I suppose that is possible to have success with minimal efforts in programming (of course, don't be completely stranger).
Not necessarily but you will be expected to understand computing - as a tool for aiding complex calculations, not an end in itself. You are right about the maths, but economics? Engineering is the practical application of science, principally physics but also chemistry.
Yes, math is more closely applicable to physics, chemistry, and engineering, than biology and programming are.
Because the majority of economics, physics and engineering and general chemistry requires you to be able to calculate, not just learning concepts.
I'm good at Math and I passed Chemistry.
Not so sure about economics but you will need physics.
no
Such a correlation is absurd.
Not necessarily.
Not as much as weakness in science - no good being an expert at programming if you don't understand what it is you are trying to make the computer calculate. I'd be mroe worried about the relevance or not of economics!
yes
Of course, there isn't a reason not to, because mathematics is the language of economics, science and engineering(with the exception of computer programming).
Yes.
