A , and C

Step-by-step explanation:

A. 2.3+(-2.3) ➡ 2.3 -2.3 = 0 so this option is correct

B.-3.7+(-4.1) ➡ -3.7 - 4.1 = -7.8 so this option isn't correct

C.-2.6-(-12/4) ➡-2.6 + 3 = 0.4 this option is also correct

D. (5/2)+(-2.5) ➡ 5/2 -5/2 = 0 this one would be undefined because we can't divide 0 by 2 or any other rational numbers

E.72-(-100) ➡72+100= 172 is positive not negative therefore this option is incorrect

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
