Assume the random variable X is normally distributed with mean mu equals 50 and standard deviation sigma equals 7 . Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded. Upper P left parenthesis 35 less than Upper X less than 65 right parenthesis P (35 < X <65)

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.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
