The answer is B. 120
nCr = n! / ((r! * (n - r)!)
n = 10
r = 3
10C3 = 10! / ((3! * (10 - 3)!)
= 10! / ((3! * 7!)
= (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1 * 7 * 6 * 5 * 4 * 3 * 2 * 1)
= 3628800 / 30240
= 120
36 different outcomes.
6 x 6 = 36
Each side of dice 1 could have a counter match of 6 possibilities x 6
For this question you should say:
52/100 = 39/?
so ? is your answer and you will have:
? = 39*100/52 = 75 and that's the answer :)))
i hope this is helpful
have a nice day
Third option is the correct answer.
Answer:
![y = \bigg[ \frac{2b}{(2a - c)} \bigg]x - \bigg[ \frac{2bc}{(2a - c)} \bigg]](https://tex.z-dn.net/?f=%20y%20%3D%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5Dx%20-%20%5Cbigg%5B%20%5Cfrac%7B2bc%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5D)
Step-by-step explanation:
![y - y_1 = m(x - x_1) \\ \\ y - 0 = \bigg[ \frac{2b}{(2a - c)} \bigg] (x - c) \\ \\ y = \bigg[ \frac{2b}{(2a - c)} \bigg]x - \bigg[ \frac{2b}{(2a - c)} \bigg]c \\ \\ \purple { \boxed{ \bold{y = \bigg[ \frac{2b}{(2a - c)} \bigg]x - \bigg[ \frac{2bc}{(2a - c)} \bigg]}}} \\](https://tex.z-dn.net/?f=y%20-%20y_1%20%3D%20m%28x%20-%20x_1%29%20%5C%5C%20%20%5C%5C%20y%20-%200%20%3D%20%20%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5D%20%20%28x%20-%20c%29%20%5C%5C%20%20%5C%5C%20y%20%3D%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5Dx%20-%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5Dc%20%5C%5C%20%20%5C%5C%20%20%5Cpurple%20%7B%20%5Cboxed%7B%20%5Cbold%7By%20%3D%20%5Cbigg%5B%20%5Cfrac%7B2b%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5Dx%20-%20%5Cbigg%5B%20%5Cfrac%7B2bc%7D%7B%282a%20-%20c%29%7D%20%5Cbigg%5D%7D%7D%7D%20%5C%5C%20)
