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 200, the proportion of catfish in the pond will be 5.7 20 = x 200 . What is the predicted number of catfish in the pond?

Respuesta :

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

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
