In a normal distribution, what percent of the values lie above the mean?

1 answer:

5 0

In statistics, the 68–95–99.7 rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within a band around the mean in a normal distribution with a width of two, four and six standard deviations, respectively; more accurately, 68.27%, 95.45% and 99.73% of the values lie .

Dividing the volume by the base area, you find the height to be ...
$\frac{x^{4}+4x^{3}+3x^{2}+8x+4}{x^{3}+3x^{2}+8}=x+1-\frac{4}{x^{3}+3x^{2}+8}$

The height of the prism is $x+1-\frac{4}{x^{3}+3x^{2}+8}$

Find the surface area of the cylinder in terms of π. 8 cm diameter and 17 cm height

JulsSmile [24]

Answer:
168pi cm2

Explanation:
SA = 2pi(r^2) + 2pi(r)h
diameter is 8 cm so radius is 4 cm
SA = 2pi(4^2) + 2pi(4)17
SA = 32pi + 136pi
SA = 168pi cm2
