the question says that the samples included 100 people each, so it's just 100 multiplied by the amount of samples:
7×100=700
Answer:
A
Step-by-step explanation:
As each person counts as 0.02 since theres 50 people in each, A has the correct conclusion and probability count of 0.12 (adult) and 0.40 (child)
Triangle area formula: base*height/2
so, 14*10/2 = 7*10 = 70 sq. in.
It would be 20
21.3
-1.8
------
19.5 rounded would be 20
