lord [1]

Answer:

2000 USD

Step-by-step explanation:

a. Difference for employee 1: 14000 - 10000 = 4000

b. Difference for employee 2: 11000 - 12000 = -1000

c. Difference for employee 3: 13000 - 11000 = 2000

d. Difference for employee 4: 10000 - 8000 = 2000

e. Difference for employee 5: 12000 - 9000 = 3000

The absolute mean difference of 5 employees is

(4000 - 1000 + 2000 + 2000 + 3000)/5 = 10000/5 = 2000

So the average net increase of each employed in the past month is 2000 USD

Find the jacobian of the transformation. x = u2 + uv, y = uv2
atroni [7]
\mathbf J=\begin{bmatrix}\dfrac{\partial x}{\partial u}&\dfrac{\partial x}{\partial v}\\\\\dfrac{\partial y}{\partial u}&\dfrac{\partial y}{\partial v}\end{bmatrix}=\begin{bmatrix}2u+v&u\\v^2&2uv\end{bmatrix}

The Jacobian has determinant

\det\mathbf J=\begin{vmatrix}2u+v&u\\v^2&2uv\end{vmatrix}=(2u+v)2uv-uv^2=4u^2v+uv^2=uv(4u+v)
