Hello!
The residual for the point (5,1) is
To calculate residuals, we need to calculate the value of the line of best fit in the same x coordinate as the point we want to study to know the Predicted-y-value. To do so, we make the substitution of 5 into the equation:

Now we determine the residual with the following equation:

Have a nice day!
Answer:
The equation for the cost in dollars of producing computer chips
The equation for the cost in dollars of producing computer chips is C = 0.000015x^2 - 0.03x + 35, where x is the number of chips produce. Find the number of chips that minimizes the cost.
