In a class of 25 students, 15 are female and 16 have an A in the class. There are 12 students who are female and have an A in the class. What is the probability that a student has an A given that the student is female?
Answers
Answer:12/16
Step-by-step explanation:
The probability that a female student has an A in the class is 0.8 or 80%.
How to calculate the probability?To calculate the probability that a student has an A given that the student is female, we can use the formula for conditional probability:
[tex]P(A|F) = \dfrac{P(A U F)} { P(F)}[/tex]
where P(A|F) is the probability of having an A given that the student is female, P(A and F) is the probability of being both female and having an A, and P(F) is the probability of being female.
We are given that there are 25 students in the class, 15 of whom are female and 16 of whom have an A. We are also given that there are 12 students who are both female and have an A.
Using this information, we can calculate the probabilities as follows:
P(F) = 15/25 = 0.6
P(A and F) = 12/25
The probability that a student has an A given that the student is female is:
[tex]P(A|F) = \dfrac{P(A U F)} {P(F)} \\P(A|F) = \dfrac{\dfrac{12}{25} }{ (\dfrac{15}{25})} \\P(A|F)= 0.8[/tex]
The probability is 80%.

of campers, y, that there are for x counselors. Then graph.
Answers
Answer:
The equation would be 9x=y
Step-by-step explanation:
The equation for the counselor and the camper will be y = 9x
What is an equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
At a summer camp, there is one counselor for every 9 campers.The equation will be formed as:-
The number of campers, y, that there is for x counselors so equation will be given as.
Y = 9x
For one counselor there are 9 campers and for 2 there will be 18 counselors the graph of the equation is also attached with the answer.

Answers
Answer:
It's a 180 rotation
Step-by-step explanation:
The first set of chords are in the first quadrant while the second set of chords are in the third quadrant. If you draw the first triangle on a second sheet of paper in the same place a the first triangle and hold the paper so that the triangle you drew of the first triangle is directly on top of the first triangle and then hold the paper at the point (0,0) and move the paper 180 degrees, it doesn't matter which direction cause it's 180 degrees, the points of the triangle will have ended up in the third quadrant. So it's 180 degree rotation

8 + x = 3.5x - 1
x - 3.5x = -1 - 8
-2.5x = -9
x = 3.6
Answer:
x = 3.6
Step-by-step explanation:
8 + x = 3.5x - 1
subtract 8 from both sides
x = 3.5x - 9
subtract 3.5x from both sides
-2.5x = -9
divide by -2.5 from both sides

The slope of the line that goes through points (−3,−4) and (−7,16) is (-5)
What is slope?
If a line passes through [tex](x_1,y_1) \: and \: (x_2,y_2)[/tex] then slope of line will be [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Know more about line:
A line has length but not width. A line is a type of geometric shape that can move in either direction. A line consists of an infinite number of points. It is infinite and has no end on either side. The row is one-dimensional.
In geometry, the term line or straight line was introduced by ancient mathematicians to denote straight objects of negligible width and depth. It is often described as two points.
A line in a plane is often defined as a set of points whose coordinates correspond to a given linear equation in the sense of analytic geometry, while a line can be an independent object distinct from the points on it. drop geometry.
Here given two points are (−3,−4) and (−7,16).
According to rule,slope of the line that goes through points (−3,−4) and (−7,16)
[tex] = \frac{16 - ( - 4)}{ - 7 - ( - 3)} \\ = \frac{16 + 4}{ - 7 + 3} \\ = \frac{20}{ - 4} \\ = - 5[/tex]
Therefore, required slope of the equation is (-5).

As per the given figure, this means (x + 7) = 90 degrees
⇒ (x + 7) = 90
⇒ x = 90 - 7
Apply the subtraction operation, and we get

-3x + 40
Step-by-step explanation:
The constant given is 40 gallons and the rate at which the water in the bathtub decreases is 3 gallons per minute.
To write this as an equation we model 40 as the starting constant that is positive and, because the water is decreasing, we use a negative slope.
-3x represents the decrease in water over x intervals (Which in this case is minutes) and 40 gallons represent the initial value (water in the bathtub).
Therefore the water in the bathtub can be modeled with the equation
-3x + 40

Complete the square and put this function in vertex form: f(x)=x^2+20x+96
Answers
Answer:
f(x) = (x+10)^2 - 4
Step-by-step explanation:
vertex form is y = a(x-h)^2+k
to complete the square, we want to add a number on both sides so x^2+20x+whatver the number is, is the square of something
to find that number take 20, divide by 2, and then square it to get 100.
so, you would get f(x)+100 = x^2+20x+100+96
subtract 96 on both sides: x^2+20x+100 = f(x) + 4
factor: f(x) = (x+10)^2 - 4
