Find the solution to the system of equations given below using elimination by addition. 5x + 20y = 60
x + 3y = 9

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.

i think it is 70
