Multiply the "something" by 7 then divide by 100. As a shortcut, multiply by 0.07 .

### When graphing the function (x+6)/(x-7) I'm getting a vertical line showing up on the graph connecting the two curves that shouldn't be there. do I have something turned on that shouldn't be?

The vertical line is called an asymptote, it is not connecting the graph, it means that the function goes to infinity as the function nears the line. In this case the graph goes to infinity and negative infinity as the x nears 7. This is because the function becomes undefined at x = 7 , plug 7 into x and we get 1/0, dividing by zero is undefined. Thus, the calculator puts the vertical asymptote in the graph to symbolize the action of the function nearing infinity.

### How do I find what the percentage is . . . the amount is 4,117,484 out of a total amount of 163,715,657. I usually divide the amount by the total but when I use a calculator to check (by multiplication)...

100*4117484/163715657 gives me about 2.5%. Since you didn't specify the calculator your're using, I can't give you the exact keystroke sequence, but on a typical algebraic calculator it would be something like 1 0 0 * 4 1 1 7 4 8 4 / 1 6 3 7 1 5 6 5 7 =

On an RPN or RPL calculator, it would be
1 0 0 ENTER 4 1 1 7 4 8 4 * 1 6 3 7 1 5 6 5 7 /

### I used my calculator for years.When I lost my job 3 yrs ago, I stopped using it. How do I calculate a monthly payment for \$100,000 at 7% interest rate over 360 months?

if what you are saying is that you have to calculate 7% monthly from 100 \$ this means exactly \$7 for each month ..so you have to multiply 7 for one month with 360 months and the result will be \$2520 for all 360 ...unless it has some penalties to be calculated or something like that ..If the problem that you describe is accurate this is the answer..

### How to use binomial in calculator

The binomial probability distribution is defined as
P(r;p;n) =(nCr)(p^r)*(1-p)^(n-r), where n is the number of trials, p the probability of success, and r the expected result.

Let n=20, r=7, p=0.15 ( I do not know wether this exemple has any meaning in the context of your problem, but you have to enter values that mean something to you.) I am only showing you the key strokes

To enter 20C7 you press 20 [SHIFT][nCr]7 ;
To enter 0.15 to the power 7 you type 0.15[X to ] 7 the key is between
[x²] and [log]

To enter (1-0.15) to power 20-7, you type 0.85 [X to] 13
With [*] standing for multiplication key , and [X to] the raise to power key, the exemple above can be entered as

( 20 [SHIFT][nCr] 7) [*] ( 0.15 [X to] 7 ) [*] ( 0.85 [X to] 13 ) [=]

Here is a screen capture to show you what it looks like. However on this calculator the combination 20 [SHIFT][nCr] 7 is represented as nCr(20,7).

### Binomial function

Hello,

The binomial probability distribution is defined as
P(r;p;n) =(nCr)(p^r)*(1-p)^(n-r)
where n is the number of trials, p the probability of success, and r the expected result.

Let n=20, r=7, p=0.15 ( I do not know wether this exemple has any meaning in the context of your problem, but you have to enter values that mean something to you. I am only showing you the key strokes

To enter 20C7 you press 20 [SHIFT][nCr]7 ;
To enter 0.15 to the power 7 you type 0.15[X to ] 7 the key is between
[x²] and [log]

To enter (1-0.15) to power 20-7, you type 0.85 [X to] 13
With [*] standing for multiplication key , and [X to] the raise to power key, the exemple above can be entered as

( 20 [SHIFT][nCr] 7) [*] ( 0.15 [X to] 7 ) [*] ( 0.85 [X to] 13 ) [=]

Here is a screen capture to show you what it looks like. However on this calculator the combination 20 [SHIFT][nCr] 7 is represented as nCr(20,7).

Hope it helps

### Comma key on TI-84 Plus Siver Edition calculator.

The comma key on the TI 84 SE is above the 7 key, and it is just left of (, right of x squared, and below SIN. thats where the "," key is. If you're asking something else, please clearify. My understanding is that you don't know where the comma key is.
