The voltage in a house is measured to be 122.5 V. What is the current drawn by a 75.0-W light bulb?

Question 2

The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
