The width of a rectangle is 4n - 1.5 feet and the length is 1.5n + 4 feet. Find the perimeter of the rectangle. The perimeter of the rectangle is feet.
(Simplify your answer. Use integers or decinals for any numbers in the expression.)

Answers

Answer:

11n + 5

Step-by-step explanation:

First, what is the perimeter of a rectangle referring to? It's referring to the outside surrounding the rectangle. You just need to know that the formula for a rectangular perimeter is:

2(L+W) (W = width, L = length)

We are given width: 4n - 1.5We are given length: 1.5n + 4

Now substitute those values for the formula.

2 (4n-1.5 + 1.5n + 4)2 (5.5n + 2.5)11n + 5

The owner of a hair salon franchise in the city asked all of her stylists to report how many new clients they serviced within the last year. The list of new clients serviced is shown below.

Number of New Clients Serviced over the Past Year: 59, 32, 37, 53, 10, 12, 57, 50, 48, 50, 61, 37, 35, 44, 49, 55, 59, 62, 43, 48, 59, 61, 64, 37, 18, 11, 44, 50, 57, 63, 47, 27

The salon owner used this list to create a histogram.

Answers

Answer:

It's 55-59 and 60-64

Step-by-step explanation:

The inaccuracy in the histogram was discovered by the owner would be:

55-59

60-64

Data Table

The inaccuracy in the number of new clients due to the inapt portrayal of the data between intervals 55-59 and between 60 and 64.

They show the number of new clients as 5 and 6 in these intervals which is incorrect and hence, the histogram becomes wrong.

The actual frequency in these intervals is quite lesser as provided by the data and hence, the shown data is invalid.

Thus, the above responses are correct.
