Part A: Calculate the measures of center. Show all work. (2 points)
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)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

A bakery uses 70% of its milk in one week. They now have 36 quarts of milk left. How many quarts did the bakery use during the week? The bakery used quarts of milk. Part C There are 4 quarts in a gallon. How many gallons of milk did the bakery use during the week?
Part 1)
Data:
70% milk used in a week
36 quarts of milk left
How many quarts used during the week?
Solution:
(Here we are supposed to find the milk USED, which is 70%, now we know that milk which is left is 36 quarts and it is obvious that the percentage of the milk left is 30% because 100% - 70% = 30%. )
You'll get your answer through the following equation:
(70% × 36 quarts) ÷ 30% = 84 quarts
Answer:
Therefore, the bakery used 84 quarts of milk during the week.
Part 2)
Data:
1 gallon = 4 quarts
Solution:
(Here, we're simply asked to convert the quarts of milk used during the week into gallons.)
If 1 gallon is 4 quarts, then:
84 quarts ÷ 4 = 21 gallons
Answer:
Therefore, the bakery used 21 gallons of milk during the week.
Answer: they used 84 quarts or 21 gallons

Triangle NGM is reflected across the x-axis, and is dilated by a factor of
\(2 \frac{1}{2} \)
what are the coordinates of vertices N'G'M'
The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).
From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).
Scale factor = \(2\frac{1}{2}\)
= 2.5
The reflection of point (x, y) across the x-axis is (x, -y).
Here, N(-4, 6)→(-4, -6)
M(-6, 2)→(-6, -2)
G(-2, 4)→(-2, -4)
Now, with scale factor 2.5, we get
(-4, -6)→2.5(-4, -6)→N'(-10, -15)
(-6, -2)→2.5(-6, -2)→M'(-15, -5)
(-2, -4)→2.5(-2, -4)→G'(-5, -10)
Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

The lengths of the sides of a small cube are 1 over 4 foot each.
Part A: How many small cubes can be packed in the rectangular prism? Show your work. (5 points)
Part B: Use the answer obtained in part A to find the volume of the rectangular prism in terms of the small cube and a unit cube. (10 points)
Answer: 84 cubes
Step-by-step explanation: Given, The dimension of the rectangular prism are, 1 1/3 ft. * 1 * 2 1/3 = 4/3 * 7/3 = 28/9 cube ft.
Now, the volume of a cube = side³, if side = 1/3 ft., Then the volume of each cube, V = (1/3)³ = 1/27 cube ft.
Hence, the number of cubes that can be packet in the prism = V/V1 = 28/9 / 1/27 = 27*28/9 = 3 * 28 = 84
A) The number of small cubes which can be packed in the rectangular prism are 180.
B) The volume of the rectangular prism in terms of the small cube and a unit cube will be 180 units³
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
Length = 2 1/4 feet
Width = 1 feet
Height = 1 1/4 feet
And, The lengths of the sides of a small cube are 1 /4 foot each.
Now,
Since, The volume of rectangular prism = Length x width x height
Substitute all the values, we get;
⇒ The volume of rectangular prism = 2 1/4 × 1 × 1 1/4
= 9/4 × 1 × 5/4
= 45/16 ft³
= 2.81 ft³
And, The Volume of one cube = Side³
Here, The length of side of cube = 1/4 feet = 0.25 feet
Hence, The Volume of one cube = Side³
The Volume of one cube = 0.25³
The Volume of one cube = 0.015625 ft³
So, The number of small cubes that can be packed in the rectangular prism = Volume of rectangular prism / Volume of cube
= 2.81 /0.015625
= 180
B) The length, the width and the height of the rectangular prism in term of units cubes is:
Length = 2 1/4 feet / 0.25 feet = 2.25 / 0.25 = 9 units
Width = 1 feet / 0.25 feet = 4 units
Height = 1 1/4 feet / 0.25 feet = 1.25 / 0.25 = 5 units
So, The volume of the rectangular prism in terms of the small cube and a unit cube is,
Volume = 9 x 4 x 5
= 180 units³

Answer:
x = 7.5, y = 8.5-----------------------------------
The two angles with the variable x form a linear pair and therefore:
16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5Angles 16x - 18 and 12y are congruent as vertical angles:
16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5Answer:
x = 7.5
y = 8.5
Step-by-step explanation:
Linear Pair
Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).
To find x, equate the sum of the two angles with the variable x to 180° and solve:
⇒ (16x - 18)° + (10x + 3)° = 180°
⇒ 16x - 18 + 10x + 3 = 180
⇒ 26x - 15 = 180
⇒ 26x = 195
⇒ x = 7.5
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Therefore:
⇒ (16x - 18)° = 12y°
Substitute the found value of x into the equation and solve for y:
⇒ 16x - 18 = 12y
⇒ 16(7.5) - 18 = 12y
⇒ 120 - 18 = 12y
⇒ 102 = 12y
⇒ y = 8.5
