Calculate the volume.
300 km^3
330km^3
270km^3
540km^3

300km^3=27000000cubickilometers

330km^3=35937000cubickilometers

220km^3=19683000cubickilometers

540km^3=157464000cubickilometers

Step-by-step explanation:

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.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
