A stunt motorcyclist makes a jump from one ramp 20 feet off the ground to another ramp 20 feet off the ground. The jump between the ramps can be modeled by LaTeX: y\:=\:-\frac{1}{640}x^2+\frac{1}{4} x\:+\:20y = − 1 640 x 2 + 1 4 x + 20 where x is the horizontal distance (in feet) and y is the height above the ground (in feet). What is the distance between the ramps?

The host of a game show is holding a bag with chips to see what prizes the contestants will play for. five (5) of the chips say “new car” ten (10) of the chips say “new tv” three (3) of the chips say “trip to france” contestant named “patty” reaches into the bag. a. what is the probability of choosing a tv chip? b. what is the probability of choosing a car chip next without replacing the 1st chip? c. are these dependent or independent events?
