Answer:
There are 604,800 possible permutations.
Step-by-step explanation:
The order in which the digits are chosen is important, which means that the permutations formula is used to solve this question.
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:
7 digits from a set of 10(10 digits to 0-9). So
![P_{(10,7)} = \frac{10!}{(10-7)!} = 604800](https://tex.z-dn.net/?f=P_%7B%2810%2C7%29%7D%20%3D%20%5Cfrac%7B10%21%7D%7B%2810-7%29%21%7D%20%3D%20604800)
There are 604,800 possible permutations.
My best guess is D.goes down and to the right

Answer:
n=-7
Step-by-step explanation:
For this you can do the inverse of division which is division. So Divide -91 and 13. Which is -7.
