Which graph best represents the following situation?
as x increases, y increases; r = 0.42

graph a
graph b
graph c
graph d

Graph B

Step-by-step explanation:

we know that

The graph that represent the situation

As x increases, y increases

Is the graph B or the graph C

but

Graph B represent a moderate coefficient of correlation r (-0.5 to -0.3 or 0.3 to 0.5)

Graph C represent a strong coefficient of correlation r (-1.0 to -0.5 or 1.0 to 0.5)

In this problem we have r=0.42

so

The coefficient of correlation is Moderate

therefore

The answer is the Graph B

it 2

step-by-step explanation:

8^1/3=2

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
