Give the first five terms of the sequence <br> an=2n2+2

Eddi Din [679]

Answer:

The answer to your question is 3, 9, 19, 33, 51

Step-by-step explanation:

Sequence an = 2n² + 1

1st term a₁ = 2(1)² + 1 = 2(1) + 1 = 2 + 1 = 3

2nd term a₂ = 2(2)² + 1 = 2(2)² + 1 = 2(4) + 1 = 8 + 1 = 9

3rd term a₃ = 2(3)² + 1 = 2(3)² + 1 = 2(9) + 1 = 18 + 1 = 19

4rd term a₄ = 2(4)² + 1 = 2(4)² + 1 = 2(16) + 1 = 32 + 1 = 33

5th term a₅ = 2(5)² + 1 = 2(5)² + 1 = 2(25) + 1 = 50 + 1 = 51

A marketing executive is studying Internet habits of married men and women during the 8am – 10pm time period on weekends ("prime

jolli1 [7]

Answer: Our required probability is 0.18.

Step-by-step explanation:

Since we have given that

Probability that husband is on the internet = 10% = 0.10

Probability that husband is not on the internet = 1-0.10 = 0.9

Probability that wife is on internet given that husband is on internet = 40% = 0.40

Probability that wife is on internet given that husband is not on internet = 20% = 0.20

Probability that wife is on internet is given by

$0.1\times 0.4+0.9\times 0.2\\\\=0.04+0.18\\\\=0.22$

So, Probability that the husband is also on internet given that wife is on internet is given by

$\dfrac{P(\text{wife and husband both on internet)}}{P(wife\ on \ internet)}\\\\=\dfrac{0.4\times 0.1}{0.22}\\\\=\dfrac{0.04}{0.22}\\\\=0.18$

Hence, our required probability is 0.18.
