Answer:
Rotation
Step-by-step explanation:
The figure appears to have been rotated 180 degrees about the origin.
The graph is a function because when you use the vertical line test it does not hit more than one point at any given place on the line.
Hope this helped :)
Answer:
The strongest relation between the two factors is B.) -0.8
Step-by-step explanation:
The correlation coefficient typically varies from -1 to 1.
The value of -1 for the correlation coefficient denotes that the two variables are have a very strong negative correlation.
The value of +1 for the correlation coefficient denotes that the two variables are have a very strong negative correlation.
Therefore among the four options given of -0.15, -0.8, 0.38, 0.03 the strongest relation between two factors is given by -0.8 but as the '-' sign indicates the two factors are negatively correlated.
Negative correlation means that if one variable is high the other would be low.
Positive correlation means that if one variable is high then the other variable is also high and if one variable is low then the other is also low.
Answer:

<em />
Step-by-step explanation:
Given
In 1990; Income= $39000
In 2010; Income= $70768
Solving (a): An equation in form of f(x) = ax + b
First, we need to determine the slope, a
Taking y as income and x as year index.
When x = 0; y = 39000
When x = 20; y = 70768
Substitute these values in the above formula
Next, is to determine the formula using:
<em>Considering :When x = 0; y = 39000, we have</em>
<em />
<em />
<em />
<em />
<em>Make y the subject of formula</em>
<em />
<em />
<em />
<em>Express y as a function of x</em>
<em /><em />
Solving (b): Income in 2005
<em>In 2005, x = 15</em>
So:
