14.what value of n will result in a mean if 31

15.what value of n will result in a median of 23
15.what value of a will result in a range of 84

14,46,19,10,39,22,24,77,n

Refresh your memory about the defnition of median, mode and range of a set of numbers.
Then pick a value of n that satisfied the requirement.

For example, in #14. Find the value of n that makes the average 31. You should end up with the equation
(251+n)/9 = 31
Then solve for n. You divide by 9 because there are 9 numbers and you want the average or "mean" value.

To find the value of n that will result in a mean of 31 in the given set of numbers (14, 46, 19, 10, 39, 22, 24, 77, n), we need to calculate the sum of all the numbers and divide it by the total count of numbers (including n).

The sum of the given numbers is 14 + 46 + 19 + 10 + 39 + 22 + 24 + 77 = 251.

Now, we can set up the equation to find the value of n:

(251 + n) / 9 = 31

To isolate n, we start by multiplying both sides of the equation by 9:

251 + n = 31 * 9

Simplifying, we have:

251 + n = 279

Next, we isolate n by subtracting 251 from both sides of the equation:

n = 279 - 251

n = 28

Therefore, the value of n that will result in a mean of 31 in the given set of numbers is 28.
