PART 2.2. HELP ASAPP. Explain how you know if a triangle is
is acute obtuse or right using the converse of the pythagorean theorem.

A^2+b^2<c^2 means it's acute

A^2+b^2>c^2 means it's obtuse

A^2+b^2=c^2 means it's right

Step-by-step explanation:

Step-by-step explanation:

under 90 is acute

over 180 is obtuse

exactly 90 is a right triangle

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.

the answer would be 44.79
