Hugo scores an average of 28 points per basketball game, and his points per basketball game are normally distributed. Suppose Hugo scores 14 points in a game, and this value has a z-score of −2. What is the standard deviation?

b is the final answer! : )

b

step-by-step explanation:

d. all of the above

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
