3z - 4 = 6z - 17.               First try to take all the zs to one side of the equation
                                      preferrably to the left. And the sign of any expression
                                      changes on crossing the equality sign.

3z-6z = -17+4
-3z     =  +4-17
-3z     =   - 13.                       Divide both sides by -3.
 -3z/-3   =  -13/-3
 
z = 13/3.

3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=\frac{-13}{-3z} (divided both sides by -3z)
z=\frac{13}{3}

Imagine an experiment in which one student is selected at random from among all currently enrolled students in this university.
Alex_Xolod [135]

Answer:

\left \{ x\varepsilon U;x\notin A  \right \}, \left \{ x\varepsilon U;x \varepsilon  A\cap B  \right \}, \left \{ x\varepsilon U;x \notin A, x \varepsilon B  \right \}, \left \{ x\varepsilon U;x \notin A, x \notin B  \right \}, \left \{ x\varepsilon U;x \varepsilon A \cup  B  \right \}, \left \{ x\varepsilon U;x \varepsilon (B-A)\cup (A-B)  \right \}

Step-by-step explanation:

Set refers to the well defined collection of objects.

We can express a set in set-builder form or in roaster form.

Roster form is a mathematical representation of a set that lists all of the elements of the set  within the curly bracket, separated by commas.

A set-builder notation is a mathematical representation for describing a set that lists all of the elements of the set by stating the properties that its elements must satisfy.

Let A be the event that the selected student is classified as enrolled in engineering (one of the engineering schools), and let B be the event that the same student is currently enrolled in this class.

Let U denotes the set of all students currently enrolled in the university.

1. \left \{ x\varepsilon U;x\notin A  \right \}

2. \left \{ x\varepsilon U;x \varepsilon  A\cap B  \right \}

3. \left \{ x\varepsilon U;x \notin A, x \varepsilon B  \right \}

4. \left \{ x\varepsilon U;x \notin A, x \notin B  \right \}

5. \left \{ x\varepsilon U;x \varepsilon A \cup  B  \right \}

6. \left \{ x\varepsilon U;x \varepsilon (B-A)\cup (A-B)  \right \}
