Step-by-step explanation:
- The probability distribution provides the probabilities of occurrence of different possible outcomes, in this case we want to know what is the probability that the variable X takes any value between 9 and 18.
- The probability of occurrence is shown in the vertical axis of the graph. We want to know what is the probability of finding values of X between 9 and 18, then we should add up the probabilities between these two values , which means adding

Answer:
11
Step-by-step explanation:
5x° + 35° = 90°
(complementary angles)
5x° = 90° - 35°
5x° = 55°
x = 55/5
x = 11
