Answer:
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.

It looks like your first selection (a) is appropriate.

Answer:
The 22nd Term is -77.
Step-by-step explanation:
The pattern is -5. If you subtract 5 from each starting number you'll get the following number.
Ex: 28 - 23 = 5
23 - 18 = 5
18 - 13 = 5
Subtract 5, 22 times and you will get -77.
I hope this was the most brainliest answer, thank you for letting me help you !
