Answer:
Step-by-step explanation:
To convert repeating decimals to fractions, you take the numbers that are repeating, in this case 612, and you see how many numbers are repeating. Here we have 3 numbers repeating and so you would divide 612 by 3 9's meaning 999. So 0.612 repeating is equal to . To make sure the answer is right, you can divide the numbers in a calculator to make sure you get the correct decimal.
Answer:
And for this case we can use the total rule of probability given by:
And if we solve for we got:
And replacing we got:
Step-by-step explanation:
We have the following probabilities given:
And for this case we can use the total rule of probability given by:
And if we solve for we got:
And replacing we got:
The half-life of the given exponential function is of 346.57 years.
<h3>What is the half-life of an exponential function?</h3>
It is the value of t when A(t) = 0.5A(0).
In this problem, the equation is:
.
In which t is measured in years.
Hence the half-life is found as follows:
t = 346.57 years.
