Help Find the product of the following :

a. (-23) x 93

b. (- 16 ) x (- 30)

c. 14 x (- 12)

a)-2139

b)480

c)-168

Step-by-step explanation:

a)-×+=-

b)-×-=+

c)+×-=-

(a) -2139 (b) 480 (c) -168

Step-by-step explanation:

(a)

-23 x 93 = -2,139 ( negative and a positive make a negative )

(b)

-16 x - 30 = 480 ( two negatives cancel out and make a positive!! )

(c)

14 x -12 = -168 ( negative and a positive make a negative

hope that helps!!

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.
