choose the correct answer to fill in the blank. an outlier is an observation which is less than iqr or greater than q3 ( )times iqr.
Outliers are any observations that fall more than 1.5 IQR below Q1 or more than 1.5 IQR above Q3.
Outliers:
While observing the data in the observations some of data may fall outside the general scope of the other observations. Such observations are called outliers.
Given,
An outlier is an observation which is less than IQR or greater than Q3 times IQR.
Here we need to find in Q1 and Q3 place variations.
When we use the IQR method of identifying outliers to set up a “fence” outside of Q1 and Q3. Any values which fall outside of the identified fence are considered outliers.
To build this fence we take 1.5 times the IQR and then subtract this value from Q1 and add this value to Q3.
Like,
IQR = (1.5 - Q1)
IQR = (1.5 + Q3)
This gives us the minimum and maximum fence posts that we compare each observation to.
Therefore, any observations that are more than 1.5 IQR below Q1 or more than 1.5 IQR above Q3 are considered outliers.

Provide three additional commonly used statistical measures for the characterization of data dispersion.
The three additional commonly used statistical measures for the characterization of data dispersion are: Standard Deviation, Interquartile Range and Range.
What is dispersion in statistics?Dispersion in statistics refers to how far the data deviates from the mean.When measures of central tendency are insufficient to explain the data, it is highly helpful. Consider the case where the mean is the same across two completely different datasets. Then, in order to explain the variation in the datasets, we employ metrics of dispersion.Now,
The most common examples of statistical metrics of dispersion include:
Standard Deviation: A measurement of how widely apart data are from the mean is the standard deviation. It is the most typical method of measuring dispersion.Interquartile Range: The middle 50% of observations are described by the interquartile range (IQR). The middle 50% of observations are widely separated if the interquartile range is big. Extreme values have no impact on it. Consequently, is helpful when the extreme values are not precisely recorded.Range: The range of data is the distance between the largest and smallest observation. It does not use all of the observations in a data collection and is particularly sensitive to outliers. Therefore, giving the minimum and maximum values rather than the range is more instructive.Hence, The three additional commonly used statistical measures for the characterization of data dispersion are: Standard Deviation, Interquartile Range and Range.

Answer:
f'(1) = -64
Step-by-step explanation:
To find f'(1), we will be finding the f'(x) first which means the first derivative of f(x), we can find the derivative by using chain rule to this function.
The formula of chain rule is:
[tex]\displaystyle f(u) = u^n \to f'(u) = nu^{n-1}\cdot u'[/tex]
In simple explanation, we derive normally (power rule) then multiply by the derivative of inside (u).
Applying the formula, we will have:
[tex]\displaystyle{f'(x)=4(x^2-3)^{4-1}\cdot (x^2-3)'}\\\\\displaystyle{f'(x)=4(x^2-3)^{3}\cdot 2x}\\\\\displaystyle{f'(x)=8x(x^2-3)^{3}}[/tex]
Substitute x = 1 in the f'(x):
[tex]\displaystyle{f'(1)=8(1)(1^2-3)^3}\\\\\displaystyle{f'(1)=8(1-3)^3}\\\\\displaystyle{f'(1)=8(-2)^3}\\\\\displaystyle{f'(1)=8(-8)}\\\\\displaystyle{f'(1)=-64}[/tex]

Explaining How to Use Linear Palls and
Imagine two lines intersect. How can the properties of
linear pairs and vertical angles help to determine the
angle measures created by the intersecting lines?
Explain.
Angles that are vertical are opposite ones that only have one common vertex.
Two sets of vertical angles result from the intersection of two lines.
When two lines intersect, we obtain two linear pairs, which are two angles that make a straight line.
Knowing one of the angles formed when two lines intersect enables us to determine that the vertical angle, which is the angle directly across from it, has the same measurement.
Additionally, we know that the angle next to it, which creates a linear pair, will be added to it (add to 180), allowing us to discover its measure by subtracting it from 180.
Since they are both vertical angles, the remaining missing angle will be the same as this supplementary angle.

is the chance of Tara being selected?
The probability or chance of Tara being selected is 1/29.
What is probability?Probability is the chance of happening something or the occurrence of something . We can also define the probability as the chance of occurring or the chance of selecting something from the total set of value. It is always ranges from 0 to 1 where 0 is minimum value and 1 is maximum value of probability.
Formula for probability is :
[tex]P(Event) =\frac{ Chance \ of \ occurring \ that \ event}{total \ occurance}[/tex]
where, the total occurrence is the sample space of our given data or we can say the total number of values in the sample space.
In the given question,
Chance of selecting Kenny = 1 / 29
=> P(Kenny is selected) = 1/29
That means sample space consist of 29 values.
Now, P(Tara is selected) = 1 / sample space

What are the ordered pairs of the solutions for this system of equations? y=x^2-2x+3
y=-5x + 1
The ordered pairs of the solutions for this system of equations is (-2,11) and (-1,6)
Two integers written in a certain order make up an ordered pair. As a result, we may define an ordered pair as a pair of components that appear in brackets and in a specific order.
These equations are composed of a line and a parabola. The intersection points between them must be located:
[tex]y=x^2-2x+3[/tex]
y=-5x+1
Thus,
[tex]x^2-2x+3=-5x+1[/tex]
[tex]x^2-2x+5x+3-1=0[/tex]
[tex]x^2+3x+2=0[/tex]
[tex]x^2+x+2x+2=0[/tex]
[tex]x(x+1)+2(x+1)=0[/tex]
x+2=0, x=-2
x+1=0, x=-1
Since the quadratic expression may be factored out, the following x-values represent the system's solution:
x=-2 and x=-1
Now, we may obtain the corresponding y values using either of the system's original equations. We decide to use a linear equation as an illustration:
When x =-2,
y=11
x=-1,
y=6

What is rate of change of a function?To determine the slope of a graphed function, we use the average rate of change formula: Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in measurable parameters like average speed or average velocity calls for the knowledge of the average rate of change.Now,
Given:
For Function A, y = 9x + 4For Function B, rate of change = 4 and y intercept = 4To find: The number of times the rate of change of function A is, as compared to the rate of change of function B.
Finding:
According to the information given,
Rate of change = 3, i.e., b = 3 for function By- intercept = 4, i.e., c = 4Thus, by the slope-intercept form, given by: y = bx + c, the rate of change for function B is given by:
y = 3x + 4

The likelihood of something occurring is measured in terms of probability, which is based on ______.
The possibility that something will occur, prior measures, and conventional objective measurements all influence the likelihood that something will occur.
What is probability and what types are there in total?
The study of probability is a field of mathematics that determines the probability of an event occurring, which is represented by a number between 1 and 0. When an event has a probability of 1, it can be said to be a certainty. For instance, if the coin lands flat, the likelihood that it will come up "heads or tails" is 1. There are no other possible outcomes. A probability of .5 indicates that there is an equal chance that an event will occur or not.
Probability can be quantitatively represented in the simplest form as follows: the total number of possible outcomes multiplied by the ratio of the number of occurrences of a targeted event divided by the sum of the occurrences and failures of occurrences:
P(a) = P(a)/[P(a) + P(b)]

Part B:

Step-by-step explanation:
Let's assume she will stick with 10 litres in total for her mixture. (Maybe that's the size of her container.)
Let the volume of 5% by x litres.
Therefore the volume of 40% will equal 10 - x.
Reason: 10 litres total, if we use 2 litres of the one, we'll use 8 litres of the other. Get it?
Moving along...
So:
(0.20)(10) = (0.05)(x) + (0.40)(10 - x)
Now we solve the equation...
2 = 0.05x + 4 - 0.4x
2 - 4 = - 0.35x
-2 = -0.35x
let's multiply both sides by 100 to get rid of the decimal
-200 = -35x
x = 200/35
x = 5.7 litres (volume of 5% solution needed)
volume of 40% = 10 - 5.7 = 4.3 litres
