<h3>What is the correlation coefficient?</h3>

Correlation is a measure that is used in statistics to determine the linear relationship that exists between two variables. Correlation can be positive, negative or zero.

Positive correlation is when two variables move in the same direction. Negative correlation is when two variables move in opposite directions. Zero correlation is when there is no relationship between the variables.

Correlation can be determined using a financial calculator. When the financial calculator is used, the correlation coefficient is -0.52

Which graph shows f(c)=0.5|x+3|-2
iVinArrow [24]

The graph that shows f(c)=0.5|x+3|-2 has been added in the attachment.

<h3>How to solve for the graph</h3>

We are given the equation to be f(x) = 0.5|x + 3| – 2

This equation above is an absolute value equation that was entered into a graphing calculator

The absolute value equation is represented by the values

f(x) = a|x - h| + k

in the equation above, h and k are the vertex of the graph

when we compare the absolute value equation with the equation we have in the question, we would have h = +3 and k = -2

Hence we would say that the vertex is 3 , -2.

When the graph was plotted, the vertex is the point that shows that meeting at a point in the point 3, - 2 are shown as the vertex also

9[n+2(n-2)]=45<br><br><br>how do u answer this question it has to many numbers.​
liq [111]

Answer:

n = 3

Step-by-step explanation:

9{n+2(n-2)} = 45

Start with the numbers on the inner most pair of parentheses

Multiply (n-2) by 2

9[n+2n-4] = 45

Add what is inside the parentheses

9[3n-4] = 45

Multiply

27n-36 = 45

Add 36 to both sides

27n = 81

Divide both sides by 27

n = 3

Hope this helps!
