Dental attrition can be used to estimate the age of subadults analysis of the epiphyseal union
<h3>What is epiphyseal union?</h3>
Epiphyseal union can simply be defined as the secondary ossification of bone in juveniles and primary means of estimating age of subadult post-cranial remains.
Below are the four stages used in the analysis of epiphyseal union:
- Nonunion with no epiphyses
- Nonunion with separate epiphyses
- Partial union
So therefore, dental attrition can be used to estimate the age of subadults analysis of the epiphyseal union

Answer:
b) the standard deviation of the sampling distribution of the mean
Explanation:
Typically, the standard error of the mean is a term in statistics that describes the deviation in the sample mean from the actual mean of a population.
Therefore, in this case, the standard error of the mean is "the standard deviation of the sampling distribution of the mean."
Answer: 1/6
Explanation:
The question is asking how much of the whole circumference is arc AB given that it's central angle is 60°. We can see that the angle is
of the whole. This means that if there were 360 equal sectors, or slices, of the circle, then this angle would take 60 of them.
From this, we can see that if the circumference was divided into 360 equal parts, then the arc would also take up 60 of them, making the arc
, or
.
We could have alternatively seen that the ratio of arc length to the whole circumference would be the same as the ratio of the central angle to the "whole angle" or 360°.
![\frac{Arc\hspace{0.1cm}Length}{Circumference}=\frac{Central\hspace{0.1cm}Angle}{360}](https://tex.z-dn.net/?f=%5Cfrac%7BArc%5Chspace%7B0.1cm%7DLength%7D%7BCircumference%7D%3D%5Cfrac%7BCentral%5Chspace%7B0.1cm%7DAngle%7D%7B360%7D)
Putting in 60 for the central angle, we get
![\frac{Arc\hspace{0.1cm}Length}{Circumference}=\frac{6}{360}=\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7BArc%5Chspace%7B0.1cm%7DLength%7D%7BCircumference%7D%3D%5Cfrac%7B6%7D%7B360%7D%3D%5Cfrac%7B1%7D%7B6%7D)
The question is asking what fraction of the circumference is the arc length, so let's isolate the arc length by multiplying the circumference to both sides
![Arc\hspace{0.1cm}Length=\frac{1}{6}*Circumference](https://tex.z-dn.net/?f=Arc%5Chspace%7B0.1cm%7DLength%3D%5Cfrac%7B1%7D%7B6%7D%2ACircumference)
This equation in words says that the arc length is one sixth of the circumference, which is exactly what the question is asking.
