Answer:
D. 14.32
Step-by-step explanation:
The formula for standard deviation is:

The mean μ is 33.
The (x minus μ) squared are 361, 49, 49, 361 respectively.
So that the SD = 
Answer:
z = 18
x = 26 and y = 16
Step-by-step explanation:
Given:


Rewrite
to make
the subject:

Substitute this into
:

Cross multiply:




Substitute found value of x into
and solve for y:


Substitute found value of y into
and solve for z:

W= width
l= length= 4w
Area= lw
16 square yards= lw
substitute l=4w for l
16= (4w)(w)
16= 4w^2
divide both sides by 4
4= w^2
take the square root of 4
2 yards= w
LENGTH
l=4w
l=4(2)
l=8 yards
CHECK:
16= (8)(2)
16= 16
ANSWER: The length is 8 yards and the width is 2 yards.
Hope this helps! :)
