Answer:
See explanation
Step-by-step explanation:
The numbers are ordered from greatest to least.
The numbers are: 582, 478, ?, 326, 201.
The missing number is between 478 and 326.
Therefore all the following are possible solutions.
400
420
330
458
In fact any number greater than 326 but less than 478 is correct
Is this a relation: {(-2,1), (0,0), (0,1), (1,-2), (1,0), (1,3), (2,0)}? Explain why or why not.

It is a relation because any relation is simply a set of (x,y) values known as points or ordered pairs. There are no other qualifications needed to be a relation. We simply pair up any x and y value we want.
I think you meant to ask if it's a function or not. If so, then the answer is "no, it is not a function". Why not? Because the x value x = 0 produces more than one y output y = 1 and y = -2. Graph these points and you'll see them fail the vertical line test (ie its possible to draw a vertical line through more than one point on the graph). The same issue happens with (1,-2), (1,0) and (1,3) as well.
In summary:
Yes it is a relation
No it is not a function
The reasoning for each is stated above
The mean of the numbers is 11 now all you have to do is take 11 and subtract it from the squared difference.
