Answer:

B. $-\frac{7}{10}$ = -.7

Step-by-step explanation:

Replace all occurrences of − − with a single +. Two consecutive minus signs have the same mathematical meaning

$-.75+\frac{2}{5}+.4-\frac{3}{4}$

Find the common denominator.

$\frac{-.75*20}{20} +\frac{2*4}{20} +\frac{.4*20}{20}-\frac{3*5}{20}$

Simplify terms.

$\frac{-15+8+8-15}{20}$

Simplify the numerator.

$\frac{-14}{20}$

Reduce the expression by cancelling the common factors.

$-\frac{7}{10}$

Step-by-step explanation:

A modified box plot does not include the outliers in the whiskers, instead they are points outside of the whiskers

5,25,33,34,34,37,37,40,42,45,45,46,46,49,73

This data has 2 outliers 5 and 73 so we have 2 choices for a modified box plot D or D

The lowest value outside of the outliers is 25 , so C would be the logical choice

D has the lower end of the whisker too close to the outlier

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 = ex

Kamila [148]

$\mathbf f(x,y,z)=e^x\sin y\,\mathbf i+e^x\cos y\,\mathbf j+yz^2\,\mathbf k$

By the divergence theorem, the surface integral can be evaluated by computing the triple integral

$\displaystyle\iint_Sf(x,y,z)\,\mathrm dS=\iiint_V\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV$
$=\displaystyle\iiint_V\left(\dfrac{\mathrm d\mathbf f}{\mathrm dx}+\dfrac{\mathrm d\mathbf f}{\mathrm dy}+\dfrac{\mathrm d\mathbf f}{\mathrm dz}\right)\,\mathrm dV$
$=\displaystyle\int_{x=0}^{x=4}\int_{y=0}^{y=3}\int_{z=0}^{z=4}2yz\,\mathrm dz\,\mathrm dy\,\mathrm dx$
$=72$
