To find the mean number of pets, we first need to total the number of pets and then divide by the total number of responses.
0 (3 times) + 1 (4 times) + 2 (2 times) + 3 (6 times) + 4 (2 times) + 9 (1 time) = 0*3 + 1*4 + 2*2 + 3*6 + 4*2 + 9*1 = 0 + 4 + 4 + 18 + 8 + 9 = 43
Now, let's divide the total number of pets by the total number of responses:
43 (total number of pets) / 18 (total number of responses) = 2.39
So, the mean number of pets is 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!
