The following data are from the test of a water-pumping windmill: (15 points) Vwind(m/sec) Q(l/s) 4 0.94 5 1.69 6 2.44 7 3.08 8 3.72 a. Plot these data b. Fit a linear regression to the data c. Fit a second degree polynomial to the data Which do you think is the better regression function

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

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.
