The table above shows the high temperature last Thursday for five cities, A through E. If the median of the Thursday high
temperature for these cities was 81°F, which of the following could NOT have been the high temperature last Thursday of city
A?

Respuesta :

Answer:85

Step-by-step explanation:

[tex]F[/tex]High temperature last Thursday of city is [tex]85[/tex]°

  • (A) is correct.
  • If the median of the Thursday high temperatures for the five cities was

        [tex]81[/tex]°[tex]F[/tex],then the five high temperatures are listed in order from greatest          

         to least (or least to greatest),

                A.[tex]85[/tex]°[tex]F[/tex]

                B.[tex]75[/tex]°[tex]F[/tex]

               C.[tex]65[/tex]°[tex]F[/tex]

               D.[tex]55[/tex]°[tex]F[/tex]

  • Since the three greatest known high temperatures are [tex]91[/tex]°[tex]F[/tex]., [tex]87[/tex]°

        [tex]81[/tex]°[tex]F[/tex].

  • [tex]81[/tex]°[tex]F[/tex] must be the third temperature in the list.
  • The unknown high temperature for City A must be less than or equal to

         [tex]81[/tex]°[tex]F[/tex].

  • Thus, [tex]85[/tex]°[tex]F[/tex] is NOT less than or equal to [tex]81[/tex]°
  • Therefore only [tex]85[/tex]°[tex]F[/tex] could NOT have been the high temperature last Thursday for City A.
