Seven fish were caught the weights were 15, 16, 15, 13, 19, 20, and 21 what is the mean weight of these fish

17

Step-by-step explanation:

To find the mean of a data set, you add all of the values together, then divide by how many values there are in the set. Lets break this down into a few steps:

1: Add all of the numbers together

15+16+15+13+19+20+21 = 119

2:Divide that number by how many numbers are in the set

There are 7 numbers in this set, so 119:7=17

So the mean weight of the fish is 17

17

Step-by-step explanation:

Add all of them up to give 119

there are 7 fish so 119/7=17
