To track the fish population in a certain area a sample of 35 fish were tagged and released. Later another sample was caught and 13% had tags Approximately how many fish are in the ponds

Step-by-step explanation:

The question says that the fish population of an area is being tracked and a certain of 35 were collected, tagged and released.

Later another sample was collected and it revealed that 13% of those fishes caught were the ones tagged previously.

The estimated number of fishes in that area will be:

Let X = number of fishes available in that area

13 percent of fishes caught at the second sample collection were tagged

Number of fishes collected are 35

13/100*X = 35

X = 3500/13

X = 269

The number of fishes in the pond is around 269
