Answer:
H. is the correct answer.
Step-by-step explanation:
You find range by subtracting the lowest amount from your data by the highest amount. The highest number in Ms. Gambino's class is 12, and the lowest is 5.
\(12-5=7\) This is the range of Ms. Gambino's class
The highest number in Mr. Joe's class is 10 and the lowest is 5
\(10-5=5\\\) This is the range of Mr. Joe's class.
Therefore, the range in Mr. Joe's class is less than the range of data in Ms. Gambino's class.

Step-by-step explanation:
There are 4 numbers in total (5,10,15,z)
The mean is when you get the total of all the numbers and divide by how many there are
If you do the inverse then that means that 20 x 4 = total of all 4 numbers
80 = 15 + 10 + 5 + z
80 = 30 + z
z = 80 - 30

Amanda can jog 18 miles in 5 hours.
At this rate, how many miles can Amanda jog in 4 hours?
Answers
Answer:
14.4
Step-by-step explanation:
Divide 18 miles by 5 hours to tell us how many miles she can do in 1 hour.
Multiply the answer by 4 to tell us how many miles in 4 hours.
(18/5) * 4 = 14.4 Miles
Answer:
14.4 miles
Step-by-step explanation:
To answer this question you first need to find out what Amanda can jog in 1 hour. I can do this by dividing by 5, since the question tells me that she jogs 18 miles in 5 hours. So, I do 18 divided by 5, which gives me 3.6. I now know that in one hour, she can jog 3.6 miles.
The next step is to multiply by 4, because I want to know what she can do in 4 hours. So, I do 3.6 multiplied by 4, which gives me 14.4. I now know she can jog 14.4 miles in 4 hours, which is my final answer,

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
6
Step-by-step explanation:
18-2.5+7 there s your helllppppppppppp
New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet
Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.
Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:
Area = (1/2) x base x height
Area = (1/2) x 18 x 7 = 63 square feet
To find the area of the new deck, we can use the same formula and plug in the new dimensions:
Area = (1/2) x 7.2 x 2.8 = 11.88 square feet
Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.
Part C: The ratio of the areas is:
63/11.88 = 5.303
The scale factor is:
2/5 = 0.4
To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:
5.303/0.4 = 13.2575
Therefore, the ratio of the areas is 13.2575 times the scale factor.
Shilo is sharing jellybeans. The jar of jellybeans has a ratio of 32:56. If shilo keeps the ratio the same and gives his friend 7 pink jellybeans, how many green jellybeans would he also share
Answers
Answer:
12 green jellybeans
Step-by-step explanation:
To keep the ratio of 32:56, we need to divide both sides by the greatest common factor.
32 and 56 have a GCF of 8, so we can simplify the ratio to 4:7.
This means for every 4 pink jellybeans, there are 7 green jellybeans.
If Shilo gives 7 pink jellybeans to his friend, he needs to give them 7/4 * 7 = 12.25 green jellybeans. Since he can't give a fractional jellybean, he would need to give his friend 12 green jellybeans

Answer the following linear equations: x3+y3+z3=k
2x – y = 6, x – y = 2
and ax + by = a-b, bx – ay = a+b
TYVM!! :)
Answers
Answer:
Linear Equation 1 — 3xyz
Linear Equation 2 — x = 4 and y = 2
Linear Equation 3 — x = 1 and y = (-1)
Step-by-step explanation:
(Linear Equation 1)
The equation x3+y3+z3=k is known as the sum of cubes problem. While seemingly straightforward, the equation becomes exponentially difficult to solve when framed as a "Diophantine equation" -- a problem that stipulates that, for any value of k, the values for x, y, and z must each be whole numbers.
The required result must be 3xyz.
(Linear Equation 2)
2x − y = 6 ....(1)
x − y = 2 ....(2)
Equation(2)−Equation(1) we get
x − y − 2x + by = 2 − 6
(−x) = (−4)
x = 4
Substitute x = 4 in (1) we get
2x − y = 6
2*4 − y = 6
8 − y = 6
(−y) = 6 − 8
y=2
(Linear Equation 3)
ax + by = a − b .......... (1)
bx − ay = a + b .......... (2)
Multiply equation (1) with a and equation (2) with b ,
a²x + aby = a² − ab ..........(3)
b²x − aby = ab + b² ......... (4)
Adding (3) and (4), we get,
(a² + b²)x = a² + b²
x = 1
Now, from (1),
ax + by = a − b
a + by = a − b
by = (−b)
y = (−1)

Answer:
1. (A) Greece has the longest coastline in Europe and is the southernmost country in Europe. The mainland has rugged mountains, forests, and lakes, but the country is well known for the thousands of islands dotting the blue Aegean Sea to the east, the Mediterranean Sea to the south, and the Ionian Sea to the west.
1. (B) Rome was built on a defensible hill that dominated the last downstream, high-banked river crossing where traverse of the Tiber was facilitated by a midstream island. This hill, Palatine Hill, was one of a group of hills, traditionally counted as seven, around which the ancient city grew.
1. (C) The fertile soil of the Po and Tiber River Valleys allowed Romans to grow a diverse selection of crops, such as olives and grains. Greece's steep mountains and surrounding seas forced Greeks to settle in isolated communities. Travel by land was hard, and sea voyages were hazardous. Most ancient Greeks farmed, but good land and water were scarce. They grew grapes and olives and raised sheep, goats, pigs, and chickens.
2. (A) Monotheism:
So mono means like one, so monotheism means that you only believe in one god. (The three religions of Judaism, Christianity, and Islam readily fit the definition of monotheism)
Polytheism:
So poly means more than one, so polytheism is the opposite of monotheism (more than one god) (for example, Hinduism, Shintoism, Thelema, Wicca, druidism, Taoism, Asatru, and Candomble).
2. (B) Jewish people believe there's only one God who has established a covenant—or special agreement—with them. Their God communicates to believers through prophets and rewards good deeds while also punishing evil. Most Jews (with the exception of a few groups) believe that their Messiah hasn't yet come—but will one day.
2. (C) Christians believe there's only one God, and he created the heavens and the earth. This divine Godhead consists of three parts: the Father (God himself), the Son (Jesus Christ), and the Holy Spirit.
2. (D) So I was not sure about the Greek, so I only did the Roman part, hope that's alright. As different cultures settled in what would later become Italy, each brought its own gods and forms of worship. This made the religion of ancient Rome polytheistic, in that they worshipped many gods. They also worshipped spirits. Rivers, trees, fields, and buildings each had their own spirit or numen. (I think)
3. (A) The Greeks made important contributions to philosophy, mathematics, astronomy, and medicine. Literature and theatre was important aspect of Greek culture and influenced modern drama. The Greeks were known for their sophisticated sculpture and architecture.
3. (B) The legacy of Ancient Rome is still felt today in Western culture in areas such as government, law, language, architecture, engineering, and religion.
(Not too sure about this one) Roman models of colonialism and of warfare also became influential.
It was due to their exceptional concrete that they were able to produce their sturdy aqueducts and bridges as well as other structures.
3. (C) The Greeks made important contributions to philosophy, mathematics, astronomy, and medicine.
3. (D) A people known for their military, political, and social institutions, the ancient Romans conquered vast amounts of land in Europe and northern Africa, built roads and aqueducts, and spread Latin, their language, far and wide.
3. (E) Though it has been thousands of years since the Roman Empire flourished, we can still see evidence of it in our art, architecture, technology, literature, language, and law.
3. (F) The Greeks pretty much invented modern mathematics, sculpture, philosophy, science, and even medicine.

Tom is saving money to buy a game. So far he has saved $18, which is two-thirds of the total cost of the game. How much does the game cost?
Answers
To determine the total cost of the game, we can set up an equation based on the given information.
Let's assume the total cost of the game is represented by the variable "x."
According to the problem, Tom has saved $18, which is two-thirds of the total cost. We can express this as the equation:
(2/3) * x = $18
To solve for x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:
(3/2) * (2/3) * x = (3/2) * $18
x = $27
Therefore, the game costs $27.

Answers
To determine the scale factor used to dilate polygon ABCD to A′B′C′D′, we can compare the corresponding side lengths.
The distance between A(1, 1) and B(3, 1) is 2 units, and the distance between A′(3, 3) and B′(9, 3) is 6 units, so the horizontal side has been scaled by a factor of 6/2 = 3.
Similarly, the distance between A(1, 1) and D(1, 2) is 1 unit, and the distance between A′(3, 3) and D′(3, 6) is 3 units, so the vertical side has been scaled by a factor of 3/1 = 3.
Since both scaling factors are equal to 3, the overall scale factor used to dilate the polygon is 3. Answer: 3.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

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

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:
1.) 5x-4y=20
y=5/4x-5
5x/4-5=0
x=4
2.) 3x+3y=15
y=-x+5
x+5=0
-x=-5
=x=5
3.) y=3/4x-2
3/4x-2=0
x=0
