A histogram is used to represent the distribution of continuous data, typically grouped into intervals or bins. Let's analyze the given scenarios:
(i) The number of letters for different areas in a postman’s bag:
(ii) The height of competitors in an athletics meet:
Therefore, for the height of competitors in an athletics meet, a histogram would be more appropriate to show the distribution of heights.

To determine if the points (5, 4) and (4, 5) represent the same point, we can compare their coordinates.
The point (5, 4) has coordinates (x, y) = (5, 4), while the point (4, 5) has coordinates (x, y) = (4, 5).
Since the order of the coordinates matters, these points are different. The first point is located at (5, 4), and the second point is located at (4, 5). Therefore, they do not represent the same point in a Cartesian coordinate system.

To find a 5-digit number divisible by 11 with the given digits (2, 3, 4, 5, 6), we can use the following approach:
Alternate Sum Method:
Example: 6−5+4−3+2=46−5+4−3+2=4.
Check Divisibility:
Let's apply the method:
Since 4 is not divisible by 11, let's try another arrangement until we find a suitable number.
After a few iterations, we find the arrangement 5, 6, 4, 3, 2, which yields 2−3+4−6+5=22−3+4−6+5=2. This number, 56432, is divisible by 11.

As a registered tutor on UrbanPro.com specializing in Class 7 Tuition, I understand the importance of providing clear and structured explanations for mathematical problems. Let's delve into the factorization of the given polynomial expression:
Factorize the polynomial expression: 54x² + 42x³ – 30x⁴
The first step in factoring a polynomial is to identify the common factor of all the terms. In this case, the common factor is 6x².
Now, we need to factorize the quadratic expression inside the parentheses. For this, we can use methods like grouping or the quadratic formula.
Combine the factored common factor with the factored quadratic expression:

As a seasoned tutor registered on UrbanPro.com, I specialize in providing top-notch online coaching for Class 7 Tuition. Today, I'll guide you through the process of factorizing the expression: 2x²yz + 2xy²z + 4xyz.
To factorize the given expression, we'll look for common factors in each term and factor them out.
Identify Common Factors
Factorize the Expression
2xyz(x + y + 2) Common Factor of 2: Factoring out 2 helps simplify the expression and identify a common factor in each term.
Common Factor of xyz: Each term contains a factor of xyz. Factoring this out leaves us with the expression (x + y + 2).
Final Factored Expression: Combining the common factors, the fully factorized expression is 2xyz(x + y + 2).

Greetings! I am an experienced tutor registered on UrbanPro.com, specializing in Class 7 Tuition and online coaching. Below is a detailed explanation of how to factorise the given expression: 30xy – 12x + 10y – 4.
Factorising is a fundamental concept in algebra, involving the decomposition of an expression into its constituent factors. In this case, we are tasked with factorising the expression 30xy – 12x + 10y – 4.
Identify Common Factors:
Observe the expression and identify common factors shared by all terms.
Example: 2(15xy−6x+5y−2)2(15xy−6x+5y−2)
Grouping Terms:
Group the terms that share common factors.
Example: 2(15xy−6x)+2(5y−2)2(15xy−6x)+2(5y−2)
Factor Out the Greatest Common Factor (GCF) from Each Group:
Factor out the common factor from each group.
Example: 2⋅3x(5y−2)+2(5y−2)2⋅3x(5y−2)+2(5y−2)
Identify and Factor Out Common Binomial Factor:
Notice the common binomial factor in both groups.
Example: 2(3x+1)(5y−2)2(3x+1)(5y−2)
By following these steps, the given expression 30xy – 12x + 10y – 4 can be factored as 2(3x+1)(5y−2)2(3x+1)(5y−2).

To simplify the expression 12(y2+7y+10)6(y+5)6(y+5)12(y2+7y+10), you can start by simplifying the coefficients and factoring the quadratic expression in the numerator:
12(y2+7y+10)6(y+5)6(y+5)12(y2+7y+10)
First, factor the quadratic expression in the numerator:
12(y2+7y+10)=12(y+5)(y+2)12(y2+7y+10)=12(y+5)(y+2)
Now, substitute this factorization back into the original expression:
12(y+5)(y+2)6(y+5)6(y+5)12(y+5)(y+2)
Next, simplify the coefficients and cancel out common factors:
2(y+5)(y+2)y+5y+52(y+5)(y+2)
Finally, cancel out the common factor of (y+5)(y+5):
2(y+2)2(y+2)
So, the simplified expression is 2(y+2)2(y+2).
