Answer:
The description of the frame of reference is characterized below.
Explanation:
- Accuracy, as well as regression coefficients, seem to be the new standard measures besides summing up the validity of the developed modeling techniques.
- Classification accuracy unfortunately due to the presuppositions established by professionals on data sources with such an equitable classification process on supervised learning mostly with completely skewed category apportionment
Based on the observations made and experiments performed over the last

Answer: The half-life of beryllium-15 is 400 times greater than the half-life of beryllium-13.</h2>
Explanation:
The half-life of a radioactive isotope refers to its decay period, which is the average lifetime of an atom before it disintegrates.
In this case, we are given the half life of two elements:
beryllium-13:
beryllium-15:
As we can see, the half-life of beryllium-15 is greater than the half-life of beryllium-13, but how great?
We can find it out by the following expression:
Where is the amount we want to find:
Finally:
Therefore:
The half-life of beryllium-15 is <u>400 times greater than</u> the half-life of beryllium-13.
