when you put something in parenthesis like C(25,8) what does that mean or how do you solve it?
i think that means how you graph it, like (x,y)
{the first is on x,second on y}
That's not what he's referring to, Gabby. David, that means out of 25, pick 8. I forget how to solve these though, so hopefully someone else will respond.
ohh, gotcha! sorry, i cant help you with that either:(
good luck!
When you see something in parentheses, like C(25,8), it usually represents a mathematical expression involving combinations. In this case, C(25,8) represents the number of ways to choose 8 items from a set of 25 items, without considering the order.
To solve C(25,8), you need to use the formula for combinations:
C(n,r) = n! / (r! * (n-r)!)
Here, n represents the total number of items to choose from (25 in this case), and r represents the number of items you want to select (8 in this case).
The exclamation mark (!) denotes the factorial of a number, which means multiplying all positive integers up to that number. For example, 5! is calculated as 5 x 4 x 3 x 2 x 1 = 120.
So, to solve C(25,8), you can substitute the values into the formula:
C(25,8) = 25! / (8! * (25-8)!)
Now, calculate the factorials:
25! = 25 x 24 x 23 x ... x 3 x 2 x 1
8! = 8 x 7 x 6 x ... x 3 x 2 x 1
(25-8)! = 17!
Finally, you can compute the combination:
C(25,8) = 25! / (8! * 17!)
You can use a calculator or a mathematical software program to compute large factorials and then divide them to get the final result.
