Suppose that a random variable x has a discrete distribution with the following probability mass function: f(x) = ( cx if x = 1, 2, 3, 4, 5 0, otherwise determine the value of the constant c.

F(n + 1) = f(n) – 8. if f(1) = 100, what is f(6)?

The fraction 7/9 is equivalent to a percent that is greater than 100%. truefalse

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done
