The geometric mean is often used in business and economics for finding average rates of change, average rates of growth, or average ratios. given n values (all of which are positive), the geometric mean is the nth root of their product. the average growth factor for money compounded at annual interest rates of 8.5%, 4.1%, and 2.7% can be found by computing the geometric mean of 1.085, 1.041, and 1.027. find that average growth factor, or geometric mean. what single percentage growth would be the same as having three successive growth rates of 8.5%, 4.1%, and 2.7%? is that result the same as the mean of 8.5%, 4.1%, and 2.7%?

(a) Average growth factor =

                                           =

                                           =  

                                           = 1.05068

(b) Single percentage growth rate = (Average growth factor - 1) × 100

                                                         = (1.05068 - 1) × 100

                                                         = 5.068 %

(c) The mean of 8.5%, 4.1% and 2.7% =

                                                             = 5.1%

Therefore, the single percentage growth rate is not the same as the mean of 8.5%, 4.1%, and 2.7%.

the answer is . a novel has no sub-plot, but a novella does

rational decision making is a multi-step process for making choices between alternatives. the process of rational decision making favors logic, objectivity, and analysis over subjectivity and insight. the word “rational” in this context does not mean sane or clear-headed as it does in the colloquial sense.
