Answer: North Korea and Cuba are the only places you can't buy Coca-Cola
Step-by-step explanation: I think that's a really interesting fact lol.
The mean of a dataset is simply the sum of the elements, divided by how many elements you have.
In your case, you have a dataset of 10 elements, so we will divide by 10.
The sum of the elements is
Which implies that the average is
Which should be approximated to 8.
So you would use the law of sines so set up the equation sin18/16 = sin72/x (sin 72 being the top angle) and then you cross multiply and solve from there:)
Hope this helps!
Answer:
√2x+8=x-8
2x+8=x^2-16x+64
-x^2+18x-56=0
x^2-18x+56=0
x(x-4)-14(x-4)=0
(X-4)(x-14)=0
x=4(extraneous) ,x=14
—> x=14
