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 4.78
To find the mean number of pets, we add up all the numbers and then divide by the total number of responses.
2.39 + 2.39 + 4.3 + 4.3 + 2.87 + 2.87 + 4.78 + 4.78 = 24.28
Now we divide by the total number of responses:
24.28 / 8 = 3.035
So, the mean number of pets is 3.035.
