João is studying the concept of factorial and its applications in combinatorial problems. He has come across an expression involving factorials that is intriguing his reasoning. The expression is: n! / (k!(n-k)!) = C(n,k); where "n" and "k" are natural numbers, "!" represents the factorial, and "C(n,k)" is the number of possible combinations of "n" elements taken "k" at a time.Answer sheet:

In a school, a survey was conducted on students who practiced sports. It was found that 60% of the students practiced soccer, 30% practiced volleyball, and 20% practiced both sports. If a student is randomly selected, what is the probability that he practices soccer, given that he practices volleyball?

Consider a Cartesian coordinate system where a point P has coordinates (a, b) and a point Q has coordinates (c, d). The absolute value of a number is defined as its distance from the origin of this system. If point P is in the second quadrant and point Q is in the fourth quadrant, with a, b, c, and d being integers, and it is known that the absolute difference between the y coordinates of P and Q is 15, determine the value of a - c, knowing that a < 0 and c > 0.

Consider the linear system below:
2x + 3y = 10
5x - 4y = -7
Transform this linear system into a matrix form using a matrix A and a column vector X, representing the unknowns. Write down the resulting matrix equation and inform what is the dimension of matrix A.
