Answer:

$5\sqrt{8}$

$24\sqrt{3}$

Step-by-step explanation:

To simplify the square roots, break the number under the square root into factors. Any factors which are perfect squares may be simplified to outside the square root.

$\sqrt{200}=\sqrt{25*8} =\sqrt{25}*\sqrt{8}= 5*\sqrt{8} =5\sqrt{8}$

and

$4\sqrt{108}=4\sqrt{27*4} =4*\sqrt{27}*\sqrt{4}=4* \sqrt{9} *\sqrt{4}*\sqrt{3} =4*3*2*\sqrt{3}=24\sqrt{3}$

Answer:

Option B) 9.1

Step-by-step explanation:

We are given the following in the question:

Average score = 490.4

Standard deviation = 63.7

Sample size, n = 49

Formula:

$=\dfrac{\sigma}{\sqrt{n}}$

Putting values, we get,

Standard error =

$=\dfrac{\sigma}{\sqrt{n}} = \dfrac{63.7}{\sqrt{49}} = 9.1$

Thus, the correct answer is

Option B) 9.1
