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.
11 increased by 12 is the same as 11 plus 12 so the answer is 23
No, for example the set of data 15,20,26,28 has a median that is 20 + 26 /, or 23
-11 + -12
(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12
12 is greater than 11 by a difference of 1. In mathematical terms, the comparison can be expressed as 12 - 11 = 1. This means that 12 is one unit larger than 11 on the number line.
12 + 23 + 14 + 11 = 60/4 = 15 The average is therefore 15.
12
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 = 23 - 11 6y = 12 y = 12/6 y = 2.
12 + 11 = 23
23
23
11 increased by 12 is the same as 11 plus 12 so the answer is 23
23
The atomic number of sodium is 11 so it has 11 protons. For Na-23 there are 12 neutrons (23 - 11 = 12)
23
23/12 = 1 11/12 23/8 = 2 7/8 = 2.875
