‘| |’ means modulus.
It’s turns the internal value positive.
We get a negative answer while finding the area of a triangle because there points in the quadrant other than the 1st quandrant i.e where all values are positive
Area of a triangle can never be negative, so we use modulus

Select the correct answer.

Liono4ka [1.6K]

Answer:

Option C.

Step-by-step explanation:

It is given that,

Total number of applicants = 9

Number of job = 3

We need to select 3 applicants out of 9. So, the required number of ways is

$^9P_3=\dfrac{9!}{(9-3)!}$

$^9P_3=\dfrac{9\times 8\times 7\times 6!}{6!}$

$^9P_3=9\times 8\times 7$

$^9P_3=504$

Therefore, there are $^9P_3=504$ ways the positions can be filled because the order in which the applicants are chosen matters.

Hence, the correct option is C.
