Which equation can be used to find the unknown length, b, in this triangle?
A right triangle has a side with length 4 inches and hypotenuse with length 5 inches. The other side is labeled b.
4 squared + b squared = 5 squared
4 squared minus b squared = 5 squared
5 squared + 4 squared = b squared
5 squared + b squared = 4 squared

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). =
