Answer:
The variance is
Step-by-step explanation:
From the question we are told that
The sample size is n = 21
The sum of squares is
Generally the variance is mathematically represented as
substituting values
We can solve this by using the P<span>ythagorean theorem which is below:
Or we can say
</span>
<span>w = widht
h = height
d = diagonal measure
With that said, we know the height is .75 times the width so .75w. We also know d = 34, which is our diagonal measure.
w = don't know yet but need to find
h = .75w
d = 34
Now lets plugin the information we know into our equation
</span>
Now lets to the math
Combine like terms
Divide both sides of the equal sign by 1.5625
Now take the square root on both sides of the equal sign
So the width is 27.2
We can check this by putting 27.2 back into our original equation
