26.85in

Step-by-step explanation

7 plus 7 plus plus 5 equals 19 plus the semi circle of 7.85

33.817477042 (round however needed)

Step-by-step explanation:

Parallelogram: 7 plus 7 plus 5 plus 5 is 24. Then calculate the circumference of the circle: pi(radius squared), half that and add it to 24 to get your answer.

answer: t=3

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.
