The following dot plot represents student scores on both the Unit 1 and Unit 2 math tests. Scores are in whole number increments.
Part 1: Looking at the data plots, which test do you think the students scored better on? Do you think one of the tests has more variation than the other or is the variation about the same for both tests? Use complete sentences in your answer and explain your reasoning.
Part 2: Calculate the mean (rounded to the nearest whole number) and mean absolute deviation for the Unit 1 test.
Part 3: Do your results from part B prove or disprove your hypotheses from part A? Use complete sentences in your answer and explain your reasoning.
Answers
Part 1: It is most definitely Unit 2. I know this because there are more dots on the left side of Unit 2 than there are on Unit 1.
Unit 2 has 24 dots in total while Unit 1 has 25.
Part 2: Mean = 13 (13.44)
Mean Absolute Deviation = 3 (2.848)
Part 3: The results from part B prove my hypotheses from part A. How? The mean and MAD of Unit 1 are smaller than Unit 2's measurements, which I will not include because the question says only Unit 1 test measurements.

Which ratio is greater, 4:5 or 3:4?
Answers
explanation-
Express the given ratios as fraction
4 : 5 = 4/5 and 2 : 3 =2/3
Now find the L.C.M (least common multiple) of 5 and 3
The L.C.M (least common multiple) of 5 and 3 is 15.
Making the denominator of each fraction equal to 15, we have
4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15
Clearly, 12 > 10
Now, 12/15 > 10/15
Therefore, 4 : 5 > 2 : 3.

4:5

6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is

The answer comes out to 11.125 however in mixed number form it’s 11 1/8
Answer:
11 and 1/8
Step-by-step explanation:
We can do this in the format of PEMDAS
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
10 + (2 × 3[tex])^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]
Let's do the parenthesis first
10 + [tex]6^{2}[/tex] ÷ 4 × [tex]\frac{1}{2} ^{3}[/tex]
Now we can do the fraction with the exponent second
10 + [tex]6^{2}[/tex] ÷ 4 × [tex]\frac{1}{8}[/tex]
Now we can do the other exponent
10 + 36 ÷ 4 × [tex]\frac{1}{8}[/tex]
Now we can divide the 36 and 4
10 + 9 × [tex]\frac{1}{8}[/tex]
Now we can multiply the 9 and [tex]\frac{1}{8}[/tex]
10 + [tex]\frac{9}{8}[/tex]
And we can convert the improper fraction to a mixed number
10 + 1 1/8
And now we can add them up, the 2 whole numbers and the fraction stays the same
11 1/8

Explain how you would find a precent increase or a percent decrease.
don't put I don't know or I don't know or ill report you
Answers
Answer:
You can find a percent increase because the percentage would go up. Like 30% if it increased it would go up too 50%. Which increased by 80%. And you can also add and subtract to make sure your answer is correct.
To find a deacrease it means that the percentage would go down. Like 80% to 60% is a decrease because it went down by 20%.

y= 12x-16
Step-by-step explanation:
Given that you have a slope of 12 and a point of (3, 20), you are most obligated to using the Slope-Intercept form, or y=mx+b.
What this allows you to find is the y-intercept if your line has one. You take your point, (3,20), and you insert the values at the appropriate places. You should now have 20=12(3)+b. You will then solve for b by multiplying 12 and 3 to get 36 and subtract that from both sides of the equal sign. You should have 20-36=b. 20-36 is -16, which is your y-intercept.
