City crime records show that 20% of all crimes are violent, and 80% are nonviolent,
involving theft, forgery, and so on. Ninety percent of violent crimes are reported versus 70%
of nonviolent crimes. If a crime in progress is reported to the police, what is the probability
that the crime is violent?

A cylinder is inscribed in a right circular cone of height 7.5 and radius (at the base) equal to 5. You will be asked to determine the dimensions of such a cylinder which has maximum volume.

a. First, if the radius of such an inscribed cylinder is x, then its height will be (express the cylinder's height as a function of x)

b. Next, give an expression for the volume of the inscribed cylinder in terms of its radius x.

c. Finally, the inscribed cylinder that maximizes its volume will have dimensions:
Height:
Radius:

Please explain and answer each question given using simple words and not math jargon. I need to understand the FACTS in baby-like terms.

(1) Why does the letter y the same thing as writing f(x). In other words, why does y = f(x) and vice-versa?

(2) What is the basic difference the lines y = x and y = - x?

(3) Why do square root answers have a positive and negative result? Sample: sqrt{4} = +2 and -2. Why TWO answers?

(4) What is the most basic difference between the words DOMAIN and RANGE?
