A pumpkin is thrown straight down from the top of a 250-foot building with an initial velocity of −14 feet per second. Its position s at time t is described by the function s(t)= -16t^2 - 14t + 250 where s is in feet. What is the pumpkin’s speed at time t = 3 seconds?

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.)
