Answer:
398.21 m
Step-by-step explanation:
The field inside a running track is made of a rectangle that is 84.39 m long and 73 m wide to gather with a half circle at each end.
So, the radius of each half circle will be 
m.
Therefore, the total distance around the track i.e perimeter of the area covered by the track will be = 2 × Perimeter of each half circle + 2 × Length of the rectangle.
= Perimeter of full circle + 2 × Length of the rectangle.
= 
= 
= 398.21 m.(Answer)

Answer:
d. always zero.
Step-by-step explanation:
A least squares regression line is a standard technique in regression analysis used to make the vertical distance obtained from the data points running to the regression line to become very minimal or as small as possible.
For a least squares regression line, the sum of the residuals is always zero.
Basically, residuals are used to measure or determine whether or not the line of regression is a good fit or match for the data by subtracting the difference between them i.e the predicted y value and the actual y value, for the x value respectively.
