Mathematics
1 answer:
krok68 [10]4 years ago

Answer:

  522

Step-by-step explanation:

The assumption is that the proportion of tagged fish caught is the same as the proportion of all fish that were caught and tagged:

  (all fish)/(number tagged) = (sample size)/(number in sample tagged)

  all fish = (number tagged) · (sample size)/(number in sample tagged)

  all fish = 174 · 39/13

  all fish = 522

If all the assumptions are reasonable, the number of fish in the lake is estimated at 522.
