Assuming a normal distribution, approximately 99.7% of the distribution already falls within 3 standard deviations of the mean. You're asking about how much of it falls within 8 standard deviations of the mean, which may as well be 100%.

If you're asking for more precision, it's roughly 99.99999999999987%.

In sunlight, a vertical stick has a height of 4 ft and casts a shadow 2 ft long at the same time that a nearby tree casts a shad
marshall27 [118]
Remark
Make up a proportion that relates the tree and its properties to the stick and its properties.

Givens
Stick height (s_h) = 4
Stick shadow(s_s) = 2
Tree shadow = t_s = 18
Tree height = x

Formula
s_h / s_s = x / t_s

Substitute and solve.
4/2 = x / 18  Cross multiply
4*18 = 2 * x
72 = 2x        Divide by 2
72/2 = x       
x = 36

The height of the tree is 36 feet.
