Haha I wouldn't have gone through with this without an expert's approval, which would have been my doctor in three weeks anyways. Thank you for your time!

Thinking of starting keto, and thought it would be fun to try and live off of coconut milk, low carbohydrate bread, butter, and some kind of meat or fish for dinner. Provided I take a multivitamin, along with calcium and magnesium pills, would this diet be as healthy as any other? Could I be...

I was quite distraught knowing that chegg.com has no textbook solutions for "measure theory" even though it has four for abstract algebra. Could it be that the textbooks are called something else?

Thank you so much again fresh_42!

Homework Statement Prove that Q+, the group of positive rational numbers under multiplication, is isomorphic to a proper subgroup of itself. Homework Equations None The Attempt at a Solution [/B] Not at all sure if this is legit. Let phi: Q+ --> G phi(x) = x2, x is in Q+ We will...

Homework Statement Prove that a finite group is the union of proper subgroups if and only if the group is not cyclic. Homework Equations None The Attempt at a Solution [/B] " => " If the group, call it G, is a union of proper subgroups, then, for every subgroup, there is at least one...

Thanks for reply. But if we write out the notation, then, for group with operation "addition": 250 = 50*2, and 502=2*50, and Z is commutative? That is, in general, an=n*a

Homework Statement Suppose that H is a subgroup of Z under addition and that H contains 2^50 and 3^50. What are the possibilities for H? Homework Equations Relevant concepts are just the definitions for a group and subgroup. https://en.wikipedia.org/wiki/Group_(mathematics)...

That's it! Thank you so much George.

This is the integral: http://www.wolframalpha.com/input/?i=integrate+x%5E2%2Bxy%2F2+from+0+to+x+with+respect+to+y But my calculator (TI-nspire cx CAS) gets this: x*(2x^2+xy)/2 Any idea why this is?

Homework Statement What conclusions can be drawn from this data set? What assumptions are you making? Homework Equations http://i.imgur.com/M9YQGAF.png I hope this is legible. The Attempt at a Solution The solution is what I'm having trouble with. I just don't get how that test statistic has...

I think I've figured it out, much like what you suggested. The sample was intentionally very inaccurate in one place (where it mattered for this exact question, but didn't matter that much as for the correlation to the normal distribution) to emphasize the effect of chance on random selection...

To the best of my ability yes, I just call the sd(x) and mean(x) functions in R

I was not given the values, I calculated them in R with the data set I was given.

Oh, sorry I meant 0.022
