The area of the rectangle shown is at most 140 square centimeters. a. write and solve an inequality to find the possible values of x. b. based on the answer in part (a), is it possible for the rectangle to have a length of 15 centimeters? explain

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.)
