For a sample of similar sized all-electric homes, the march electric bills were (to the nearest dollar): $212, $191, $176, $129, $106, $92, $108, $109, $103, $121, $175, and $194. what is the range? $112 $100 $130 $120

The range of the given data is $120.

Step-by-step explanation:

For a set of observations, we know that the range of the set is given by:-

In the given data , the largest data value= $212

The smallest value= $92

Therefore, the range of the given observations is given by:-

Hence, the range of the given data is $120.

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
