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.

How do you work out the median for a set of eight numbers?
Arrange the numbers in ascending order, and then take the mean of the fourth and fifth number.
The mean of four numbers is 30. If three of the numbers are 12 50 and 48 what is the fourth 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
What is the median of a set of 6 numbers?
If you order the numbers by size, it is the mean of the third and fourth numbers. Median = (N3 + N4)/2
Mean of a set of number?
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 the mean is 4 what is the missing number 3 2 7?
Mean = 4 so sum = 4*4 = 16 The sum of the three numbers is 12 so the fourth is 16-12 = 4.

what is the fourth number if the three numbers are 80,95, and 85 if the mean is 88?
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.
How do you find the average of four numbers when the fourth is unknown?
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.
What is the whole number for 0.25?
