According to empirical rule, the area under the normal distribution or "bell-shaped curve", when plotted as a function of the z-parameter can be defined in terms of percentages.
The z-parameter (or z-score) is defined as
where
x = value of random variable,
μ = the mean,
σ = standard deviation,
The total area under the curve = 1.
The curve below shows that within 2 standard deviations from the mean, the total area under the curve is 95% of the total area.
Answer: 95%

Answer:
The solid formed is a cylinder
The total surface area is
Step-by-step explanation:
The given net is made up of a rectangle and two circles.
The total surface area is the area of the rectangle plus the area of the two circles.
This implies that:
The rectangular surface can be folded into the curved surface of a cylinder with the two circles becoming the lid.
