Select all of the following for which there exist nonzero constants which can be substituted into the equation to make it true.
a) a/(x-2)(x+7)=b/(x-2)

b) a/(x-2)(x+7)=b/(x-2)+c/(x+7)

c) a/(x-2)(x+7)=b/(x-2)+c/(x+7)+6

d) none of the above?

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
