finding the population of an area. Conservationists are able to predict the population of bear’s in their area by comparing information collected from two experiments. In this problem, 50 bears in Keweenaw Peninsula were tagged and released so conservationists could estimate the bear population. One year later, the conservationist took random samples of 100 bears from the same area, proportions are able to be used in order to determine Keweenaw Peninsula’s bear population. “To estimate the size of the

Proportions To estimate the size of the bear population on Keweenaw Peninsula, conservationists Captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears. The question I am asked is what do conservationist’s estimate of the size of the bear population? You will notice while reading question #56 on page 437, we are to assume that the ratio of originally tagged bears to the whole population is equal to the ratio of recaptured tagged bears to the

solve. The first one is problem #56 from page 437. To estimate the size 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 conservationist’s estimate of the size of the bear population? Let “x” be the number we will find for the bear population. x = 100 I will cross multiply this equation. 50 2 2x = 50 * 100 After cross multiplying

1 Bear population. To estimate the size 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 conservationist's estimate of the size of the bear population? I think using a simple ratio equation would work here, let b = bear population = cross multiply 2b = 50*100 2b=5000 divide 2 by 5000 5000 =b 2 b=2500 answer Problem 2 For

about bear population. Putting the word problem into an equation we get b/50 = 100/2. We must solve the equation to find what b will equal. Then we have a second problem, example B., which is Y-1/x+3 = -3/4. We will solve example B. until we get to the linear equation format or an extraneous solution. Both examples of proportions will be solved in the same process though the problems themselves seem very different. A. To estimate the size of the bear population on the Keweenaw Peninsula, conservationists
