If an x intercept only touches the x axis it means it has a multiplicity of 2. if an intercept goes through the axis it has a multiplicity of 1 true false

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

Collin did the work to see if 10 is a solution to the equation r/4=2.4
