SolutionConsider the table: a) Sum(x) = 1 [answer] b) Sum(x^2) = 39 [answer] c")
Solution
Consider the table:
a)
Sum(x) = 1 [answer]
b)
Sum(x^2) = 39 [answer]
c)
Sum(x^2) - Sum(x)^2/5 = 39 - 1^2/5 = 38.8 [answer]
| x | x^2 | |
| 5 | 25 | |
| 0 | 0 | |
| -3 | 9 | |
| -2 | 4 | |
| 1 | 1 | |
| Totals | 1 | 39 |
