Answer:
N(L) = 20
The expected number of left handed people is 20.
Step-by-step explanation:
Given;
Percentage of left handed people P(L) = 10%
Total number of selected people N(T) = 200
The Expected number of left handed people N(L) is;
N(L) = Total number of selected people × Percentage of left handed people/100%
N(L) = N(T) × P(L)/100%
Substituting the given values;
N(L) = 200 × 10%/100%
N(L) = 200 × 0.1
N(L) = 20
The expected number of left handed people is 20.

Step-by-step explanation:
Solution.
Given, Right angled triangle
where reference angle given 48
hypotenuse(h)=80
perpendicular(p)=x
Now ,
I) sin48=p/h
or,sin48×h=p
or0.978×80=x
.°. 59.5=x
Answer: 40 by 60
Step-by-step explanation:
You are given a scale of 1 inches=20 ft
