Which of the following is the additive inverse of 1/2 options are -2, -1/2, and 2

The additive inverse of a number, say a, is the number that, when added to a, gives zero.

The additive inverse of a real number is usually the negation (the number changes sign) of the original number.
i.e. if the number is a positive number, the additive inverse will be the negative value of the same number and if the original number is a negative number, the additive inverse will be the positive value of the same number.

Therefore, the additive inverse of 1/2 is -1/2.

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
