Hi Макс,
you can find the derivation for the formula in the course notes. They are in the lecture “Segmentation, Targeting, Positioning”, under the quiz. Here is a link:

Hi! Thanks for your answer! But I'm sorry to say that I didn't find the explanation there. There are just formulas with no derivation. It'll be very interesting to understand more deeply where do they come from.
Hi Макс,
the formula derivations are in a separate pdf, which you can download here:

Sorry for the misunderstanding!
