Explanation

An equilateral triangle has all three sides and angles equal (each angle = 60°).

It is commonly used in geometry and structural design for uniform load distribution.

A scalene triangle has no equal sides and no equal angles.

All sides and angles are of different lengths and measures.

Explanation

1 mile = 1,609.34 meters = 160,934 cm.

Used in unit conversions for distance measurements.

Explanation

13 mod 5 = 3

17 mod 5 = 2

(13 × 17) mod 5 = (3 × 2) mod 5

= 6 mod 5

= 1

Explanation

a = 3, r = 2

3, 6, 12, 24, 48

Explanation

The number of ways to choose 2 elements from 5 is 5C2 = 5! / (2! × 3!) = 10.

This represents the combinations where order does not matter.

Explanation

The number of arrangements of 4 distinct books is 4! = 4 × 3 × 2 × 1 = 24.

This represents all possible permutations of the books on the shelf.

Explanation

Mode = 11, Mean = 12

Using:

Mean - Mode ≈ 3(Mean - Median)

12 - 11 = 3(12 - Median)

1 = 36 - 3Median

3Median = 35

Median = 35/3

= 11.67

Explanation

When class frequencies vary widely, weighting each class by its frequency gives a more accurate central tendency.

Weighted mean accounts for differences in data distribution across classes.
