Hi, so I have a question that I know that there must exist some
example for which the following is true, but I don't know what it
would be, as 0 is not positive and 1 is neither prime nor
composite. Please help if you can!
Suppose that a,p,n are positive integers. Consider the
claim:
If p|a^n, then p^n|a^n.
Are there any non-prime, positive integers for which the claim
is true for all positive integers a and n? Justify your...

From Research Methods and Statistics 5th ed. would you explain
to me how to find critical value of z in chapter 8 question 2d?
I found that z=-1.59
Therefore, Z_obt = -1.59
but how do I use Table A.2 to determine Z_cv?
note: I know the answer is -1.65. What I want to know is how do
you get that?

titrated, volume and concentration...

I have a General Question for Statics (Structural Analysis). For
Truss questions (method of joints and zero-force members), how do
you know when you need to find the moment at the pin joint? The
book say's, when each joint has at least three unknown forces. Is
this true? Really confused on how to know when you need to find the
moment or not.

How does the scientific method aid human critical reasoning
processes?
How and why have you made assumptions or inferences on important
matters, regardless of data or evidence to the contrary? Examples
here might include: fad diets, telepathy, precognition,
psychokinesis, vaccinations, UFOs, magnetic therapy, apparitions,
cold fusion, Bigfoot, alternative forms of medicines, genetically
modified plants, etc. Describe how you have thought about this
issue and analyze how you could improve your critical reasoning on
this issue using the scientific method.
