Ascatterplot has a positive, linear correlation. which statement is true about the relationship between the x- and y-values? as the x-values increase, the y-values tend to increase. as the x-values increase, the y-values tend to decrease. as the x-values decrease, the y-values tend to increase. as the x-values decrease, the y-values tend to vary randomly.

As the X values increase the Y values also tend to increase'

Step-by-step explanation:

The statement which is true about the relationship between the x- and y-values is:

It is given that:

A scatter plot has a positive, linear correlation.

Positive correlation means that with the increase/decrease in one variable the other variable also increases/decreases

i.e. there is a direct proportion between the two variables.

Also, linear correlation means that the point lie along a straight line.

            Hence, the correct answer is:

   As the x-values increase, the y-values tend to increase.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
