To find the mean of the given values, we need to add them up and divide the result by the total number of values. So, the sum of the given values is: (t + 2) + (2t - 4) + (3t + 2) + 2t = 8t There are four values, so to find the mean, we divide the sum by 4: mean = (8t) / 4 = 2t Therefore, the correct option is 2t, which is the mean of the given values. To summarize, the mean of the values t + 2, 2t - 4, 3t + 2, and 2t is 2t. We added up the values and divided by the total number of values to find the mean.
