Number one would be 13 because you have to add the x to both sides which will leave you with 2x=26 then you have to divide by 2 and you will get x=13. Number two is 7 7/8 because you have to add the 1/3x to the other 1/3x to get 2/3x= 5 1/4 so then you divide both sides by 2/3 and to divide a fraction you do keep change flip so it would be 21/4 times 3/2 which would be 63/8 which simplifys to 7 7/8.

A box plot is used to study the distribution and level of a set of scores. The box plot consists of whiskers which measure the minimum and maximum numbers. The difference between these numbers is the range which measures variability.

On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.  The difference between the first quartile and the third quartile is the interquartile range.

For the first box plot:

  • Maximum number = 6
  • Minimum number  = 1.5
  • Range = 6 - 1.5 = 4.5
  • Median  = 4
  • First quartile = 3
  • Third quartile = 4.5
  • IQR = 4.5 - 3 = 1.5

For the second box plot:

  • Maximum number = 3.5
  • Minimum number  = 1
  • Range = 3.5 - 1 = 2.5
  • Median  = 2
  • First quartile = 1
  • Third quartile = 2.5
  • IQR = 2.5 - 1 = 1.5

For the third box plot:

  • Maximum number = 5
  • Minimum number  =2.5
  • Range = 5 - 2.5 = 2.5
  • Median  = 4
  • First quartile = 3.5
  • Third quartile = 4.5
  • IQR = 4.5 -  3.5 = 1
