# Hofstra University Radioactive Decay and Plot Questions Procedure Discussion

Iβm studying for my Statistics class and donβt understand how to answer this. Can you help me study?

1. In radioactive decay from an initially pure parent, the parentβs and daughterβs half-lives are the same, i.e., π12,πβ=π12,π·β=π12β.: (20 points) a. What are ππ· and π΄π· as a function of time and ππ and π΄π?
2. b. What is the general form for π‘π,ππ and π‘π΄,ππ, the times when the daughterβs population and activity are equel to those of the parentβs?
3. c. What is π‘πππ₯, the time when does π΄π· reach a maximal?
4. d. Plot the populations of parent and daughter as a function of time for a value of π12β of you choice to demonstrate that π‘π,ππ and π‘π΄,ππ and π‘πππ₯ on the plot are the same as you derived in b. and c.
