The student will analyze data following a normal distribution.

Given

The life of Sunshine CD players is normally distributed with a mean of 4.1 years and a standard deviation of 1.3 years. A CD player is guaranteed for 3 years. We are interested in the length of time a CD player lasts.

Normal distribution

Define the Random Variable
$X$ in words.
$X=$

$X$ ~

Find the probability that a CD player will break down during the guarantee period.

Sketch the situation. Label and scale the axes. Shade the region corresponding to the probability.

$P(0<x<\text{\_\_\_\_\_\_\_\_\_})=\text{\_\_\_\_\_\_\_\_\_}$ (Use zero (0) for the minimum value of x.)

$\mathrm{3,0}\text{.}\text{1979}$

Find the probability that a CD player will last between 2.8 and 6 years.

Sketch the situation. Label and scale the axes. Shade the region corresponding to the probability.

if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION

Anam

analytical skills graphene is prepared to kill any type viruses .

Any one who tell me about Preparation and application of Nanomaterial for drug Delivery

The nanotechnology is as new science, to scale nanometric

brayan

nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
