1. A rocket carrying fireworks is launched from a hill so feet above alake, The rocket will fall into the lake after exploding at its maximum height. The rocket's height above the surface of the lake is represented by A = -167 +64 + 80. How many seconds after the rocket launched with hit the lake Define your terms: Now. set up the quadratic formula: x -(.) Iſ ) 2 - 46 20 )

Part A Find the solutions to the quadratic formula

Part B: Which solution is the correct solution for this scenario Justify your answer​

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable
