Convert 59 degrees in Fahrenheit to Celsius temperature using the formula F=9/5c+32.

15° C.

Step-by-step explanation:

To do this, we will need to plug in and solve.

59 = 9/5c + 32

Isolate the variable by subtracting 32 by both sides:

27 = 9/5c.

Divide both sides by 9/5, giving you:

15° C.

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.
