Vitek1552 [10]

Answer: 1) 2, 3, 4, 9, 32, 279, 8896, 2481705, 22077238784

              2) 2,490,924

              3) Neither

<u>Step-by-step explanation:</u>

S_n=S_{n-2}\cdot (S_{n-1}-1)\quad \\\\S_1=2\quad given\\S_2=3\quad given\\S_3=S_1(S_2-1)\quad =2(3-1)\quad =4\\S_4=S_2(S_3-1)\quad =3(4-1)\quad =9\\S_5=S_3(S_4-1)\quad =4(9-1)\quad =32\\S_6=S_4(S_5-1)\quad =9(32-1)\quad =279\\S_7=S_5(S_6-1)\quad =32(279-1)\quad =8,896\\S_8=S_6(S_7-1)\quad =279(8896-1)\quad =2,481,705\\S_9=S_7(S_8-1)\quad =8896(2481705-1)\quad =22,077,238,784

\sum^8_{k=1}S_k\\\\=S_1+S_2+S_3+S_4+S_5+S_6+S_7+S_8\\\\= 2,490,924\\

Neither

Not arithmetic because the difference between each of the terms is not the same.            

                        S₂ - S₁          S₃ - S₂           S₄ - S₃      

                      3 - 2 = 1       4 - 3 = 1          9 - 4 = 5

Not geometric because the ratios between each of the terms is not the same.                

                       \dfrac{S_2}{S_1}=\dfrac{S_3}{S_2}\qquad \rightarrow \dfrac{3}{2}=\dfrac{4}{3}\qquad \rightarrow \text{cross multiply to get}: 9\neq 8

if 7 men and 5 womean have applied for job and 3 applicants are randomly selected from the probability that 2 are men​
barxatty [35]

The  probability that 2 men are selected is 49/144

Probability is the likelihood or chance that an event will occur.

If 7 men and 5 women have applied for job, the total number of people that applied will be 12 people

  • Pr(2 men are selected) = 7/12 * 7/12
  • Pr(2 men are selected) = 49/144

Hence the  probability that 2 men are selected is 49/144

Solve the system of equations below x-2y=3 <br><br> 2y-3y=9
Crank
First you solve 2y-3y=9.
2y - 3y = 9 \\ subtract \: 2y \: and \: 3y \\  - y = 9 \\  divide \: by \:  - 1 \\ y =  - 9
Now that you have y, then you substitute y into x-2y=3 to find X

x - 2( - 9) = 3 \\ multiply \:  - 9 \times  - 2 \\ x + 18 = 3 \\ subtract \: 18 \: on \: both \: sides \\ x =  - 15
Your solution is (-15, -9)
