What is the explicit formula for this geometric sequence with recursive formula
Nonamiya [84]

C

generate the first few terms using the recursive formula

a_{2} = - 7 × \frac{1}{3} = - \frac{7}{3}

a_{3} = - \frac{7}{3} × \frac{1}{3} = - \frac{7}{9}

a_{4} = - \frac{7}{9} × \frac{1}{3} = - \frac{7}{27}

r = a_{2} / a_{1} = \frac{1}{3}


the n th term formula (explicit ) for a geometric sequence is

a_{n} = a_{1}r^{n-1} = - 7(\frac{1}{3})^(n - 1)

Apple launches an ad campaign for iPhone 12. Managers want to know what is the % of social media mentions that have positive rea
Orlov [11]

Answer:

social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%

Sample size 'n' = 625

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given data Apple launches an ad campaign for iPhone 12

Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign

probability of positive reactions p = 1/2

Probability of negative reactions q = 1-p = 1/2

we know that \sqrt{p(1-p}\leq \frac{1}{2}

<u><em>Step(ii):</em></u>-

Given margin of error  = 2 % =0.02

The margin of error is determined by

          M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }

         0.02 = \frac{\frac{1}{2}  }{\sqrt{n} }

        \sqrt{n} =\frac{1}{2 X0.02}

        √n = 25

squaring on both sides, we get

       n = 625
