Find the maximum rate of change of f(x,y,z=x y/z at the point (2, -3, 5 and the direction in which it occurs. maximum rate of ch
kherson [118]
f(x,y,z)=x+\dfrac yz
\implies \nabla f(x,y,z)=\left(1,\dfrac1z,-\dfrac y{z^2}\right)
\implies \nabla f(2,-3,5)=\left(1,\dfrac15,\dfrac3{25}\right)

The maximum rate of change is then

\|\nabla f(2,-3,5)\|=\dfrac{\sqrt{659}}{25}

which occurs in the direction of \nabla f(2,-3,5) above.

The mean value of 500 homes in a county is $225,000 and the standard deviation is $25,000. approximately how many of the homes i
dusya [7]

240 homes in the county are between $175,000 and $225,000.

The image attached is associated with this question and m in it refers to the mean value which is $225000 here and d refers to the standard deviation which is $25000 here.

Now since m= $225000

and $175000= $225000-$50000= $225000-(2* $25000)= m-2d

Thus, as per the image area covered between m and m-2d=  $225000

and $175000 is (34%+14%)of 500 homes= 68% of 500= 240 homes, is the answer.

A random variable X is said to follow a normal distribution if its parameters are mean and standard deviation. Every other distribution can be reduced to a normal distribution.
