Using the line of best-fit, it is found that the residual for the player is of 12.6.
<h3>What is the residual for a line of best-fit?</h3>
A residual is given by the difference <u>between the observed point and the predicted point</u>.
In this problem, the expected score over x hours is given by:
f(x) = 280.3 + 85.7x.
Hence, for 3 hours, the predicted score is given by:
f(3) = 280.3 + 85.7 x 3 = 537.4.
The observed score was of 550, hence the residual is given by:
R = 550 - 537.4 = 12.6.

Answer:
It's A
Step-by-step explanation:
The days are 5, 7, and 30. 20kg of butter is used in a day.
20x5= <em>100</em>
20x7= <em>140</em>
20x30= <em>600</em>
Answer:
A and C are proportional relationships.
Step-by-step explanation:
Recall that a "proportional relationship" has no constant term. Thus, we eliminate Answers B and D immediately.
Answer A represents a proportional relationship: y varies directly with the square of x.
Answer C also represents a proportional relationship: y varies directly with x.
Answer:
the similarity statement helps you see that side RQ corresponds to UV, therefore 2x-4 : 5, and VW and QP are corresponding sides
Step-by-step explanation:
set up a proportion, then cross-multiply
2x-4/16 = 5/8
8(2x-4) = 16(5)
x = 7
The point-slope form of a line:
We have the points (-9, -5) and (2, -4). Substitute:
The standard form of a line:
<em>multiply both sides by 11</em>
<em>subtract 9 from both sides</em>
<em>subtract 11y from both sides</em>
