A bag contains 6 red marbles, 6 purple marbles, and 6 yellow marbles. What is the probability of randomly selecting a yellow marble from the bag?

1/3

Step-by-step explanation:

There is a bag of marbles. If you add all of them together you get 18 marbles total. Marbles are red, 6 are purple, and 6 are yellow. Since each color is 1/3 of the bag ( 18 divided by 6 is 3) you will of have 1/3% chance of getting a yellow marble. 1/3 is equal to 33.3%.

c.)

step-by-step explanation:

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.
