Question 694445: 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?
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 in the population. Real population / sample caught = released population / sample caught.
x/100=50/2
x=2500 bears
Tagged by conservationists = 50 bears which represented an estimated 2% of the population = 50/.02=2500 total bear population.

For the second problem in this assignment I am asked to solve this equation for y. The first thing I notice is that it is a single fraction (ratio) on both sides of the equal sign so basically it is a proportion which can be solved by cross multiplying the extremes and means.

This is the proportion set up and ready to solve. I will cross multiply the x and y setting the extremes equal to the means.
(y-1)*4=(x+3)-(-3)
4y-4=-3x-9
4y=-3x-9+4
4y=-3x-5 Divide both sides by 4
4y = -3x � 5 Simplify
4 4 4
4y = -(3) * x � 5
4 (4) 4
y = -(3) * x-5 Answer to problem 10 on page 444.

Question 695975: Hi,
My Son as these two equations that we can not get the right answers needed. Both of them have to do with finding the center point and then plot them to a graph. We would be sure glad if one of you could give us a helping hand and see our mistakes.
The first one is X^2 + Y^2 - 20X + 24Y + 100 = 0
Our work is this X2 + Y2 - 20X + 24Y = - 100
X2 - 20X + Y2 + 24y = - 100
Y2 + 24Y = 0
(X - 10)2 + (Y + 12)2 + 144 = 100
(X - 10)2 + (Y + 12)2 = + 144
center is (10, -12) on the graph
The next one is X^2 + Y^2 + 8X - 16Y - 20 = 0
Again our work X2 + 8X + Y2 - 16Y - 20
(X + 4)2 + (Y - 8)2 = 160
center is (-4, 8) on the graph
Half a change if one of them are right We have no idea?
Thanks for your help
