worth 20 pts match each polynomial with its factorization. ***match the letters to the numbers*** ex. 3 is b ( for example only) 1. y^2 - y - 2 2. 3y^2 - 27 3. y^4 - 16 4. y^2 - 12y + 36 5. -4y^2 + 8y + 32 6. 5y - 2 + 4y^2 - 4 a. (y - 2)(y + 2)(y^2 + 4) b. -4(y + 2)( y - 4) c. (4y - 3)(y + 2) d. 3(y - 3)(y + 3) f. (y - 6)^2 g. (y + 1)(y - 2)

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

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.
