Answer:

Step-by-step explanation:

first multiply 5x24 to get 120. since 45 is 3/4 of 60, multiply 24 by .75 to get 18. Then add 18 to 120 to get 138. i hope this helps you!

In a particular region there is a uniform current density of 18 a/m2 in the positive z direction. what is the value of line inte
Ugo [173]
By Stokes' theorem, the integral is 0. If R is the triangular region bounded by the given line segments composing the curve C, then

\displaystyle\int_{\partial R}\mathbf b\cdot\mathrm d\mathbf s=\iint_R\nabla\times\mathrm d\mathbf r

where \nabla\times F=\mathrm{curl}(0,0,18)=0.

Just to verify this, we can parameterize the path by

C=C_1\cup C_2\cup C_3
\begin{cases}C_1:=\{(4d,3dt,0)~|~0\le t\le1\}\\C_2:=\{(4d(1-t),3d(1-t),0)~|~0\le t\le1\}\\C_3:=\{(4dt,0,0)~|~0\le t\le1\}\end{cases}

\displaystyle\int_C\mathbf b\cdot\mathrm d\mathbf s
=\displaystyle\int_0^1(0,0,18)\cdot(0,3d,0)\,\mathrm dt+\int_0^1(0,0,18)\cdot(-4d,-3d,0)\,\mathrm dt+\int_0^1(0,0,18)\cdot(4d,0,0)\,\mathrm dt
=0+0+0=0

Brayden tosses a coin 500 times. Of those 500 times, he observes heads a total of 416 times. Calculations show that the probabil
elena-14-01-66 [18.8K]

Answer: The probability of this ocurring by chance is less than 0.01.

The meaning of the significance level is that it tells that there is difference of 1% level when there is no actual difference.

Step-by-step explanation:

Since we have given that

Number of times a coin tossed = 500

Number of times head occurs = 416

So, our Z-score would be

Z_\alpha =\dfrac{416}{500}=0.832

So, At significance level of 0.01, p-value of Z-score is .202704.

and p-value < 0.01, i.e. 0.202704<0.832.

Hence, the probability of this ocurring by chance is less than 0.01.

The meaning of the significance level is that it tells that there is difference of 1% level when there is no actual difference.

weeeeeb [17]

Answer:

r=14 in

Step-by-step explanation:

The volume of a cylinder is given by:

v = \pi \times  {r}^{2}  \times h

So,

r =  \sqrt{ \frac{v}{\pi \times h} }  =  \sqrt{ \frac{196 \times \pi}{\pi \times 1} }  =  \sqrt{196}  = 14
