Let the fourth number be x. We have:
(80 + x)/4 = 88 (multiply both sides by 4)
80 + x = 352 (subtract 88 to both sides)
x = 272
Thus, the fourth number is 272.
Arrange the numbers in ascending order, and then take the mean of the fourth and fifth number.
The fourth number is 10. The sum of the four numbers is: 12 + 50 + 48 + fourth_number = fourth_number + 110 Mean = sum_of_numbers / how_many_numbers → sum_of_numbers = mean × how_many_numbers = 30 × 4 = 120 But from above: sum = fourth_number + 110 = 120 → fourth_number = 120 - 110 = 10
Mean is the same as average. To get the mean of a set of numbers: First, you add up all the numbers. Second, you divide by the number of numbers in the set. Total of all the numbers/Number of numbers in the set
If you order the numbers by size, it is the mean of the third and fourth numbers. Median = (N3 + N4)/2
Mean = 4 so sum = 4*4 = 16 The sum of the three numbers is 12 so the fourth is 16-12 = 4.
the mean of four numbers is 25 and three of the numbers are 17 23 and 25 what is the fourth number?
It is 10.

The three numbers are 80,95,85 Let the fourth number be x. Now the mean is 88 That is (80+95+85+x) /4=88 i. e. 260+x=88×4 i. e. 260+x=352 i. e. x=352-260=92 So fourth number is 92.
If that is what you mean, then you have 3 numbers, not 4, and you can't find an average when the unknown number could be any number. Basically, you have one equation with 2 unknowns and that can't be solved.

.25 doesn't represent a whole number. It is a rational number equivalent to one fourth (1/4). If you mean how do you represent .25 as the QUOTIENT of two whole numbers then the answer is 1/4.
The mean of a number is the average of a group of numbers. To find the mean you must add up all of the numbers in a data set. Then you take that number and divide it by the number of numbers you have in the data set. This will give you the mean.
