Answer:

If 2k - 4 = 12, 2k + 1= 11

Explanation:

2k - 4 = 12

2k=12+4

2k=16

k=8

plug k=8 into 2k + 1

2(8)+1= 11

-->2k+11 = 11

The probability for each event follows below:

P(A)= 0.23

P(E)= 0.24

P(F)= 0.28

P(N)= 0.12

P(O)= 0.07

P(S)= 0.06

<h3>Probability</h3>

Probability can be defined as the possibility that an event will occur. For an event, the probability can be found from the ratio between the number of favorable outcomes for the event and the total number of outcomes. Values of probability vary between 0 and 1.

A probability for an event is represented by P(A), P(B), etc. And exactly this that question asks for you.

1. Arrange the text of the question

North America=23 countries

South America= 12 countries

Europe= 47 countries

Asia= 44 countries

Africa =54 countries

Oceania= 14 countries

2. Find the total of countries

$N_{total}=23+12+47+44+54+14=194$

3. Find P(A)

A= the event that a country is in Asia= 44 countries. Therefore,

$P(A)=\frac{numberofcountries of Asia}{Total number of countries } \\ \\ P(A)=\frac{44}{194} =0.23\\ \\ P(A)=0.23$

4. Find P(E)

E= the event that a country is in Europe= 47 countries. Therefore,

$P(E)=\frac{numberofcountries of Europe}{Total number of countries } \\ \\ P(E)=\frac{47}{194} =0.24\\ \\ P(E)=0.24$

5. Find P(F)

F= the event that a country is in Africa= 54 countries. Therefore,

$P(F)=\frac{numberofcountries of Africa}{Total number of countries } \\ \\ P(F)=\frac{54}{194} =0.28\\ \\ P(F)=0.28$

6. Find P(N)

N= the event that a country is in North America= 23 countries. Therefore,

$P(N)=\frac{numberofcountries of North America}{Total number of countries } \\ \\ P(N)=\frac{23}{194} =0.12\\ \\ P(N)=0.12$

7. Find P(O)

O= the event that a country is in Oceania= 14 countries. Therefore,

$P(O)=\frac{numberofcountries of Oceania}{Total number of countries } \\ \\ P(O)=\frac{14}{194} =0.07\\ \\ P(O)=0.07$

8. Find P(S)

S= the event that a country is in South America= 12 countries. Therefore,

$P(S)=\frac{numberofcountries of South America}{Total number of countries } \\ \\ P(S)=\frac{12}{194} =0.06\\ \\ P(S)=0.06$

The diagram below depicts the international flow of funds in the 1920s.

Arada [10]

Number 1 represents the reparation payments from Germany to France and Britain.

<h3>What is the flow of funds?</h3>

The flow of funds implies the movement of money from one person or entity to another. In the case of the international flow of funds, this occurs as money moves from one country to another.

<h3>What does number 1 represent?</h3>

Considering number 1 occurs from Germany to France and Britain, it likely represents reparation payments. This is because by the end of the First World War in 1918 Germany had to pay a lot of money to the countries affected by its war actions, which included France and Britain.

Therefore, money flowed from Germany to France and Britain as shown in the diagram.

Note: This question is incomplete because the diagram and question are not provided. Here I attach the diagram and question.
