Solve for the value of x.
(8x+2)
34°

x = 18

Step-by-step explanation:

The angle of a straight line is 180°, if we already know that one of the two angles is 34°, then the other angle must be equal to (180 - 34) = 146°

To solve for x

8x + 2 = 146; subtract 2 from both sides

8x = 144; divide by 8

x = 18

its 4 because 2 times 2 is 4, if you double the number two you get four

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.
