Answer:

Step-by-step explanation:
Let, the length of the rectangle be 'L'
and, width of the rectangle be 'W'
length=2*Width+3

Area of the rectangle= 90 square feet
Area of a rectangle = Length*Width

Using Factorization Method to solve quadratic equation:

Taking common from the equation:

OR

The Width cannot be negative, therefore Width(W)=12 feet


Answer:
A sample of 1068 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
At 95% confidence, how large a sample should be taken to obtain a margin of error of 0.03 for the estimation of a population proportion?
We need a sample of n.
n is found when M = 0.03.
We have no prior estimate of
, so we use the worst case scenario, which is 
Then






Rounding up
A sample of 1068 is needed.
