Which statement is true about the graphed function?

Semmy [17]

A function is positive if it lies above the x axis.

This function is positive before x = -4, i.e. over the interval $(-\infty, -4)$

It is negative elsewhere, i.e. over the interval $(-4, \infty)$

So, the only correct option is the second one.

Standard deviation 12,16,22,23,34,44,46,47,48,64,67,73,83,89, round to nearest tenth

RideAnS [48]

Answer: 23.9

Step-by-step explanation:

1. First, you must calculate the mean, as following:

$\frac{12+16+22+23+34+44+46+47+48+64+67+73+83+89}{14}=47.71$

2. Now, you should substract the means obtained to every single number of the set and then square it. Add all of them:

$(12-47.71)^{2}+(16-47.71)^{2}+(22-47.71)^{2}+(23-47.71)^{2}+(34-47.71)^{2}+(44-47.71)^{2}+(46-47.71)^{2}+(47-47.71)^{2}+(48-47.71)^{2}+(64-47.71)^{2}+(67-47.71)^{2}+(73-47.71)^{2}+(83-47.71)^{2}+(89-47.71)^{2}=7984.86$

3. The mean of this is:

$\frac{7984.8574}{14}=570.35$

4. The square root of this result is:

$\sqrt{2.52}=23.88$

5. To the nearest tenth, the result is: 23.9
