Final answer:
To find the probability that the sample mean will be within a certain range, we need to calculate the z-scores and look them up in the z-table.
Explanation:
To find the probability that the sample mean will be within +/- 8 of the population mean, we need to convert this range to z-scores. The z-score formula is calculated by subtracting the population mean from the sample mean and dividing by the standard deviation divided by the square root of the sample size.
For +/- 8, the z-score will be (8 - 0) / (70 / sqrt(125)) = 2.09.
Using the z-table, we can find the probability associated with a z-score of 2.09, which is approximately 0.9828. Therefore, the probability that the sample mean will be within +/- 8 of the population mean is 0.9828.
Similarly, for +/- 17, the z-score will be (17 - 0) / (70 / sqrt(125)) = 4.18. Using the z-table, the probability associated with a z-score of 4.18 is nearly 1.0000. Hence, the probability that the sample mean will be within +/- 17 of the population mean is 1.0000.

45,000 seats
5/8 of the seats were bought for the next game.
To get the exact number of seats, we need to multiply the total number of seats by the fraction bought.
45,000 * 5/8 = (45,000 * 5) / 8 = 225,000 / 8 = 28,125 seats
5/8 of the total seats is 28,125 seats which are all unavailable.
8/8 - 5/8 = 8-5/8 = 3/8 is the fraction of the seats available.
45,000 - 28,125 = 16,875 seats available.
45,000 * 3/8 = (45,000 * 3) / 8 = 135,000 / 8 = 16,875

The volume of the cylindrical trunk is calculated as approximately: B. 21.17 ft³.
What is the Volume of a Cylinder?
Volume = πr²h
The dimensions of the cylindrical trunk are:
- Height = 13 feet
- Circumference = 4.5 feet
Find radius (r) using the circumference of a circle formula:
4.5 = 2(π)r
4.5/2π = r
r = 0.7 feet
Volume of the cylindrical trunk = π(0.7²)(13) = 20.01 ft³ (close to 21.17 ft³)
The approximate volume of the cylindrical trunk is: B. 21.17 ft³.

r = 4.5 / 2pi = 0.7162
Volume of a cylinder = pi * r^2 * h
= pi * (0.7162)^2 * 13
=20.95
which is approximately close to 21.17ft^3
Answer: 21.17ft^3

Answer:
79
Step-by-step explanation:
Since the triangles are similar, the sides that are the same length have angles that are the same size at the top.
We are given that these two are congruent in the text. We have two identical elements so far — angle of 35 and the side opposite the angle of 35 (which is what the little line in the middle means) — but we are missing that angle G.
Since angle G in the second triangle is in the same place as the angle of 79 in the first one (between the side with the line in it and the angle of 35), we know that angle will be also 79, given that the triangles are congruent (or identical, in other words). So your answer is 79°.
