The median is pretty much the number in the middle so it’s 15. Mode is the number that repeats the most so it’s 12. And mean is adding all the numbers together and then dividing it by how many numbers are there. So it is 23
Answer: 20 minutes
Step-by-step explanation:
An hour is 60 minutes, so (1/3)(60 min) = 20 min.
3bc is the answer to your problem
(126) times (1/2 to the x/11 power) = 15% times 126
(1/2) to the x/11 power = 0.15
Take the log of both sides :
(x/11) times log(1/2) = log(0.15)
Multiply both sides by 11 :
'x' times log(1/2) = 11 x log(0.15)
Divide both sides by " log(1/2) " :
x = 11 x log(0.15)/log(1/2) = <em><u>30.107 years</u></em> (rounded)
That's the time it takes for <em><u>any-size</u></em> sample of this substance
to decay to 15% of its original size.
