A ball is thrown into the air with an initial velocity of 25 meters per second. The function h(t) = -4.9t2 + 25t + 6 represents the height of the ball above the ground in meters, with respect to time, t, in seconds. Part A: At h(3), then the height of the ball would be?
Part B: The graph below represents the height of the ball with respect to time.

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). =
