Louisiana biologists tagged 250 fish in the oxbow lake False River on October 5. On a later date, they found 7 tagged fish in a sample of 350 fish. Estimate the total number of fish in False River to the nearest hundred.

7/350 = 250/x *
7/250 = x/350
250/350 = 7/x

To estimate the total number of fish in False River, we can set up a proportion using the ratio of the tagged fish found to the total fish in the sample.

First, we can set up the proportion:
7/350 = 250/x

Next, we can cross multiply to solve for x:
7x = 350 * 250

Now, divide both sides by 7 to isolate x:
x = (350 * 250) / 7

Finally, we can calculate the value of x, which represents the estimated total number of fish in False River:
x ≈ 12,500

Therefore, the estimated total number of fish in False River is approximately 12,500.

To estimate the total number of fish in False River, we can use a proportion based on the number of tagged fish found in the sample.

First, let's set up the proportion:

7/350 = 250/x

Now, we can cross-multiply and solve for x:

7x = 250 * 350

Divide both sides by 7:

x = (250 * 350) / 7

Now we can calculate the value of x:

x = 12500 / 7

Round the result to the nearest hundred:

x ≈ 1785.71

So, the estimated total number of fish in False River to the nearest hundred is approximately 1800 fish.
