Answer:
A) 8%
Step-by-step explanation:
A confidence interval of proportions has an upper end and a lower end.
The margin of error is the difference between these points divided by two. Also, it is the upper end subtracted by the estimated proportion, or the estimated proportion subtracted by the lower end.
In this problem, we have that:
Upper end: 0.68
Lower end: 0.52
Margin of error
The margin of error is 8%.
So the correct answer is:
A) 8%
The surface area of a sphere is A = 4π R²
The volume of a sphere is V = (4/3) ( π) (R³)
The ratio of (surface area) to (volume) is
4 π R² / (4/3) (π) (R³)
Divide top and bottom by 4π : R² / (1/3) (R³)
Multiply top and bottom by 3: 3 R² / R³
Divide top and bottom by R² : 3 / R .
For the Earth,
A / V = (3) / (3,960 miles) =<em> 0.00076 per mile </em>(rounded)
