To find the mean number of pets in the line plot, we first need to determine the numbers that each x represents. From the line plot, we can see that the numbers represented by the x's are: 2, 4, 2, 4, 2, 4, 2, 2, 2, 4, 2, 4, 2, 2, 2, 4, 2.

Adding all these numbers together, we get: 2+4+2+4+2+4+2+2+2+4+2+4+2+2+2+4+2 = 48.

There are a total of 17 x's in the line plot, so to find the mean number of pets, we divide the sum by 17: 48 / 17 = 2.82.

Therefore, the mean number of pets is 2.82.

My apologies for the confusion. Let's calculate the mean number of pets again using the correct values:

Given numbers represented by the x's in the line plot: 2, 4, 2, 4, 2, 4, 2, 2, 2, 4, 2, 4, 2, 2, 2, 4, 2

Adding all these numbers together: 2+4+2+4+2+4+2+2+2+4+2+4+2+2+2+4+2 = 48

There are 17 values in total.

Now, calculating the mean: 48 / 17 = 2.82

So, the mean number of pets is 2.82.

I hope this clarifies the calculation.
