Mean is a fancy word for "Average". To calculate an average of a set of numbers you must add together the set of numbers and divide by the amount of numbers in the set. Let's solve your problem.
4, 12, 23, 11, 5. Remember the first step is to add all the numbers together.
4 + 12 + 23 + 11 + 5 = 55.
Now we need to do step two - which is to divide by the amount of numbers in the set. In this case we added together 5 numbers.
55/5 = 11.
So the Average of {4,12,23,11,5} = 11.

Increase 11 by 12?
11 increased by 12 is the same as 11 plus 12 so the answer is 23
If the mean of a set of data is 23 must 23 be one of the data values?
No, for example the set of data 15,20,26,28 has a median that is 20 + 26 /, or 23
What is 12 greater than 11?
23
What are the two consecutive integers of -23?
-11 + -12
What two numbers multiply to negative 12 and add up to negative 11?
23
What is the mean of 12 23 14 and 11?
12 + 23 + 14 + 11 = 60/4 = 15 The average is therefore 15.
What is 11 23 plus 11 23?
12
What is the range of 11 15 17 21 23?
The range is the difference between the maximum and minimum observation in a set of data. Thus the range is 12 (23 - 11).
6y+11=23?
6y + 11 = 23 6y = 23 - 11 6y = 12 y = 12/6 y = 2.
What is 12 plus 11?
12 + 11 = 23
What is 11-(-12) equal?
23
What is 12 add 11?
23
What is the atomic number of Na 23?
atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
Increase 11 by 12?
11 increased by 12 is the same as 11 plus 12 so the answer is 23
If the mean of a set of data is 23 must 23 be one of the data values?
No, for example the set of data 15,20,26,28 has a median that is 20 + 26 /, or 23
What is the sum of 12 11?
23
How many protons and neutrons are in sodium?
The atomic number of sodium is 11 so it has 11 protons. For Na-23 there are 12 neutrons (23 - 11 = 12)
