The answers to the questions are:
1. The confidence level is 99 percent.
2. We have to conclude that there is no sufficient evidence available to support this claim because the Confidence interval contains 75 sec.
<h3>How to solve for the confidence level</h3>
1. The confidence level here should be
1- 0.01 = 0.99
= 99 percent
Given that, 99% confidence interval for population mean (μ) is (-34.1 sec u< u < 264.1 ) seconds.
We are to test the claim that the population mean is greater than 75 sec.
2.
The given confidence interval contains the value of 75 sec, so there is not sufficient evidence to support the claim that the mean is greater than 75 sec.

Answer:
D
Step-by-step explanation:
simple : when we have a point defined as (1, 4), it means x = 1, y = 4.
and since the point is on the graph of a function/equation it means that when we use x = 1 and calculate the equation, we get 4 as result (= y). so yes, that means that both sides of the "=" sign are indeed equal for this pair of values, which makes the equation true.
but there will be usually many other pairs that do that too.
200÷P, as you need to to do the equivalent of 20-p-p-p... until you get to 0, which is faster and more simply done with division.
Answer:
Step-by-step explanation:
1: Base Surface Area = π×72
= 153.9380400259 millimeters2
Lateral Surface Area = π×7×√72 + 142
= 344.215921821 millimeters2
Total Surface Area = 498.1539618469 millimeters2
Rounded = 500 millimeters2
2:Base Surface Area = π×52
= 78.539816339745 centimeters2
Lateral Surface Area = π×5×√52 + 102
= 175.62036827602 centimeters2
Total Surface Area = 254.16018461576 centimeters2
Rounded 300 centimeters2
