In the computer lab, there are 14 apple computers and 16 pc computers . approximately what percent of the computers are pcs?

approximately 53.33%

Step-by-step explanation:

In the computer lab, there are 14 Apple computers and 16 PC computers.

Total computers in the  computer lab = 14 + 16

                                                               = 30 computers

Percentage of the computers that are PCs =

                                                                      = 0.5333333 × 100

                                                                      = 53.33%

PC computers are approximately 53.33% in the computer lab.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

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.
