That’s the equation for pi, but the simplified fraction is 22/3 (please mark brainliest)
Answer:
The z-distribution should be used for this problem.
Step-by-step explanation:
The population distribution is assumed to be normal. Which distribution to use?
If we have the standard deviation for the sample, we use the t-distribution.
If we use the standard deviation for the population, we use the z-distribution.
There is a known standard deviation of 2.2 minutes.
This means that 2.2 is the population standard deviation, and thus, the z-distribution should be used for this problem.
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.
