In order to measure the dispersion of a random variable, look at its a. standard deviation. b. mean. c. expected value. d. avera

Sphinxa [80]

Answer:

a. standard deviation

Step-by-step explanation:

Dispersion is a measure of variability in a given data i.e the level or extent of spread of a data. This can easily be measured for a random variable by considering its standard deviation.

The standard deviation would show the extent to which each value is different from the mean. Thus showing the extent of the dispersion of variables.

Therefore, to measure the dispersion of a random variable, look at its standard deviation.

Which two steps should be used first in solving the system of equations

Inessa05 [86]

Answer:

The value of x , y using substitution method is 2 , 5

Step-by-step explanation:

Given as :

The two linear equation as

6 y - 4 x = 22 .......1

y + 2 x = 9

Let y = 9 - 2 x .......2

Now, using substitution method

Substitute the value of y from eq 2 into eq 1

i.e 6 × (9 - 2 x) - 4 x = 22

Or, 54 - 12 x - 4 x = 22

Or, 12 x + 4 x = 54 - 22

Or, 16 x = 32

∴ x = $\dfrac{32}{16}$

i.e x = 2

Now, Put the value of x into eq 2

∴ y = 9 - 2 x

So, y = 9 - 2 × 2

Or, y = 9 - 4

i.e y = 5

So, The value of x , y = 2 , 5

Hence, The value of x , y using substitution method is 2 , 5 Answer
