Which of the statement about the correlation coefficient is true?
Oksana_A [137]

Answer:

The correct statement is (B).

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

If there is any alteration in the value of one variable, the value of the other variable is altered in a fixed proportion. The correlation amid them is known as perfect correlation.

In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.  

Positive correlation is an association amid two variables in which both variables change in the same direction.  

A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.

A correlation coefficient of 0 implies that there is no relationship between the two variables.

Thus, the correct statement is (B).

Show that 5x^2 + 2x - 3 &lt; 0 can be written in the form | x + 1/5 | &lt; 4/5
Sliva [168]

Step-by-step explanation:

First let solve the inequality

5 {x}^{2}  + 2x - 3 < 0

Factor by grouping

5 {x}^{2}  + 5x - 3x - 3 < 0

5x(x + 1) - 3(x + 1)

So the factor are

(5x - 3)(x + 1)

So the factor are

x =  \frac{3}{5}

and

x =  - 1

Solutions to a quadratic can be represented by a absolute value equation because remeber quadratics

creates 2 roots and/or double roots.

The inequality

|x - b|   <  c

works as

b is the midpoint between 2 roots. And c is the

|x + b|  = c

We know that the midpoint between both roots is-1/5.

so

|x - ( -  \frac{1}{5} )|  < c

|x +  \frac{1}{5} |  < c

Let use roots 3/5

| \frac{3}{5}  +  \frac{1}{5} |  =  \frac{4}{5}

-1 works as well.

| - 1 +  \frac{1}{5} |  =   |   -   \frac{4}{5} |  =  \frac{4}{5}

So the absolute value equation is

|x +  \frac{1}{5} |  <  \frac{4}{5}
