Answer:

$5\sqrt{7}$

Step-by-step explanation:

$\frac{30\sqrt{14} }{6\sqrt{2} }$

Cancel out 6 in both numerator and denominator.

$\frac{5\sqrt{14} }{\sqrt{2} }$ Rationalize the denominator of $\frac{5\sqrt{14} }{\sqrt{2} }$ by multiplying the numerator and denominator by $\sqrt{2}$ .

$\frac{5\sqrt{14}\sqrt{2} }{(\sqrt{2})^{2} }$

The square of $\sqrt{2}$ is 2

Factor 14=2 × 7. Rewrite the square root of the product $\sqrt{2x7}$ as the product of square roots $\sqrt{2}\sqrt{7}$ .

$\frac{5\sqrt{2}\sqrt{7}\sqrt{2} }{2}$

Multiply $\sqrt{2}$ and $\sqrt{2}$ to get 2.

$\frac{5x2\sqrt{7} }{2}$

Cancel out 2 and 2.

$5\sqrt{7}$

Hope it helps and have a great day! =D

{1, 4, 9, 4, 10, 8, 42} What is the best measure of center for this data set?

bonufazy [111]

1, 4, 9, 4, 10, 8, 42

Put this into order.

1, 4, 4, 8, 10, 42

It would most definitely not be the mode, because there is an outlier, and it wouldn't be the median, because once again, there is an outlier.

So, that leaves you with the mean.

The mean would measure this the best because it'll represent it the best. It is also the only one that'll fully make sense.

So, your answer is : The mean.
