To find the mean number of pets, we add up the total number of pets and then divide by the number of responses.
0 (3 x's) = 0 * 3 = 0
1 (4 x's) = 1 * 4 = 4
2 (2 x's) = 2 * 2 = 4
3 (6 x's) = 3 * 6 = 18
4 (2 x's) = 4 * 2 = 8
5 (0 x's) = 0
6 (0 x's) = 0
7 (0 x's) = 0
8 (0 x's) = 0
9 (1 x) = 9 * 1 = 9
10 (0 x's) = 0
Total number of pets = 0 + 4 + 4 + 18 + 8 + 9 = 43
Number of responses = 3 + 4 + 2 + 6 + 2 + 1 = 18
Mean number of pets = Total number of pets / Number of responses
Mean number of pets = 43 / 18
Mean number of pets ≈ 2.39
Therefore, the mean number of pets is approximately 2.39.
Anna asked her classmates how many pets they have. This line plot shows the results. Find the MEAN number of pets.
Process: Each x represents a number. Write down the numbers that the x's represent. Add the numbers together. Divide by the number of x's. Remember, "0" still counts as a number!
numberline goes from 1 to 10
0=3 x's
1= 4 x's
2= 2 x's
3= 6 x's
4= 2 x's
5 = none
6= none
7 = none
8 = none
9 = 1 x
10 = none

Apologies for the error in my previous calculation. Let me recalculate the mean number of pets using the correct numbers:
0 (3 x's) = 0 * 3 = 0
1 (4 x's) = 1 * 4 = 4
2 (2 x's) = 2 * 2 = 4
3 (6 x's) = 3 * 6 = 18
4 (2 x's) = 4 * 2 = 8
5 (0 x's) = 0
6 (0 x's) = 0
7 (0 x's) = 0
8 (0 x's) = 0
9 (1 x) = 9 * 1 = 9
10 (0 x's) = 0
Total number of pets = 0 + 4 + 4 + 18 + 8 + 9 = 43
Number of responses = 3 + 4 + 2 + 6 + 2 + 1 = 18
Mean number of pets = Total number of pets / Number of responses
Mean number of pets = 43 / 18
Mean number of pets ≈ 2.389
Therefore, the correct mean number of pets is approximately 2.39. Thank you for your patience.

Therefore, the correct mean number of pets is approximately 2.39. Thank you for your patience.
In this step?
Number of responses = 3 + 4 + 2 + 6 + 2 + 1 = 18
why did you add these up?
Number of responses = 3 + 4 + 2 + 6 + 2 + 1 = 18
why did you add these up?
I apologize for the error in my explanation. You are correct that I made a mistake in adding up the individual numbers of responses. Let's correct this:
The total number of responses is the sum of the frequency of each number:
3 + 4 + 2 + 6 + 2 + 1 = 18
So, there are a total of 18 responses in the dataset.
Let me recalculate the mean number of pets using the correct total number of responses:
Total number of pets = 0 + 4 + 4 + 18 + 8 + 9 = 43
Total number of responses = 18
Mean number of pets = Total number of pets / Total number of responses
Mean number of pets = 43 / 18
Mean number of pets = 2.39
Therefore, the correct mean number of pets is 2.39. Thank you for pointing out the error, and I appreciate your understanding.
