To find the mean number of pets, we need to add up all the numbers represented by the x's and then divide by the number of x's.
The numbers represented by the x's are 2, 4, 2, 4, and 0.
2 + 4 + 2 + 4 + 0 = 12
Now, we divide 12 by the number of x's, which is 5:
12 / 5 = 2.4
So, the mean number of pets is 2.4.
