Answer: Five times any even number will result in an even number (10,20,30,40,50, etc are even numbers and multiples of five.)
That's impossible. Adding up an odd number of odd numbers will give an answer that is an odd number. 50 is an even number. So adding up 5(5 is an odd number) odd numbers will not give 50, an even number.
I got 6.8 by adding the five numbers and dividing by five.
You cannot do this, as adding five odd numbers together will give an odd result.
5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80, carry on adding five
With a total of 90,000 five digit numbers, we can conclude that there is 45,000 EVEN five digit numbers.
the first positive even numbers are 2,4,6,8,10
Even numbers are numbers that are evenly divisible by 2. The first five even numbers would be 2, 4, 6, 8, and 10.
Half of them. Every other number from 0 to 99998 is even. Since there are 90,000 five digit numbers, that means that 45,000 of them are even.
In order to find the mean of numbers, add up all of the numbers and thn divide it by the number of numbers there are. Adding two, five and twelve equals nineteen. Then divide three into nineteen, and this gives you a mean of 6.33.
Just add all the numbers, then divide by the size of the set. For example, if you have a set of five numbers, add all of them, then divide the result by five.
24680 using only even numbers or 12346 which is an even number
It's impossible. Adding 5 odd numbers will always result in an odd number. 50 is an even number. Here's how. Let the five odd numbers be: 2a+1, 2b+1, 2c+1, 2d+1, and 2e+1; where a,b,c,d & e are any whole numbers. This guarantees that they are odd, since multiplying by 2 gets and even then an even plus one will be an odd. So we have 2a+1+2b+1+2c+1+2d+1+2e+1. Rearranging we have 2a+2b+2c+2d+2e+5 = 2(a+b+c+d+e) + 5. So 2(a+b+c+d+e) is even, then you add 5 and it's odd.
Add the five numbers; divide the result by 5.
The sum of the first 500 even numbers, excluding zero, is 250,500.
Two numbers that equal 5 when adding are:0 + 5 or 5 + 0 1 + 4 or 4 + 1 3 + 2 or 2 + 3
It is 16. This is because there are five numbers between 11 and 16, and there are five numbers between 16 and 21 :]
All whole numbers can be divided by at least two numbers: 1 and the number itself. Additionally, all even whole numbers can be divided by two and all numbers ending in five can be divided by five.
You cannot. The sum of any two odd numbers is even (O+O=E), the sum of any two even numbers is even (E+E=E) and the sum of an odd and an even (or even and odd) is odd (O+E=E+O=O). O+O+O+O+O = O+O+O+O+O = E + E +O = E +O = O Addition is commutative, that is, the order in which you add the numbers does not matter. Some trial and error will demonstrate commutativity, though a proof is more complicated.
five (including 20)
All numbers ending in five are odd.
There are no 5 odd numbers that when added together make 30.Two odd numbers added together make an even numberAn odd number plus and even number makes an odd number.From the five odd numbers:Take two of them and add them together getting an even number and four odd numbersAdd another of the odd numbers to this even number and you will have three odd numbersAdd two of these together and you will have one even and one odd number.Finally add these odd and even numbers together and the result will be an odd numberBut 30 is an even number, so cannot be the sum of five (or any odd number of) odd numbers.
