Answer:

a = 1

Step-by-step explanation:

Given

4x - 3(x + a) = 2

x  = 5

Required

Determine the value of a

4x - 3(x + a) = 2

Substitute 5 for x

4(5) - 3(5 + a) = 2

Open all brackets

20 - 15 - 3a = 2

5 - 3a = 2

Collect Like Terms

-3a = 2 - 5

-3a = -3

Solve for a

a = -3/-3

a = 1

In a group of mherchants, 80% of them purchase goods from Asia, and 25% of them purchase goods from Europe. Which of following s

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:

A = a + (A \cap B)

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

By the same logic, we have that:

B = b + (A \cap B)

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 A \cap B, 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.

Point A is at-4 and point B is at 6. Which describes one way to find the point that divides AB into a 3:2 ratio?
galben [10]

The point that divides AB into a 3:2 ratio is calculated by (d) for a ratio of 3:2, divide AB into 5 equal parts. Each equal part is 2 units, so the point that divides AB into a 3:2 ratio is 2

<h3>How to determine the ratio?</h3>

The given parameters are:

A = -4

B = 6

Start by calculating the length AB using:

AB = |B - A|

This gives

AB = |6 -(-4)|

Evaluate

AB = 10

Next, the length is divided into 5 parts.

So, the length of each part is:

Length = 10/5

Length = 2

The point on the location 3 : 2 is then calculated as:

Point = A + 3 * Length

This gives

Point = -4 + 3 * 2

Evaluate

Point = 2

The above computation is represented by option (d)
