T = half life. Lol stuck on a physics question. I rearranged it to Decay constant = ln(2)/T ... but I have a feeling I have rearranged it wrong.

You have rearranged it correctly.

T = In(2) / D

Move the / D across the equals sign and it becomes T x D = In(2).

Then move the T over the equals sign to give:

D = In(2) / T.

Decay = In(2) / T

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. 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).
