Explanation

Mode is the value that appears most frequently in a data set.

It represents the highest frequency among all values.

Explanation

In Maths, a straight angle is an angle equal to 180°.

It is called straight because it appears as a straight line.

Explanation

To find the sum of the four numbers, multiply the average by the total count of numbers:

Average = 24

Total count = 4

Sum = Average × Total count

Sum = 24 × 4

Sum = 96

Explanation

Explanation

A pie graph (or pie chart) is divided into sectors, where each sector represents a part of the whole.

The size of each sector corresponds to the proportion of the category it represents.

Explanation

The average is the sum divided by the number of quantities:

Average = Sum / n

115 = 1840 / n

To find 'n', multiply both sides by 'n' and then divide by 115:

n = 1840 / 115

n = 16

Explanation

Convert to a common denominator: 3/8 + 4/2 = 3/8 + 16/8.

Add the fractions: (3 + 16) / 8 = 19/8.

Explanation

To find the area of the strip:

1. Calculate the area of the larger rectangle (including the strip):

New length = 82 + 2_4 = 90 cm

New width = 75 + 2_4 = 83 cm

Area of larger rectangle = 90 * 83 = 7470 cm²

2. Calculate the area of the original rectangle:

Area = 82 * 75 = 6150 cm²

3. Find the area of the strip:

Area of strip = Area of larger rectangle - Area of original rectangle

= 7470 - 6150

= 1320 cm²

Explanation

The factors of 16 are 1, 2, 4, 8, and 16, and the prime factorization of 16 is 16 = 2 × 2 × 2 × 2.

Explanation

A trapezium (also called a trapezoid in some regions) has only one pair of parallel sides.

The other two sides are not parallel, distinguishing it from other quadrilaterals like parallelograms or rhombuses.
