Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?
Answers
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)
Hence, we conclude that exists 211680 ways.

https://brainly.com/question/30958797
For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.
Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.
For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.
To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.
Therefore, there are 211,680 ways to select a delegate and an alternate from each department.

Answers
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.

the table shows the results of rolling a number cube labeled 1 through 6 30 times
based on the results, if the cube roles 200 times, how many times is it expected to land on 1
Answers
Answer:
40 times
Step-by-step explanation:
To figure this out, divide 6 by 30, then multiply by 200
(6/30)200 = 40
This also works: (200/30)6 = 40
We divide 6 by 30 because we landed on the 1 side 6 times out of 30. We then multiply 6/30 by 200 because it is out of 200 this time, so we will multiply 6 by 200 then divide by 30. 200(6) = 1200. 1200/30 = 40.

Consider the standard form of an exponential function:
\(y=a(b)^x\)
How does changing the base number (inside the parentheses) change your graph?
Answers
Answer:
Step-by-step explanation:
Challenge 1
We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.
If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.
Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).
Remember that b cannot be negative.
===========================================
Challenge 2
In the general template provided, enter x = 0.
y = a(b)^x
y = a(b)^0
y = a(1) (1)
y = a
When x = 0 is plugged in, the result is y = a.
The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.

A triangular prism is attached to a rectangular prism as shown below.
If w = 8 inches, x = 5 inches, y = 20 inches, and z = 11.3 inches, what is the total surface area of the EXTERIOR FACES of the figure?
(Answer choices in picture!!) (I WILL GIVE BRAINLIEST)
Answers
Surface area of the triangular prism:
The triangular prism has two triangular faces and three rectangular faces.
The triangular faces have base (x) of 5 inches and height (y) of 20 inches. The surface area of each triangular face is (1/2) * base * height = (1/2) * 5 * 20 = 50 square inches.
The rectangular faces have dimensions (w, y, and z) of 8 inches, 20 inches, and 11.3 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the three rectangular faces, we get: 2 * (w * y) + 2 * (w * z) + 2 * (y * z) = 2 * (8 * 20) + 2 * (8 * 11.3) + 2 * (20 * 11.3) = 320 + 180.8 + 452 = 952.8 square inches.
Surface area of the rectangular prism:
The rectangular prism has six rectangular faces.
The dimensions of the rectangular prism are (w, x, and y) of 8 inches, 5 inches, and 20 inches, respectively. The surface area of each rectangular face is length * width. Adding the surface areas of the six rectangular faces, we get: 2 * (w * x) + 2 * (w * y) + 2 * (x * y) = 2 * (8 * 5) + 2 * (8 * 20) + 2 * (5 * 20) = 80 + 320 + 200 = 600 square inches.
Total surface area of the exterior faces:
To find the total surface area of the exterior faces, we add the surface areas of the triangular prism and the rectangular prism: 50 + 952.8 + 600 = 1,602.8 square inches.
Therefore, the total surface area of the exterior faces of the figure is approximately 1,602.8 square inches. However, none of the given answer choices match this value. Please recheck the given dimensions or options provided.
Find the surface area of a top open cylinder
12 in radius
2 in height
Answers
The surface area of the top open cylinder is 6810.149 sq.cm.
A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.
Surface area of a cylinder = Base area + Lateral area
Base area of a cylinder = 2 × π × r²
Lateral area of a cylinder = (2 × π × r) × h
Therefore, here base area of a cylinder = 2× π × 12²
= 5837.27 sq.cm.
And, lateral area of a cylinder = (2 × π × 12) × 2
= 972.8784 sq.cm.
Therefore, total surface area of a cylinder = 5837.27 + 972.8784
= 6810.149 sq.cm.

Solve for u. -9–4u=-u
Answers
Answer:
u = -3
Step-by-step explanation:
-9 - 4u = -u
+4 = +4
Add 4u to both sides.
-9 = 3u
Divide both sides by 3
-9/3 = 3/3
-3 = u
Answer: The variable u is equal to -3 for this equation.
Step-by-step explanation:
To solve this variable equation, you will need to follow these steps:
Rewrite the equation, moving 9 to the other side, adding it on both sides, and simplify
-4u = -u + 9
After that, move u to the other side of the equation, also adding it on both sides and simplify
-3u = 9
Then divide both sides by -3, simplify it one last time and you will get your answer!
-3
Therefore, the answer to this equation would be equal to negative three or -3. Hope this helps!
