The mean is 12. First, I added all the numbers together. 16+14+15+8+16+3. The sum is 72. Then, I divided the sum by the amount of numbers. 72/6=12. The final answer is 12.
THE LCM OF 3 8 12 15 is 120.
8 and 5/15 - 3 and 8/15 = 4 and 12/15 = 4 and 4/5
8a - 15 = -3 8a = 15 - 3 8a = 12 a = 12/8 = 6/4 = 3/2
Mean = (sum of the samples) divided by (number of samples) = (8 + 12 + 15 + 11) / 4 = 46/4 = 11.5
