At 6: 00 a. m. the temperature was 33°f. by noon the temperature had increased by 10°f and by 3: 00 p. m. it had increased another 12°f. if at 10: 00 p. m. the temperature had decreased by 15°f, how much does the temperature need to rise or fall to return to the original temperature of 33°f?

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.)
