This question is flawed. I believe it was meant to ask: "If you ask a random person <span>who identifies as American</span> this question, what is the probability?" etc. Assuming this is the case, it would be 93% probability.
Otherwise, America is equivalent to 4.34% of the total world population as of Thursday, April 6, 2017 (http://www.worldometers.info/world-population/us-population/). So, 7% of 4.34% is 0.3%.
I'd stick to 93%
The answers on the right are in reverse order to the questions on the left.
I find it easier to see if I have a picture.

Step-by-step explanation:
Think process:
The equation is given as y = ![e^{-3x}](https://tex.z-dn.net/?f=e%5E%7B-3x%7D)
Let, y = f (x)
Therefore, ![f (x) = e^{-3x}](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%20e%5E%7B-3x%7D)
We know that the limits are y-axis and x= 3
Y-axis: x= 0
then limits are given as x= 0 and x = 3
Integrating gives:
=
+ C
calculating from x= 0 to x = 3, we know volume is given by ![\pi \int\limits^a_b {f(x)} \, dx](https://tex.z-dn.net/?f=%5Cpi%20%5Cint%5Climits%5Ea_b%20%7Bf%28x%29%7D%20%5C%2C%20dx)

Answer:
0.50 or 0.500
Step-by-step explanation:
You can add a number of 0's after the 5 and the number will still stay the same.
Total number of hours she schduled to play the game = 3
hours.
Let us convert mixed fraction into improper fraction
![3\frac{3}{4} = \frac{3*3+4}{4} = \frac{13}{4} \ hours.](https://tex.z-dn.net/?f=3%5Cfrac%7B3%7D%7B4%7D%20%3D%20%5Cfrac%7B3%2A3%2B4%7D%7B4%7D%20%3D%20%5Cfrac%7B13%7D%7B4%7D%20%5C%20hours.)
Duration of each round =
.
In order to find the number of rounds Nicole can play, we need to divide total number of hours by duration of each round.
÷ ![\frac{7}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B12%7D)
Converting division sign into multiplication flips the second fraction.
![=\frac{13}{4} \times \frac{12}{7}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B13%7D%7B4%7D%20%5Ctimes%20%5Cfrac%7B12%7D%7B7%7D)
Crossing out 12 by 4, we get 3 on the top of second fraction.
![=\frac{13}{1} \times \frac{3}{7}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B13%7D%7B1%7D%20%5Ctimes%20%5Cfrac%7B3%7D%7B7%7D)
![=\frac{39}{7} = 5.57...( Approximately).](https://tex.z-dn.net/?f=%3D%5Cfrac%7B39%7D%7B7%7D%20%20%3D%205.57...%28%20Approximately%29.)
Because problem is about number of rounds.
So, total number of round would be 5.
