Find the class limits for a frequency table with seven classes

Class width for a frequency table with seven classes is 12.

Step-by-step explanation:

103-20)/7 = 83/7 = 11 + 6/7, so yes 12

20-32 --> bucket #1

33-45 --> bucket #2

46-58--> bucket #3

69-81 --> bucket #4

82-94--> bucket #5

95-107 --> bucket #6

108-120 --> bucket #7

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
