The value of the conditional Probability is P(A|B) is 1/3.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The main distinction between a probability and a conditional probability is that a probability is the likelihood of an event, such as A, occurring, whereas a conditional probability assumes that another event, such as B, has already happened in order to define the probability of an event, such as in the conditional probability of A given B.

Conditional probability is the likelihood that any event A will occur in the presence of another event B that is related to A. P(A|B) illustrates it.

By, Conditional Probability :

P (A∩B) =P (A∩B') - P(B)= 4/9 - 1/3 = 1/9

P(A|B) = P (A∩B)/ P(B)

           = (1/9)/(1/3) =  1/3

What is Ratio ?

In mathematics, the term "ratio" is used to compare two or more numbers. It is used to show how big or little an amount is in relation to another. Two quantities are compared using division for calculating a ratio.

Given, It takes 29 pounds of seed to completely plant a 5-acre field.

So, Acres per pound of seed = 5 Acres ÷ 29 pounds of seed

The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.

For a probability distribution to be legitimate, the probabilities of all the possible values of a random variable need to add up to 1. So, in this case, the sum of all the probabilities must be equal to 1.

For the given values, we can assign the probability of 0.2 to the values 0 and 3, 0.3 to the value 4 and 0.1 to the value 6, so that the sum of all the probabilities is 1.

Therefore, the legitimate probability distribution for the given discrete random variable X is as follows:

| Value (x) | P(X=x) |

|---|---|

| 0 | 0.2 |

| 3 | 0.2 |

| 4 | 0.3 |

| 5 | 0.2 |

| 6 | 0.1 |

Y = 2(x-2)²+2 is the equation used to model the bird's vertex form journey.

A vertex is a point on a polygon where two rays or line segments meet, the sides, or the edges of the object come together. Vertex is the plural form of vertices. For instance, the points A, B, C, D, and E in the aforementioned figures are vertices.

Formula for the general vertex form: f(x) = a(x − h) ² + k

where the vertex is (h,k).

This equation can be used to represent a bird's flight path:

y = 2x² - 8x+10

Vertex form equation conversion

Filling in the square:

y = 2(x² - 4x+5)

y=2

(x²-4x+5+ (2)2- (2)2)

y=2(x²-4x+5+ (2)²-4) y=2((x-2)2-4+5)

A percentage is mathematics is a figure or number that is stated as a proportion of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. However, the symbol "%" used to denote it is frequently used. The percentage amount is flat; there are no dimensions. Given that their numerator is 100, percentages are basically fractions.

Here,

According to the clauses 1/10, n/30, the buyer would receive a 1% reduction if the discount was applied within 10 days.

The consumer would be required to pay the whole amount in 30 days if the payment was not completed within this time frame.

Considering this and the fact that Nieman invoiced $2,400 for the returned goods, you must deduct this sum from their original purchase:

=> $12,200-$2,400= $7,800

Then, you must figure out the discount at 1% of $7,800 and deduct it from $7,800:

=> $7,800*1%= $78

=> $7,800-$78= $7,722

The prove that the given expression is divisible by 43 is explained below.

A number is said to be divisible by a given number when it leaves no remainder after the division. Example; show that 7^7 is divisible by 49.

7^7 = 823543

So that;

823543/ 49 = 16807

To prove that the expression is divisible by 43, we have;

7^8 = 5764801

7^7 = 823543

7^6 = 117649

Then,

7^8 - 7^7 + 7^6 = 5764801 - 823543 + 117649

                         = 4941258 + 117649

The equation represents the relation between s and t is s = 9t

This question is an example of Direct Variation, which is a type of proportional relationship between two variables. In direct variation when one variable increases, so does the other, and when one variable decreases, so does the other.

This relationship can be expressed mathematically by the equation

y = k x

where k is the constant of variation. In the given problems is the dependent variable, and t is the independent variable.

Since we know that when t = 4, s = 9, we can substitute these values into the equation and solve for k.

Answer:

2^1 = 2 -> last digit is 2

2^2 = 4 -> last digit is 4

2^3 = 8 -> last digit is 8

2^4 = 16 -> last digit is 6

2^5 = 32 -> last digit is 2

2^6 = 64 -> last digit is 4

2^7 = 128 -> last digit is 8

We can observe that the last digit follows a pattern of 2,4,8,6,2,4,8 and repeat.

Therefore, 2 to the power of 47 will have the same last digit as 2 to the power of (47 modulo 4) + 3

In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.

here, we have,

f(x)=logx

How to determine the equation of g(x)?

From the graph, the given parameters are:

f(x) = log(x)

From the graph, we can see that:

The graph of f(x) is translated left by 1 unit

The graph of f(x) is translated up by 4 units

This transformation is given as

g(x) = f(x + 1) + 4

Mathematically, this transformation can be represented as

(x, y) = (x + 1, y + 4)

When represented as a function, we have

g(x) = f(x + 1) + 4

Substitute the equation f(x) = log(x)

f(x + 1) = log(x + 1) + 4

So, we have the following equation

g(x) = log(x + 1) + 4
