The box-and-whisker plots below represent the scores for pre- and post-written tests for applicants obtaining their driver's licenses. A passing score is 70%. A : exactly 25% more applicants passed the post-test than the pre-test
B : exactly 50% more applicants scored below the passing score on the pre-test than on the post test
C : of all the applicants that passed the pre-test, only 25% scored higher than a 90
D : of all the applicants that passed the post-test, only 50% scored between a 70 and an 80

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

answer: (3,11) is your answer.

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
