Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Answer: The first one is y=20x + 40;280
The second one is y=n+6
Step-by-step explanation:
The first one is y=20x+40 this is because when x is replaced with any number 20 will get multiplied by that number for example.
y=20x+40
If we assume that x is 4:
y=20(4)+40
y=80+40
y=120
our answer is 120.
I hope this helped.

Answer:
<
Step-by-step explanation:
the exponent will tell you how many places u need to move the decimal. 5.7 × 10 to the 2nd power = 570. u moved the decimal 2 places to the right.
If we interpret the statement correctly "5.7 x 5,700,000,000,000" means to multiply 5.7 with 5,700,000,000,000, which gives us the result of 32,490,000,000,000.
Therefore, we can write the statement as: 5.7 x 5,700,000,000,000 = 32,490,000,000,000.

Jack read 20 pages of a book in 60 minutes. How many pages can he read in 75 minutes at the same rate? Write a proportional equation. Please help me answer this equation!!
Answers
Answer:
25 pages
Step-by-step explanation:
Create a proportion:
\(\frac{pages}{minutes}\) = \(\frac{20}{60}\) = \(\frac{x}{75}\)
Cross multiply and solve for x, the number of pages in 75 minutes:
60x = 1500
x = 25
So, he can read 25 pages in 75 minutes at the same rate
He read 1 page in 3 minutes for 60 minutes 75 is 15 more than 60 so what time 3 would equal 15 It would be 5 so you would add 5 more pages to the 20 pages and you would get 25

which expression is equivalent to 18x-54?
A. 18(x-4)
B. 18(x-3)
C. 6(3x-18)
D. 3(9x-27)
Answers
Answer:
B. 18(x-3)
Step-by-step explanation:
- You have to find the GCMF of 18x and -54 first.
The GCMF is 18 so put it outside the ( )
18( )- Now ask yourself, 18 multiplied by what gives you 18x? the obvious answer is 18 multiplied by x gives you 18x, so now put the x inside the ( ).
18(x )- Again ask yourself, 18 multiplied by what gives you -54, the answer is -3 so now put -3 inside the ( ) too.
18(x-3)Remember its negative 3 not positive, so while writing it in the ( ), write -3 not just 3.The expression which is equivalent to 18x - 54 is 18(x - 3) so, option B is correct.
What is GCF?The biggest positive number that divides each of the two or more non-zero integers is known as the greatest common divisor.
Given:
18x - 54
Calculate the GCF of 18 and 54 as shown below,
18 = 2 × 3 × 3
54 = 2 × 3 × 3 × 3
GCF = 2 × 3 × 3
GCF = 18
Take the GCF common as shown below,
18x - 54 = 18(x - 3)
Thus, the equivalent expression is 18(x - 3).
