Which is the meadian 32 26 20 30 388?
Arrange numbers from low to high; median is number in the middle
20 26 30 32 388
median is 30
the number 388 seems like it does not belong in this set, but the median is correct.
Do you really know all the prime numbers?
The way to know the Prime Numbers is to find out if they can only Multiplied Once ,The way to know Composite Numbers is to find out if they can be Multiplied Twice
Are all numbers that end in seven all primes?
No! Not by a long shot. With larger numbers, you cannot tell whether an odd number is prime or composite just by the last digits. All prime numbers greater than 7 must end in one or these: 1, 3, 7 or 9. But not all numbers ending with 1, 3, 7 or 9 are prime.
Extra stuff:
Well for example 207 is divisible by 3 so the answer is no (207 is 69 times three). The simple test (ie to check for 3 as divisor or also called a factor) is to add all the individual numbers up (here it totals 9) and then if that number is divisible by three then you don't have a prime number. So 27 is also not a prime - it divides by three. (quick check again the total of the numbers is 9 ie divisible by three) and another example 57 can be divided by 3 to give 19 and the quick check is 5 and 7 totals 12 which is then divisible by three.
ps don't forget you need to check for all the other numbers also! ie like 4, 5, 7, 9, 11, 13 ... etc
What is the meaning of prime and composite?
When referring to positive integers, prime means having only two factors and composite means having more than two.
Is the number 111 a prime composite or neither?
It is a composite number because it has more than two factors
How do you check if a large number is prime or a composite number?
You divide the number by 2. If the number is able to divide WITHOUT a remainder, then it is a prime number. If you divide a number by 1, you will get the same number. That is not a prime number.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
What are the prime and composite numbers of 91?
91 is the only composite factor of 91.
7 and 13 are prime.
What are the composite numbers of 47 and 51?
47 is a prime number and is divisible by 1 and 47 only.
51 is divisible by 1, 3, 17, 51.
Is 215 a prime number or composite number?
215 is a composite number because it has other factors aside from 1 and itself. The other factors of 215 are 5 and 43.
The sum of the fractional parts of two integers is what?
Integers have no fractional parts, so their sum will be zero.
How do you conver a composite number to a prime factorization?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.
What is largest prime or composite number between 18 and 24?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. The largest prime number between 18 and 24 is 23.
What the set of all even counting numbers?
The set of all even counting numbers is infinite. There's not enough room to list them here.
ANSWER: No.
