Well the factors of "72" is→ 1,2,3,4,6,8,9,12,18,24,36,72
To find the factor(s) "72" just write out the muliples that equals 72
We have the following equation:
V = (1/3) * (pi) * (r ^ 2) * (h)
To clear r we must follow the following steps:
1) Divide both sides of the equation by pi*h
2) Multiply both sides of the equation by 3
3) take de square root of both sides of the equation
Answer:
Confidence interval for the mean consumption of milk per week among males over age 25 in 85% confidence level is (2.8≤μ≤3.0)
Step-by-step explanation:
Consumption of milk among males over age 25 can be found using the formula:
M±
where M is the <em>sample mean</em>, z is the corresponding <em>z-score for 85% confidence level</em>, s is the <em>population standard deviation</em>, N is the <em>sample size</em>.
In this sample, mean of milk consumption per week among males over age 25 is 2.9 liters. Corresponding z-score for 85% confidence interval is 1.440. standard deviation of the sample is 1.1. And sample size is 513. When we put these numbers in the formula, we got:
2.9±
=2.9±0.07
A) The correct way to write 1/4 as a precent is 25%.
because....
1÷4= .25. and .25×100= 25%
b) The reporter most likely forgot to multiply by 100. The reporter instead just found what 1/4 was as a decimal, not a precent.
