An outlier is a data point that is significantly different from the other data points in a set. It may or may not affect measures of central tendency. Outliers are not always the highest or lowest values in a data set.
Explanation:An outlier is a data point that is significantly different from the other data points in a set. It can be either higher or lower than the other values.
Outliers may be errors or abnormal data, or they may provide valuable insights into the population under study.
An outlier does not necessarily mean that it is a false data point. It needs to be examined closely to determine if it should be included in the analysis or not.
An outlier may or may not affect measures of central tendency, such as the mean, median, and mode.
It depends on the specific data set and the impact of the outlier on these measures. It is not always the highest or lowest value in a data set, as it can be any data point that deviates significantly from the rest.

You buy a bookshelf. The label on the box says the bookshelf is 5151 inches tall. How tall is it in feet?
1 foot = 12 inches
so 5151 inches divided by 12 = 429.25 feet tall
that is too tall for a normal house so hopefully you meant 51 inches
51 / 12 = 4.25 (4 1/4) feet tall
The probability that concert tickets are available by telephone is 0.91. for the same event, the probability that tickets are available through a web site is 0.96. assume that these two ways to buy tickets are independent. what is the probability that someone who tries to buy tickets both through the internet and by the telephone will obtain at least one ticket? round your answer to four decimal places (e.g. 98.7654).
Final answer:
The probability of obtaining at least one concert ticket through both the internet and by telephone is 0.9984.
Explanation:
The probability that someone who tries to buy tickets both through the internet and by telephone will obtain at least one ticket is 0.9984.
To calculate this, we first find the probability of not getting any tickets through either method: P(no tickets) = P(no tickets by phone) * P(no tickets online). Then, subtract this probability from 1 to get the probability of obtaining at least one ticket: P(at least one ticket) = 1 - P(no tickets).
Rotating a polygon in Quadrant II 270° clockwise is the same as
A) rotating it 90° clockwise.
B) rotating it 180° clockwise.
C) rotating it 90° counterclockwise.
D) rotating it 270° counterclockwise.
Answer:
90°
Step-by-step explanation:
Hi! A and B are definitely not the right answers, because that’s basically rotating it forward even more. Rotating a polygon in Quadrant II 370 degrees clockwise is like rotating it 99 degrees counterclockwise, because the next 90 degrees you were to rotate it, it would be in it’s original position. The answer is C.

72 square units
88 square units
44 square units
area = 13+9=22
22/2 = 11
11x 4 = 44 square units
Answer:
44 square units

Area of the trapezoid formula is [tex]\frac{base1 + base2}{2} \cdot height[/tex]
To find the base and the height we count the number of units in the graph
Base 1= 13
Base 2= 9 and height = 4
Now plug in all the values in the formula and find the area of the trapezoid
Area of the trapezoid=[tex]\frac{base1 + base2}{2} \cdot height[/tex]
=[tex]\frac{13+9}{2} \cdot 4[/tex]

Talia is packing a moving box. She has a square-framed poster with an area of 9 square feet. The cube-shaped box has a volume of 30 cubic feet. Will the posture lie flat in the box?
Answer: Yes, the posture will be lie flat in the box.
Step-by-step explanation:
since we have given that
Area of square framed poster = 9 sq. feet
Volume of cube shaped box = 30 cubic feet.
As we know the formula for "volume of cube":
[tex]Volume=30\\\\a^3=30\\\\a=\sqrt[3]{30}=3.10\ feet[/tex]
So, Area of cube shaped box would be
[tex]6a^2=6\times (3.1)^2=57.9\ ft^2[/tex]
Since the cube box is large enough so that the posture will lie flat in the box.
if a number is a natural number, then it is also a whole number? what is the Inverse, the Converse, the Contrapositive, and the Bi-Conditional? and what is the Truth value for each one?
The original statement, 'If a number is a natural number, then it is also a whole number' is true because every natural number falls into the set of whole numbers. However, its converse is not true, as whole numbers include 0, which is not a natural number, making the inverse and the bi-conditional false. The contrapositive of the statement is true, maintaining logical consistency.
Explanation:If a number is a natural number, then it is indeed also a whole number. The relationship between natural numbers and whole numbers is an inclusive one, where all natural numbers (1, 2, 3, ...) are also whole numbers (0, 1, 2, 3, ...). The original statement can be expressed in logical form as: If P, then Q, where P is 'a number is a natural number,' and Q is 'it is also a whole number.'
Here is how the other forms of the statement look:
The inverse negates both the hypothesis and the conclusion: If not P, then not Q. So, 'If a number is not a natural number, then it is not a whole number.'
The converse switches the hypothesis and the conclusion: If Q, then P. For our statement, 'If a number is a whole number, then it is also a natural number.'
The contrapositive negates and switches the hypothesis and conclusion: If not Q, then not P. Therefore, 'If a number is not a whole number, then it is not a natural number.'
The bi-conditional states that P if and only if Q: A number is a natural number if and only if it is a whole number.'
The truth value of the original statement is true since all natural numbers are whole numbers. However, the converse is not true because whole numbers also include 0, which is not a natural number. Consequently, the inverse and the bi-conditional are false. The contrapositive is true because if it is not a whole number, then it can't be a natural number (considering that whole numbers include all natural numbers).
What is the simplified form of cos C ?
A. √2/2
B. 1
C. √2
D. √5/2
The simplified form of cos C is sqrt(2)/2.
What is cos ?"Cos is the cosine function of a right triangle in trigonometry. Cos function is the ratio of adjacent side and hypotenuse. It helps us to find the length of the sides of the triangle, irrespective of given angle.
Suppose we have a right triangle and α is the angle between adjacent side and hypotenuse, then as per the cos function, we can write
Cos α = Adjacent Side/Hypotenuse"
Here, given the base of the triangle is = 5
and hypotenuse is = 5sqrt2
So, [tex]cos C = 5/5\sqrt2 = 1/\sqrt2[/tex]
Multiplying both numerator and denominator by sqrt2
We get [tex]\sqrt2/2[/tex].
Hence, the value of cos C is [tex]\sqrt2/2[/tex]

Which graph represents the solution set of the system of inequalities?
{−2x+y≤4
y>x+2
The correct graph is:
First graph
Step-by-step explanation:The first inequality is:
[tex]-2x+y\leq 4[/tex]
The graph of this inequality is a straight solid line ( since the inequality is a inequality with a equality sign i.e. not strict ) which passes through (-2,0) and (0,4) and the shaded region is towards the origin as it passes the zero point test.
The second inequality is:
[tex]y>x+2[/tex]
is a dotted straight line (since the inequality is strict) which passes through (-2,0) and (0,2) and the shaded region is away from the origin as it fails the zero point test.
Hence, the correct graph is the first graph.

A hose fills a tank at a rate of 20 gallons per minute.
What is the rate in liters per hour?
(1 gallon ≈ 3.79 liters)
Answer:
[tex]\frac{4548}{1}[/tex] liters per hour.
Step-by-step explanation:
Given : A hose fills a tank at a rate of 20 gallons per minute.
To find : What is the rate in liters per hour?
Solution : We have given
A tank can fill hose in 1 minute = 20 gallon .
1 gallon = 3.79 liters.
20 gallon = 20 * 3.79 = 75.8 liters.
20 gallon = 75 .8 liters.
So,
A tank can fill hose in 1 minute = 75.8 liters.
A tank can fill hose in 60 minute = 75.8 * 60 liters = 4548 liters.
A tank can fill hose in 1 hour = 4548 liters.
Rate = [tex]\frac{4548}{1}[/tex] liters per hour.
Therefore, [tex]\frac{4548}{1}[/tex] liters per hour.
