Thirty-two people woro choson at random from employoos of a large company. Their commute times in hours) were recorded in a tablo (shown on the right),
04 0.8 0.3 0.5 0.6 1.4 1.0 0.6
0.7 0.5 0.9 1.0 08 02 05 1.1
0.8 1.1 0.6 0.2 0.7 1.0 0.6 0.3
0.5 1.5 0.6 0.7 0.5 0.9 0.5 0.8
Construct a frequency tablo using a class Interval width of 0.2 starting at 0,15.
Class Interval Froguency
0.15-0.35

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

c

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
