to determine the number of beavers in a conservation area, a researcher catches and marks 119 beavers. then the researcher releases them. later 89 beavers are caught and it is found that 39 of them are tagged. about how many beavers are in the conservation area?
(round to the nearest whole number as needed.)

, due on march 21, 2019. you!

Let x be the total number of beavers. We mark 119 out of x beavers. Then, we found 39 marked beaver out of 89 caught beavers. So, if we build the proportion

we get, solving for x,

So, it is reasonable to suppose that there are about 272 beavers in total. Note that this is an estimate, both numerically and conceptually, since we have no information about the set of beavers caught at the beginning and the end of our experiment.
