to find mean of four numbers, you would take the four numbers and add them. Then you would divide them by four. Now, if you want a mean of 80, just reverse the process. take the mean you want and multiply by four. Then just find four numbers that add up to the number you just got. For example if you wanted 3 numbers that have a mean of 110, you would take 110 and multiply it by 3 to get 330. Then you would find three numbers that add to 330 to get your answer. So the answer to my sample could be the numbers 1, 1, and 328 because they add to 330. A possible answer to your question would be 1, 1, 1, and 317 because if you add them up and divide by four, you would have 317+1+1+1=320. Then 320/4=80. So a possible answer could be 317, 1, 1, and 1.

What is the average of 60 70 80 110?
80 is. ------------------------------------------- The mean average is calculated by adding up the numbers and dividing by how many there are: mean average = (80 + 60 + 70 + 110) ÷ 4 = 320 ÷ 4 = 80
How do you find the mean of a group of numbers?
you add all of the numbers in the group together and then divide the number you get by how many numbers are in the group EX: your group is 21, 32, 12, 15. you add 21+32+12+15= 80. then you divide 80 by 4 because you have four numbers in your group. so your mean is 20!
What to numbers can you multiply to get -80 but add to get -16?
-96
What is the mean of 60 72 80 80 and 98?
78. add up all the numbers and then divide by the number of numbers you added.
What numbers between 61 and 107 are multiples of 4 5 and 10?
It is: 80 and 100
Math term mean?
mean is the average for example. if u have the numbers 26 14 32 and 8 you add the numbers together and you get 80. then you divide 80 by 4 because there are 4 numbers in the group. so your answer would be 20.
What is the average of 60 70 80 110?
80 is. ------------------------------------------- The mean average is calculated by adding up the numbers and dividing by how many there are: mean average = (80 + 60 + 70 + 110) ÷ 4 = 320 ÷ 4 = 80
How do you find the average for 100 70 80 90?
Sum them : 340 Count them: 4 numbers Divide sum by number of numbers = 340/4 = 85. Alternatively, in this case, you may notice that the numbers are evenly spaced. The middle two numbers are 80 and 90 so halfway between then will be the overall mean. This only works for the arithmetic mean of evenly spaced numbers.
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.
What set of numbers has a mean of 80?
There are an infinite number of sets with mean 80. Here are some: {80, 80, 80}, {80, 80, 80, 80, 80, 80} {79, 80, 81}, {79, 79, 80, 81, 81}, {79, 79, 80, 82} (1, 80, 159}, {-40, 200} To produce a set of n numbers with mean 80, start with any set of n-1 numbers. Suppose their sum is S. Then add the number 80*n-S to the set. You will now have n numbers whose sum is S+80*n-S = 80*n So the mean of this set is 80.
How do you find the mean of a group of numbers?
you add all of the numbers in the group together and then divide the number you get by how many numbers are in the group EX: your group is 21, 32, 12, 15. you add 21+32+12+15= 80. then you divide 80 by 4 because you have four numbers in your group. so your mean is 20!
What numbers go into 80 and 4?
They are: 1, 2 and 4
What to numbers can you multiply to get -80 but add to get -16?
-96
Mean is 40 and gm is 60 find out value of two numbers?
For real numbers the geometric mean is always less than the arithmetic mean, so the answer must involve complex numbers. x + y = 80 x * y = 3600 x * (80 - x) =3600 x^2 - 80x +3600 = 0 x = 0.5 * (80 +/- sqrt(80^2 - 4 * 3600)) = 40 +/- sqrt(40^2 - 3600) = 40 +/- sqrt(2000) = 40 +/- 10 * sqrt(20) so the two numbers must be imaginary and are: 10 * (4 + i * sqrt(20)) and 10 * (4 - i * sqrt(20))
What three numbers do you times to get 80?
