An odd number plus an odd number always equals an even number. So if I add 4 odd numbers together, it's like adding two even numbers together. Even plus even equals even. That's a total of 4 odd numbers added together. So now I have one more odd number to add to my sum (an even number). Odd plus even equals odd.

(b) If the right side is like the original except that it is multiplied by -1, then it is an odd function, and is reflected in the origin. (c) If neither (a) or (b) apply then it is neither an even function or an odd function. f(x) = x 5 1. f(-x) = (-x) 5 2. f(-x) = -x 5 That's the right side of the original multiplied through by -1. Therefore ...

Here we are asked to find five odd numbers; therefore the difference between each number will be 2. If x = the middle number, then first number = x-4 second number = x-2 third number = x fourth number = x+2 fifth number = x+4 And we are told that the sum = 50. (x+x+x+x+x) + (-2+2) + (-4+4) = 50 5x = 50 (see how handy setting x=middle # can be ...

a+b+c+d+e, will always be an odd number. It could not be 100. Finding 5 consecutive even numbers that add to 100 would be easier; 16+18+20+22+24=100. If you do not say they are consecutive, there are many solutions. You could find 4 odd numbers that add to 100 (21+23+27+29=100), but not four consecutive odd numbers.

It makes you think that you are to add 5 of those and get 30. That's impossible. Here's why: Any ODD number of ODD numbers will always have an ODD sum. Since all those numbers are ODD and if you were to use an ODD number, 5, of them, you would always get an ODD number. Since 30 is EVEN, you would never get a sum of 30 by adding 5 ODD numbers.

Step 2. There are a total of 20 odd numbers (5 odd numbers per suit)or 20 possible outcomes out of the 52 cards. Step 3. Then the . Step 4. ANSWER: The probability of drawing an odd number is . Note if we count the face cards as odd (Jack and King) then there are eight more outcomes or now a total of 28 outcomes out of 52.

the probability of drawing the first odd ticket is 5/9. once you draw that ticket, without replacement, then then there are 4 odd tickets left out of a total of 8, so the probability of getting an odd ticket on the second draw is 4/8. 5/9 * 4/8 = 20/72 = 5/18 5C2/9C2 = 10/36 = 5/18 they're the same. with your card problem, there is no replacement.

Question 885341: How can we get a sum of 30 by adding odd numbers from 1 to 15 and repeating any number any number of times and adding the numbers just five times Answer by Alan3354(69443) (Show Source):

You can put this solution on YOUR website! Let 5 consecutive odd number be, x,x+2,x+4,x+6,x+8. sum of integers = 5x + 20 = 95

check.mathematically..an odd number is given by 2n+1..so 5 times that is 5(2n+10)=10n+5..10n being always even ,when 5 is added to it it will become odd and never even . it is only by guess you can do taking first 5 consecutive positive odd numbers to get a sum of above 32 we get 3+5+7+9+11=35..so we take -1+1+5+7+9+11=32..as the answer
