The surface area would be 33.6
This should be the answer: A ≈ 21.24 in²
Jeweler A: 125, 140, 155, 170, 185, 200
Jeweler B: 140, 152, 164, 176, 188, 200
If you count the hours it would be after 5 hours that they would be the same exact amount. The two jewelers would be paid $200.00 after 5 hours.
Sorry if I did anything wrong. Comment if I left something out or you don't understand.
Answer:
198 is the variance for the number of defective parts made each week.
Step-by-step explanation:
We are given the following in the question:
Number of parts produced each week = 20,000
Percentage of defective parts = 1%
We have to calculate the variance for the number of defective parts made each week.
We treat defective part as a success.
P(Defective part) = 1% = 0.01

Then the number defective parts follows a binomial distribution
.
Formula for variance =

Thus, 198 is the variance for the number of defective parts made each week.
