the length of a rectangle is 5 inches longer than the width. the perimeter of the rectangle is 60 inches. what is the width of t

Bond [772]

The perimeter is the total of adding all of the side lengths together.

A rectangle has 2 opposite side lengths that are the same/equal to each other. So the perimeter of a rectangle is:

P = L + L + W + W or P = 2L + 2W

[P = perimeter, L = length, W = width]

L = W + 5 [the length is 5 inches longer than the width]

You can substitute (W + 5) for "L" in the equation.

P = 2L + 2W

P = 2(W + 5) + 2W

Since you know the perimeter, you can also plug it in.

60 = 2(W + 5) + 2W Multiply 2 into (W + 5)

60 = 2W + 10 + 2W

60 = 4W + 10 Subtract 10 on both sides

50 = 4W Divide 4 on both sides

12.5 = W

Your width is 12.5 inches, your answer is B

A researcher is interested in knowing the average height of the men in a village. To the researcher, the population of interest

Anna11 [10]

Answer:

The population mean height of men in the village is 5.78 feet.

The sample mean height of men in the village is 7.8 feet.

Step-by-step explanation:

It is provided that the researcher's interest is in knowing the average height of the men in a village.

To the researcher, the population of interest is the men in the village, the relevant population data are the height of men in the village, and the population parameter of interest is the mean height of men.

It is also provided that there are 590 men in the village, and the sum of their heights is 3,410.2 feet.

Compute the average height as follows:

$\bar X_{H}=\frac{3410.2}{590}=5.78\ \text{feet}$

Thus, the population mean height of men in the village is 5.78 feet.

It is given that the researcher measured the heights of 18 village men and calculated the average to estimate the average height of all the village men.

The sample for his estimation is 18 men, the relevant sample data are the heights of the 18 men, and the sample statistic is the sample mean height.

It is also given that the sum of the heights of the 18 village men is 104.4 feet.

Compute the average height of the 18 men as follows:

$\bar x_{H}=\frac{104.4}{18}=7.8\ \text{feet}$

Thus, the sample mean height of men in the village is 7.8 feet.
