A particular professor has noticed that the number of people, P, who complain about his attitude is dependent on the number of cups of coffee, n, he drinks. From eight days of tracking he compiled the following data: People (P) 13 13 11 10 10 8 7 6
Cups of coffee (n) 1 1 2 2 3 3 4 5

Required:
a. Using regression to find a linear equation for P(n)

P(n)=
b. Find the correlation coefficient

answer: f = 32.2m

step-by-step explanation: that is the answer

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
