If sr is 4.5cm and tr is 3cm, what is the measure in degrees of angle s?

Graph the line y=4/3 x+1 . use the line tool and select two points on the line.

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.)
