The median of the data set is 81. What number is missing?<br><br> 82, 87, _, 77, 70, 80, 88

mina [271]

Median is the middle number.
Rearrange the numbers to smallest to biggest.
70, 77, 80, _, 82, 87, 88
If the median of the data set is 81 the middle number needs to be 81.
So the missing number is 81.
70, 77, 80, 81, 82, 87, 88

Rewrite square root of -49 -4 in complex number notation please help

SVEN [57.7K]

Note that if $i^2=-1$ than $i=\sqrt{-1}$ ,

Also note that $\sqrt{ab}=\sqrt{a}\sqrt{b}$

So we have,

$\sqrt{-49}=\sqrt{-1}\sqrt{49}=\boxed{7i}$

and,

$\sqrt{-4}=\sqrt{-1}\sqrt{4}=\boxed{2i}$

Hope this helps.
