While we're very happy to have you in the Gulch and appreciate your wanting to fully engage, some things in the Gulch (e.g. voting, links in comments) are a privilege, not a right. To get you up to speed as quickly as possible, we've provided two options for earning these privileges.

Just teasing DB. You probably know this too.
I only used the more complicated form a little, long time ago, when doing some 1-D modeling of multiphase fluid systems, and wanted to account for fluids (refrigerants) that I didn't have tables for.

I take issue with the questions about the graph showing a correlation between sugar and cavities. Their answer is it shows "the more sugar people eat, the more likely they are to get cavities." I understand what they mean, but this sounds like they're saying post hoc ergo propter hoc. We don't know from the graph if there is a third factor that causes people to eat sugar and get cavities. Maybe the people who eat more sugar also eat less of some vitamin, and the lack of that vitamin leads to cavities.
I know the scientific evidence is sugar causes cavities, but based only on that graph we cannot tell if eating more sugar makes someone more likely to get cavities.
I got 12/12.
This statement, in my reading, implies if members of the same cohort changed no variables other than sugar consumption, it would change their rate of cavities. This means causal correlation.
Multiple guess is popular because it is easy to grade, and easy to defend in disputes about grading.

Or here is a quick article on the subject.

Actually cavities have little to do with sugar per say, there are other factors to consider.
All this stuff, I founded out waaaaay to late in life.
Oh well...
Seriously, six times a day and for sure after eating is not too excessive. Followed by a good mouth wash. As the others said it's 'germs and bacteria.'
And a new toothbrush
Try this...
1) Four or five heaping tablespoons of cocoanut oil
2) one teaspoon baking soda
3) Stevia to taste
4) a few drops of peppermint extract to taste
5) a few drops of lemon extract to taste
Mix the whole mess together and brush twice daily. I've been using this for a year or so now, no cavities and my teeth have never felt cleaner. The bonus is no fluoride!
But what is the bit about guessing?
And the Doppler Effect describes the change in Apparent Frequency of sound, light, radio, etc., waves, depending on whether YOU or The Source are moving towards each other or apart.... the old train-whistle example.
Cheers!
That must have been the REAL test!
12 of 12 correct! :) I found it to be a relatively easy and fun quiz. I love science. One confession: I could not recall the name of the developer of the polio vaccine, but thorough process of elimination I was able to deduce the correct choice.
Respectfully,
O.A.
Given the following two statements as premisses:
Logic is difficult, or not many students like logic.
If mathematics is easy, then logic is not difficult.
is it valid to conclude:
1)that mathematics is not easy, if many students like logic?
2)that not many students like logic, if mathematics is not easy?
3)that logic is not difficult, or mathematics is easy?
4)that mathematics is not easy, or logic is difficult?
5)that logic is not difficult, or mathematics is not easy?
6)that logic is difficult, or mathematics is easy?
7)that if not many students like logic, then (a)mathematics is not easy, or (b) logic is not difficult?
YES or NO

12 for 12 see link if you like but even though they were easy I still surprised myself.

sented myself as a scientist.
when they said "... how the positions of the stars and the planets
can affect human life," and (2) they inserted "race" as a
category when "race" was not requested in the questions.
this tells me that Pew Research is leftist. -- j
