The table represents data measuring the sound pressure level for noises with various sound pressures.
If the sound pressure level is calculated based on the
sound pressure, which regression equation models the
data?
y= = 80(x) 1.01
y = 80(1.01)
y = 93.62logx + 19.81
y = 93.62 + 19.81logx

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.)
