Answer:
Jen needs approximately 8 tiles to cover the kitchen floor
Step-by-step explanation:
What we want to calculate here is the number of tiles needed to cover the kitchen floor.
The first thing we need to do here is to calculate the area of the kitchen floor.
Mathematically, that would be the product of the length of the kitchen floor and the length of the width.
That is; 4 5/6 * 5 = 29/6 * 5 = 145/6 m^2
Now, to calculate the number of tiles needed, we only need to divide the area of the kitchen floor by the area of the individual tiles
Mathematically, that would be;
145/6 ÷ 3 = 145/6 * 1/3 = 145/18 = 8.05556
This is approximately 8 tiles

Complete Question
Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 143 millimetres, and a standard deviation of 5. If a random sample of 47 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by more than 0.2 millimetres? Round your answer to four decimal places.
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 47
The mean diameter is 
The standard deviation is 
Generally the standard error of the mean is mathematically represented as

=> 
=> 
Generally the probability that the sample mean will differ from the population mean by more than 0.2 milli meters is mathematically represented as

=> 
=> 
From the z table the area under the normal curve to the left corresponding to -2.742 is

From the z table the area under the normal curve to the right corresponding to 2.742 is
P(Z > 0.2742) = 0.39197
So
