Which equation shows one of the steps jamal could have taken to complete the square?

we can't use the square root initially since we do not have c-value. But we can add a constant d to both sides of the equation to get a new equivalent equation ...

the three one is right.

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.
