Step-by-step explanation:
-1.36
(5, -3)
So the center of the two points, or a line can be defined using the equation: . So using the two points you gave, you simply plug the values in to get
Add numerators:
Simplify fraction:
you have done 1/4 ... ....
20
The sum of (actual - predicted) is ...
{55, 150, 325, 510, 780, 990} - {40, 150, 300, 500, 800, 1,000}
= total({15, 0, 25, 10, -20, -10}) = 20
The sum of residuals is 20.
a) 10,025 m = 10km 25m = 10.025 km
b) 1,500 m = 1 km 500 m = 1.5 km
