Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point. No solution.

Answer:
Let me see what i can do, I'll try. Hope this helps
Answer is C.
Explanation:
So we have 100 data, aka numbers. So the mean would be
where bunch of x represents those data.
So then
, right?
So we have six outliers with mean 688. That would be
So then
Now we don't know what i₁, i₂, etc, but we can just subtract outliers from set of observations and we will know that outliers will be gone in set of observation.
So that would be
Now we know that there are now 94 remaining observations. So to find mean, we just divide whole thing by 94.
Which matches C.
Hope this helps.
