The lamia from FFXI were magical experiments and did not in fact have the ability to reproduce.

Neither

I think it will be giving birth, why? idk I can say anything, maybe because, if that happen, the "living thing" will be big, and is often seen that great species don't lay eggs

Question is not clear. You're given
Gross = Net - Tax
Tax = Gross * X - B

And you want to solve for what as a function of what?

In a real situation, we are only given the Net amount.

Given that I know what X and B are for that particular figure, I want to be able to figure out the tax on Net.

We're too heavily dependent on it that a switch to alternative sources for fuel will take decades to happen

Let me try CLT again:
[eqn] \frac{X_1 + ... + X_n}{\sqrt{n}} \to N(0,\sigma).[/eqn]

>>7654155
Just for completeness, in case a statistician shows up that is unfamiliar with the number theory: the Mobius function [math]\mu(n)[/math] takes value either [math]-1, 0, 1[/math] depending on the prime factors of n so that it is 0 when n is divisible by a square, -1 when divisible by an odd number of distinct primes, and 1 otherwise. So if there's no bias in number to have even or odd prime number of divisors, the mean of [math]\mu(n) = \lim_{x \to \infty} \frac{1}{x} \sum_{n \le x} \mu(n) [/math] should be 0, and the error term is given explicitly based on where [math]\zeta(s) \neq 0[/math], hence the relation to the Riemann hypothesis. But I'm hoping for a statistical heuristic that could explain why, in some sense.

>>7654167
One more post, sorry.

It is a theorem (equivalent to the famous Prime Number Theorem!) that
[eqn] M(\mu) = \lim_{x \to \infty} \frac{1}{x} \sum_{n \le x} \mu(n) = 0[/eqn]
and the Riemann hypothesis is that we have the estimate
[eqn] \frac{1}{x} \sum_{n \le x} \mu(n) = O(x^{1/2+\varepsilon}).[/eqn]
That should make more sense.

It can have different melting points depending on how the crystal structure of the alloy is.

Silly you, Galinstan is an alloy of Gallium and some other stuff.

it doesn't cure cancer you dumbfuck it just alleviates some of the pain caused by cancer symptoms.

Grades don't matter. Sorry to burst your bubble. What matters is that you learn problem solving skills. Trying to figure it out yourself, even without information is a noble pursuit. When you get into the real world and are asked to create something completely new and novel, you can't just ask someone how to do it. You have to think for yourself.

Also, that's a shitty class if it doesn't have readings or notes. Maybe check the class facebook page. In all my classes we had a shared google doc with the "learned material," so if any of us missed something, all of us missed it, and if any of us had something, all of us had it.

Otherwise you will have to rely purely on the power of your own logic, as Aristotle did.

You clearly aren't good at learning things if you can't even figure out a fucking And gate.

mathematicians are too dumb

There are ten constants of motion:

Three position co-ordinates for the centre of mass of the system
Three velocity co-ordinates for the centre of mass of the system
Three vector components for the angular momentum of the system
Total energy of the system

There are 18 unknowns in the system
Three position co-ordinates for each body (nine in total)
Three velocity co-ordinates for each body (nine in total)

Try to solve a linear system of 10 equations and 18 unknowns. Can't be done.

Oh so that's why the double slit experiment gives unpredictable results!

Browse 4chan instead of getting shit done. My IQ is 134 with a standard deviation of 15.

>>7653822
Think about how superior they are.

Depends on the person. Remember that IQ, while it makes an okay estimate of mental skills, gauges pattern recognition junk better than anything else. So the question you should probably ask is what people exceptionally talented in their field do all day. There the answer is obvious. They got so damn good by doing work in their field all the time.

>Is thorium a meme?
Yes.

>Are thorium reactors they as miraculous as this video and everyone seems to be telling me?
Of course not.

>If so...?
They're not.

Can we please just leave it at that?

>>7653718
They are good.
If you can get one running that is.
The biggest offset is the creation of a liquid salt holding facility and mining.

Picture this: You have to start mining for a material that has never really been sourced before AND you must start the first ever factory with equipment JUST for the processing of thorium.

>>7653734
But if this was subsidized as most nuclear energy projects are, that would just be an opening investment wouldn't it? If they truly work, it should pay off.

>Can we please just leave it at that?
If you want, but I'd like to know what the big obstacle is, if only for ammunition against these people.

TI-89 will do you for anything in college and grad school.

HP and Casio are for poor plebs.

God you live in a pleb country

Get a ti-89. Combines the simplicity of the 84 with the bonus of the CAS

>>7653709
>>7653711

also suggest ti-89 if you are in physics.

The matter which makes up your brain is physically disconnected from all the other brains. That is what makes your consciousness be associated with your flesh in particular. As a kid I was a bit weirded out by this, but once you weed out the dualism it's not complicated.

>>7653698
But why am I me?

>>7653689
What if consciousness is unrelated to your brain?
