given: circle k(o), ed = diameter, m∠oef=32°, measure of arc ef=(2x+10)°
find: x

hey ya'll - i really need with this - i missed class and have no

Step-by-step explanation:

step 1

Find the measure of arc DF

we know that

----> Equation A

Because the diameter DE divide the circle into two equal parts

we know that

The inscribed angle measures half that of the arc comprising

substitute the given value

step 2

Find the measure of arc EF

substitute the measure of arc DF

step 3

Find the value of x

we have

equate the equations

ok

step-by-step explanation:

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.
