1. the y-coordinate for an ordered pair in the solution set of
x+2y=11 is 4. find the x-coordinate.
(1) 3
(2) 5
(3) 7
(4) 9

lol

A) x=3

Step-by-step explanation:

x+2y=11

x+2(4)=11

x+8=11

x=11-8

x=3

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.

answer: 48

just remember to use pemdas:

parentheses
