Mrs. ripple was analyzing how much better the dodgers or than the giants. she noticed that the dodgers won five out of every seven games that they played against them. if the dodgers won 40 games against the giants how many games were played between the two teams?

The Answer is: 56 games between the two teams.

Step-by-step explanation:

Set up a ratio on both sides of the equal sign:

5 / 7 = 40 / x

5 * x = 40 * 7

5x = 280

x = 280 / 5 = 56.

Another way to solve it:

5 / 7 multiply by 8/8 to get 40 / 56.

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.
