Scores on Ms. Nash's test have a mean of 64 and a standard deviation of 9. Steve has a score of 52. Convert Steve's score to a z-score. (Round to two decimal places if necessary.)

a. 58.2
b. –1.33
c. 1.33
d. –2

b. –1.33

Step-by-step explanation:

The z-score measures how many standard deviations a score X is above or below the mean.

It is given by the following formula:

In which is the mean and is the standard deviation.

In this problem, we have that:

. We have to find Z

So the correct answer is:

b. –1.33

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

answer: i would say b

step-by-step explanation:

with the way the question is worded, i believe b is the answer
