I Prefer Something Odd Trivia Quiz

Answer: always an odd number

An odd number multiplied by an odd number will always result in an odd number, regardless of the number or how many times it is being multiplied. Therefore, an odd number raised to any integer power (whether odd or even) will always result in an odd number.

Answer: 3

Three is the first odd prime number. To be a prime number, the number can only be divisible by one and by itself. Three is divisible by one and itself and no other numbers; therefore, it is a prime number. The number 1 doesn't fit the condition (since 1 and itself are the same number), so it is not a prime number.

Answer: Decimals are neither odd nor even

To be either odd or even, a number must be a whole number. By definition, a whole number cannot be a decimal. Whole numbers only consist of natural numbers (and zero) and their negative counterparts. Therefore, decimals are neither odd nor even.

Answer: 1, 3, 5, 15

Factors of a number are numbers that divide into the original number without a remainder left over. One and the number itself are always factors. Three and five are also factors here, since 15 / 5 = 3 and also 15 / 3 = 5.

Answer: 7

To determine if a number is happy, you must take each digit and square it. Then, add the numbers together. Continue the process until the numbers repeat or the number equals 1. If the number equals 1, then it is a happy number. If the numbers repeat, then it is a sad number.
Seven is a happy number as shown below.
7^2 = 49
4^2 + 9^2 = 97
9^2 + 7^2 = 130
1^2 + 3^2 + 0^2 = 10
1^2 + 0^2 = 1

49 is also a happy number; however, it is not the first odd happy number. However, 3 and 11 are sad numbers.

Answer: 27

A perfect cube is a number in which you can take the cube root, and the result is a whole number. For example, 27 is a perfect cube, since taking the cube root of that number gives you an answer of 3. In other words, 3*3*3=27. Other perfect cubes are 1 (1*1*1), 8 (2*2*2), and 64 (4*4*4).

Answer: Yes

o = 15 and d = 4.
15 + 4 + 4 = 23, which is an odd number. Therefore, odd does indeed add up to an odd number.

Answer: x^2-4x+3 = 0

To solve problems in the form Ax^2 + Bx + C = 0, you must factor the equation. When you factor x^2-2x+3, you get the factors (x-3)(x-1). This means that the roots 3 and 1, both of which are odd numbers.
X + 3 = 5 has a root of 2. x^3 = 8 also has a root of 2. Finally, x^2+7x+10 has two roots: 5 and 2. While 5 is odd, 2 is not.

Answer: noses

The typical human body has only one nose but two ears, legs, and arms. Although the nose consists of two nostrils, there is still only one nose. Humans also have an odd number of toes on a foot, fingers on a hand, and a single mouth.

Answer: 50%

If you were to take 50% of 6, then you would get 3, an odd number. Taking 25% of a pizza would give you a fraction (3/2). Taking 0% (none of it) or 100% (all of it) would give you an even number of slices left (6 and 0, respectively).
