Answer:
-23x + 9
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
We want to solve the equation:
For the interval [0, 2π).
First, we can move all the terms to one side. Start off by subtracting sin(x) from both sides:
We can factor:
By the Zero Product Property:
Solve for each case:
Use the unit circle to solve:
Hence, our answer is A.
*Please note that we should not simply divide both sides by sin(x) to acquire 2sin(x) = 1. The problem with the operation is that we are dividing by sin(x), yet we do not know what the value of x is. Thus, one or more values of x may result in sin(x) = 0, and we cannot divide by 0. Hence, we are required to subtract and then factor, unless the question specifically states that sin(x) ≠ 0.
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%
