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
Answer:
34.98yd^3
Step-by-step explanation:
Volume of a sphere V=4/3πr3
Where V = 2240yd^3
π = 3.14
2240 = 4/3×3.14×r^3
2240 = 4.1866r^3
r^3 = 2240/4.1866
r^3 = 534.784
r = ( 534.784 )^1/3
r = 8.1169
Since each dimension is to be multiplied by 1/4
Hence, 1/4×8.1169
r = 2.029.
New volume will be
V = 4/3×3.14×2.029^3
V = 4/3×3.14×8.3558
V = 34.98yd^3.

Answer:
0.20 dollars/mile
Step-by-step explanation:
The slope actually has units. It has the meaning of 20 cents per mile. The units are cents per mile.
But it can also be 0.20 dollars/mile which is probably the way you should interpret it in a math class. That way it matches the units of the 50 which is for certain in dollars.
