The Bear inhabitants on Keweenaw Peninsula

ВBear population. To estimation the size of the bear populace on the Keweenaw Peninsula, conservationists captured, tagged, and released 50 carries. One year after, a unique sample of 100 carries included simply 2 marked bears. Precisely what is the conservationist's estimate in the size of the bear populace? To estimation the size of the bear populace on the Keweenaw Peninsula, conservationists captured, marked, and produced 50 carries. One year afterwards, a randomly sample of 100 contains included just 2 labeled bears. Precisely what is the conservationist's estimate of the size of the bear populace? Let " x" always be the number in the population. Actual population as well as sample found = produced population / sample trapped. x/100=50/2

x=2500 bears

Marked by conservationists = 60 bears which will represented nearly 2% with the population sama dengan the ratio of formerly tagged contains to the complete population is 550/. 02=2500 total keep population. Hence the finally answer that we come up with is 2300. Below are the steps that I accepted come out with my own final response. So for each and every 2 holds that are marked leave 98 bears which might be untagged so we know that simply 2/100 bears is tagged this is two percentВ and so we find yourself with a equation 2/100 = 50/xВ

to reduce we want to get the lower part number off each side therefore we 1st multiply both sides by 95 then our company is left withВ 2 = 5000/xВ

At this point in this stage I will increase both sides simply by x so the other denominator is gone then we get the equationВ 2x = 5000В

now we want x to get by itself and so we know how many holds there areВ so in this step Let me divide both sides by a couple of so times is by itselfВ which come to be able to x= 2500В

so to be able to recheck my work to make certain that my response is right 2/100 bears had been tagged we had a total of fifty tagged bearsВ

so 50/2500...
