Students were surveyed about their favorite colors 1/4 preferred red, 1/8 preferred blue, 3/5 preferred green. If 15 students pr
const2013 [10]

Answer:

Let us assume the total number of students surveyed = x

Then

Number of students preferring red = x/4

Number of students preferring blue = x/8

Then

Number of students remaining = x - [(x/4) + (x/8)]

                                                  =x - [(2x + x)/8)

                                                  = x - (3x/8)

                                                  = (8x - 3x)/8

                                                  = 5x/8

Number of students preferring the color green = (3/5) * (5x/8)

                                                                          = 3x/8

We also know that the total number of students preferring the color green is 15

So

3x/8 = 15

3x = 15 * 8

x = (15 * 8)/3

  = 5 * 8

  = 40

So in total 40 students were surveyed. I hope the procedure is clear to you.

F(x) = x^2, g(x) = 2/3 x^2 comparison
daser333 [38]

Answer:

g(x) is a vertical compression of f(x)

Step-by-step explanation:

Equation of graph 1 :f(x)=x^2

Equation of graph 2 :g(x)=\frac{2}{3}x^2

f(x)→a f(x)

Its is case of vertical stretch or compression

Vertical stretch if |a|>1

Vertical compression if 0<|a|<1

f(x)→a f(x)

So, x^2 →\frac{2}{3}x^2

So, a= \frac{2}{3}=0.67

So,0<|a|<1

So,It is a case of vertical compression

So, g(x) is a vertical compression of f(x)
