Answer:
Step-by-step explanation:
1. X/2 when x = 1/2
Putting value of x in the equation
1/2 /2 = 0.25
2. 2x2 - 8 when x = 3
2(3)2 - 8
= 2(9) - 8
= 18 - 8 = 10
3. 4(x - 7)3 + 5 when x = 9
4 (x3 - 21x2 + 147x - 343) + 5
Putting value of x
4((9)3 - 21(9)2 + 147(9) - 343) + 5
4(729 - 1701 + 1323 - 343) + 5
4(8) + 5
= 32 + 5 = 37
Answer:
1. 0.25
2. 208
3. 517
Step-by-step explanation:
Number 1.
0.5/2
= 0.25
number 2.
2(3)^3-8
6^3 - 8
216-8
= 208
Number 3.
4(9-7)^3 +5
4(2)^3+5
8^3+5
= 517

given that there is one possible outlier. if the outlier was removed from the data set, how would it effect the measures of central tendency? {8, 73, 74, 75, 79, 85, 85, 92, 94}

O Both mean and median increase
O Both mean and median decrease
Answers
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!

For the three-part question that follows, provide your answer to each question in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C.
Part A: A homeowner wants to purchase new carpet for his rectangular living room, which is 8 feet wide and 12 feet long. What is the area of the carpet needed to completely cover the floor of the living room? Choose the correct answer.
A. 40 feet
B. 40 square feet
C. 96 square feet
D. 96 feet
Part B: Bianca wants to wrap a gift for her sister. The gift is in a box with a length of 10 inches, height of 2 inches, and depth of 3 inches. What is the minimum amount of wrapping paper Bianca needs to completely cover the box?
Part C: Greg had a rectangular vegetable garden that was 4 feet wide by 5 feet long. He increased the length of his garden by 2 feet and doubled the width. How many square feet larger is the area of his new garden compared to the area of his old garden? In a short paragraph, explain your answer in your own words.
Answers
part b: 60 inches
part c: 36 square feet
explanation: I multiplied 4 and 5 because area = l•w meaning the garden was originally 20 square feet. I then doubled the making it 8 and added two feet to the length making it 7 feet. Since area equals l•w i multiplied 8 and 7 getting 56 square feet. Since the question asked, “how many square feet larger,” I subtracted the new area, 56 square feet, by the old one, 20 square feet, and got 36 square feet.

Answer:
(47xy)/(6√3)
Step-by-step explanation:
A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.
A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.
A quotient is formed when a first value is divided by a second value.
Here is the quotient of our variable term and our constant:

Answers
Answer:
3
Step-by-step explanation:
The line 3 is not a line of symmetry.
What is Line of Symmetry?Line of symmetry of a figure or a shape is the line which divides the figure or shape in to equal and symmetrical parts.
This line is also called as axis of symmetry.
It is sometimes also called as mirror line since the line divides in to parts which looks like mirror images.
Given is a shape of a triangle.
There are 4 lines drawn.
Of these, 3 lines are drawn from a vertex of the triangle to the middle point of the opposite side, which divides the triangle in to two equal triangles.
So these lines are lines of symmetry.
But line 3 does not divide the triangle in to equal parts.
So it is not line of symmetry.
Hence line 3 is not a line of symmetry.

SA = 2xh + 2pi * r ^ 2
SA = 2pi * (8) * (4) + 2pi * r ^ 2
SA = 2pi * (32) + 2pi * (8 ^ 2)

SA = pi(64) + pi(128)
SA = pi(192)
