In a manufacturing process the assembly line speed (feet per minute) was thought to affect the number of defective parts found during the inspection process. To test this theory, the same batch of parts was inspected visually at a variety of speeds. The following charts show the collected data, their scatterplot and the least squares fitted line.

Line Speed Number of defective parts found20 2120 1940 1530 1660 1440 17a. Develop the estimated regression equation that relates line speed to the number of defective parts found.

answer: i feel you honey.

step-by-step explanation:

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
