The predicted values were computed by using the line of best fit, y = 3.2x + 2.

A 4-column table with 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled given with entries 16.1, 7.4, 11, 15. The third column is labeled predicted with entries 5.2, 8.4, 11.6, 14.8. The fourth column is labeled residual with entries a, b, c, d.

What are the residual values needed to complete the chart?

A= 0.9

B= -1

C= -0.6

D= 0.2

A. 0.9

B. -1

C. -0.6

D. 0.2

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
