To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile
Inter quartile range is the middle 50% of the given range of scores.
The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%
From the diagram , we can see that
Upper quartile = 89
lower quartile = 65
So range is 65% to 89%

Answer:
Factoring is taking the greatest factor of an equation/expression and putting it behind parenthesis.
For example:
2+4: Factor it
2 is the greatest factor of the two
SO
2(1+2)
Ill give you a try it and you can factor it. I might check it later on.
42+ 36
If you are looking for something harder:
4x^4+ 6x^6
