FIND THE VALUE OF X! WILL MARK BRAINLIEST IF CORRECT!

x = 60°

Step-by-step explanation:

      A circle, or "all the way around," is 360°

      The square represents 90°

360° = 90° + (2x - 10)° + (2x + 40)°

360° = 90° + 2x° - 10° + 2x° + 40°

360° = 2x°+ 2x° + 40° + 90° - 10°

360° = 4x° + 120°

240° = 4x°

60° = x

x = 60°

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
