For middle school practice, a pitching machine is set to throw a baseball 50 miles per hour at 25° north of east. For high school, the only setting change for the machine is to have it throw at 75 miles per hour. Complete the statements about the vectors that represent the different settings on the machine. To find the vector representing the high school setting, multiply the vector representing the middle school setting by a scalar that is

.

Compared to the vector for the middle school setting, the vector representing the high school speed is

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). =
