Why studying economics is very hard

Step-by-step explanation:

Economics is a branch of social science and it deals with more of observations, theories, laws, deductions and construction of abstracts model.

So, to do all of these, economists need to be good at mathematics to approach some of these abstracts model.

Like all other scientist, economists also do hypothesis to allow them study the economy growth and help them construct a model that solve this goals these requires a lot of mathematical models and abstract reasoning. They usually employ mathematical and graphical models and analysis to solve the economic issue e.g. demand and supply curves analysis

Economic models usually employ graphical and mathematical analysis to help explain and illustrate such economic processes.

All of these makes economic very hard to study. So to study economics, you need to be good at mathematics

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
