Answer:

The smallest model - bottom right - in the question diagram represents \sqrt[3]{64}=4.

Step-by-step explanation:

Considering the radical expression

\sqrt[3]{64}

Lets simply this radical expression first

As

\sqrt[3]{64}

\mathrm{Factor\:the\:number:\:}\:64=4^3

=\sqrt[3]{4^3}

\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a,\:\quad \:a\ge 0

\sqrt[3]{4^3}=4

      =4

Therefore, \sqrt[3]{64}=4

Now, as we can determine that \sqrt[3]{64}=4. So, the smallest model in the question diagram represents \sqrt[3]{64}=4 as each face of the cube of the smallest model in the diagram - bottom right - has 4 squares.

Therefore, the smallest model - bottom right - in the question diagram represents \sqrt[3]{64}=4.

Keywords: square cube root, radical expression

I think the answer is A is this correct? thank you!
likoan [24]

Answer:

x^2 = a/b (option a)

Step-by-step explanation:

If we have square root at the top and bottom then we take single square root with fraction inside

To remove square root we take square on both sides because square and square root will get cancelled

x^2 = a/b is true

What happens when the sample size of an online poll is increased?
zaharov [31]

Answer:

As the sample size increases the standard deviation of the sample decreases and hence the variability of the sample decreases.

Hence the second option is the correct option.

Step-by-step explanation:

i) let the standard deviation of the population be given by σ.

ii) for sample taken from among the population of size n the standard deviation of the sample becomes \frac{\sigma}{\sqrt{n} } and so we can see that for the sample the standard deviation of the sample is less than the standard deviation of the sample.

iii) As the sample size increases we can say that the standard deviation of the sample decreases.

iv) the variance , or variability, of a sample is equal to the square of the standard deviation of the sample.

therefore as the sample size increases the standard deviation of the sample decreases and hence the variability of the sample decreases.
