11×24=quarts per day. That's 264.
264/12=full barrels per day. That's 22.
120/22=frequency of pick ups. That's 5.45. So the barrels get picked up every 5 and a half days.
<span>A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 18 minutes. How large a sample should she take to estimate the mean time to within 4 minutes with 97% confidence?
-----
n = [z*s/E]^2
---
n = [2.17*18/4]^2 = 96 when rounded up

Answer:
where is figure by the way
Answer:
A
Step-by-step explanation:
So from 36 to 60 is add 24 and for 3 to 5 is add 2 so that gave u 24/2 that is = 12 and u do ur Y=MX+B 36=(12)(3)+b = 36=36+b then u subtract 36 = to 0 so B=0 and that how u get Y=12x.
To test whether it's a factor:
-- Divide the big number by it. 81 / 6 = 13.5 .
-- If the quotient is a whole number,
then the small number is a factor
of the big number. 13.5 is not a whole number.
-- If the quotient is not a whole number,
then the small number is NOT a factor
of the big number. 6 is NOT a factor of 81 .
