Mr. hauseman has 17 students in his class, three of which are freshman and the others are sophomores and juniors. he is going to randomly draw two students to be partners. he calculates the probability of drawing first a freshman and then a sophomore to be 3 34 . how many sophomores are in the class?

8

Step-by-step explanation:

Total number of students = 17

No. of Freshman = 3

Let the number of sophomore be x

Now we are given that He is going to randomly draw two students to be partners.

He calculates the probability of drawing first a freshman and THEN a sophomore to be

So, probability of drawing a freshman and then a sophomore:

Hence there are 8 Sophomores in the class.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
