The route that a trolley takes around a city can be represented by the functions x2 + y2 = 10. A train track's path can be described by the function x + y = 4. At which location(s) will the trolley and train meet?

A) (–1, 3) and (–3, –1)
B) (3, 1) and (–3, –1)
C) (1, 3) and (3, 1)
D) (–3, 1) and (1, 3)

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). =
