Question

select the button to take a sample of fish. take two samples of fish from a pond and analyze the results. what is the average number of bass found in both samples? what is the ratio of the average number of bass to the average number of fish in each sample? fish type sample 1 sample 2 brook trout 3 5 catfish 9 9 smallmouth bass 8 6

Explanation:

Step1: Calculate average number of bass

The number of small - mouth bass in sample 1 is 8 and in sample 2 is 6. The formula for the average of two numbers $a$ and $b$ is $\frac{a + b}{2}$. Here, $a = 8$ and $b = 6$, so the average number of bass is $\frac{8+6}{2}=\frac{14}{2}=7$.

Step2: Calculate average number of fish in each sample

The total number of fish in sample 1 is $3 + 9+8=20$, and in sample 2 is $5 + 9+6 = 20$. The average number of fish in each sample is $\frac{20 + 20}{2}=20$.

Step3: Calculate the ratio

The ratio of the average number of bass to the average number of fish in each sample is $\frac{7}{20}$.

Answer:

The average number of bass found in both samples is 7.
The ratio of the average number of bass to the average number of fish in each sample is $\frac{7}{20}$.
