Answer:
45
Step-by-step explanation:
The mean, or average of a data set is the sum of all elements of a set divided by how many elements there are. In this case, the mean is (40+41+42+43+44+45+46+47+48+49+50)/11. We divide by 11 because there are 11 numbers. When we simplify this, we get 495/11 = 45. Hope this helps!
