So

The variance of the random variable is

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
