Solve for x: 2^(x+4) = 4^(x-2) A. 0 B. 1 C. 4 D. 6 E. 8

1 answer:

8 0

Because this gives you multiple choice, you can just plug in all the numbers given and try them.
A: Since this says that x equals 0, you would get 16 isn't equal to 1
B: Since this says that x equals 1, you would get 32 isn't equal to .25
C: Since this says that x equals 4, you would get 256 isn't equal to 16
D: Since this says that x equals 6, you would get 1024 isn't equal to 256
E: Since this says that x equals 8, you would get 4096 IS equal to 4096

So E is CORRECT!!

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,

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

6-2 skills practice inverse functions and relations

xenn [34]

There are a lot of inverse functions and relations. An example of this 6-2 skills math is find the inverse of the following relations {(3, 1), (4, -3), (8, -3)}.

<h3>What is inverse functions?</h3>

The term inverse function connote a type of function (f) that is also a function that often undoes a form of operation of (f).

The inverse of the relations. {(3, 1), (4, -3), (8, -3)} is therefore

{(1, 3), (-3, 4), (-3, 8)} .

It is {(1, 3), (-3, 4), (-3, 8)} because one just have to change the arrangement.
