A 250-foot length of fence is placed around a three-sided animal pen. Two of the sides of the pen are 100 feet long each. Does the fence form a right triangle? Converse of the Pythagorean Theorem

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.)
