I can tolerate misspellings of people speaking their first language, but math trolling... you have to draw the line some place.
Please, that is why I added the
so as to not be too serious.
Now, I like numbers... and you are well educated in math and science. Perhaps....perhaps I am wrong, but please tell me where I have gone wrong and EvanG is correct.
--- Every year about 720,000 Americans have heart attacks. This is out of about 320 million people. Let's assume there are about 225 million people over age 20. That is 225 * 365 * 24 = 1,971,000 million person hours. So 720,000 heart attacks / 1,971,000 million person hrs = 0.37 heart attacks / million person hrs.
----Then I say ---you have 225 million x 365 x 24, or 1,971,000 million person hours divided by 720,000 heart attacks.
Which gives you 2.73 heart attacks per million person hours, not 0.37
0.37 vs 2.73 Those are wildly different answers
We are looking for the number of heart attacks per million person hours.
So you take the total hours 225 million people times 365 days times 24 hours (1,971,000 million person hours)
EvanG and I both agree on that step and those numbers.
So what do you do with that number? You divide it by the number of heart attacks to get the hours per heart attack.
You take the 1,971,000 million person hours and divide by the 720,000 heart attacks.
That is the number of heart attacks per million person hours
in the general publicThe answer is 2.73... not 0.37
The same problem was in the other equation which was being done for the marathon and half marathon runners
0.55 or 0.56 was the answer, not 1.8
Now do you see the problem more clearly?
BTW, we are not talking about mere spelling or punctuation.
Math is the basis of all the studies and such that we use to decide which course of eating is the best for our health.
The math is the entire story, so we don't want to casually throw facts around if they aren't correct.
