You go to the doctor and he gives you 16 milligrams of radioactive dye. After 16 minutes, 7.25 milligrams of dye remain in your system. To leave the doctor's office, you must pass through a radiation detector without sounding the alarm. If the detector will sound the alarm if more than 2 milligrams of the dye are in your system, how long will your visit to the doctor take, assuming you were given the dye as soon as you arrived? Give your answer to the nearest minute. You will spend ????? minutes at the doctor's office.

An automotive researcher wanted to estimate the difference in distance required to come to a complete stop while traveling 40 miles per hour on wet versus dry pavement. Because car type plays a role, the researcher used eight different cars with the same driver and the same tires. The braking distance (in feet) on both wet and dry pavement is shown in the table. Test to determine whether it takes longer to brake on wet pavement than dry. Car number 1 2 3 4 5 6 7 8 Wet braking distance 106.9 100.9 108.8 111.8 105.0 105.6 110.6 107.9 Dry braking distance 71.8 68.8 74.1 73.4 75.9 75.2 75.7 81.0
