Ranee is building a birdcage for her parrot in the shape of a square pyramid. the height of the birdcage is 0.5 meters and it has a volume of 0.5625 cubic meters. she decides to increase the height to 1.5 meters, leaving the base the same. what is the maximum number of cubic meters in the new birdcage.

1.6875 cubic metres

Step-by-step explanation:

Given:

Ranee builds a birdcage for her parrot

Shape - square pyramid

Volume of bird cage = Area of base square x height

height = 0.5 m, and volume =0.5625 cubic metres

Hence 0.5625=0.5xArea of base square

Area of base square=0.5625/0.5 =0.1125

NOw when height become 1.5 m, new volume would be

Area of base square x new height

0.1125(1.5) = 1.6875 cubic metres.

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.
