Describe how the range of a data set can help describe its variability.

katovenus [111]

Answer:

The range is defined as the difference between the term with the highest value and the term with the lowest value. This statistic is used to measure the variability of a series of data because it provides information on how far apart the values of a tail of the distribution are from the values at the other end of the tail.

Imagine that you manufacture a type of spare part for cars that must have a measurement of 10 cm with a margin of error of 1 cm.

This is:

10 ± 1 cm

Then you expect your manufacturing process to produce pieces with identical dimensions, that is, with little variability.

If you randomly select a sample of n pieces and measure them, the variability is expected to be low, so that your process is of quality, then expect a low range preferably less than 1 cm.

{10, 10.1, 10.5, 9.8, 9,6, 10.2} Range= 10.5 - 9.6 = 0.9 cm low variability

But if you find that the range is up to 8 cm, this would mean that not all pieces measure around 10 cm, it means that the variability of the measurements is high.

{14, 12, 11, 8, 7, 11, 12, 15} Range = 15 - 7 = 8 cm high variability

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

$|z|=\sqrt{34}$

Subtract. (2p^2+q)-(p^2+q) Is the answer P^2 P^2+2q P^2-2q 3p^2

Fofino [41]

Answer:

-p5q2 - p3q5 + 2p3 + 2pq2 + 2q3

____________________________

p3q2

Step-by-step explanation:

Simplify ——

Equation at the end of step 1 :

(p+q) 2

(((2•—————)-(q3))+——)-p2

(p3) q2

Step 2 :

p + q

Simplify —————

p3 (p + q) 2

(((2 • ———————) - q3) + ——) - p2

p3 q2

Step 3 : 2 • (p + q) 2

((——————————— - q3) + ——) - p2

p3 q2 q3 q3 • p3

q3 = —— = ———————

1 p3
