Using six random samples, the average number of catfish in the samples was 5.7. If the total population of fish in the pond is 2
00, the proportion of catfish in the pond will be 5.7 20 = x 200 . What is the predicted number of catfish in the pond?
2 answers:
Answer:57 = x
Step-by-step explanation:
Using the proportion given, there will be 57 catfish in the pond.
The proportion given to us is
5.7/20 = x/200
Cross multiply:
5.7*200 = 20*x
1140 = 20x
Divide both sides by 20:
1140/20 = 20x/20
57 = x
Using the proportion given, there will be 57 catfish in the pond.
The proportion given to us is
5.7/20 = x/200
Cross multiply:
5.7*200 = 20*x
1140 = 20x
Divide both sides by 20:
1140/20 = 20x/20
57 = x

It is B because 40x32=1280 and 5x4=20 then divide 1280 by 20 and you get 64 but you can’t have 64 so you would need to only have 60 so the answer is B
I think it's 9 but I could be wrong
D. 11,475 (135/200= .675 =67.5 %) (67.5% x 17,000 = 11,475)
By (i believe) multiplying the base by the height. I hope this helps!
