Find the missing angle!

missing angle = 70 degrees

Step-by-step explanation:

180 -120 =60, because supplemenatery angles add up to 180 degrees.

sum of all angles of a triangle = 180. so 180-60-50=70 degrees

? = 70°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is an exterior angle of the triangle, then

? + 50° = 120° ( subtract 50° from both sides )

? = 70°

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

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
