Three x's on 0, 4 x's on 1, 2 x's on 2, 6 x's on three, 2 x's on 4, 5 6 7 8 have no x's, 1 x's on 9, and no x's on 10
Number line 0 1 2 3 4 5 6 7 8 9 10
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! (1 point) Responses 2.39 2.39 4.3 4.3 2.87 2.87 4.78
The numbers represented by the x's are: 0, 1, 1, 2, 2, 3, 3, 3, 3, 3, 3, 4, 4, 9.
Adding them together: 0 + 1 + 1 + 2 + 2 + 3 + 3 + 3 + 3 + 3 + 3 + 4 + 4 + 9 = 41
Dividing by the total number of x's (25): 41 / 25 = 1.64
Therefore, the mean number of pets is 1.64.
