9) Choose the standard form for the equation of the hyperbola.
(x-2)'2/4 - (y-3)'2/5=1
3) Choose the best answer. In your sock drawer, you have 12 blue socks and 12 yellow socks. It is dark in the morning when you are getting dressed, and you can't see the color of the socks. What is the probability of randomly picking a yellow sock?
1/2

6) Choose the best answer. In your sock drawer, you have 12 blue socks and 12 yellow socks. It is dark in the morning when you are getting dressed, and you can't see the color of the socks. Suppose you pick two socks and one is yellow and one is blue. What is the probability that the third sock you pick will be blue?

Independent
5) Choose the best answer. In your sock drawer, you have 12 blue socks and 12 yellow socks. It is dark in the morning when you are getting dressed, and you can't see the color of the socks. Your first sock picked is yellow, and you do not want to wear yellow socks, so you put it back in the drawer and pick again. What is the probability of randomly picking a blue sock this time? Are the two sock picks independent? Probability: Independent or dependent:
c. 1/2 d. independent
8) Choose the inverse of the function.
g(x)=-4x+3
