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.

Answer:
Step-by-step explanation:
Jared wrote the equation as,
k + (k + 1) + (k + 2) = 4k
Solution for k will be,
3k + 3 = 4k
4k - 3k = 3
k = 3
For k = 3, consecutive numbers will be → 3, 4, 5
Jared did not get the correct answer.Solution to this equation is k = 3, giving 3, 4, and 5 as three integers. However, 3 and 5 are not even integers. He should have used the equation k + (k + 2) + (k + 4) = 4k, which gives k = 6 and the correct answer is 6, 8, 10.
