When dealing with a pool of data, the field of study is called statistics. This refers to the study of sample data and how they correlate it with the overall trend of the population. By doing this, they use terms that can best represent the sample data. These three are the most common:

1. Mean - this is the arithmetic average of the data

Mean = (<span>8+41+25+9+22+36+24+13+25+28)/10 = 23.1

2. Mode - this is the most frequent data point that can occur. In this case, the mode is 25 because it occurred twice.

3. Median - this is the middle of the sample data arranging it from least to greatest. In this case: 8, 9, 13, 22, 24, 25, 25, 28, 36, 41. The middle number is 25. Thus, the median is 25.</span>

) Set up a double integral for calculating the flux of F=3xi+yj+zk through the part of the surface z=−5x−2y+2 above the triangle
Fynjy0 [20]

The surface (call it S) is a triangle with vertices at the points

x=0,y=0\implies z=2\implies(0,0,2)

x=0,y=2\implies z=-2\implies(0,2,-2)

x=2,y=0\implies z=-8\implies(2,0,-8)

Parameterize S by

\vec s(u,v)=(1-v)(2,0,-8)+v\bigg((1-u)(0,2,-2)+u(0,0,2)\bigg)=(2-2v,2v-2uv,-8+6v+4uv)

with 0\le u\le1 and 0\le v\le1. Take the normal vector to S to be

\vec s_v\times\vec s_u=(20v,8v,4v)

Then the flux of \vec F across S is

\displaystyle\iint_S\vec F(x,y,z)\cdot\mathrm d\vec S=\int_0^1\int_0^1\vec F(x(u,v),y(u,v),z(u,v))\cdot(\vec s_v\times\vec s_u)\,\mathrm du\,\mathrm dv

=\displaystyle\int_0^1\int_0^1(6-6v,2v-2uv,-8+6v+4uv)\cdot(20v,8v,4v)\,\mathrm du\,\mathrm dv

=\displaystyle8\int_0^1\int_0^1(11v-10v^2)\,\mathrm du\,\mathrm dv=\boxed{\frac{52}3}
