Answer:616 cm²
Step-by-step explanation:
For 4 4 to 5 16 to 20 24 to 30
The best way to do this is to set up a proportion
420 x
------ = ------
600 100
then cross multiply and divide
420 times 100 = 42000/600=70
the correct answer is C. 70 people
I hope I've helped!
The probability that the bulb is good is 12/15.
Since we have taken 1 item out the remaining total is now 14, so the probability of getting a defective bulb is now 3/14.
Now you multiply the probabilities together to get (12/15)(3/14)=(4/5)(3/14)=12/70=6/35
It would be B. 120 you would usually round up but the closest one to 129.02083 is 130 and since there is no 130 it would be 120
