When converting English phrases into mathematical expressions/equations, we do things from left to right. That is why it's 4 - 20 instead of 20 - 4.

This rule is applied to division as well.

Which set of population data is the least dispersed from its mean? 2, 3, 2, 9 4, 0, 4, 0 6, 2, 2, 2 9, 3, 5, 3.

exis [7]

The set of data 6, 2, 2, 2 will have the least dispersion from its mean.

From four sets of data, we take the mean of 6,2,2,2

$\rm mean =\dfrac{ Sum \ of\ data}{Number \ of\ data}$

So the mean will be

$\rm mean =\dfrac{ 6+2+2+2}{4}=\dfrac{12}{4} =3$

So the mean of the data (6,2,2,2) is 3 which has the least dispersion from its every data as compared to the other data

Thus the set of data 6, 2, 2, 2 will have the least dispersion from their mean.

What is the slope of the line containing (-2, 5) and (4,-4)?

Pachacha [2.7K]

Answer:

Option C is correct.

Step-by-step explanation:

<h2> $slope \: = \: \frac{y2 - y1}{x2 - x1}$ </h2><h3> $= \frac{ - 4 - (5)}{4 - (2)}$ </h3><h3> $= \frac{ - 9}{4 + 2}$ </h3><h3> $= \frac{ - 9}{6}$ </h3><h3> $= \frac{3( - 3)}{3 - 2}$ </h3><h3> $= - \frac{3}{2}$ </h3><h3>Hope it is helpful....</h3>
