Iwill award brainliest! which percent is the larger: 1. 8 “a” students out of 40, or 9 “a” students out of 50 2. 6 broken bulbs out of 20, or 7 broken bulbs out of 30 which change (in percent) is the larger: 1. increasing the price from $400 to $500 or increasing the price from $500 to $600 2. losing weight from 100 lb to 90 lb or losing weight from 50 lb to 40 lb

Part 1. 1) 8/40 2) 6/20 Part 2. 1) From 400 to 500 2) Losing weight from 50 to 40 pounds

Step-by-step explanation:

8/40 = .2

9/50 = .18

6/20=.3

7/30= .233333

500/400 = 1.25

600/500=1.2

90/100=.9 Lost 10 percent

40/50=.8 Lost 20 percent

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.
