Hello can anybody me solve this problem? and you

8 units^2

Step-by-step explanation:

First, let's find the are of the square. We know the side lengths are 2 and 2 so we do 2*2 to get 4. Now we can look at the triangles on the left and right. If you notice, you can take one triangle from the left side, flip it and connect it to the triangle on the right side, (kind of like a puzzle) forming a square. The side lengths of that square of 2 and 2, so we do 2*2 to get 4. 4+4=8. The area of the trapezoid is 8 units^2

the answer is b i just did that

step-by-step explanation:

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.
