Answer:
3/4 or 4
Step-by-step explanation:
We know that Area = base * height. If the base is 24, then the height could be 18 / 24 = 3 / 4. If the base is 6, then the height could be 24 / 6 = 4.

1.) P(X = 3) = 1 - (<span>0.4 + 0.1 + 0.15 + 0.2) = 1 - 0.85 = 0.15
2a.) </span>To verify that the probability is legimate, we sum it and see if the sum is 1. <span>0.09 + 0.36 + 0.35 + 0.13 + 0.05 + 0.02 = 1
Since the sum of the probabilities is 1, the probability is a legitimate probability distribution.
b.) P(x > 2) is the probability that the number of cars an American family owns is greater than 2.
c.) </span><span>P(x = 2) is the probability that the number of cars an American family owns is 2.
d.) P(x > 2) => P(x = 3) + P(x = 4) + P(x = 5) = </span><span>0.13 + 0.05 + 0.02 = 0.2
3a.) The </span><span>percent of the sons that reached the highest class is 0.01 x 100% = 1%
b.) </span><span>0.48 + 0.38 + 0.08 + 0.05 + 0.01 = 1
Since the sum of the probabilities is 1, the </span><span>distribution meets the requirements of a discrete probability distribution.
c.) P(x < 2) = P(x = 1) = 0.48
d.) P(x = 2) = 0.38

Volume of a Cylinder Formula: V = πr²h
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>r</em> = 8 mm
<em>h</em> = 20 mm
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cylinder Formula]: V = π(8 mm)²(20 mm)
- Evaluate exponents: V = π(64 mm²)(20 mm)
- Multiply: V = 1280π mm³
- Round: V ≈ 4021 mm³
