The mean score on a driving exam for a group of driver's education students is 84 points, with a standard deviation of 4 points. apply chebychev's theorem to the data using k=2. interpret the results at least % of the exam scores fall blank and blank

The corrects answers are B and D for this one. 

Since you divide the same side for both the the rectangles on both parts and if the division statements are equaled, then they are similar. 

For example; 

Answer B. 
50 / 10 = 5 
and 
30 / 6 = 5 

Answer D. 
7.5 / 2.5 = 3
and 
4.5 / 1.5 = 3 

Since they both equal the same for both of the rectangles for the answers individually, they are similar polygon rectangles. 

Hope this helps!
