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.

<h3 /><h3>What will be the mean?</h3>

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.

If z=3−5i, find |z|.
geniusboy [140]

Answer:

Step-by-step explanation:

The absolute value of z is the distance between the point graphed from the complex number and the origin on a complex plane.  In a complex plane, the x axis is replaced by R, real numbers, and the y axis is replaced by i, the complex part of the complex number.  Our real number is positive 3 and the complex number is -5, so we go to the right 3 and then down 5 and make a point.  Connect that point to the origin and then connect the point to the x axis at 3 to construct a right triangle that has a base of 3 and a length of -5.  To find the distance of the point to the origin is to find the length of the hypotenuse of that right triangle using Pythagorean's Theorem.  Therefore:

|z|=\sqrt{(3)^2+(-5)^2} and

|z|=\sqrt{9+25} and

|z|=\sqrt{34}
