$\text{Consider the function}\\
\\
y=-3\left ( \frac{1}{4} \right )^x\\
\\
\text{now to evaluate the value of the function at }x=-3, \text{ we substitute}\\
x=-3 \text{ in the given function and solve further for y.}\\
\\
\text{so we get}\\
\\
y=-3\left ( \frac{1}{4} \right )^{-3}\\
\\
\text{now using the exponent property, }\left ( \frac{1}{a} \right )^{-m}=(a)^m, \text{ we get}\\
\\
y=-3(4)^{3}\\
\\
\Rightarrow y=-3(64)\\
\\
\Rightarrow y=-192$

so the value of the function at x=-3 is -192

Hi looking for help me

Answer:

In my own words:

Definition from search: parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel.

My definition: Two lines that are equally apart from start to end.

These are / / or | | or = or \ \

When the outliers are removed, how does the mean change?

vivado [14]

Q1 = (19 + 20)2 = 19.5
Q2 = 26
Q3 = (32 + 33)/2 = 32.5
IQR = 32.5 - 19.5 = 13
13 * 1.5 = 19.5

outliers are : 19.5 - 19.5 = 0...anything below 0
32.5 + 19.5 = 52...anything above 52

there are no outliers <====
