Find the third quartile of ages of cars in the lot. This means you will have to find the value such that
$\frac{3}{4}$ , or 75%, of the cars are at most (less than or equal to) that age.

Sketch the graph. Shade the area of interest.

Find the value
$k$ such that
$P(x<k)=0\text{.}\text{75}$ .

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?
