Emma spent 4 1/2 days planting her garden her brother spent 2/9 as much time as Emma did how many how many days did her brothers been planting the garden

1 day

Step-by-step explanation:

So first you know Emma planted for 4 1/2 days and her brother 2/9 times as much so I think we should do this:

4  1/2 convert to improper fraction = 9/2

             -Then-

multiply 9/2 x 2/9 = 18/18 = 1 day

Hope this helped :D

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.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
