Answer:
Some measures I believe you are talking about are mean, median, mode, and range.
Mean is the average of all values. This is found by adding up all numbers and dividing by the amount of numbers. Outliers greatly affect and "throw off" the mean, making it inaccurate at calculating the average without an outlier.
Example:
1, 2, 4, 6, 10
(1 + 2 + 4 + 6 + 10)/5 = mean = 4.6
1, 2, 4, 6
(1 + 2 + 4 + 6)/4 = mean = 3.25
Because of this, mean does change when adding and removing outliers, and is therefor not the answer.
Median is the middle of the data. This is found by ordering the values in the data set from least to greatest (or greatest to least, either one works) and finding the number in the center of all the values. If there were an outlier, the median wouldn't be skewed as the mean is by outliers, but it would change.
Example:
1, 2, 4, 6, 10 Median = 4
1, 2, 4, 6 Median = 3
So median is not the answer, because it is affected by adding and removing outliers.
Mode is the value in a data set that appears the most. Outliers are numbers that are significantly lower or higher than most or all of the other numbers in a data set. Because of this, there can't be more outliers than other numbers, so it is impossible for the mode to be an outlier.
Example:
1, 1, 1, 2, 3, 4, 4, 86 Mode = 1
1, 1, 1, 2, 3, 4, 4 Mode = 1
This means the mode is not affected by adding and removing outliers.
Mode is a possible answer, but let's take a look at range before coming to a conclusion.
Range is the spread of values in a data set. In other words, the difference between the highest and lowest value. A high range can signal a possible outlier is present.
Example:
1, 2, 4, 6, 10
10 - 1 = highest value - lowest value = range = 9
1, 2, 4, 6
6 - 1 = highest value - lowest value = range = 5
The range is certainly affected by outliers, so it is not the answer.
Out of mean, median, mode, and range, the answer to this question is mode.
If an outlier is removed, mode will not change.
Hope this helps!

Which list could represent the four angle measures of a quadrilateral if one angle measures 125°?
A. 10°, 10°, 125°, 125°
B. 15°, 15°, 25°, 125°
C. 15°, 15°, 115, 125°
D. 55°, 55°, 125°, 125°
Answer: D
Step-by-step explanation:
The sum of the interior angles of a quadrilateral is 360°.
55+55+125+125=360
Answer:
D. 55, 55, 125, 125
Step-by-step explanation:
To solve this problem we first need to know what the total degrees of a 4 angle quadrilateral is. The answer to this is 360°. Knowing this, we need to figure out which combination of numbers adds up to 360. To do this, I go through the list and check all of the options.
A.) 10+10+125+125=270
B.) 15+15+25+125=180
C.) 15+15+115+125=270
D.) 55+55+125+125=360

Question 5

Answer:
D) 27
Step-by-step explanation:
It's a rectangle so the opposite sides are congruent to each other.
Long Side:
6x + 6 = 42
subtract 6 from both sides:
6x = 36
divide both sides by 6:
x = 6
Short Side:
5y + 5 = 30
subtract 5 from both sides:
5y = 25
divide both sides by 5:
y = 5
The Equation:
2x + 3y
substitute in the values:
2(6) + 3(5)
do the multiplication:
12 + 15
add the values together:

a whole number by a unit fraction is the same as multiplying a whole number by the of the unit fraction.
Answer:
A whole number divided by a unit fraction is the same as multiplying a whole number by the inverse of the unit fraction.
Step-by-step explanation:
Given
[tex]8 \div \frac{1}{5} = 40[/tex]
[tex]8 * 5 = 40[/tex]
Required
Explain why both expressions are correct
No dropdown to select from. So, I will provide a general solution.
When a number is divided by a fraction.
Take for instance:
[tex]8 \div \frac{1}{5}[/tex]
The above can be expressed as the product of the number and the inverse of the fraction.
The inverse of 1/5 is 5.
So, we have:
[tex]8 \div \frac{1}{5} = 8 * 5[/tex]
The result of the above expression is:
[tex]8 \div \frac{1}{5} = 8 * 5 = 40[/tex]

Find the area of the circle when C = 4π. Give your answer in terms of π.
Answer:
12.56
Step-by-step explanation:
So, the circumference will be 4(3.14), which is 12.56. So, now you can solve for area. By the way, the formula is: C = pi(d) (Just saying)
Anyways, A = pi(r)2. So, with the radius being half of the diameter, you will cut 4 in half. You are now ready to solve.
A = 3.14 (2) (2), which is 12.56 .

Did any get the answer for puzzle 3 in Pythagorean Theorem Digital Escape!
The formula relations given by Pythagorean theorem is used to
determine the lengths and area of the given squares and triangles.
Responses:
1. Area of a is H: 25
2. Length of b is I: 5
3. Length of C is A: 7.94
4. Area of d is B: 35.73
Where can the Pythagorean theorem be used to find the lengths and areas of a figure?1. Given;
The area of the side squares are; 9 m² and 16 m²
According to Pythagorean theorem, we have;
Area of square a = 9 m² + 16 m² = 25 m²
Area of a is H: 252. b² = Area of side square a
Therefore;
b = √(25 m²) = 5 m
Length of b is I: 53. Given;
Area of the squares adjacent to the hypotenuse side and a leg are;
144 m² and 81 m² respectively
According to Pythagorean theorem, we have;
C² = 144 m² - 81 m² = 63 m²
C = √(63 m²) = √(9 × 7 m²) = 3·√7 m ≈ 7.94 m
Length of C is A: 7.944. Area of triangle d = [tex]\frac{1}{2}[/tex] × √(81 m²) × 7.94 m ≈ 35.73 m
Area of d is B: 35.73Learn more about Pythagorean theorem here:

Answer:
What is factoring?
Factoring is finding what to multiply to find an expression. It is like splitting expression into a multiplication of simplified expression.
Why is it useful to try to factor out the GCF first when factoring?
Greatest common factor or GCF of two numbers is the largest number that divides evenly in both numbers, GCF works the same in polynomials, which divide the expression evenly .
Explain the relationship between factoring and multiplying polynomials. Give an example to help explain
Factoring take away the multiplication, to factorize a polynomial it means take apart what is multiplied. the best example is a²+b²+2ab ( multiplied)
factorize :(a+b)(a+b) take apart what is multiplied
Factor x^2-25, 3x^2-12x-15, and x^3+2x^2+3x+6
x²-25 =(x+5)(x-5)
3x²-12x-15 = 3(x²-4x-5) GCF=3
3(x-5)(x+1)
x³+2x²+3x+6 (x+2) common factor
(x+2)(x²+3)
What are the key features needed to graph a polynomial function?
the key features are the vertex, axis of symmetry, x and y intercept
Explain how to find these key features to sketch a rough graph of a polynomial function
parabola : y=ax²+bx+c
ex: 3x²-12x-15
find vertex (h,k)
h=-b/2a =-(-12)/2(3)=2
k=f(h)=f(2)=3(2)²-12(2)-15
k=12-24-15=-27
vertex=(2,-27)
x intercept is when the graph =0 (y=0)
y intercept when x=0 then y= the constant c and where the graph cross the y axis
axis of symmetry is the x of the vertex: is a line about which a parabola is symmetrical and vertical when the axis of symmetric is vertical.
Why would someone want to factor a polynomial? Provide real world examples of different questions we can answer or facts we can determine from factoring a polynomial.
factor a polynomial helps us understand more about equations,factoring helps us rewrite the polynomial into simpler expression.

A homeowner has a back yard and wants to turn it to garden beds so he can plant his vegetables, he wants to fill it with dirt he needs 240 cubic feet to fill it the length is 4 feet than the width , and the height is 4
solve:
length=W+4
height=1/3 w
V=length* width* height
240=(w+4)(w)(4)
351= 4w²+16w
4w²+16w-240=0
