The area of a square relates to its side length as Area = Side Length × Side Length. To estimate a side length, knowing $4/sq ft cost and $600 spent, Side Length ≈ 12 feet.
The area of a square is related to its side length by the formula:
Area = Side Length × Side Length
or Area = Side Length²
To estimate the length of a side of a square,
use the given information that the designer paid $4 per square foot for flooring and spent $600 on the flooring.
The cost of the flooring is directly proportional to its area, which is determined by the square of the side length.
Let's set up an equation using the cost and area:
Cost of flooring = Cost per square foot × Area
$600 = $4/sq ft × Side Length²
Solving for Side Length²
Side Length² = $600 / $4/sq ft
Side Length² = 150 sq ft
Taking the square root of both sides to find the side length:
Side Length ≈ √150
Side Length ≈ 12.25 feet
Rounded to the nearest foot, the side length of the room is approximately 12 feet.
Therefore, the estimated length of a side of the room is about 12 feet.

Answer:
a)
b) If the distribution is normal then the sampling distribution would be bell shaped and normal
c)
And we can use the z score formula given by:
And replacing we got:
And then we can find the probability using the complement rule and the normal standard distribution or excel and we got:
Step-by-step explanation:
For this case we have the following info:
represent the sample size
the sample mean
the standard deviation
Part a
If we assume that the distirbution is bell shaped then we can find the parameters like this:
Part b
If the distribution is normal then the sampling distribution would be bell shaped and normal
Part c
We want this probability:
And we can use the z score formula given by:
And replacing we got:
And then we can find the probability using the complement rule and the normal standard distribution or excel and we got:
