◉ Data point (10, 10); Residual = 4.50_____
Apparently, this question makes no use of the line of best fit.
The answer would simplify to 1/6.
Answer:
$6
Step-by-step explanation:
Susan can easily figure the tip by the following procedure. 10% of the bill is the amount with the decimal point moved one place to the left, so is $4.00. 5% of the bill is half that, or $2.00.
15% of the bill is 10% + 5%, so is $4.00 +2.00 = $6.00. The tip will be $6.00.
To find the mid point you must
x = (x1 + x2) / 2
y = (y1 + y2) / 2
(3,2.5)
