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.

The nanotechnology is as new science, to scale nanometric

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

Is there any normative that regulates the use of silver nanoparticles?

fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

Tarell

what is the actual application of fullerenes nowadays?

Damian

That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

Tarell

what is the Synthesis, properties,and applications of carbon nano chemistry

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

Do you know which machine is used to that process?
