Hey, looks like when she doesn't study, she ALWAYS fails. Don't mean to insult though.
Let's see the difference between the three numbers. 63-58=5. 68-63=5.
We know the difference between each assessment she scores is 5 now!!
Let's put it to use.
Although you don't have multiple choice answers...
after 4 assessments(not including first 3), her score will be above 85!!
Including the first 3 assessments, her score would be above 85 after 7 assessments!!
anyways, I hope this helps!!
To compare these numbers, you must first put them into one format. Since you have mixed numbers, you may have to find and use the LCD.
-2.5, 1/5, 10, -12/4, 18/5, 10 could be simplified somewhat immediately:
-2.5, 1/5, 10, -3, (3 3/5) This set of numbers is simple enough so that you could rearrange them in ascending order mentally:
-3, -2.5, 1/5, (3 3/5), 10
In this case the number of elements in this set is odd, so all you have to do is to select the MIDDLE element: 1/5.
The median is 1/5.
You MUST learn this procedure (arranging the set elements in ascending order and selecting the middle element) so that you can apply it yourself.
