The data provided below describe an ice-cream store’s daily production possibilities for milkshakes and sundaes.
-----
Milkshakes 0 20 40 60 80 100 120
Sundaes 210 200 180 150 110 60 0
-----
(a) Draw a correctly labeled graph of the store’s production possibilities curve (PPC) with milkshakes on the horizontal axis and sundaes on the vertical axis and label the endpoints using the numbers provided above.

(b) Is the opportunity cost of producing milkshakes increasing, decreasing, or constant? Explain using numbers in the table.

(c) The store is currently producing 80 milkshakes and 110 sundaes. Calculate the opportunity cost of increasing milkshake production from 80 to 100 milkshakes. Show your work.

(d) Would it be efficient for the store to produce 80 milkshakes and 150 sundaes? Explain using numbers in the table.

(e) Suppose the ice-cream store purchases a new machine that increases the output of milkshakes and sundaes. Show the effect of the change on the store’s PPC on your graph in part (a).

Answers

(a) Please see the attached graph

(b) The opportunity cost is increasing

(c) The opportunity cost is the -77.5 units of sundae not produced

(d) The function is note defined at c = (80, 150)

(e) The slope of the graph will change less rapidly, and the opportunity cost of producing milkshake will increase

Reason:

(a) The given data in a tabular form is presented here;

[tex]\begin{array}{|c|cc|}\mathbf{Milkshakes} &&\mathbf{Sundaes}\\0&&210\\20&&200\\40&&180\\60&&150\\80&&110\\100&&60\\120&&0\end{array}[/tex]

Please find attached the required drawing of the Production Possibility Curve (PPC) created with MS Excel

The endpoints are;

A(0, 210): Sundaes are the goods mainly produced while no milkshakes is produced

B(120, 0): No sundaes is being produced while milkshakes are the goods mainly in production

(b) The opportunity cost producing milkshakes is the amount of sundaes forgone

[tex]\begin{array}{|c|c|c|}\mathbf{Milkshakes} &\mathbf{Sundaes}& \mathbf{\dfrac{\Delta Sundaes}{\Delta Milkshakes} }\\0&210&-0.5\\20&200&-1\\40&180&-1.5\\60&150&-2\\80&110&-2.5\\100&60&-3\\120&0&\end{array}[/tex]

[tex]\mathbf{\dfrac{\Delta Sundaes}{\Delta Milkshakes} } = Rate \ of \ Change \ of \ Sundaes \ to \ Milkshakes \\[/tex]

From the rate of change column of the above table, as the quantity of milkshake produced is increasing, the quantity of sundaes produced decreases more as shown by the progressively increasingly negative rate of change of sundae to milkshake produced

Therefore, the opportunity cost of producing milkshake, which is the quantity of sundae produced, is increasing

(c) The number of sundae produced when producing 80 milkshakes is 110

When the production of milkshakes is increased from 80 to 100, the expected quantity of sundae produced is (110/80) × 100/1 = 137.5

Therefore, 137.5 units of sundae is expected to be produced from 100 units of milkshakes

The actual quantity of sundae produced when the quantity of milkshake produced is 100 is 60

Therefore, the opportunity cost is the extra 20 milkshakes, is the deficit (137.5 - 60 = 77.5

The opportunity cost = -77.5 units of sundae not produced

(d) When the quantity of milkshakes produced = 80, the maximum quantity of sundae that can be produced is 100

Therefore, the condition (80, 150) is not feasible

(e) Given that the quantity of milkshake produced by the new machine is increasing, the rate of change of the sundae to milkshake will decrease, but the the opportunity cost of producing milkshake will continue to increase

Media are connected to networks that make information easier to access and pass on. D. Networks feed media only important information that can be communicated to many people.

Answers

Answer:

The answer should infact be C using the process of elimination.

Explanation:

A would be false because networks send data to specific kinds of media like games, server hosts, ect to send them data and cookies and information that tells them about whos using the media, and whats going on. In a game sense it would connect the player to the in game server, which sends data from the network to the game. B is incorrect. Networks send data over wireless, and wired connections, but media does not. C is correct due to process of elimination (i'm not super smart but this is how i'd come to the conclusion on this question.) D. Networks send all types of information, not just important.

Answers

Answer:

Chaos would happen and one branch will always have more power over the other branch. If they are all together, what is right and what is wrong. Is too much power being used? What laws to make? What actions to make? IF for not these questions perhaps, there would have been only one branch of the government. The executive branch has immense power and can be overpowered as well, but, that does not mean it can do any foolishness it wants. That is why the judicial branch exists and it has specific power, great power, to overrule anything if it is deemed wrong or unconsitituional. The president doesn't necessarily create law either. He writes them into law and may have some power or influence to add in laws he likes or wants. The legislative branch looks over the laws and creates them. The president merely looks over it and signs it. The judical branch also has the power to overrule laws that are unjust or unconstitutional. Together, these three branches make up the government. Without each other, or to be said, as single, the nation would be no more.

The table shows the types of information collected by a store regarding customer purchases. Which of the following data could be used in a geographical information system (GIS) to increase sales?

Answers

A geographical information system (GIS) is an information system that is used to manage data. They are also used to create and organize data. The total transaction amount can be used by the GIS to increase sales

From the attached table, we have the following data:

Zip code areaNumber of customersNumber of transactionsTotal transaction amountAmount per transaction

The usage of each data is as follows:

The zip code can be used to determine the region of the customers.

The number of customers and the number of transactions can be used to determine the rate of transactions per customer

We observe that, the total transaction amount is the product of the number of transactions and the amount per transaction.

This means that the total transaction amount is a summary of two other columns which deals directly with sales.

Information about total transaction amount can then be used independently to determine, predict and increase the sales of the store.

I see no contradiction in the fact that Americans share similar ideals but are on opposite sides of party politics.

There are many ways of achieving a desired goal. While it is true that Americans share common ideals like justice, honesty, a government for the people and by the people, hardwork, etc., the truth remains that realizing these ideals is not a straight path.

Different routes might be required to attain these ideals and that is why Americans could either belong to the Republican party or the Democratic party.

So long as these parties are working for the good of the common man, then there is no contradiction in citizens belonging to different parties.

What are the colors of the rainbow and what they stand for??

Answers

Every rainbow has seven colors beginning with red and ending with violet or purple. To remember the order of these colors, people use the acronym ROY G. BIV or VIBGYOR which stands for Red Orange Yellow Green Blue Indigo and Violet.
Red– This is the first color of the rainbow from top. Red signifies passion, vitality, enthusiasm and security. It is the light with the longest wavelength.
Orange– This light or color is a combination of yellow and red. It is a dynamic color representing creativity, practicality, playfulness as well as equilibrium or control.
Yellow– This is the color of the sunshine itself. It represents clarity of thought, wisdom, orderliness and energy.
Green– This is the middle color of the rainbow and denotes fertility, growth, balance, health and wealth.
Blue– This the fifth color of the rainbow which makes us think of the Unknown. The sky and the wide oceans are in this color and hence it has been associated with Spirituality and Divinity.
Indigo– It is believed that where Blue is calming, Indigo is sedating. Indigo is mystical as it bridges the Gap between Finite and Infinite. Indigo colored gem stones are often used for spiritual attainment, psychic abilities, self awareness and enhancement of Intuition.
Violet– The last color of the rainbow is a mix of red and blue. It is considered the highest element of spirituality. It can ignite one’s imagination and be an inspiration to artists. Dark tones of violet are associated with sorrow. Deeper shades of violet or purple denote high spiritual mastery.
