Answer:

All we have to find the fraction of students who preferred green and go from there.

Subtracting blue and red out of the all students,

1- (1/8+1/4)

1- 3/8

5/8 is the remaining students, in order to find 3/5 of the remaining students, we multiply by 3/5

5/8(2/5) = 3/8

3/8 preferred green, which was 15 students. In order to get 100% of the whole  population (1), we multiply by 8/3:

15(8/3) = 40

40 students were surveyed in total.

Identify the type of variation represented by y=3/x
Dmitry [639]

Answer:

Inverse variation

Step-by-step explanation:

Given equation is y=\frac{3}{x}.

Now we need to identify the type of variation represented by  y=\frac{3}{x}.

We know that there are two type of variations direct and inverse.

If y and x are in direct variation then we write equation as  y=kx.

where k is the constant of variation.

If y and x are in inverse variation then we write equation as   y=\frac{k}{x}.

Given equation  y=\frac{3}{x} looks similar to  y=\frac{k}{x}.

So that means finala answer is "Inverse variation".
