Ascientist measured the width of a square flake of gold to be7.3 x 10 -4mm what is the area of the flake

The area of square flake of gold is

Given that width of square flake of gold is millimeter

To find : Area of square flake

Since gold flake is in shape of square, we can use area of square formula

The formula for area of square is given as:

where "s" is the length of one side

Hence , the calculated area of flake is

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.

i think the amount would be $140.62
