The data in the table can be entered into a calculator to determine a linear equation of best fit where x represents the school year and y represents the cost of tuition, room, and board in dollars.
Average Annual Tuition, Room,
and Board at 4-year Universities
School Year, x Cost (S), y

What conclusion can be drawn from the correlation coefficient?

2

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
