Answer:

CI  = ( 36,6  ;  41,4 )

Step-by-step explanation:

CI = 99,9  %       α = 0,1 %      α = 0,001

We find z scre for α = 0,001 in z -table

z(s) = - 3,08

CI =  μ₀  ±  MOE          where    μ₀  = 39 min  and   MOE = z(s) * σ/√n

CI = 39  ±   3,08 * 4,8 / √37

CI = 39  ±   2,4315

CI  = ( 36,6  ;  41,4 )

kkurt [141]

Answer:

Option D is correct.

a_3 = \frac{-1}{2}

Step-by-step explanation:

The sequence is in the form of :

a_1, a_2, a_3, a_4, .......

where

a_1 represents the First term.

a_2 represents the Second term.

a_3 represents the Third term.

a_4 represents the Fourth term and so on.....

we have to calculate the a_3 in the given sequence:

Given the sequence:  -4 , -2, -\frac{1}{2} , -\frac{1}{4}, ......    

a_3 = \frac{-1}{2}

Therefore, the third term a_3 = \frac{-1}{2}
