Geometric Mean

  1. Jun 19, 2005 #1
    I don't know why I can't figure this one out tonight. I just can't think straight and I am hoping someone can help ASAP.

    Here is the question:
    In 1998 revenue from gambling was $651 million. In 2001 the revenue increased to $2.4 billion. What is the geometric mean annual increase for the period?

    Since the difference in the number of years is 3, you have to take the cube root of the ratio to get your result.
