A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bul
bs would the robot be expected to find in a batch of 15 bulbs?
1 answer:
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26
Total examined = (flawed + not flawed)
Total examined = (4 + 26) = 30
P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2

if we're going by a 24 pack of soda, 3/8 would be 9 sodas while 4/12 is a third, which would be 8 sodas
14 because - 11-17=-28. If you divide -28 by -2x you get 14
Answer:
24 divided by 2/3 would be 36, so 36 days
