Answer:
x = 20
Step-by-step explanation:
In similar polygons, all corresponding sides are proportional. The scale factor between AB and DE is the same as between AC and DF.
You can confirm that by plugging it back into the original equation:
Answer:

Step-by-step explanation:
Answer:
Connect the two centers to produce the trend line
Step-by-step explanation:
When the dots have been plotted, there are three steps to find the trend line on a scatter plot:
1. Draw a vertical line that separates the full set of points into two sets, each with the same number of dots.
2.Mark with a special sign (e.g + or ×) the middle value in each of the two sets obtained in the previous step.
3.Join the two marks mentioned in the step (2) with a straight line, and extend it to the edges of the graph. This line is the trend line, and this is the last step.
Thus, the last step when using the divide-center method to find the line on scatter plot is Connect the two centers to produce the trend line.
