The line y = -4x -20 meets the x - axis at the point P. Write out the coordinates of P.

P (- 5, 0 )

Step-by-step explanation:

To find where the line meets the x- axis, let y = 0 , that is

- 4x - 20 = 0 ( add 20 to both sides )

- 4x = 20 ( divide both sides by - 4 )

x = - 5

The coordinates of P are (- 5, 0 )

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
