Solution:

Note that:

R = 6 in
Formula of area of circle: πr²
π = 3.14

Substituting the radius in the formula.

Formula of area of circle: πr²
=> Formula of area of circle: 3.14 x 6²

Finding the area:

=> Formula of area of circle: 3.14 x 36
=> Formula of area of circle: 113.04 in²

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

$s=\sqrt{s^2}$

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
