What’s the volume of a cylinder
Answer:
5 percent of 120,000 is 6,000 than 6,000*25 the years is going to be 150,000 than add that with 120,000 you get 270,000
Answer:
405
Step-by-step explanation:
To find sample size, use the following equation, where n = sample size, za/2 = the critical value, p = probability of success, q = probability of failure, and E = margin of error.
The values that are given are p = 0.84 and E = 0.03.
You can solve for the critical value which is equal to the z-score of (1 - confidence level)/2. Use the calculator function of invNorm to find the z-score. The value will given with a negative sign, but you can ignore that.
(1 - 0.9) = 0.1/2 = 0.05
invNorm(0.05, 0, 1) = 1.645
You can also solve for q which is 1 - p. For this problem q = 1 - 0.84 = 0.16
Plug the values into the equation and solve for n.
Round up to the next number, giving you 405.

Step-by-step explanation:
I'm doing seven.
<em><u>x = -2</u></em>
y = 2^(-2 -1) + 2
y = 2^(-3) + 2
y = 1/2^3 + 2
y = 1/8 + 2
y = 2.125 which is a guess on the graph.
<em><u>x = - 1</u></em>
y = (2)^(-1 -1) + 2
y = (2)^-2 + 2
y = 1/4 + 2
y = 2.25
x = 0
y = 2^(0 - 1) + 2
y = 2^(-1) + 2
y = 1/2 + 2
y = 2.5
<em><u>x = 1</u></em>
y = 2^(1 - 1) + 2
y = 2^0 + 2 If the power of a number = 0 then the result = 1. The only exception to that is 0^0
y = 1 + 2
y = 3
Eight
<em><u>x = -1</u></em>
y = (1/2)^(-1 + 1) + 2
y = 1 + 2
y = 3
<em><u>x = 0</u></em>
y = (1/2)^(0 - 1) + 2
y = (1/2)^-1 + 2 Turn the 1/2 upside down
y = 2 + 2
y = 4
<em><u>x = 1</u></em>
y = (1/2)^(1 + 1) + 2
y = (1/2)^2 + 2
y = 1/4 + 2
y = 2.25
<em><u>x = 2</u></em>
y = (1/2)^(2 + 1) + 2
y = (1/2)^3 + 2
y = 1/8 + 2
y = 2.125
A) 36960 feet approximately
B) 8.661 inches approximately
C) 768 ounces approximately
