In a group of mherchants, 80% of them purchase goods from asia, and 25% of them purchase goods from europe. which of following statement is individually sufficient to calculate what percent of the merchants in the group purchase goods from europe but not form asia? 7. 25% of the merchants who purchase goods from asia also purchase from europe. 15% of all merchants purchase goods from neither asia nor europe 0% of all merchants purchase good from both asia and europe

7. 25% of the merchants who purchase goods from Asia also purchase from Europe.

Step-by-step explanation:

I am going to say that:

A is the percentage of merchants who purchase goods from Asia.

B is the percentage of merchants who purchase goods from Europe.

We have that:

In which a is the probability that a merchant purchases goods from Asia but not from Europe and is the probability that a merchant purchases goods from both Asia and Europe.

By the same logic, we have that:

Which of following statement is individually sufficient to calculate what percent of the merchants in the group purchase goods from Europe but not form Asia?

We already have B.

Knowing , that is, the percentage of those who purchase from both Asia and Europe, we can find b.

So the correct answer is:

7. 25% of the merchants who purchase goods from Asia also purchase from Europe.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
