Answer:
what method exactly r u using ????
If all 25 questions are different,
When order of selection counts:
P(25,7)
=25!/(25-7)!
=15511210043330985984000000/6402373705728000
=2422728000
When order of selection does not count count:
C(25,7)
=25!/(7!*(25-7)!)
=15511210043330985984000000/(6402373705728000*5040)
=480700
Step-by-step explanation:
It is parallel to the third side and has a length equal to half the length of the third side.
so
x= 34/2= 17
x= 17
Answer:
because x is the middle integer of three consecutive integers
=> The remaining 2 numbers respectively are x - 1 and x + 1
=> the sum of these three integers is
x - 1 + x + x + 1 = 3x
Answer:
The area of the shaded region is ![5.86\ cm^{2}](https://tex.z-dn.net/?f=5.86%5C%20cm%5E%7B2%7D)
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the rectangle minus the area of the circle
The rectangle is a square
so
![A=b^{2} -\pi r^{2}](https://tex.z-dn.net/?f=A%3Db%5E%7B2%7D%20-%5Cpi%20r%5E%7B2%7D)
we have
![b=3\ cm](https://tex.z-dn.net/?f=b%3D3%5C%20cm)
![r=1\ cm](https://tex.z-dn.net/?f=r%3D1%5C%20cm)
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute the values
![A=3^{2} -(3.14)(1)^{2}](https://tex.z-dn.net/?f=A%3D3%5E%7B2%7D%20-%283.14%29%281%29%5E%7B2%7D)
![A=5.86\ cm^{2}](https://tex.z-dn.net/?f=A%3D5.86%5C%20cm%5E%7B2%7D)
