d³s hybridization in Coordination Compounds

If asked for the hybridization of any of these compounds below, should I mention sp³ or d³s? D-block chapter mentions nothing about this for KMnO4 even.

Hydrocarbons, Saytzeff/Hofmann product

The answer is Hofmann product here even though the base is small. I assume its because N(CH3)3 is a poor LG? * Is N(CH3)3+ a poor leaving group? Why/why not? * If it is, what decides whether 'small base' dominates or 'poor LG' dominates?...

solutions

a 95 mass percent solution of ethanol is further diluted with water if the mole fraction of ethanol in dillute solution is 0.25 what is the mole fraction of water in the dilute solution is it still an ideal solution dude what is going on in this question...

Integration and limits

My approach was writing it as $\frac{\int_{x}^{2x}{\frac{sin^{m}(x)}{x^{n}}}}{x} \cdot x$ and then approximating the fraction thing to derivative of integral of $\frac{sin^{m}(x)}{x^{n}}$ which is that function itself, but unable to go on from there.
