The following data indicate the numbers of accidents bus drivers had in one year as a function of the numbers of years on the job.
years on job(xi)= 2,4,6,8,10,12
accidents(yi)= 10,8,3,8,45

(a) fit these data with a regression model of the form ŷ= qx +r determine q and r by computing the pseudoinverse of x, the matrix whose first column is the vector of xi's and whose second column is a 1's vector.
(b) what is the condition number of the matrix (xtx)? is the problem poorly conditioned?
(c) repeat the calculations in part (a) by first shifting the x-values to make the average x-value be 0

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other

step-by-step explanation:

bobby has the most candy because 7/8= .875

step-by-step explanation:

the equation of the line that passes through the points and has o form

if line passes through the points (-1, -3) and (2, 1), then

the equation in the standard form is
