Y can be rounded up to 1.51 from a minimum value of 1.505
This is the lower bound.
y can be rounded down to 1.51 from a maximum value of 1.515
this is the upper bound.
y is between the lower bound and the upper bound so y is between 1.505 and 1.515
This is shown as 1.595<=y<1.515
<= is the typed out version of (greater than/equal to) which is < with a line under it.
Answer: 41.5 min
Step-by-step explanation:
This problem can be solved with the Radioactive Half Life Formula:
(1)
Where:
is the final amount of the radioactive element
is the initial amount of the radioactive element
is the time elapsed
is the half life of the radioactive element
So, we need to substitute the given values and find from (1):
(2)
(3)
(4)
Applying natural logarithm in both sides:
(5)
(6)
Clearing :
This is the time elapsed
