If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?

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.)

Run a linear regression to determine an equation (y=mx+b y=mx+b)
