Gonna fix some typos with your question:
Carl wants to plant a garden that is 1 1/2 yards long with an area of 3 1/2 square yards. What is the width of the garden?
So with these type of questions, we divide 3 1/2 by 1 1/2, to find the missing length:
3 1/2 ÷ 1 1/2 = 2 1/3.
The width of Carl's garden is 2 1/3 square yards.
For this case we have by definition, that the perimeter of the figure will be given by the sum of its sides, that is:

We add similar terms:

Thus, the correct option is option b. That is, 
Answer:

Answer:
The sampling distribution of x is N(118, 2.5).
Step-by-step explanation:
We have that:
The mean of the population is 
The standard deviation of the population is
.
(a) Choose an SRS of 100 men from this population. What is the sampling distribution of x? (Use the units of mg/dL.)
The mean of the sampling distribution is the same as the mean of the population.
The standard deviation of the sampling distribution is the standard deviation of the population divided by the square root of the sample size. So

This means that the sampling distribution of x is N(118, 2.5).
Answer:

<h2>2.5 is the correct answer .</h2>
