PLEASE HELP!! polygon ABCD shown in the figure, is dilated by a scale factor of 8 with the origin as the center of dilation, resulting in the image A’B’C’D’. the slope of C’D’ is _

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.)
