Which describes the slope of this line? number graph ranging from negative three to one in increments of point five on the x axis and negative two to two in increments of point five on the y axis. a vertical line is drawn between x equals negative one and x equals negative one point five. a. positive slope b. undefined slope c. zero slope d. negative slope

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.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
