Answer:
Width = 40 meters
Length = 167 meters
Step-by-step explanation:
Let
Width of the pool = x meters
Then
Length of the pool = 4x + 7 meters
and
Perimeter 
meters
Hence,
This is true since both legs are congruent, both medians are congruent
The easiest way is to plug x=-4, y=-1 in the equation to see which one works.
8(-4)-9(-1)=-23
B is correct.
Answer: 1.18
Step-by-step explanation:
Z = (x - mean) / standard deviation
Z = (85 - 71.4) / 11.5
Z = 13.6 / 11.5 = 1.18
Answer: 15
