Mathematics
1 answer:
krok68 [10]4 years ago
5 0

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.

Stella bought 14 purses for $50. The next day she bought 2 more for a total of $38. What was the mean cost per purse?
denpristay [2]

Answer:

$48.5

Step-by-step explanation:

Given data

Number of purses= 14+2= 16

Cost of 14 purses= $50

Cost of 2 purses= $38

Let us use the weighted cost method

Mean cost = (14*50+ 2*38)/16

Mean cost = (700+ 76)/16

Mean cost = 776/16

Mean cost =$48.5
