A number is called the break-even point if it is equal
to the sum of all other numbers under consideration. Assume that
|S| = 10 and that the Mean(S) = 1000. If one of the numbers in S is
a break-even point, what must be its value?
Your answer can only consist of digits (and if a real number, then
also decimal point) and no other characters, punctuation, letters
or spaces.
|S| =10
Mean(S) = 1000
