Solve for the indicated information. solve for x.

-9

Step-by-step explanation:

x + 109 + x + 89 = 180° because these angles are supplementary

2x + 198 = 180 subtract 198 from both sides

2x = - 18 divide by 2

x = -9

answer: huh

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
