During a snowstorm, Owen tracked the amount of snow on the ground. When the storm began, there were 3 inches of snow on the ground. Snow fell at a constant rate of 3 inches per hour until another 9 inches had fallen. The storm then stopped for 6 hours and then started again at a constant rate of 2 inches per hour for the next 4 hours. As soon as the storm stopped again, the sun came out and melted the snow for the next 4 hours at a constant rate of 2 inches per hour. Make a graph showing the inches of snow on the ground over time using the data that Owen collected.

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.

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

30 people weigh 160 pounds or more

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
