Sketch the circle given by x²+y²=1 and the line given by y=2x+2 on the same set of axes. one solution to the pair of equations is easily identifiable from the sketch. what is it?

(-0.6, 0.8) and (-1,0)

Step-by-step explanation:

Applying y value to the first equation

Solving the equation

When x = -0.6

When x = -1

So, the points where the circle and line will intersect are (-0.6, 0.8) and (-1,0)

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.
