Answer:
she needs 3 3/4 yards more to make a quilt
Step-by-step explanation:
Total cloth needed = 10 1/2 yards
she has a total of = 2 1/2 + 4 1/4
= 2+4 + 1/2 +1/4
=6 + 2+1/4
=6 3/4 yards
she needs more = 10 1/2- 6 3/4
= 21/2- 27/4
= 42-27/4
=15/4= 3 3/4 yards
I think the answer is 15 and Put an number 0 150

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.
