Answer:
1. what is a residual?
A. A residual is a value of y -y, which is the difference between an observed value of y and a predicted value of y.
2. The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.
Step-by-step explanation:

2. In what sense is the regression line the straight line that "best" fits the points in a scatterplot?
The regression line has the property that the_sum of squares_of the residuals is the minimum possible sum.
Equation to find number:
- 3 = 
Number's value: n = 
Step-by-step explanation:
Let n be the unknown number.
The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be
.
The difference of three and the reciprocal of a number (
) would be
- 3.
The quotient of 20 and the number (n) would be
.
So, with this information we've gathered so far, we can come up with an equation to find what the number equals.
Equation:
- 3 = 
To find what the number equals we must solve the equation.
