1) Create an integral that gives the exact value for (1^2+2^2+3^2+4^2+...+n^2)/(n^3)

2) Find the limit, as x approaches 5, of (2x/(x-5)) x the integral of [sin(t)]/t dt.
I think this has something to do with as f(a)-f(x)/(a-x)=f'(a) or something like that. I heard that it is 0 or undefined.

3) Evaluate the integral of square root of (b^2-x^2) dx from the interval (b/square root of 2) to b. I need to show the graph and find an exact value without using a calculator.

You don't have to answer all questions but 1 would be nice.

Sixty percent of the student body at UTC is from the state of Tennessee (T), 30% percent are from other states (O), and the remainder are international students (I). Twenty percent of students from Tennessee live in the dormitories, whereas 50% of students from other states live in the dormitories. Finally, 80% of the international students live in the dormitories..

a.What percentage of UTC students live in the dormitories?

b.Given that a student lives in the dormitory, what is the probability that she/he is an international student?

c.Given that a student does not live in the dormitory, what is the probability that she/he is an international student?

In geometry how do you find maximum area if, say, the given perimeter is 36. I'm sure it's really easy I just totally forgot. Thanks!

I understand that you have to multiply both sides by LCD, which is 4, but it seems like my math instructions are leaving out the multiplication by 4 on the left side of the equation.

6 (x+6)
--------- = 4x - 1
4

Rework problem 13 in section 4.1 of your text, involving drawing three cards from a deck of cards. Assume that the deck contains 4 aces, 7 other face cards, and 9 non-face cards, and that you randomly draw 3 cards. A random variable Z is defined to be 3 times the number of aces plus 2 times the number of other face cards drawn.

How many different values are possible for the random variable Z?

PART 2:

Fill in the table below to complete the probability density function. Be certain to list the values of Z in ascending order.

part 1 is 9 and the values are 1-9. i have no idea how to find the prob of 1-9 though

I think someone said that it's 0 but i'm not sure how to get to that. The x, y, and z are constants I believe. Anyways, please solve step by step if anyone knows. Thanks
