Find the area of the figure a) 45 square inches b) 60 square inches c) 90 square inches d) 225 square inches

C

Step-by-step explanation:

To calculate the area of a parallelogram, use A = b*h where h is a perpendicular height. For one parallelogram the base is 15 inches and the height is 3 inches. There are two of equal area so multiply by 2.

A = 15(3)(2) = 90 square inches

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.
