Which system of equations cannot be directly solved by applying the elimination method? A.(12x – 11y = -4 -6x – 11y = 7 B. x – 11y = -6 (x + 12y = -7 7x 11y = 12 --6x - 4y = -21 x + 11y = 7 D. (11y - 12x = 4 ​

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.)
