Answer: 28.6
Step-by-step explanation:
Prime factors are multiplying numbers that cannot be divided into smaller numbers.
Let's break down 92.
Divide 92 by 2.
2 x 46.
We can still break this down.
Divide 46 by 2.
2 x 2 x 23.
This is your prime factorization of 92.
I hope this helps!
Answer:
Step-by-step explanation:
Are we supposed to fill in the blanks? How?
The average of the 3 grades = (81+85+95) /3
=87
This counts as 2/3
of the final grade:
87 * 2/3 = 58 points
For a grade of 90, they still need 90 -58 = 32 points
Let x = final exam score
The final exam is worth 1/3, so we get:
1/3x = 32
To get x, multiply both sides by 3:
x = 32 *3
x = 96
They need a 96 on the final exam.
Answer:
40%
Step-by-step explanation:
If we call by A the members that prefer swimming on weekends and by B the members that are women, we have that:
P(A) = 0.25
P(A and B) = 0.1
The probability of a member being female given that the person prefers swimming on weekends can be expressed as P(B|A) (that is, probability of B given A).
To find this value, we can use this formula:
P(B|A) = P(A and B) / P(A) = 0.25
So we have that:
P(B|A) = 0.1 / 0.25 = 0.4 = 40%
