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%

Answer:
Step-by-step explanation:
1) Plug numbers into slope formula to find 
.
2) Simplify to find .
3) Check work.
This statement is true.
4) Write equation.
Answer:
f(x) = 3 cos (2Pi / period value ; x )+ 2
or see answer using 2 as the period see answer in bold below.
Step-by-step explanation:
cosine function amplitude of 3 is A = 3
The period is used to find B
You need to show period value as the denominator and work out from there with 2PI as a function numerator to show as 2pi / period can be a data angle
C is the adding value.
Acos (Bx) + C
A = 3
Bx = 2 pi / period
C = + 2
However f 2 is also the period found
then we just plug in 2 to above formula
f(x) = 3 cos (2Pi / 2 ; x )+ 2
f(x) = 3cos (x pi) + 2
Lets day the original price of the dvd player was $100,
36% marked down means you pay $64x
64x = $41.60
100x = 100/54 x 41.60 = 4160/64 = #65.00 = original cost
similarly, stereo tuners = 100/78 x 69.42 = 6942/78 = $89 original cost
DVD = 65- 41.60 = $ 23. 40 less
Stereo = 89- 69.42 = $ 19.58 less
Diffrence is $ 3.82
so your answer is the dvd player price was reduced by $3.82 more than the stereo tuner.
