To find the coordinates of the centroid of the tetrahedron whose vertices are (x 1 , y 1 , z 1 ), (x 2 , y 2 , z2 ), (x 3 , y 3 , z3 ) and (x 4 , y 4 , z4 ).
Let A( x 1, y 1, z 1), B( x 2, y 2, z 2), C( x 3, y 3, z 3), D( x 4, y 4, z 4) be the vertices of tetrahedron ABCD. If G 1 is the centroid of ?BCD, then its coordinates are
Since G( x, y, z), the centroid of tetrahedron ABCD divides the line AG 1 in the ratio 3 : 1.

Similarly,
Hence the centroid is

Gravity. Put the two concepts together and the long answer will come to you.
It is function of the density of the three metals. The density of iron is less than that of mercury, but the density of gold is greater. Density of iron: 7.86 g/cm3 Density of mercury: 13.53 g/cm3 Density of gold: 19.3 g/cm3 Anything more dense than a liquid will sink in that liquid, and anything less dense will float. For comparison, the density of water is only 1 g/cm3, so all three would sink in a pool of water. Styrofoam for instance is less dense than water and so it floats in water.
Its density. Density is mass per unit volume.
This is the determination of the specific density (the ratio liquid density/water density).

the centroid the point at which one can balance the triangle
the point shared by a triangle's medians the point at which one can balance the triangle
Archimedes showed that the point where the medians are concurrent is the center of gravity of a triangular shape of uniform thickness and density.
2 apex fill-in-the-blank Q's: 1) The center of gravity of a trianglular solid with uniform thickness and density is at the intersection of the medians of the triangle. 2) The center of gravity of a triangular solid with uniform thickness and density is the centroid. medians the point at which one can balance the triangle. and the point shared by a triangle's medians. medians centroid Medians i got centriod?
No. f is a letter of the Roman alphabet. It cannot be a probability density function.
What is "propability"?
what is density curve
The probability density function of a random variable can be either chosen from a group of widely used probability density functions (e.g.: normal, uniform, exponential), based on theoretical arguments, or estimated from the data (if you are observing data generated by a specific density function). More material on density functions can be found by following the links below.
