A) 58
B) 116
C) 232
D) 406

Answer 1

To find out how many trout you would expect in the creek based on your sample, use a proportion - 4 trout / 7 fish = x trout / 406 fish. Solving for x gives us approximately 232 trout.

Step-by-step explanation:

To find out how many trout you would expect in the creek based on your sample, you can set up a proportion using the information given. The proportion can be set up as:

Number of trout caught / Total number of fish caught = Number of trout in the creek / Total number of fish in the creek

Using the data given, the proportion would look like this:

4 trout / 7 fish = x trout / 406 fish

Cross-multiplying and solving for x:

4 * 406 = 7 * x

1624 = 7 * x

x = 1624 / 7

x ≈ 232

Therefore, based on your sample, you would expect there to be approximately 232 trout in the creek.
