Answer:

Variance, Range, Standard deviation, Inter-quartile range

Step-by-step explanation:

The most commonly used measure of variability in a data set include;

Variance and standard deviation - measures the variability of a data set about a fixed location, the mean. Variance is the square of the standard deviation.

Range - this is the difference between the largest and the smallest values in a data set.

Inter-quartile range is simply the difference between the third and the first quartile where the second quartile is the median.

Other measures include;

Downside semi-variance

Which ordered pair is in the solution set of 6x + 4y ≤ −2?

Nutka1998 [239]

Answer:

x≤ −2/3y + −1/3

Step-by-step explanation:

because...

Step 1: Add -4y to both sides.

6x + 4y + −4y ≤ −2+−4y

6x ≤ −4y −2

Step 2: Divide both sides by 6.

6x/6 ≤ $\frac{-4y-2}{6}$

x ≤ −2/3y + −1/3

Therefor, the answer is x≤ −2/3y + −1/3

Describe the nature of the roots for this equation

vitfil [10]

First, fint the roots of the equation $2x^2+5x-7=0.$

$D=5^2-4\cdot 2\cdot (-7)=25+56=81,\\\sqrt{D}=\sqrt{81}=9,\\ \\x_1=\dfrac{-5-9}{2\cdot 2}=-\dfrac{14}{4}=-3.5,\\ \\x_2=\dfrac{-5+9}{2\cdot 2}=\dfrac{4}{4}=1.$

2. You can see that this equation has two different real roots. Note that you can make this statement without finding roots, only knowing the value of discriminant: since D=81>0, then the equation has two different real roots.
