Answer:
Cost of new carpet per square foot should be less than or equal to $3.54.
Step-by-step explanation:
Given:
Money have to buy carpet =
dimension of game room is 20 feet by 12 feet
So we can say length l = 20 feet
and width w = 12 feet
let be the cost per square foot for new carpet.
Assuming game room to be rectangular in shape we will find the area of it.
Area of room =
Total area cost per square feet ≤ Total money we have
Hence,
Hence Cost of new carpet per square foot should be less than or equal to $3.54.

Step-by-step explanation:
The standard deviation formula is as follows:
where sum means "sum of", x is a value of a data set, m is the mean of the data set, and N is the number of data.
The standard deviation formula may seem confusing, but it will make sense after we break it down. In subsequent sections we will explain an interactive example, step by step. Here's a quick preview of the steps we're about to follow:
Step 1: Calculate the mean with the data from the graph.
Step 2: Calculate the square of the subtraction between the mean and each data (that is, each x).
Step 3: add the values that resulted from step 2.
Step 4: divide by the number of data.
Step 5: take out the square root.
And in this way you can obtain the standard deviation
