Answer these and you get a cool surprise

2. is 7 ft

3. is sqrt(180) or 6sqrt(5)

Step-by-step explanation:

Both go by the rules of a^2+b^2=c^2,

for the 1st question, c=25 and b=24, so we're trying to find a, 25^2-24^2=49=sqrt of 49=7

for the 2nd, we have a and b already, so 36+144=180, c= sqrt(180) --> 6sqrt(5)

hope it sort of helped!

10

Step-by-step explanation:

I think 10 bc a squared plus b squared equals c squared

after that you divide it by a plus b

I did this and got 10

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.
