Step-by-step explanation:
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 Mean increases median decreases
O Mean decreases median increases
O Both mean and median increase
O Both mean and median decrease
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.

Which is NOT a line of symmetry (please help)
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.

An urn contain 2 white marbles, 3 green marbles, and 5 red marbles. A marble is drawn and then replaced. Then a second marble is drawn. What is probability that the first marble was white and the second was green?
Answer:
1/5
Step-by-step explanation:
To find this you would need to multiply the probability of pulling a white marble to the probability of pulling out a green marble.
1)First you would need the probability of pulling out a white marble. There are 10 marbles in total and out of those 2 are white. So the probability of pulling out a white marble would be 2/10. If you simplify that you would get 1/5 for the probability of pulling out a white marble.
2)Next, you would find the probability of pulling out a green marble. Using the same process that we used to find the probability of pulling out a white marble, we would find the answer to be 3/10. All that we did here was green marbles/total marbles. By filling that in we got 3/10 for the probability of pulling out a green marble.
3)Now all that is left is doing probability of pulling a white marble × probability of pulling out a green marble. This would be 1/5 × 3/10. After solving the answer would be 3/15 which we would simplify down to 1/5 as our final answer.

d x = 54
Answer:
I believe x = 12
Step-by-step explanation:
If the triangles were similar then they would have the same angle measures.
Steps:
Add angle K and L: 90 + 54 = 144
Subtract the added angles from 180 to find angle J: 180 - 144 = 36
Angle J is similar to angle X so, divide 36 by 3: 36/3 = 12
x = 12

Determine the measures of the angles if they are both vertical and supplementary.
Answer:
90, 90
Step-by-step explanation:
Since the two angles are vertical, it means that they must have the same measure. Because they are supplementary, that means they add to 180. Thus, the two angles must be 90 and 90.
