The average temperature on mars is -67 degrees Fahrenheit. Earths average temperature is 61 degrees Fahrenheit. How many degrees warmer is the average temperature of earth is earth than mars?

The answer to your question is 128°F

Step-by-step explanation:

Data

Temperature on Mars = -67°F

The Temperature on Earth = 61°F

Process

1.- Subtract the temperature of Mars to the temperature of the Earth.

                      ΔT = 61 - (-67)            

2.- Simplification

                      ΔT = 61 + 67

3.- Result

                      ΔT = 128°F

4.- Conclusion

The Earth is 128°F warmer than Mars.    

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.
