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


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 does it mean that answer correct to 4 decimal places?

It means to round the number to the nearest four decimal places (0.0000) for example the number 12.3476589 would be 12.3477 . The four decimal places are the amount of numbers after the decimal dot. For the fourth number after the decimal point, if the number after it is 5 or higher, than you round up to the next decimal number. If it is below five, you leave it as it is. If the fourth number is nine and the next one is eight for example, you also rise the third number as well as the fourth.

The mean of 4 numbers is 88The sum of 3 of the numbers is 80 what is the fourth number?

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.


The mean of 4 consecutive numbers is 9.5 What is the fourth number?

Suppose the four numbers are x, x+1, x+2 and x+3 Then their sum is 4x + 6 so that their mean is (4x+6)/4 = x + 6/4 = x+1.5 So x+1.5 = 9.5 so that x=8 and so the largest number is x+3 = 8+3 = 11. This answer assumes that the 4 consecutive numbers are in increasing order. If they were four consecutive numbers in decreasing order, they would be x, x-1, x-2 and x-3. In this case x=11 and the fourth number would be 8.


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.
