Answer:

1.625

Step-by-step explanation:

First we need to find the mean of this data set

29+32+33+28+30+30+29+33=244

Then we divide 244 by the amount of numbers in the set

244/8=30.5

Then we need to find the deviation of each number

29 | 32 | 33 | 28 | 30 | 30 | 29 | 33

1.5 | 1.5 | 2.5 | 2.5 | 0.5 | 0.5 | 1.5 | 2.5

Then we take the mean from this set of data

1.5+1.5+2.5+2.5+0.5+0.5+1.5+2.5=13

Then divide

13/8=1.625

I hope this helps :)

Evaluate the surface integral. S x2z2 dS S is the part of the cone z2 = x2 + y2 that lies between the planes z = 4 and z = 5

sammy [17]

The surface $S$ can be parameterized in cylindrical coordinates using

$\mathbf r(u,v)=(x(u,v),y(u,v),z(u,v))=(u\cos v,u\sin v,u)$

where $4\le u\le5$ and $0\le v\le2\pi$ . The surface integral is then equivalent to

$\displaystyle\iint_Sx^2z^2\,\mathrm dS=\int_{v=0}^{v=2\pi}\int_{u=4}^{u=5}(u\cos v)^2u^2\left\|\mathbf r_u\times\mathbf r_v\right\|\,\mathrm du\,\mathrm dv$
$=\displaystyle\sqrt2\int_{v=0}^{v=2\pi}\int_{u=4}^{u=5}u^5\cos^2v\,\mathrm du\,\mathrm dv$
$=\dfrac{3843\pi}{\sqrt2}$
