The location of the image of points <em>J </em>and <em>K </em>following a reflection across the x-axis are;
- J'(-3, -4), and K'(3, -4)
<h3>Which method can be used to find the image of a point following a reflection?</h3>
Coordinates of point are;
J(-3, 4), K(3, 4)
The given transformation is; A reflection across the x-axis
The representation of a reflection across the x-axis is presented as follows;
The image of <em>J </em>and <em>K </em>following a transformation across the x-axis are therefore;

Answer:
The correlation between hour of the day and the speed over the limit at which the motorist is ticketed is weak positive correlation.
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.
The types of correlation coefficient are:
- +1 (-1) : Perfect positive (negative) correlation
- 0 to 0.30(-0.30) : Weak positive (negative) correlation
- 0.30(-0.30) to 0.70(-0.70) : Moderate positive (negative) correlation
- 0.70(-0.70) to 1 (-1) : Strong positive (negative) correlation
The correlation coefficient value between the hour of the day and the speed over the limit at which the motorist is ticketed is:
<em>r</em> = 0.12.
The value of <em>r</em> lies between:
0 < 0.12 < 0.30
Thus, the correlation between hour of the day and the speed over the limit at which the motorist is ticketed is weak positive correlation.
