Chebyshev's inequality states that:
P(X - E(X)| ≥ a) ≤ 1/a^2 * var(X)

Using Chebyshev's inequality, prove the law of large numbers.

I can't figure it out! I keep messing up, I think. Here's what I did, where are my mistakes?:
(15)/(8y)=(21)/[4(y-3)]
15[4(y-3)]=21(8y)
Distribute 4 and 21
15(4y-12)=168y
Distribute 15 now
60y-180=168y
subtract 60y from both sides
-180=108y
Divide both sides by 108
y=1(2/3) or 1.666667

But, then I plug y in, and it's wrong. I can't find the problem

I was trying to divided some numbers by hand (paper and pen) and I couldn't figure out how to do it. I had to do a search online to find out. Has the calculator made us dumb?

I got to 9x2+30x^2y^2+25y^2. Now how do I simplify that? Or is that correct? the answer choices are like 9x^2+25y^2, 9x^2+15xy+25y^2, plus two others. Thanks a lot.

I'm don't know how to solve this problem. Could someone assist me?

A manufacturing produces bolts of a fabric with a fixed width. The quantity q of this fabric (measured in yards) that is sold is a function of the selling price p (in dollars per yard), so we can write q=f(p). Then the total revenue earned with selling price is R(p)=pf(p).

a. What does it mean to say that f(20)=10,000 and f ' (20) = -350?

b. Assuming the values in part a, find R ' (20) and interpret your answer.

I'm really confused as to how to approach this problem. I know the product and quotient rules, but I'm still confused. Could someone please help me? Thanks!

It is estimated that the peron income is rising in Miami metropolitan area. In July 2001, the population of this area was 3,354,000 and increasing at roughly 45,000 per year. The average annual income was $21,107 per capita, and this average was increasing about $1900 per year (well above the national average of about $660). Use the Product Rule and these figures to estimate the rate at which total personal income was rising in Miami in July 2001. Explain the meaning of each term in the Product Rule.
