Select all polynomials that are divisible by (x + 1). Choose all answers that apply:
A(x) = x4 – 3x3 – 4
B
B(x) = x4 + 2x + 1
C(x) = x3 – 3x2 + 4x – 2
D(x) = x3 + 2x2 – 5x – 6

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.)
