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!

1)
x + 2x
= 1x + 2x
= (1 + 2)x
= 3x
2)
2x - x
= 2x - 1x
= (2 - 1)x
= 1x
= x
3)
4x + 2x
= (4 + 2)x
= 6x
4)6x - 3x
= (6 - 3)x
= 3x
5)5x + x
= 5x + 1x
= (5 + 1)x
= 6x

Water flows back and forth between a small and large tank. When water is moving into a tank the flow rate is positive, and when water is moving from a tank the flow rate is negative. The large tank begins with 300 gallons of water, and the small tank begins with 200 gallons of water. After a period of 5 minutes, the large tank has the same amount of water as the small tank. Which statement describes the flow rate?

Please help me with the work
Answer:
1. you answered correctly :)
2. how many 1/4's go into 12? in other words multiply 12 and 4 to get 48/4
3. Draw a diagram of 1/5ths until it equals 15 (you'll need a total of 75 boxes)
4. the problem is 18z=72 so you need to divide 72 and 18. 72/18=4. therefore z equals 4.
5. make up a division problem that has the answer of 8. for example 24/y=3. y will equal 8. and then use a tape diagram for that.
6. make up a multiplication problem that has an answer of 8. for example 3y=24. y will equal 8. and then use a tape diagram for that.
7. Meghan is correct. when you have y divided by two you need to do the opposite and multiply both sides by two. Meredith was incorrect because she switched the division and multiplication signs completely which is not what you are supposed to do.
Step-by-step explanation:
I hope this helped :) (the only thing you could write down word for word is #7. for 1-6 just read what i have to say and follow the directions and it should help) have a great day!!!!
I will solve these equations algebraically.
Here you are:
1. 30= 5w
Divide each side by 5.
30÷5= 5w÷5
6 = w
∴ w= 6
To check,
30=5w
Substitute w for 6
30= 5 x (6)
30= 30
LS= RS
(You were correct, great job!)
2.
12 = x÷4
Multiply each side by 4.
12 x 4 = x/4 x 4 ↔ 4 and 4 cancel out.
48= x
∴ x=48
Checking:
12= 48÷4
12= 12
LS=RS
3.
y÷5=15
Multiply each side by 5.
y÷5 x 5= 15 x5
y =75
∴y=75
Checking:
Substitute y for 75.
y÷5=15
75÷5=15
15=15
LS=RS
4.
18x=72
Divide each side by 18.
18x ÷ 18= 72÷18
x = 4
∴x= 4
Checking
18x=72
18(4)=72
72=72
LS=RS
I hope that these solutions helped you. I am sure that using the solutions, you can figure out the other questions on your own.
