Regression analysis was applied between $ sales (y) and $ advertising (x) across all the branches of a major international corpo
ration. The following regression function was obtained.y= 5000 + 7.25xIf the advertising budgets of two branches of the corporation differ by $30,000, then what will be the predicted difference in their sales?a. $217,500b. $222,500c. $5000d. $7.25
I can use the Distance Formula<span> to find the lengths of the each of the sides of the triangle, these lengths being the distances between the pairs of points. Then I can plus these distances into the Theorem to see if this triangle is a right triangle</span>
The forward differences for this data is 1, 1, 1, 1, 1, 1 (since 10 - 9 = 1, 11 - 10 = 1, etc). Since we only need one iteration of differences, a linear polynomial will fit the data exactly.
