What is Quartile in Maths.?

The numbers known as quartiles are used to divide the provided data set into four equal portions, or three points. Thus, the values that split the provided data into three quarters are known as quartiles. The center point of distribution is shown by the middle portion of the quartiles. The interquartile range is determined by the difference between the higher and lower quartiles so established.

Data 26, 34, 38, 49, 65, 75, 81

First arrange the data from smallest to greatest

26, 34, 38, 49, 65, 75, 81

Then find the median of the data,

Since, the data is in odd numbers median is mid term i.e. 49.

To find the third quartile we take the upper half of data

Upper half of data set, 65, 75, 81

Third quartile is the median of the upper half of the data.

Median of upper half is

Q3 = (n+1)th

Q3 =(3+1)th

Q3 = 2th term

Q3 = 75term

The expression [ (2.7) [tex]4]^{6}[/tex] is not equivalent to [ (2.7) 8 ] ³.

What are exponents?

An exponent refers to the number of times a number is multiplied by itself.

2 and 3 are exponents.

We have,

[ (2.7) [tex]4]^{6}[/tex]

Here 6 is the exponent.

We can write 6 as 2 x 3

the range of the function g(x) = x^6 is: R: [0, ∞)

What is the range of the function?

Here we have the function:

g(x) = x^6

First, notice that we have an even exponent. This means that the outcome of the function will always be a positive number, then the minimum of the range is:

g(0) = 0^6 = 6

A square acre of land is 5,280 square yards.

between 1,320 and 1,321 yards

Answers

By factor decomposition, area of a square and power and root properties, the length of the side is between 72 yards and 76 yards. (Correct choice: B)

What integers are the limits between the length of an equivalent square side of a given area?

The area of a triangle is equal to the square of its side length and the area of land is a composite number, that is, a product of prime numbers. By factor decomposition, the equivalent form of 5,280 square yards is:

5,280 = 2⁵ × 3 × 5 × 11

Then, the equivalent side is equal to the square product of the product:

x = √(2⁵ × 3 × 5 × 11)

x = √(2⁴) × √(2 × 3 × 5 × 11)

x = 2² × √(2 × 3 × 5 × 11)

x = 4√330

As for √330 is between √324 = 18 and √361 = 19, then the length of the side is between 72 yards and 76 yards.

Whole Numbers - They are the numbers represented by positive real numbers where the fractions and decimal numbers are not included.

Integer Numbers - They are the whole numbers. They are represented by zero, positive and negative numbers.

Opposite numbers - They are numbers that the distance to 0 is equal. The numbers are classified as the opposite when the sum between them is equal to zero (0).

Answers

Yes the the equation is following direct variation. Correct option is A, Yes, k = 4/9

What is Direct Variation?

The change in one quantity as a result of the change in another is known as direct variation. This implies that if one quantity increases or decreases, the other must do the same.

Direct variation describes how one quantity directly affects the other when it varies. The precise reverse of this is called inverse variation. You will discover what direct and inverse variants are in this article, along with various cases that have been solved.

4y = 9x

standard equation for direct variation is y = kx

Answers

Using proportions, it is found that:

The value of A is of 10.The value of B is of 35.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

In the first row of the table, we are given the scale factors of 1 and 1.25. From the second row, we have that the width for a scale of 1 is of 8 inches, and for a scale of 1.25 is of A, hence:

A = 1.25 x 8 = 10.

For the third row, we have that the scale of 1 is of 28 inches, while the scale of 1.25 is of B, hence:

B = 1.25 x 28 = 35.

Answer:

(4,2) and ([tex]\frac{4}{8}[/tex],[tex]\frac{2}{8}[/tex]) are lie on the line, and y = [tex]\frac{1}{2}[/tex] x , is showing the relationship of x and y coordinates of given line.

Given that

The co-ordinates of line is (0,0) and (2,1).

To find

The points that lie on the line, and The relationship between the coordinates x and y.

So, according to the question

We have,

The X and Y co-ordinates of line (0,0) and (2,1).

For finding any point that lie on line, first we have to find the slope of given line,

So, we know that

slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Where,

x₁ = 0 and x₂ = 2

y₁ = 0 and y₂ = 1

Now, putting the values, we will get

(m) = [tex]\frac{1-0}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]

m = [tex]\frac{1}{2}[/tex]

We know that, the equation of line

y-y₁ = m(x- x₁ )

y-0 = [tex]\frac{1}{2}[/tex] (x- 0)
