Hello sir!
It seems as if this is a statement? Seemingly this is David Hilbert's mathematical problem that has yet to be solved.
"The Riemann hypothesis implies results about the distribution of prime numbers. Along with suitable generalizations, some mathematicians consider it the most important unresolved problem in pure mathematics (Bombieri 2000). The Riemann hypothesis, along with Goldbach's conjecture, is part of Hilbert's eighth problem in David Hilbert's list of 23 unsolved problems; it is also one of the Clay Mathematics Institute's Millennium Prize Problems."
Hope this helps! :)
The answer is B. +$200. Because when Ralph purchased the vase for $400 and is selling them at a higher price for $600. The difference is $200. He has gained $200 as a profit for every vase that is sold.
The answer is D or the fourth choice, 12
Please mark me as brainliest I would really love it.
