20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
|-1/5| < |-1/3| < |-7|
Your answer:
B. y = -1/5 x^2; y = -1/3 x^2; y = -7x^2
Look at the picture.
1/2 because when you divide by 1/2 you get 1/6 , if you do the problem backwards you get 1/6
Answer:
y is less than or equal to 1 OR y is greater than or equal to 6
