How do you find the mean of the following set of numbers: 12, 14, 16, 12, 13?

Answer 1

The mean is #13.4#

the mean #barx=(sumx_i)/n# So applying this formula #barx=(12+14+16+12+13)/5=13.4# You can also do #barx=12 +(2+4+1)/5=12+7/5=12+1.4=13.4#

To find the mean (average) of a set of numbers, you add up all the numbers in the set and then divide the sum by the total number of values in the set.

For the set of numbers 12, 14, 16, 12, and 13, the calculation would be:

(12 + 14 + 16 + 12 + 13) / 5

= (67) / 5

= 13.4

So, the mean of the given set of numbers is 13.4.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
