Me with this. a diver went 25.65 feet below the surface of the ocean, and then 16.5 feet further down, he then rose 12.45 feet. write and solve an expression.

−25.65−16.5+12.45

=−42.15+12.45

=−29.7

Hope this helps !!

step-by-step explanation:

f

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.
