Answer: 29.916 minutes
Step-by-step explanation:
Given the following :
Mean of distribution = 17.8 minutes
Standard deviation of distribution = 5.2 minutes
Percentage of customers to give free lube and oil change service should not exceed 1% if the customer waits beyond the guaranteed time ;
Length of guarantee :
Since % of customers should not exceed 1%
Then probability of not being chosen = (1 - 0.01) = 0.99
Using the z table to find the Zscore of 0.99,
Zscore of 0.99 = 2.33
This is 2.33 standard deviations above the mean
(2.33 × standard deviation) + mean value
(2.33 × 5.2 minutes) + 17.8 minutes
12.116 + 17.8
= 29.916 minutes
The value of d in equation Q/R=8/d is 8R/Q.
Given an equation Q/R=8/d.
We are required to find the value of d in the given equation.
Equation is basically the relationship between two or more variables that are expressed in equal to form. The values that we enter is known as domain and the values that we get is known as range. It can be linear equation, quadratic equation, cubic equation.
The equation is :Q/R=8/d
We have to take d in right side of equal to sign and Q,R to the left side of right side of equal to sign.
d=8R/Q
Hence the value of d in equation Q/R=8/d is 8R/Q.

Answer:c
Step-by-step explanation:
It's a scale factor of 3. the way you find out is by counting from the center point to an edge point on the orignal. then do the same on the scales one. now divide the scaled one by the orignal and bam you get the answer
It is important because if you are adding and subtracfing and the decimals are off when your done with the equation you might end up with two decimals or numbers in the wrong place
