Each point (or pair) in a proportional relationship must share the same

difference ⇒ last answer

Step-by-step explanation:

Lets explain the meaning of proportional relationships

- Two quantities have a proportional relationship if they can be

  expressed in the general form y = k x, where k is constant

- From y = k x, then , where k is constant that

  means the quantities are always share the same ratio k

- The graph of the y = k x must be a line, then the graph of a

   proportional relationship must be a line

- If x = 0 then y must be equal zero, that means the graph of a

  proportional relationship must pass through (0 , 0)

- Sometimes the two quantities share the same difference but not

  share the same ratio then they are not in proportional relationship

- Ex: (0 , 4) , (2 , 10) , (4 , 16) , (6 , 22) all the ordered pair share the

  same difference in x and y but ≠

  ≠   ≠ , then they don't share the same ratio

Now lets find the false statement

A proportional relationship must graph as a line ⇒ True

A graph of a proportional relationship must pass through (0 , 0) ⇒ True

Each point (or pair) in a proportional relationship must share

the same ratio ⇒ True

From the example above:

Each point (or pair) in a proportional relationship must share the

same difference ⇒ False

The false statement is

Each point (or pair) in a proportional relationship must share

the same difference

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.
