Review the scatterplot shown. On a coordinate plane, points are around (1, 48), (2, 53), (5, 71), (9, 90).

When using the median-fit method to model the data in the scatterplot, which would be reasonable summary points?

(2, 53), (5, 70), and (7, 80)
(7, 80), (8, 85), and (9, 90)
(1, 47), (2, 53), and (3, 61)
(2, 60), (5, 80), and (8, 90)

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
