Bear population. To estimate the size
Use a proportion to solve
of the bear
population on the Keweenaw Peninsula, conservationists
captured, tagged, and released 50 bears. One year later, a
random sample of 100 bears included only 2 tagged bears.
What is the conservationistâ€™s estimate of the size of the
bear population

2/50=100/x cross multiply
2x=500 divide by 2
x=250 result

Azteca, 50(100) = 2500 not 250
or
it appears that 2/100 or 2% of the bear population was tagged.
So the 50 must be 2% of the bear population
.02x = 50
x = 50/.02 = 2500

I think that the answer is 2/100=50/2 cross multiply it to make it 2x2=4 and 50x 100 is 5000 or 2/100= 2/50 cross multiply it to get 100 and 200 divide it by 2 to get 100 and to get 50...I think i messsed up :/
