Step-by-step explanation:
Answer:
The bone is 14572 years old.
Step-by-step explanation:
There is 17% as much Carbon-14 in the ancient bones as from current bones and the decay constant is given as 0.0001216 for time in years.
The equation for radioactive decay is N = N₀ e^(-λt)
where t = time in years
λ = decay constant
N = final amount of carbon
N₀ = initial amount of carbon.
There is 17% as much Carbon-14 in the ancient bones as in current bones. So,
N = 17% of N₀
N = 0.17N₀
So, N/No = 0.17.
N = N₀ e^(-λt)
N/N₀ = e^(-λt)
0.17 = e^(-0.0001216t)
ln (0.17) = -0.0001216t
-0.0001216t = -1.7719568
t = -1.7719568/-0.0001216
t = 14572 years
Answer: B
Step-by-step explanation:
A is a standard bell curve
B is skewed right because a few numbers that are larger drag the mean much more than the median
C it would be skewed left because of the reverse of b
