A sixth number will be added to this list: 7,16,11,12,10 what must the number be for the mean to be 12
To find out what the sixth number should be in order to get a mean of 12, you need to use the formula for finding the mean:
mean = (sum of all the numbers) / (total number of numbers)
In this case, you have five numbers and you want the mean to be 12. So you can set up the equation:
12 = (7 + 16 + 11 + 12 + 10 + x) / 6
Simplifying this equation, you get:
72 = 56 + x
Subtracting 56 from both sides, you get:
16 = x
So the sixth number should be 16 in order to get a mean of 12.
