Jordan is 53 inches tall. what is his z-score? jake is 44 inches tall. what is his z-score? jacob is 49 inches tall. what is his z-score. photo below of question!

The following are each student's z-scores

Jordan = 2

Jake = -2.5

Jacob = 0

Step-by-step explanation:

To find each of these, use the formula given in the picture. The x value will be the student's height. The mu (or funny looking m) will be the mean. And the sigma (the o with a line) is the standard deviation.

Jordan

z = (x - m)/o

z = (53 - 49)/2

z = 4/2

z = 2

Jake

z = (x - m)/o

z = (44 - 49)/2

z = -5/2

z = -2.5

Jacob

z = (x - m)/o

z = (49 - 49)/2

z = 0/2

z = 0

The following are each student's z-scores

Jordan = 2

jake = -2.5

Jacob = 0

What is the height of a student whose z-score is 3?

55"

Step-by-step explanation:

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
