Two hikers start a trip from a camp walking 1.5 km east. they turn north and walk 1.7 km to a waterfall. to the nearest tenth of a kilometer, how far is the waterfall from camp?

the horizontal leg (due east) = 1.5 km  

the vertical leg (due north) = 1.7 Km  

The hypotenuse is the distance from camp  

Use the Pythagorean theorem to find the length of the hypotenuse:  

waterfall's distance from camp = √(1.5² + 1.7²) = 2.3 km (to the nearest tenth)

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.

is should be y = 5x
