Write the following numbers in decimal form. (note: some of these numbers have been rounded.)
the wavelength of light used in optic fibers is 1.55 × 10^−6 m.

So wavelength in decimal can be written as 0.00000155 m                

Step-by-step explanation:

We have given wavelength of light used in optic fibers is

We have to convert this wavelength in decimal form

We know that can be written as

So

So wavelength in decimal can be written as 0.00000155 m

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
