Find the length of the third side to the nearest tenth.

The answer to your question is  b = 9.5

Step-by-step explanation:

Data

hypotenuse = 10

leg 1 = 3

Process

1.- To solve this problem use the Pythagorean theorem.

             c² = a² + b²

c = hypotenuse = 10

a = 3

b = x

2.- Solve for b

              b² = c² - a²

3.- Substitution

              b² = 10² - 3²

4.- Simplification

               b² = 100 - 9

               b² = 91

5.- Result

               b = 9.5

step-by-step explanation:

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.
