The frequency table below will be used to make a histogram. what ia an appropriate scale and interval for this histogram?

a. the scale shod be 0 - 10, and interval should be 10

b. the scale should be 0 - 15, and interval should be 5

c. the scale should be 1 - 10, and interval should be 5

d. the scale should be 1 - 15,and interval should be 10

D

Step-by-step explanation:

Answers A and C are cancelled immediately because 71-80 has 11 number of students, thus the scale cannot be 0-10 since that would mean the data for test scores 71-80 to be cut off

The answer is not B because the having 5 as the interval is too low and would make the histogram stretch out when 10 can make it shorter and look nicer.

side 1: t - 1

side 2: t + 1

side 3: 4

side 1 + side 2 > side 3   &  side 2 + side 3 > side 1   &  side 3 + side 1 > side 2

(t - 1)   + (t + 1)   >   4              (t + 1)   +   (4)    >   (t - 1)            (4)     + (t - 1)  >  (t + 1)

       2t > 4                                  t + 5          >   t - 1                      t + 3       >   t + 1

         t > 2                                       5 > -1   (TRUE)                            3 > 1 (TRUE)

t > 2
