Answer:

$\Huge \boxed{\mathrm{2 \ cm }}$

Step-by-step explanation:

$\sf Volume \ of \ cuboid= length \cdot width \cdot height$

The width is 8.5 cm.

The height is 13 cm.

The volume is 221 cm³.

$221 = l \cdot 8.5 \cdot 13$

Solving for $l$

$221=l \cdot 110.5$

Dividing both sides by 110.5

$2=l$

The length is 2 cm.

S the standard deviation of the sample a good estimate of the variation of salaries of tv personalities in general?

ziro4ka [17]

The answer is No because the sample is not representative of the whole population. The standard deviation of the sample is not a good estimate of the variation of the salaries of the TV personalities in general because a single sample is not counted as a whole. Standard Deviation is a quantity that is calculated to indicate the extent of deviation of the population or group as a whole. Standard deviation also represented by the symbol σ means sigma in Greek letter or s in Latin letter. It is also the measurement of a set of data values that are used to quantify the amount of variation.

THE X-INTERCEPT OF THE LINE X=3.5 IS

tiny-mole [99]

Well.. for the equation x= 3.5, let's take a look at its values
$\bf \begin{array}{lrlll}
x&y\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
3.5&-\infty\\
3.5&-1,000,000\\
3.5&-1,000\\
3.5&-100\\
3.5&-10\\
3.5&-1\\
3.5&0\\
3.5&1\\
3.5&10\\
3.5&100\\
3.5&1,000\\
3.5&1,000,000\\
3.5&1+\infty
\end{array}$

so.. notice.. no matter what "y" is, "x" will always be 3.5,
so is really just a horizontal line, thus, look at the picture below
