Assuming the sequence goes on like this 11,-33,99,-297,891,...,
its general formula is a_n=-11\cdot(-1)^n\cdot3^{n-1}

So, the 9th term is
a_9=-11\cdot(-1)^9\cdot3^{9-1}=-11\cdot(-1)\cdot6561=72171

A company uses a combination of three components- A, B and C to create three different drone designs. The first design Glider us
FrozenT [24]

Answer:

Consider the following calculations

Step-by-step explanation:

Since 1 Blimp uses 2 components of B and C each

=> choosing 2 components of B(remaining after using in other prototypes) for 1st model= 22C2

choosing 2 components of B(remaining after using in other prototypes) for 2nd model= 21C2

choosing 2 components of B(remaining after using in other prototypes) for 3rd model= 20C2

choosing 2 components of B(remaining after using in other prototypes) for 4th model= 19C2

choosing 2 components of B(remaining after using in other prototypes) for 5th model= 18C2

and choosing 2 components of C(remaining after using in other prototypes) = 24C2

Similarly for C

P(5 prototypes of Blimp created)=[(22C2 / 25C2 )*(24C2 / 25C2 )] + [(21C2 / 25C2 )*(23C2 / 25C2 )]+[(20C2 / 25C2 )*(22C2 / 25C2 )]+[(19C2 / 25C2 )*(21C2 / 25C2 )]+[(18C2 / 25C2 )*(20C2 / 25C2 )]
