The dot plot shows the ages of the members in a club. Select from the drop-down menus to correctly complete the statement.

If the youngest member leaves the club, the mean age of the club members would [increase/decrease/stay the same], but the median age would [increase/decrease/stay the same].

Mean would increase

Median would stay the same

Step-by-step explanation:

The mean would increase because the lowest number would not make the mean lower

The median would stay the same because there are three numbers with the value of 48, which is the median, and if 45 is gone, it would stay the same

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
