In a test of a particular weight loss program, welghts of 40 subjects are recorded before and after the program. the before -and-after weights result in a correlation coefficient of 0.876. assuming a 0.05 significance level, find the critical valuesis there sufficient evidence to support the claim of a linear correlation between before -and- after weights ?

darn right!

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.
