2.3) Give the constant ratio

2.4) Write the rule for the pattern in the form Tn =??​

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

answer: .64

step-by-step explanation

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

according to egenuity the answer is
