hloe finds a secret stash of 20 doggie treats with the following flavors: 7 beef, 7 chicken, 6 pork. She randomly selects 5 of them, but does not eat them (yet). (a) (8 points) If Chloe does not replace treats after she chooses them, let X be a random variable representing the number of chicken treats selected. Evaluate P [X

yes

step-by-step explanation:

yes

47 - 90 = 43

43 - 180 = x

x = 137

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.

your answer   is c
