The most appropriate comparison of the spreads will be A) The median for the Wolverines 80 is more than the median for the Panthers 70
You need to use the conditional probability formula:
P(A|B) = P(A∩B) / P(B)
Key:
P(A|B): Probability of A given B
P(A∩B): Probability of A and B
If we say A is the event that the train arrives on time and B is the event that the train leaves on time, then according to the information:
P(B) = 0.4
P(A∩B) = 0.28
Just insert into the formula:
P(A|B) = 0.28 / 0.4 = 0.7
(or 70% as a percentage).
Given
Shamariah collects silk roses.
She had 17 silk roses in a vase.
Six friends each gave her 3 more roses
Find out the roses does Shamariah have now.
To proof
As given in the question
She had 17 silk roses in a vase
Six friends each gave her 3 more roses
let the total number of roses shamariah have = x
The equation becomes
x = 17 + 6 × 3
x = 17 + 18
x = 35
Number of roses shamarah have now is 35.
Hence proved
Answer:
There are 1,500 books in Library 1
Step-by-step explanation:
30 = 0.02x
Divide 0.02(or 2%) from both sides
1,500
You need to divide the 20 books by the percentage that they are compared to the total amount.
