Answer:
The percentage of the bag that should have popped 96 kernels or more is 2.1%.
Step-by-step explanation:
The random variable <em>X</em> can be defined as the number of popcorn kernels that popped out of a mini bag.
The mean is, <em>μ</em> = 72 and the standard deviation is, <em>σ</em> = 12.
Assume that the population of the number of popcorn kernels that popped out of a mini bag follows a Normal distribution.
Compute the probability that a bag popped 96 kernels or more as follows:
Apply continuity correction:
*Use a <em>z</em>-table.
The probability that a bag popped 96 kernels or more is 0.021.
The percentage is, 0.021 × 100 = 2.1%.
Thus, the percentage of the bag that should have popped 96 kernels or more is 2.1%.
1. area of a pentagon when 1 side is x is 
so if perimiter is 100 then one side is 100/5 or 20
area will be
≈<span>688.2 square yards
2. area of a hexagon when 1 side is length x is
so if permiter is 100 then length of one side is 100/6 or about 16.666666666666
the area will be
≈721.7 square yards
3. area of a regular octagon with side lenghts x is
so if 8 sides then side length of each is 100/8 or 12.5
area will be
≈754.4 square yards
octagon wil have most space
you can tell because the more sides it has, the more it gets to a circle and the more area it encloses with a given perimiter
