Find the square root of the following by long division method
a) 6724

82.

Step-by-step explanation:

             8  2                   < square root

 8   |    67, 24 . 00,00    (mark the number off in pairs from dec. point)

       |    64                             (8*8 = 64)

162 |      324                         ( Subtract 67 - 64 = 3 then bring down the 24)

               324                          (8 *2 = 16  and  324 = 2 * 162)

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.
