(-12 + (-4) + 3+7+11) = 5/5=1

Answer=1

Hi there! To find the mean we add up all of the data and then divide by how many numbers there are. In this case we have the numbers of - 12, - 4, 3, 7, and 11. - 12+-4+3+7+11=5. Now, we divide by how many numbers there are. In this case we have 5 numbers of data. 5 divided by 5 equals 1. Therefore, the mean of the set of numbers is 1.
