Which statements are true regarding undefinable terms in geometry? check all that apply.

a point in the form (x, y) has two dimensions.
a plane has a definite beginning and end.
a line has one dimension, length.
a point consists of an infinite set of lines.
a plane consists of an infinite set of lines.

The answer is C and D

after simplifying it i got: -36.25 as my answer. hope that !

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.
