Use r = 2 and r = 5 to determine if the two expressions are equivalent.
r+ 4(2 + r) - 12 8 + 2r - 6
Complete the statements.
When r = 2, the first expression is

When r = 5, the second expression is

The expressions are not equivalent.

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). =
