A mover is loading an elevator with many identical 40-pound boxes. The mover weighs 100 pounds. The elevator can carry at most 1,500 pounds. Write an inequality that says the mover will not overload the elevator on a particular ride.

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.)
