Use the divergence theorem to calculate the surface integral ??s f · ds; that is, calculate the flux of f across s. f(x,y,z = x2
Ymorist [56]
By the divergence theorem, the surface integral given by

\displaystyle\iint_{\partial S}\mathbf F\cdot\mathbf n\,\mathrm dS

(where the integral is computed over the entire boundary of the surface) is equivalent to the triple integral

\displaystyle\iiint_R\nabla\cdot\mathbf F\,\mathrm dV

where V is the volume of the region R bounded by \partial S.

You have

\mathbf F(x,y,z)=x^2y\,\mathbf i+xy^2\,\mathbf j+4xyz\,\mathbf k
\implies \nabla\cdot\mathbf F=\dfrac{\partial}{\partial x}[x^2y]+\dfrac{\partial}{\partial y}[xy^2]+\dfrac{\partial}{\partial z}[4xyz]=8xy

and so the integral reduces to

\displaystyle8\int_{x=0}^{x=5}\int_{y=0}^{y=1}\int_{z=0}^{z=5-x-5y}xy\,\mathrm dz\,\mathrm dy\,\mathrm dx=-\dfrac{250}3

Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with μ=10
Tju [1.3M]

Answer: 0.8238

Step-by-step explanation:

Given : Scores on a certain intelligence test for children between ages 13 and 15 years are approximately normally distributed with \mu=106 and \sigma=15.

Let x denotes the scores on a certain intelligence test for children between ages 13 and 15 years.

Then, the proportion of children aged 13 to 15 years old have scores on this test above 92 will be :-

P(x>92)=1-P(x\leq92)\\\\=1-P(\dfrac{x-\mu}{\sigma}\leq\dfrac{92-106}{15})\\\\=1-P(z\leq })\\\\=1-P(z\leq-0.93)=1-(1-P(z\leq0.93))\ \ [\because\ P(Z\leq -z)=1-P(Z\leq z)]\\\\=P(z\leq0.93)=0.8238\ \ [\text{By using z-value table.}]

Hence, the proportion of children aged 13 to 15 years old have scores on this test above 92 = 0.8238
