Answer: 44%
Step-by-step explanation:
For a circle of radius R, the area is written as:
A = pi*R^2
Where pi = 3.14
If we increase the radius by 20%, the new radius will be:
R´ = R + 0.20*R = 1.20*R
The new area will be:
A´ = pi*(1.20*R)^2 = (1.20)^2*pi*R^2
= 1.44*pi*R^2
And pi*R^2 = A, the original area, then_
A´ = 1.44*A = A + 0.44*A
This means that the percentage in which the area increased is:
0.44*100% = 44%
Answer: 64+8=72...72/9=8

Step-by-step explanation:
The complete table would be the follwing:
A.
To get this probability, we take the total number people who pefer an SUV, and divide it by the total number of people in the sample

B.
To get this probability, we take the total number of females, and divide it by the total number of people in the sample

C.
To get this probability, we take the total number of females who pefer a car, and divide it by the total number of people in the sample

D.

E.

F.
