What is the simplified form of the expressions?

(ignore what i already put)

your answer is correct.

Step-by-step explanation:

2^ -3= 1/8

(5.5)^ 0= 1

A.

a - 1/8

b - 1

Step-by-step explanation:

a-

the negative is applied to the closes base, which leads to

1/2^3

which equals 0.125 or 1/8

b-

any number to the power of 0 is 1

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.

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
