Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms.
2 similar right triangles. Triangle 1 has side length 8, hypotenuse 10, and blank side. Triangle 2 has side length 4, hypotenuse 5, and blank side.
a.
StartFraction 4 Over 10 EndFraction = StartFraction 5 Over 8 EndFraction = two-fifths
b.
StartFraction 4 Over 8 EndFraction = StartFraction 5 Over 10 EndFraction = one-half
c.
StartFraction 10 Over 4 EndFraction = StartFraction 8 Over 5 EndFraction = Five-halves
d.
StartFraction 4 Over 5 EndFraction = StartFraction 8 Over 10 EndFraction = four-fifths

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). =
