# Forensic Mysteries

What we have learned so far this year in algebra 1, 8th grade. We had reviewed many things that was learned last year, as making equations, substitution, absolute value, simplifying equations, and also ratio and fractions. Another thing we learned is the way that forensic scientists identify people, just by using the bones, and an equation. By doing that you can find the height of the person.

Forensic Equations are for finding out the height or the closest number to the height of the actual person of which the bone belongs to. Forensic scientist use it to find out the person in a crime scene, or to identify who the bone belongs to.

These equations work well for most situations, because they are based on the information given. Which means that they include the information into the equations. Some possible sources of error might come into focus. For instance the miss measuring the persons height, or calculating something wrong. Another thing is the possibility that the bone is not actually that height, since for some people they’re upper body is larger or longer than they’re lower body.

Scientists and mathematicians could improve the accuracy of the equations by taking the average of every race, and ethnic group in the world in order to have even more specific data, not like many different people into one category since it could range in many different lengths. Like for instance the category Asians, like there could be China, Indian, Philippines, etc. Also another way to improve the accuracy is by putting in age groups. Since in every age people grow differently, as for a child they will continue growing, but for an adult they would not grow as much.
