Answer:
3x+2
Step-by-step explanation:
The polygon is regular ,<em> </em>so all the sides would be equal.
Thus all sides measure same as <u>3x</u><u>+</u><u>2</u>
Answer:
21, 42, 63, 84
Step-by-step explanation:
3x7=21
Because of this all multiples of 21 will be common multiples of 3 and 7
Answer:y=16
Step-by-step explanation:
Answer:
The underlying probability distribution can't be determined with certainty in this case from the given data, but if we have to take one it would be most preferably the 'Normal Distribution'.
Step-by-step explanation:
The distribution is most probably 'Normal Distribution' as we know that it is the most general and common distribution of all and from the central limit theorem if there is a large sample from any probability distribution with finite mean and variance, the sample mean approaches a suitable normal distribution and for most of the distributions when the parameters tend to a certain value or may be that is ∞ , the resulting distribution tends to a suitable normal distribution , but the underlying probability distribution can't be determined with certainty in this case from the given data.
Answer:
![59.19 ft^2](https://tex.z-dn.net/?f=59.19%20ft%5E2)
Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
we have
![r=7.2\ ft](https://tex.z-dn.net/?f=r%3D7.2%5C%20ft)
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![A=(3.14)(7.2)^{2}](https://tex.z-dn.net/?f=A%3D%283.14%29%287.2%29%5E%7B2%7D)
![A=162.78\ ft^2](https://tex.z-dn.net/?f=A%3D162.78%5C%20ft%5E2)
step 2
we know that
The area of a circle subtends a central angle of 2π radians
so
using proportion
Find out the area of a sector with a central angle of 8 π/11 radians
![\frac{162.78}{2\pi }\frac{ft^2}{rad} =\frac{x}{(8\pi/11)}\frac{ft^2}{rad} \\\\x=162.78(8/11)/2\\\\x=59.19\ ft^2](https://tex.z-dn.net/?f=%5Cfrac%7B162.78%7D%7B2%5Cpi%20%7D%5Cfrac%7Bft%5E2%7D%7Brad%7D%20%3D%5Cfrac%7Bx%7D%7B%288%5Cpi%2F11%29%7D%5Cfrac%7Bft%5E2%7D%7Brad%7D%20%5C%5C%5C%5Cx%3D162.78%288%2F11%29%2F2%5C%5C%5C%5Cx%3D59.19%5C%20ft%5E2)
