Answer:

6. 80

7.85

Step-by-step explanation:

If you add all three angles of a triangle it will equal 180, so you just have to subtract the 2 angles you have from 180.

if Ethan Buy 100Tv All the Tv Cost 3,000$,If he sold all his Tv With 1,800$.How Many money will he have than?
jolli1 [7]
I don't know if that is 100 tvs or one 100 inch tv. 

If it is 100 tvs then the person would have 301,800 dollars.
3,000 times 1000 plus 1800 equals= 301,800

If it is one 100 inch tv then the person would have 4,800 dollars
3,000+1800=4800.

According to a National Health Survey, American men’s heights are normally distributed with a mean given by μ=69.7 inches and a
Novay_Z [31]

Answer: 0.206

Step-by-step explanation:

Given that :

Height of American men is normally distributed :

Mean height (μ) = 69.7 inch

Standard deviation (σ) = 2.8 inch

Probability that height of a randomly selected man is more than 72 inches

P(X > 72)

Obtain the standardized score (Zscore):

Zscore = (x - μ) / σ

Zscore = (72 - 69.7) / 2.8

Zscore = 2.3 / 2.8

Zscore = 0.8214285

Zscore = 0.8214

Using the Z probability calculator ;

P(Z > 0.8214) = 0.20571

Probability of selecting a man whose height is more Than 72 is 0.206

Let f = (ax + by + 4z) i + (x + cz) j + (9y + mx) k where a, b,c, and m are constants.

Let \mathcal R be an arbitrary closed region with boundary the surface \mathcal S. By the divergence theorem,

\displaysytle\iint_{\mathcal S}\mathbf f(x,y,z)\cdot\mathrm d\mathbf S=\iiint_{\mathcal R}\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV

We have

\nabla\cdot\mathbf f(x,y,z)=\dfrac{\partial(ax+by+4z)}{\partial x}+\dfrac{\partial(x+cz)}{\partial y}+\dfrac{\partial(9y+mx)}{\partial z}=a

so that the flux satisfies

\displaystyle a\iiint_{\mathcal R}\mathrm dV=0

We're assuming \mathcal R is a closed region, and the integral above is its volume, which must be positive. This means we must have a=0.
