Answer:
100
Step-by-step explanation:
Last year：
boy：girl
1 ： 2
This year：
+70
boy：girl
1×4 ：2×3
4 ：6
70=7
so，1=10
All members：10×10=100（because（4+6）=10）

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.
Hope this helps!
Step-by-step explanation:
If you spin the spinner 400 times, how many times can you expect it to land on an even number?
please solve with explaining what you did too, i don’t get this.
Answer:
You would expect the arrow to land on an even number about 25% of the time.
Step-by-step explanation:
In the sector labeled 1 you would expect it to land on it 50% of the time because that sector takes up 50% of the spinner. For the rest of the sectors, you would take to the remaining 50% and divide it by four for the four other sectors on the spinner. 50 ÷ 4 = 12.5 Then you would take the number of even numbers there are on the spinner, which is two in the case, and add those percentages together. 12.5 + 12.5 = 25

Answer:
Wendy is filling in party goodie bags with toy cars and helicopters. There are 56 toy cars and 77 helicopters. Each bag must only have either toy car or helicopter - there is no mixing of toys.
Each bag must have the same number of toy cars in it.
Each bag must have the same number of toy helicopter in it.
All bags must have the same number of toys in it.
a) How many bags will contain toy cars?
b) How many bags will contain toy helicopters?
-------------------------------------------------------------------------------------------------------------
Answer:
Think of highest common factor of 56 and 77
Both numbers are divisible by 1, 2, and 7 and the highest common factor is 7
56 ÷ 7 = 8
77 ÷ 7 = 11
There are 8 bags that contain equal numbers of toy cars and 11 bags that contain equal number of helicopter toy

A coin is tossed then a letter from the word INCREDIBLE is chosen at rndom What is thr probablility of getting heads then a vowel?
Answer: 1/5
Step-by-step explanation: the probability that you get heads on the coin is 1/2 and the probability for getting a vowel out of incredible is 4/10 or simplified 2/5. So you multiply... 1/2 x 2/5 = 1/5

will give brainliest and 5 stars and thanks!
Answer:
600
Step-by-step explanation:
We require to find the total number of words, that is 100%
Given 15% = 90 words
Divide 90 by 15 to find 1% and multiply by 100 for total , that is
number of words = [tex]\frac{90}{15}[/tex] × 100 = 6 × 100 = 600 ords

Find the mode(s) of the data set shown.
2, 6, 8, 3, 4, 6, 2, 6, 8, 5, 6, 2, 7, 8, 4, 3, 2, 7, 3, 4
Answer:
the numbers 2 and 6 are both the modes.
Step-by-step explanation:
the mode is the number that appears the most. if there are two numbers that appear most often (and the same number of times) then the data has two modes.
the nubers 2 and 6 were repeated 4 times. causing them to be the modes of the data set :)
Answer:
6 and 2 is your answer
Step-by-step explanation:
1. You have the numbers 2, 6, 8, 3, 4, 6, 2, 6, 8, 5, 6, 2, 7, 8, 4, 3, 2, 7, 3, 4
2. Count how much each number occurs.
2 occurs 4 times
6 occurs 4 times
8 occurs 3 times
3 occurs 3 times
4 occurs 3 times
5 occurs once
And 7 occurs twice
3. See which number occured the most.
Since 6 and 2 occurred the most, 6 and 2 is the answer to this problem.----------------------------------------------

The face of a lamp shade is shaped like a trapezoid. The dimensions of the face are shown in the diagram.
Which equation can be used to find A, the area of the face of the lamp shade in square inches?
A = 1/2(6 + 10)yA = 12(6 + 10)y
A = 1/2(6) + (10)xA = 12(6) + (10)x
A = 1/2(6 + 10)xA = 12(6 + 10)x
A = 1/2(6) + (10)yA = 12(6) + (10)y
Answer:
A = (1/2)* (6+10) * x
Step-by-step explanation:
A = (1/2)* (6+10) * x
1. Mr. Hudson bought some shirts for the new members of his band. The cost for the number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. Write an equation to represent the scenario. Use x as your variable. 2 Mr. Hudson bought some shirts for the new members of his band. The cost for the number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts were purchased?
Answer:
6x + 4 - 1/100 = 77.5
Step-by-step explanation:
Inc shipping all shirts 77.49
Shirt individual cost = 12.25
We find the division first = 77.49-3.99 = 73.5 = 73 1/2
Then we divide 73.5 / 12.25 = 6
Then we have our equation
6x + 4 - 1/100 = 77.5
Put the following equation of a line into slope-intercept form, simplifying all fractions.
3x+2y=6
Answer: y=-3/2x+3
Step-by-step explanation:
First subtract 3x from both sides to start isolating the y.
Then you get 2y=-3x+6
Divide both sides by 2 to get y alone and you get
y=-3/2x+3
