There are 190 students taking band, chorus, or both. if there are 180 students taking band and 60 students in both band and chorus, how many students are only in chorus? 70 60 10 120

If there are 180 students taking band and 60 students in both band and chorus, then 180-60=120 students are taking only band.

Now:

Then 190-(120+60)=190-180=10 students are taking only chorus.

correct choice is C.

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.
