There are 40 odd numbers between 20 and 100. Remember that an odd number is every second number. There are 80 numbers between 20 and 100, so there are 40 odd numbers and 40 even numbers.
An even multiple of 20 is equal to 20 multiplied by an even number, that is 20 multiplied by 2k where k is any integer.
When there is an even number of items in the data set the median is the mean average of the middle two. The middle two are the two items themselves, namely 20 and 40, so the median is (20 + 40)/2 = 30.
To find the number that 20 is 40% of, you can set up a proportion. Let x be the number we are trying to find. The proportion would be: 20/x = 40/100. Cross multiplying gives us 100 * 20 = 40 * x. Simplifying this equation, we get x = 200 / 40 = 5. Therefore, 20 is 40% of the number 50.

No, 40 is an even number.
40 is an even number - it is divisible by 2 to produce a whole number
There are 20 odd numbers in 40.
Even numbers are numbers which are multiples of 2 (they can be divided by 2). 40\2 = 20 This means that 40 is an even number.
No.
An even multiple of 20 is equal to 20 multiplied by an even number, that is 20 multiplied by 2k where k is any integer.
There can be no number with an odd sum of 8 because 8 is not odd!
Even because it is divisible by 2.
21 23 25 27 29 31 33 35 37 39
If you add an even number with another even number, you will always get the sum as an even number. Ex: 22 + 44 = 66
That number is 36.
