A rock climber averages 1235 feet per minute. Write and solve an equation to find how many feet x the rock climber climbs in 30 minutes. An equation is

What is the quadric regression equation that fits these data

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

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). =
