Answer

500

Step-by-step explanation:

If the biologist tags 25 birds and lets them go, and then catches 100 and 5 of them have the tags, that would mean 20 of them are still out in the wild.

The way to solve this is if you put it into a proportion.

5/100 = 25/x

5x = (100)(25)

5x = 2500

5x/5 = 2500/5

x = 500

5/100=25/500

Step2247 [10]

Answer:

The slopes of line m and p will be the same: 1/25 (I think thats what that says)

Step-by-step explanation:

when two lines are parallel it means they will never touch, and so they must have the same slope. If their slopes were different (even by 1 decimal), they would touch and so would no longer be parallel.

What is the y-intercept of f–1(x)?
wolverine [178]

Answer:

-16

Step-by-step explanation:

The given linear function is ; f(x)=\frac{3}{4}x+12

Let y=\frac{3}{4}x+12.

We interchange x and y.

x=\frac{3}{4}y+12.

We solve for y.

x-12=\frac{3}{4}y.

We now multiply through by \frac{4}{3} to get:

\frac{4}{3}x-12\times\frac{4}{3}=y.

This simplifies to;

y=\frac{4}{3}x-16.

Hence f^{-1}(x)=\frac{4}{3}x-16.

The y-intercept is -16
