Question

Lisa graduating student needs to estimate how many catfish are in a local River first she tags 220 catfish later she captures 260 catfish of which 13 had takes to the nearest whole number what is the best estimate of catfish population

Answer 1

Answer:

4400 fish.

Step-by-step explanation:

Let x represent number of total fish in the river.

We have been given that Lisa tags 220 catfish. Later she captures 260 catfish of which 13 had tags.

We will use proportions to solve our given problem as:

$\frac{\text{Tagged fish}}{\text{Total fish }}=\frac{\text{Caught fish}}{\text{Total fish }}$

$\frac{13}{260}=\frac{220}{x}$

$13x=220\times 260$

$x=\frac{220\times 260}{13}$

$x=220\times 20$

$x=4400$

Therefore, there are approximately 4400 fish in the river.
