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. 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.
the missing value will be -36 because if you multiplied it with 4 you will only have to add another -4 to get -144
Answer:
55.55%= boys & 44.44% = girl
Step-by-step explanation:
1000/(1000+800)=1000/1800=.5555 or 55.55% are boys
800/(1000+800)=800/1800=.4444 or 44.44% are girls.
Therefore, 55,55% are boys and 44.44% are girls.
Answer:
x = first piece
14 - x = second piece
Step-by-step explanation:
Since we know that the board is 14 feet then to find the size of the second piece, we just take the full length of the board and then subtract it to the first piece's length.
