Which ordered pair in the form (a, b) is a solution of this equation?

Evgen [1.6K]

3a - 4b = 21

check (-2 , -3)

3(-2) -4(-3) =21

-6 +12 = 21

6 does not = 21 so NO

check (0 , 7)

3(0) -4(7) =21

0-28=21

-28 does not equal 21 so NO

check (-3 , -2)

3(-3) -4(-2) =21

-9 +8 = 21

1 does not = 21 so NO

check (7 , 0)

3(7) -4(0) =21

21 = 21

Choice D

If Professor Wilson found that the test scores of his students had a variance of 4.4, what is the standard deviation? Type a num

malfutka [58]

Answer:

The standard deviation will be: 2.1

Step-by-step explanation:

We know that standard deviation is basically the square root of variance.

Using the formula to calculate the standard deviation

$s=\sqrt{s^2}$

As

The variance = s² = 4.4

so the standard deviation can be calculated as:

standard deviation $=\sqrt{s^2}$

$=\sqrt{\left(4.4\right)^}$

$=2.1$

Therefore, the standard deviation will be: 2.1
