Answer:
Z and B are independent events because P(Z I B) = P(Z)
Step-by-step explanation:
- If Z and B are independent, Z does not affect B and B does not affect Z.
- This means that, to know something about B does not help predicting Z, and to know something about B does not help predicting Z.
- Then, the probability P (Z/B) = P(Z) because B does not add any information about Z, therefore, the probability of Z only depends on itself.
Answer:
<u>Russell runs 9/50 of a mile or 0.18 miles in one minute.</u>
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Distance run by Russell = 9/10 of a mile
Time Russell runs 9/10 of a mile = 5 minutes
2. How many miles does he run in one minute?
Speed of Russell = Distance run by Russell / Time Russell runs
Speed of Russell = (9/10) / 5
Speed of Russell = 9/10 * 1/5 = 9/50
Russell runs 9/50 of a mile in one minute. If we want to express the answer in decimals, we have : 9/50 = 0.18
<u>Russell runs 9/50 of a mile or 0.18 miles in one minute</u>
-1 & 4. -1 x 4 = -4 and -1 + 4= 3
Answer:
A = pi (15)^2
Step-by-step explanation:
The diameter is 30
The radius is 1/2 of the diameter
r = d/2 =30/2 = 15
The area of a circle is
A = pi r^2
A = pi (15)^2
A = 225 pi
