Answer:
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
Step-by-step explanation:
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
![P_{(n,x)} = \frac{n!}{(n-x)!}](https://tex.z-dn.net/?f=P_%7B%28n%2Cx%29%7D%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-x%29%21%7D)
In this question:
Permutations of four letters from a set of 12 letters. So
![P_{(12,4)} = \frac{12!}{(12-4)!} = 11800](https://tex.z-dn.net/?f=P_%7B%2812%2C4%29%7D%20%3D%20%5Cfrac%7B12%21%7D%7B%2812-4%29%21%7D%20%3D%2011800)
11,800 different four letter permutations can be formed using four letters out of the first 12 in the alphabet
16/80 = 1/5 just put it into the calculator
Answer:
The answer is Simulation study.
Step-by-step explanation:
Substitute the values into the equation
2(2)+4(-1)-5(1)
4-4-5
-5
I'm not sure does anyone else know the answer?
