Answer: (1.4964, 1.5126)
Step-by-step explanation:
We know that the confidence interval for population mean is given by :-

, where
= population standard deviation.
n= sample size
= Sample mean
As per given , we have
σ = 0.01 inches
n= 10

Also, the critical value for 99% confidence interval =
[From x-value table.]
[Significance level =1-0.99=0.01 and
is 2.576.]
Then, the 99% two-sided confidence interval on the mean hole diameter will be :-

Hence, the required confidence interval = (1.4964, 1.5126)
Try doing (0,-2) for the y intercept
3.833333333 as a fraction is 3 5/6.
It need a lone number. so something like x2+x+3
Answer:
900 sq ft
Step-by-step explanation:
The area of a trapezoid is (Base 1 + Base 2) * height/2. So to plug the numbers in...
(30+60)20/2
90*20/2
1800/2
900 sq ft
