The variability measures the closeness of the individual data provided. So, the most reliable sampling is the one with the lowest variability. 

For this case, the question with the lowest sampling variability is question 3. Therefore, we can conclude that the answers to which of the questions are most reliable is question 3.

Which expression is equivalent to 5!<br> 5^4*3^2<br> 5-4-3-2-1<br> 5.4.3-2.1<br> 5+4+3+2+1<br> 5.1
baherus [9]
The first one is like 5x5x5x5 which is 625 multiplied by 3x3 which is 9 and together the product will be 5,625.

The second one is 5-4 which is 1-3 which is -2 - 2 = -4 - 1 which is -5 so it’s not it because it’s the opposite of the number we need to find.

The third one is kind of messed up because there’s no such thing as 5.4.3 so sorry I can’t do that one.

The fourth one is 15 because you basically add the numbers up.

And the fifth is not 5. It’s 5.1 so that’s not it either.

So I’m sorry I can’t find the answer but at least I have you some background :/

S_A_V [24]

Answer:

x4

\{x\in \mathbb{R}|  \:\left(-\infty \:,\:-4\right)\cup \left(4,\:\infty \:\right)    \}

Step-by-step explanation:

x^2>16

x\sqrt{16}

x4

The interval notation will be:

\{x\in \mathbb{R}|  \:\left(-\infty \:,\:-4\right)\cup \left(4,\:\infty \:\right)    \}

The contrary,

x^2

is -4
