A line of best fit is a line drawn at average distance to a series of scattered points. Thus, the correct option is:
Option B. The <em>data</em> point is 4. 5 units <u>below</u> the line of best fit.
A graph is said to be formed by plotted points on a <u>Cartesian </u>coordinate plane. When the plotted <em>points</em> are <u>scattered</u>, a <em>line of best fit</em> is required to shoe the relationship among the plotted <em>points</em>.
A <u>residual</u> <u>value</u> is a form of error that is determined from the <em>line of best fit</em>. A <u>line of best fit</u> is a line drawn at <em>average</em> point to a <em>series</em> of plotted <em>scattered</em> points.
Therefore, a residual value of 4.5 with respect to a <em>line of best fit</em> implies that: The data point is 4. 5 units <u>below</u> the <em>line of best fit</em>.
Thus the <em>correct</em> option is B.

Answer:
2/45
Step-by-step explanation:
First chooses a polka dot shirt: 2 / (5+6+2+2) = 2/15
Then a striped shirt, after replace: 5/15 = 1/3
the probability that she chooses a polka dot shirt then a striped shirt:
2/15 x 1/3 = 2/45
Tina can finish in 5 hours
Bill takes two hours longer than Tina.
5+2=7
Bill takes 7 hours to cut the lawn.
7+5=12
It takes both of them working together 12 hours. Hope this helped!
