1. At a particular intersection there is a 30% chance a vehicle will turn left and a 45% chance it will turn right. You watch the first vehicle you see and the 50th vehicle you see in the next hour and record which direction they go (Left, Straight, or Right). Let X be the random variable that counts the number of vehicles that turned right. A. Write out the probability distribution for the random variable X.

Ateacher noticed 5/8 of the students were wearing either blue shorts or white shorts. write two different ways this could be done.

Which of the following parabolas opens down?

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
