Answer:
sqrt(2)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 45 = x/2
2 sin 45 =x
2 (sqrt(2)/2) =x
sqrt(2) =x
under 21 years of age= 40 25 20 tot= 85
between 21 and 40= 35 20 30 tot = 85
over 40= 20 30 35 tot = 85
If one of the 255 subjects is randomly selected
P (over 40) = 85/255 = 1/3
Hope this helps!
