Need help assap A histogram is being made for the following set of data. If the length of each interval is going to be 7, how many bars will there be on the histogram?

78, 92, 98, 87, 86, 72, 92, 81, 86, 92

A. 7

B. 4

C. 5

D. 6

I would think it is A but that could be wrong

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

it has the same slope and a different y-intercept

hope this : )
