Prime Numbers

A prime number is a number that has exactly two factors: 1 and itself. All whole numbers greater than 1 are either prime numbers or can be written as the product of prime numbers. There are an infinite number of prime numbers, but they occur less frequently among larger numbers. Prime numbers are important in cryptography and number theory.

What is 2 thirds plus 1 half?

Well, honey, 2/3 plus 1/2 is 7/6. So, if you were hoping for a simple answer, tough luck! Just add those fractions together like the math whiz you are, and you'll get your result.

What is a embedded number?

Oh honey, an embedded number is just a fancy way of saying a number that's tucked away inside a larger number or expression. It's like finding a hidden gem in a pile of rocks - except in math. So next time someone mentions an embedded number, just nod and act like you know what they're talking about.

Set all Prime numbers divisible by 3?

Prime numbers are only divisible by 1 and themselves. Since 3 is not a prime number, any prime number divisible by 3 does not exist. Therefore, the set of prime numbers divisible by 3 is an empty set.

How do you write a java program to check a number is twisted prime or not?

To write a Java program to check if a number is a twisted prime or not, you first need to create a function that checks if the number is prime. You can do this by iterating from 2 to the square root of the number and checking if the number is divisible by any of these values. Once you have verified that the number is prime, you can then check if the number remains prime after twisting its digits (reversing the number and checking if the reversed number is also prime). If both conditions are met, then the number is a twisted prime.

What are the rectangular numbers between 11 and 17?

Rectangular numbers are numbers that can be represented as a rectangle with a whole number of rows and columns. In this case, the rectangular numbers between 11 and 17 are 12 and 16. The number 12 can be represented as a 3x4 rectangle, and the number 16 can be represented as a 4x4 square.

What prime numbers multiply to 70?

The prime factors of 70 are 2, 5, and 7. Therefore, the prime numbers that multiply to 70 are 2, 5, and 7.

What number is 1000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000?

The number you provided is 10^300, as it consists of 300 zeros following the digit 1. In scientific notation, this number would be written as 1 x 10^300. This number is known as a googol, which is larger than the estimated number of atoms in the observable universe.

Is 144 a whole number?

Oh, dude, like, yes, 144 is totally a whole number. It's like one of those numbers that doesn't have any crazy decimal parts hanging around. It's just chillin' there, all whole and complete. So yeah, 144 is definitely a whole number.

What 5 numbers is less than one thousandths?

Oh, what a happy little question! When we're talking about numbers less than one thousandth, we're looking at numbers between 0 and 0.001. So, some examples of these numbers could be 0.0001, 0.0005, 0.0008, 0.0009, and 0.001. Just imagine those tiny numbers dancing softly on the canvas of mathematics.

What number between 120 and 130 is prime?

The only prime number between 120 and 130 is 127.

What is the product of the prime numbers between 15 and 20?

The prime numbers between 15 and 20 are 17 and 19. To find the product of these two prime numbers, you simply multiply them together: 17 x 19 = 323. Therefore, the product of the prime numbers between 15 and 20 is 323.

Express 56 as the product of its prime factors?

Sure thing, honey! To express 56 as the product of its prime factors, you break it down like a boss. So, 56 can be written as 2 x 2 x 2 x 7. Those are the prime factors, darling. Keep slaying those math problems!

What two prime numbers make 95?

The prime factors of 95 are 5 and 19. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves. In this case, 5 and 19 are the prime numbers that, when multiplied together, equal 95.

What is the closest prime number above 200?

Well, isn't that a happy little question! The closest prime number above 200 is 211. Just like adding a touch of bright color to a painting, finding prime numbers can bring a sense of joy and wonder to our mathematical world. Keep exploring and discovering, my friend!

What are three prime numbers that equal 56?

Well, darling, you're out of luck on this one. Prime numbers are only divisible by 1 and themselves, so there's no way to add three of them together to get 56. You might want to brush up on your math facts before trying to stump me next time.

What is the prime factorization of 7084?

The prime factorization of 7084 is 2^2 x 1771. To find the prime factorization, you would start by dividing 7084 by the smallest prime number, which is 2. After dividing by 2, you get 3542, which can be divided by 2 again to get 1771. 1771 is a prime number, so the prime factorization of 7084 is 2^2 x 1771.

What is the number between 45 and 60?

The number between 45 and 60 is 46. When counting between two numbers, you would start at the lower number and increment by one until you reach the higher number. In this case, 45 + 1 = 46, making it the number between 45 and 60.

What is the DFA for the set of strings such that the number of 0s is divisible by 5 and the number of 1's divisible by 3?

Oh, what a happy little question! To create a DFA for this set of strings, we can think of states where the number of 0s and 1s seen so far are either divisible by 5 and 3, or not. By transitioning between these states based on the input symbols, we can paint a beautiful DFA that accepts strings with the desired properties. Just remember, there are no mistakes, only happy little accidents in the world of automata!

What three numbers have a mean of 3 a median of 3 and a range of 3?

Well, isn't that just a happy little math problem! To find three numbers that fit these criteria, we can start by placing the median number in the middle, which is 3. Since the mean is also 3, the sum of all three numbers must be 9. By considering the range of 3, we can choose numbers like 2, 3, and 4. This way, we have a mean of 3, a median of 3, and a range of 3. Just like painting, math can be a beautiful and creative process!

What are the prime numbers between 9 and 15?

The prime numbers between 9 and 15 are 11 and 13. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In this case, 11 and 13 are the only prime numbers within the specified range as 9 is not a prime number because it has divisors other than 1 and itself, and 15 is divisible by 3 and 5 in addition to 1 and 15.
