Given: V=(1/3)Bh, where B is the area of the base and height.

A pyramid has a rectangular base. Find the volume if the length and width of the base and and the height are three consecutive odd integers and x is the largest integer.

The answer I came up with:
(x^3 - 3x^2 + 2x)/3

If it's wrong can someone show me how to figure out this equation?

One of my students does not have L1 when you go into STAT Edit List. It begins with L2, L3, etc. I've reset his RAM and that did not do anything. Any ideas how to rename that first column back to to L1?

Thanks

loan (based on a 30-year mortgage with a 10% down payment).
Interest Rate 7.0% 7.5% 8.0% 8.5% >8.5%
Probability 0.12 0.23 .24 .35 0.06

2. If a bank is selected at random from this distribution, what is the chance that the interest rate charged on a home loan will exceed 8.0%?

3.The employees of a company were surveyed on questions regarding their educational background and marital status. Of the 600 employees, 400 had college degrees, 100 were single, and 60 were single college graduates. The probability that an employee of the company is single or has a college degree is

4.The probability that house sales will increase in the next 6 months is estimated to be 0.25. The probability that the interest rates on housing loans will go up in the same period is estimated to be 0.74. The probability that house sales or interest rates will go up during the next 6 months is estimated to be 0.89.

How do you do step (greatest integer/least integer) functions with theta or with transformations? Ex:
The limit as x goes to 3+ of the greatest integer [θ]/θ. I know the answer is 1 but I'm not sure how.
OR: the limit as x goes to 4+ of x- the greatest integer x:
(x-[x])

9^3/7 * 3^1/7=?

In other words 9 to the power of 3/7 multiplied by 3 to the power of 1/7. I think it has something to do with square roots although I am not certain what.

First graph has two arrows.
A line with an open circle at
(-2,2) going left forever horizontal.
another line with close circle at (-2,-2) going right horizontal forever.

second graph is just like the one above except that both start with open circles.

Third graph is strange because it does not have a circle but from that perticular point two arrows come out of it, with out circle or point. At (-2,2) one arrow goes right horizontal forever and the other one from again (-2,2) goes down at an angle hitting the x axis at (-4,0). It kinda looks like
3:40 on a clock. with (-2,2) in the middle.

Fourth graph has same starting point. there are two arrows from (-2,2).One is going down at an angle hitting the x axis at (-3,0). The other arrow is kinda strange because it starts from (-2,2) but then bends to the right alittle at (-1.5,2) then goes up till it hits the y axis at (0,6).

The question that i have is does the limit exist at x= -2

really need your help
