Answer:
.75? A pair of jeans sells for $36 after a 25% discount. What is the original price of the jeans? x-0.25x=36
Step-by-step explanation:
$36. Explanation: To find the sale price we can set up a proportion. 25/100 = x/48. ... Then we subtract this discount from the original price yielding 48 – 12 = 36; thus, she ... This cost will be equal to the percent remaining after the discount.
Answer:
189 components must be sampled.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
That is z with a pvalue of
, so Z = 2.575.
Now, find the margin of error M as such

Assume that component lifetimes are normally distributed with population standard deviation of 16 hours.
This means that 
How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours?
n components must be sampled.
n is found when M = 3. So






Rounding up:
189 components must be sampled.
3694.51 is the answer because the formula you have to use is V=pi r^2h.
V=pi14^2*6
V=pi*196*6
V=pi*1176
V=3694.51
