Answer:
The standard deviation is 11 points
Step-by-step explanation:
To calculated the z-score of a value x, we use the following equation:

Where m is the mean, s is the standard deviation and z is the z-score.
If we solve this equation for s, we get:

So, replacing z by 2, m by 153 and x by 175, we get:

Therefore, the standard deviation is 11 points
Answer:
-8
Step-by-step explanation:
if you sub in 8 as the value for y, you get
-4x - 8 = 24
add 8 on both sides to simplify
-4x = 32
divide both sides by -4
x = -8
Answer:
x=-5
Step-by-step explanation:
subtract 45 from left side. 35-45=-10. divide 2 by -10.
