1. for the data in the table, does y vary directly with x? if it does, write an equation for the direct variation. x y 8 13 16 26 24 39 (1 point) yes; y = 5x yes; y = 10x yes; y = 1.625x no; y does not vary directly with x. 2. for the data in the table, does y vary directly with x? if it does, write an equation for the direct variation. x y 40 32 28 16 16 12 (1 point) yes; y = 2x yes; y = 0.5x yes; y = 1.5x no; y does not vary directly with x.

anyine know the rest of the test anwers

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). =
