Answer:

$\boxed{\boxed{ x=\frac{C-By}{A}; A\neq 0}}$

Step-by-step explanation:

$Ax+By=C\\\\Ax+By-By=C-By\\\\Ax=C-By\\\\\frac{Ax=C-By}{A}\\\\\boxed{ x=\frac{C-By}{A}; A\neq 0}$

Karolina [17]

The probability that he receives an invitation to work in a bank given that he defends his diploma excellently is $\mathbf{0. \overline 6}$

The known parameters are;

The probability that a graduate of the Faculty of Finance will defend the diploma excellently, P(A) = 0.6

The probability that he will defend perfectly and receive an invitation to work at a bank, P(A∩B) = 0.4

The unknown parameter is;

The probability that the student will receive an invitation from the bank given that the student defend the diploma excellent, $\mathbf {P(B \ | \ A)}$

The process

$\mathbf{ P(B \ | \ A)}$ is found using the conditional probability formula as follows;

$\mathbf {P(B \ | \ A) = \dfrac{P(A \cap B) }{P(A)}}$

Plugging in the values, we get;

$P(B \ | \ A) = \dfrac{0.4 }{0.6} = \dfrac{2}{3} = 0. \overline 6$

The probability that the student will receive an invitation from the bank given that the student defend the diploma excellent, $P(B \ | \ A)$ = $\mathbf {0. \overline 6}$
