Answer:

a = 2048 × (¼)^n

Step-by-step explanation:

Area after a fold is ¼th of the previous area

One fold: a = 2048 × ¼

Two folds: a = (2048 × ¼) × ¼

= 2048 × (¼)²

Three folds: a = (2048 × (¼)²) × ¼

= 2048 × (¼)³

a = 2048 × (¼)^n

Find the z-score for which 12% of the distribution's area lies between-z and z.
Bezzdna [24]
Since the normal distribution is symmetrical, we only need to consider the distribution for 56% or 0.56, because 6% is half of 12%.
The Z score is 0.15 approximately.
Z score of -0.15 is 1-0.56=0.44 and the difference between 0.56 and 0.44=0.12 which is 12%.
Therefore 12% of the distribution lies between -0.15 and 0.15.
