Follow the steps below to find the mean for the set of data. use the work shown to you. data set: 6, 5, 8, 5, 9, 6, 7, 5, 12 first add the values. 6 + 5 + 8 + 5 + 9 + 6 + 7 + 5 + 12 = 63 then divide by the number of values. there are 9 values. what is the mean of the data set? 5 6 7 8

What expression is equivalent to 1/2(2+3x-6)
