What is the mean of the data set.<br> 82 105 247 119 94 202
Genrish500 [490]
Mean is an average.

In order to find mean we must add up all the numbers and divide by how many numbers there are.

82 + 105 + 247 + 119 + 94 + 202

Adding them together and we get...

849.

We can see that we have 6 numbers.

849/6

849 divided by 6 is...

141.5

That is the mean.

Please leave a rating and a thanks.

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = -f. If it is not, enter NON
GrogVix [38]

We need to have

\dfrac{\partial f}{\partial x}=2x-4y

\dfrac{\partial f}{\partial y}=-4x+10y-5

Integrate the first PDE with respect to x:

\displaystyle\int\frac{\partial f}{\partial x}\,\mathrm dx=\int(2x-4y)\,\mathrm dx\implies f(x,y)=x^2-4xy+g(y)

Differentiate with respect to y to get

\dfrac{\partial f}{\partial y}=-4x+10y-5=-4x+\dfrac{\mathrm dg}{\mathrm dy}\implies\dfrac{\mathrm dg}{\mathrm dy}=10y-5

\implies g(y)=5y^2-5y+C

So we have

f(x,y)=x^2-4xy+5y^2-5y+C

which means F is indeed conservative.
