The height h, in feet of a model rocket 1 seconds after launch is given by the equation h = 245t-162. As the rocket descends, it deploys a
recovery parachute when it reaches 325 feet above the ground. Express
your final answer to the nearest tenth place.
How long after the parachute is launched does the parachute
deploy?

Aprobability experiment is conducted in which the sample space of the experiment is s={7,8,9,10,11,12,13,14,15,16,17,18 }, event f={7,8,9,10,11,12}, and event g={11,12,13,14}. assume that each outcome is equally likely. list the outcomes in f or g. find p(f or g) by counting the number of outcomes in f or g. determine p(f or g) using the general addition rule.
