Answer:
Roughly 5.6
Explanation:
In able to find a mean in mathematics, we must add all the numbers together:
5.7 + 4.4 + 7.9 = 17
The next step is to divide the number we got by adding by how many numbers we had to begin with. Which in this case its three, so:
17 divided by 3 = 5.6666 (continues endlessly)
Definition of mean-- Average between multiple numbers.
