Which second degree polynomial function has a leading coefficient of 2 and roots –3 and 5?

f(x) = 2x2 + 4x – 30

f(x) = 2x2 + 2x – 15

f(x) = 2x2 – 4x – 30

f(x) = 2x2 – 2x – 15

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.)
