Which statement about a histogram is true? a) histograms can plot both positive and negative values on both axes. b) histograms can be used to exhibit the shape of distributions. c) histograms are plots of individual data values. d) histograms show the division of quartile regions for a distribution.

Option B is true.

Step-by-step explanation:

B. Histograms can be used to exhibit the shape of distributions.

A histogram is used to graphically display data using bars of different heights. The shape of a distribution is based on the data's uniformity. The shape is described by the number of peaks a histogram can have.  The histograms count the frequency of each possible answer. This makes it easy for us to see the common or uncommon results.

step-by-step explanation:

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
