The data below represent commute times (in minutes) and scores on a well-being survey. complete parts (a) through (d) below. commute time (minutes), x 5 15 30 40 60 84 105 well-being index score, y 69.1 68.0 66.8 66.1 64.9 64.1 62.0 (a) find the least-squares regression line treating the commute time, x, as the explanatory variable and the index score, y, as the response variable.

answer: 19 is   2

step-by-step explanation: i just looked at your answer and wrote it down

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
