We want to find the mean of two elements in a set, given that we know the other elements of the set and the mean of the whole set.
The answer is: -490
-----------------------------
For a set with N elements {x₁, x₂, ..., xₙ} the mean is given by:

Here we know that:
- The mean of the set is 0.
- The set has 1000 elements.
- 998 of these elements are ones, the other two are A and B.
We want to find the mean of the values of A and B.
First, we can start by writing the equation for the mean:

We can rewrite this as:

And we have 998 ones, then:

Now we have B isolated.
With this, the mean of A and B can be written as:

So we can conclude that the mean of the other two numbers is -490.

Answer:
dude use the order of operations the square root the thing
PLEASE MARK ME AS BRAINLIST
The median is the number in the middle of the data set.
There are 7 numbers, so the 4th number is the median.
(Another method is to eliminate a number on each side until you get to the middle number)
<h2>Answer:</h2>
<u>The median is </u><u>16</u><u>.</u>
