Emma withdraws $20 each week from her bank account. After 3 weeks, she has $150 left in her account. Let `x` represent the number of weeks and `y` represent the amount of money in Emma's bank account.

Write an equation to represent this situation in slope-intercept form `y=mx+b.`

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.)
