Time (milions of yeas) If you started with a 125g sample of U-235, how much of the sample would be remaining after 3 half-lives and how many years would
have passed?
A 15.6g would remain after 3000 million years had passed.
OB 15.6g would remain after 2100 million years had passed.
OC 12.5g would remain after 2100 million years had passed.
OD. 12.5g would remain after 3000 million years had passed.
oh

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

do i do it on a graph?

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
