Area of circle = pi r^2 = 3.14 x 4^2 = 50.24 square miles

Quarter circle's area = 50.24 /4 = 12.56 square miles

Answer:

12.56 square miles

So we first have to find the area of the whole circle using A = πr^2 then dividing it by 4
A= π*4^2
A= 16π or 50.27
So now we take the whole area and divide it by 4 so the answer is 12.57

A study of consumer smoking habits includes 193 people in the 18-22 age bracket (60 of whom smoke), 127 people in the 23-30 age

Thepotemich [5.8K]

Total number of people in the sample = 193 + 127 + 96 = 416

Probability of picking 23-30 year old = 92 /416 = 0.2212 ( not including the people who smoke)

Number of people who smoke = 60+35+23 = 118 people

Prob(someone who smokes) = 118/416 = 0.2837

So required probability = 0.2837 + 0.2212 = 0.505 (answer)
