Answer to Question 1

We hope that they will make such a change. To be sure, the initial investment is
high, and some families might be too poor to afford the cost, even though they would
recoup the cost very rapidly. Look for some logic in the students' explanations.

Answer to Question 2

If the force exerted on the mass is twice as large and the mass is also twice as
large, the acceleration (the rate of change in velocity) is the same in both cases.

These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. 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).
