An insurance actuary tracks the customer mass and the dosage of a certain medicine prescribed to customers. An approximate least-squares regression line was used to predict the dosage, in milligrams,
from a given customer mass, in kilograms.

Interpret the residual for the customer indicated in the scatterplot above.

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

366

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
