Question

Calculate the mean of 12, 15, 6, 4, and 3. 2 8 12 40

Answer 1

Answer:

For 12, 15, 6, and 4 the mean would be 9.3.

For 2, 8, 12, and 40 the mean would be 15.5

If you combine them, 12, 15, 6, 4, 2, 8, 12, and 40 the mean would be 12.4

Step-by-step explanation:

You can find out the mean by adding up all the numbers and then dividing them by the total amount of numbers:

Example(s): 12+15+6+4=37 and 37 / 4 = 9.25, but you would round up, so your answer would be 9.3

2+8+12+40=62 and 62 / 4 = 15.5.

Hope this helps!
