Two circles are concentric if they have the same center
which equation represents a circle that is concentric with
the circle shown but has a radius that is twice as large?
0.(x – 4)2 + (-6)2 = 4
(x-4)2 + (-6)2 = 16
o (x – 6)2 + (1 – 4)2 = 16
(x - 6)2 + (y – 4)2 = 4

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). =
