Two angles are complementary if the sum of their measures is 90 degrees . if the measure of an angle is 7 x degrees, represent the measure of its complement as an algebraic expression in x.

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable
