So basically the formula is:
3/5 = 12/n
so then we get 3n = 60
n = 20
so there are 20 picks in all

Step-by-step explanation:
This is going to be a permutation because order matters.
![_5P_5](https://tex.z-dn.net/?f=_5P_5)
The permutation formula is
![_nP_r = \frac{n!}{(n-r)!}\\_5P_5 = \frac{5!}{(5-5)!}\\ _5P_5=\frac{120}{0!=1}\\ _5P_5 = 120](https://tex.z-dn.net/?f=_nP_r%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D%5C%5C_5P_5%20%3D%20%5Cfrac%7B5%21%7D%7B%285-5%29%21%7D%5C%5C%20_5P_5%3D%5Cfrac%7B120%7D%7B0%21%3D1%7D%5C%5C%20_5P_5%20%3D%20120)
Answer:
-1
Step-by-step explanation:
(x₁ , y₁) = (1 , 3)
(x₂ , y₂) = (-1 , 5)
![Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\](https://tex.z-dn.net/?f=Slope%20%3D%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%5C%5C)
![=\frac{5 - 3}{-1-1}\\\\=\frac{2}{-2}\\\\= -1](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%20-%203%7D%7B-1-1%7D%5C%5C%5C%5C%3D%5Cfrac%7B2%7D%7B-2%7D%5C%5C%5C%5C%3D%20-1)
