11. an object is thrown in the air with an initial velocity of 5 m/s from a height of 9 m. the equation h(t)-4.95t9 models the height of the object in meters after t seconds. about how many seconds does it take for the object to hit the ground? round your answer to the nearest tenth of a second.

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
