The Range Rule of Thumb roughly estimates the standard deviation of a data set as _______.

maw [93]

Answer:

Option A)

$s = \dfrac{\text{Range}}{4}$

Step-by-step explanation:

Range Rule of Thumb

The range Rule of thumb states that the range is four times the standard deviation.
The standard deviation is a measure of dispersion.

$\text{Range = Maximum - Minimum}\\\text{s: Standard Deviation}\\\text{Range rule of Thumb:}\\\text{Range} = 4\times s\\\\s = \dfrac{\text{Maximum - Minimum}}{4}$

Thus, the correct answer is

$s = \dfrac{\text{Range}}{4}$

What is the equation of the axis of symmetry for this function? H(x) = -X2 + 10x - 11 x = -5 0 x= -10 x = 5 x = 10

siniylev [52]

Given:

The equation of a quadratic function is:

$H(x)=-x^2+10x-11$

To find:

The equation of the axis of symmetry for the given function.

Solution:

If a quadratic function is $f(x)=ax^2+bx+c$ , then the equation of the axis of symmetry is:

$x=-\dfrac{b}{2a}$ ...(i)

We have,

$H(x)=-x^2+10x-11$

Here, $a=-1,b=10,c=-11$ . So, the equation of axis of symmetry by using (i), is

$x=-\dfrac{10}{2(-1)}$

$x=-\dfrac{10}{-2}$

$x=5$

Therefore, the correct option is C.
