9 (3−4) =9 ( 3t−4 )
Answers
Answer:
T = 1
Step-by-step explanation:
First we distribute to clean it up
\(9(3 - 4) = 9(3t - 4)\)
\(27 - 36 = 27t - 36\)
We add 36 to both sides.
\(27 = 27t\)
Last we divide by 27

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
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.

Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:

substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.
You buy a container of cat litter for $12.25 and a bag of cat food for x dollars. The total purchase is $19.08, which includes 6% sales tax. Write and solve an equation to find the cost of the cat food. PLEASE include an equation and explain how you did it, with details.
Answers
$19.08 x 0.06 = $1.1448 (amount of sales tax)
now subtract the sales tax from the total amount
$19.08 - $1.1448 = $17.9352
$17.9352-$12.25 (cat litter) = $5.69 (cat food)
Answer:
The cat food costs $5.75
Cost of litter, 12.25
Cost of cat food, X
Total including tax, 19.08
(12.25 + x)*1.06 = 19.08
Divide both sides by 1.06
(12.25 + x)*1.06/1.06 & 19.08/1.06
Simplify
12.25 + X = 18
Subtract both sides by 12.25
12.25 + x - 12.25 = 18 - 12.25
x = 5.75

Answers
Answer:
(16π - 32) in²
Step-by-step explanation:
In the picture attached, the circle is shown.
Area of one-quarter of circle = 1/4*Area of a circle = 1/4*π*radius² = 1/4*π*8² = 16π in²
Area of the triangle = 1/2*base*height = 1/2*8*8 = 32 in²
Shaded area = Area of one-quarter of circle - Area of the triangle = (16π - 32) in²

Which of the following is a solution to the equation 3 - 4y = 19?
Answers
Answer:
y= -4
Step-by-step explanation:
Equation: 3-4y= 19
Step 1: subtract 3 from both sides of the equation.
3-3-4y =19 -3
The 3's cancel out on the left side and on the right side you are left with 16.
Step 2: divide both sides by -4.
-4y÷-4= 16÷ -4
The -4's cancel out on the left side and on the right side you are left with -4.
y= -4
Answer:y=-4
Step-by-step explanation:
3-4y=19 Step One: subtract 3 on both sides to remove 3 on the left
-4y=16 Step Two: divide each side by negative 4 to leave y on it's own
y=-4 Your answer
