Acertain group of students, the probability of a randomly chosen students is being male is 40%, the probability of the students studying in spanish it's 18%, and the probability that a student who is known to be male also studies spanish is 25%. what is thr probability of the student being both a male and studying spanish.
a. 10%
b. 45%
c. 4.5%
d. 7.2%

In this question, we're trying to find the probability of a male that also studies Spanish.

In this case, we know that:

With the information above, we can find the probability.

To find the probability, we would need to find how much of 40 is 25%.

To do this, we would multiply 0.4 (40%) by 0.25 (25%) to find our probability.

Solve:

The probability of a male that studies Spanish is 10%

Your answer would be A). 10%

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
