Three randomly chosen California students were asked how many times they drove to Mexico last year. Their replies were 4, 5, 6. The geometric mean is:

4.93

Step-by-step explanation:

Given 3 numbers a, b and c, the formula for calculating their geometric mean is expressed as:

GM = ∛a*b*c

Given the numbers 4, 5 and 6

geometric mean = ∛4 * 5 * 6

geometric mean = ∛20*6

geometric mean = ∛120

geometric mean = 4.93

Hence the geometric mean is 4.93

a: 1/6, j: 1/4

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
