(X+60)(x+2) is the answer
Answer: Our required linear equation would be 
Step-by-step explanation:
Since we have given that
Number of cups = 150
Cost = $20
Number of cups = 400
Cost = $45
Let x be the number of cups, y be the cost .
We will use "Equation of line using Two point slope":

Hence, our required linear equation would be 
Combine 3, 5, 9. then combine 4, 2, and 2.
Answer:
<em>Predicted height: 57.42 inches</em>
<em>Residual: 2.58 inches</em>
Step-by-step explanation:
<u>Regression Equation</u>
The regression equation for the height of the children (Hgt) and their age (Age) is given by the expression
Hgt = 24.3 + 2.76(Age)
We must compare the predicted value of the equation vs the real data point Age=12, Height=60
Computing the predicted height
Hgt = 24.3 + 2.76(12)
Hgt=57.42 inches
The residual is the difference between the real data point and the predicted value
R=60-57.42
R=2.58 inches
