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.
0, 1, 1, 1, 2, 2, 2, 3, 4, 4
Calculating the mean:
0 + 1 + 1 + 1 + 2 + 2 + 2 + 3 + 4 + 4 = 20
20 ÷ 10 = 2
The mean number of pets is 2.
2.39
4.3
2.87
4.78
To find the mean number of pets from the given list of numbers, we add them up and divide by the total count:
2.39 + 4.3 + 2.87 + 4.78 = 14.34
Total count = 4
Mean = 14.34 / 4 = 3.585
Therefore, the mean number of pets is 3.585.
