PLEASE HELP ILL MARK BRAINLIEST Cecily claims that the equation y = x+b, where b is a real number, represents a function whose graph is a straight line.
Which statement BEST classifies this claim?

A. Cecily's claim is true only when bis zero.
B. Cecily's claim is true for all values of b.
С. Cecily's claim is not true for any value of b.
D. Cecily's claim is true only when b is not zero.

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.

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

1; 35 is the ratio
