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:
<h3>13 years</h3>
Step-by-step explanation:
Let the present age of Alicia be x
Let the present age of her brother be y
Three years ago;
Alicia age = x - 3
Her brother's age = y - 3
If three years ago Alicia was twice as old as her brother Carlos, then;
X - 3 = 2(Y-3)
x-3 = 2y - 6
x = 2y - 3 ...1
In two years time;
Alicias age = x+2
Her brother's age = y +2
If in two more years Alicia will be just 50% older than Carlos, then;
x+2 = y + 2 + (0.5(y+2))
x+2 = y+2 + 0.5y + 1
x+2 = 1.5y+3
x = 1.5y + 1 ...2
Equating 1 and 2;
2y - 3 = 1.5y + 1
2y - 1.5y = 1+3
0.5y = 4
y = 4/0.5
y = 8
Since x = 2y-3
x = 2(8) - 3
x = 16-3
x = 13
Hence Alicia will be 13 years old today
