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)
5(w - 1) - 2 = 5w + 7
5w - 5 - 2 = 5w + 7
5w - 7 = 5w + 7
5w - 5w = 7 + 7
0 = 14 (incorrect)
there are no solutions to this system...0 solutions
Here, Area of a Triangle = 1/2 * b * h
A = 1/2 * 6 * 8
A = 1/2 * 48
A = 24
Area of two traingles = 2(24) = 48
Now, Area of a rectangle = 25 * 5 = 125
Now, Total area of the figure = 125 + 48 = 173 units2
In short, Your Answer would be Option A
Hope this helps!
