A step function, as it decreases once every 15 days and remains constant for periods in between.

What is the term for a point that varies greatly from all other data points

xenn [34]

The term for a point that varies greatly from all other data points is known as an <u>OUTLIER</u>

<u></u>

Explanation:

An outlier is a data point that differs significantly from other observations. An outlier may be due to variability in the measurement or it may indicate experimental error.
An outlier can cause serious problems in statistical analyses.
An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. In a sense, this definition leaves it up to the analyst to decide what will be considered abnormal.
A point that falls outside the data set's inner fences is classified as a minor outlier, while one that falls outside the outer fences is classified as a major outlier.
The data here appear to come from a linear model with a given slope and variation except for the outlier which appears to have been generated from some other model.
Outliers can occur by chance in any distribution, but they often indicate either measurement error or that the population has a heavy-tailed distribution.

Find the range of the following piecewise function.

mash [69]

Answer:

$\huge\boxed{[-5;\ -2)\ \cup\ [3;\ 13)}$

Step-by-step explanation:

The following piecewise functions are linear functions. The graph of any of them is a line segment.

We just need to calculate the value of the function at each end specified in the brace.

$y=3x-2\ \text{if}\ -1\leq x$

Substitute x =-1 and x = 0:

$x=-1\\y=3(-1)-2=-3-2=-5\\\\x=0\\y=3(0)-2=0-2=-2$

Range of this piece is [-5; -2)

$y=2x+3\ \text{if}\ 0\leq x$

Substitute x =0and x = 5:

$x=0\\y=2(0)+3=0+3=3\\\\x=5\\y=2(5)+3=10+3=13$

Range of this piece is [3; 13)

Therefore the range of the following piecewise function is:

$[-5;\ -2)\ \cup\ [3;\ 13)$

Look at the picture.

Simplify this equation<br> -5x+7>22

Lana71 [14]

Answer:

<h2>x < - 3</h2>

Step-by-step explanation:

$- 5x + 7 > 22$

Move 7 to the other side of the inequality

$- 5x > 22 - 7 \\ - 5x > 15$

Divide both sides by - 5

$\frac{ - 5x}{5} > - \frac{15}{5} \\ x > - 3$

Reverse the sign

We have the final answer as

<h3>x < - 3</h3>

Hope this helps you
