At a high school, the probability that a student is a senior is 0.25. The
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 veterinary office pays PupFood $32. 75 for each bag of dog food. If the office spent $655, how many bags of food did they purchase? (Use only a number for your answer)
Answer:
20 Bags
Step-by-step explanation
The total costs would be given by the formula:
Total $ = (Bags of Food)*(Cost/bag)
We know total cost and price per bag:
$655 = (Bags of Food)*($32.75/bag)
Bags of Food = ($655/$32.75)
Bags of Food = 20 Bags

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.

Answer:
F. 12
Step-by-step explanation:
There are two right triangles.
Hence, we can solve for the missing side using the Pythagorean Theorem using one of these triangles.
Let's take the left one.
a² = (8√3)² - (4√3)²a² = 192 - 48a = √144 a = 12The length of the altitude is 12.
The correct option is : F. 12
The length of an altitude is 12 units.
The correct option is 12.
What is Pythagoras' theorem?Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle is equal to the sum of the squares of the other two sides.
As per the information provided, it is given that the triangle is an equilateral triangle.
The side of the triangle is 8√3 units.
To find the length of the altitude of the equilateral triangle:
Let the length of altitude is h units.
Then, as per Pythagoras' theorem,
h² = (8√3)²- (4√3)²
h² = -16(3) + 64(3)
h = -48 + 192
h² = 144
h = 12
Therefore, h = 12 units.

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

⇢ 0. 0385
Probability = 0. 0385

= {A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z}
= 26 alphabets.
Out of all these 26 alphabets, we need to find the probability that the letter chosen at random will be 'A'.
Probability that the letter chosen at random is 'A'
