probability that a student plays a
sport is 0.20. The probability that a student
is a senior and plays a sport is 0.08.
What is the probability that a randomly selected student plays a sport, given
that the student is a senior?
• A. 0.08
O B. 0.32
• C. 0.17
D. 0.25
Answer:
B. 0.32
I guessed and it was right
The probability that a randomly selected student plays a sport, given that the student is a senior, is 0.32.
The correct answer is B. 0.32.
To find the probability that a randomly selected student plays a sport, given that the student is a senior, we can use the formula for conditional probability:
P(plays a sport | senior) = P(plays a sport and senior) / P(senior)
Given that P(plays a sport and senior) = 0.08
and P(senior) = 0.25,
we can substitute these values into the formula:
P(plays a sport | senior) = 0.08 / 0.25
P(plays a sport | senior) = 0.32
Therefore, the probability that a randomly selected student plays a sport, given that the student is a senior, is 0.32.

a system of equations is shown. 4x-y=5 y=-3 what is the value of x in the solution to this system
Answer:
x = 1 / 2 ( or ) 0.5
Step-by-step explanation:
4x - y = 5
Substitute the value of y = - 3 in the given equation,
4x - ( - 3 ) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2 / 4
x = 1 / 2 ( in terms of fraction )
( or )
x = 0.5 ( in terms of decimal )
Note : -
- ( - 3 ) can be written as - 1 x ( - 3 ).
When a negative number is multiplied with another negative number, the result will be positive number.
Hence,
- ( - 3 ) = + 3

Since a is the first letter in the alphabet
and in total there are 26 alphabet
We divide 1 by 26

Using the assumed values, the lateral surface area of the cylinder is 314 square centimeter
How to determine the lateral surface area?The lateral surface area of a cylinder is:
L = 2πrh
The question is incomplete. Assume the following parameters
Radius, r = 10
Height, h = 5.
Then we have:
L = 2 * 3.14 * 10 * 5
Evaluate the product
L = 314

A rectangle with a perimeter of 18 miles and a width of 7 miles.
What is the length of the rectangle?
Answer:
2 miles
Step-by-step explanation:
A rectangle has two widths
7 + 7 = 14
18-14=4
It also has two lengths
4/2=2
2 miles
Hope this Helps
Happy Earth day
Answer:
2 miles
Step-by-step explanation:
Perimeter is figured out by adding all 4 sides of a rectangle.
So if the width is 7 miles on 1 side, the other width side is also 7 miles.
If the perimeter was 18 miles and 14 miles of that was the width on both sides, that leaves only 4 miles left for the 2 length sides. That means each length side is 2 miles.
