Pls help D: One side of a triangular piece of cloth is 15 inches. The second side of the cloth is 36 inches.
15 in.
O
36 in
O
What length, in inches, should the missing side of the cloth be to ensure that the angle formed by
the 15-inch side and the 36-inch side is a right angle?

x = 39 in

Step-by-step explanation:

15² + 36² = x²

225 + 1296 = x²

1521 = x²

= x

39 = x

Hope this helps!

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.
