1) the following is a relation (-2d) for which ordered pair (c, d) is the relation a function?

a) (-3,5)
b) (-2,8)
c) (1,-8)
d) (3,4)

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

50 points~ ! i have to turn this in tomarrow

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). =
