bь?
which statement best explains
why the sum of the areas of the
two white squares in figure 2 is
the same as the area of the white
square in figure 1?
aь
figure 1
figure 2
in each triangle, the length of side a plus the length of side b equals the length
of side c. that means that a? + b2 = c.
the combined area of the four triangles is equal to the area of the large white
square.
in each figure the total area is equal and the area of the 4 triangles is equal, so
the remaining white area in each figure must also be equal.

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). =
