Variables stand in the place of unknown numbers. For example, in the following equation, one number is unknown: 2+x=5. The x takes the place of the number that is unknown.

What number is represented by the letter p in algebra?

In Algebra there are constants and variables. 'p' is a variable which means that its value can change with reference to the equation it is present in. In Physics, 'p' represents momentum.


Where will you use algebra?

YOU CAN USE ALGEBRA FOR A LOT OF THING. THE LETTERS JUST REPLACE NUMBERS THAT YOU DO NOT KNOW. SAY YOU DID 2P+5N( TAKE P=5 AND N=8) YOU WILL DO 2X5=10 AND 5X8=40, SO YOUR ANSWERS 50.


What is n worth in maths?

Ah ha! In algebra, a letter stands for an unknown value! Some of the most common letters used in algebra are: x, y, n, and p. Some might say 'n' is an uNknown number! haha


How is poisson distribution related to binomial distribution?

If X and Y are i.i.d Poisson variables with lambda1 and lambda2 then, P (X = x | X + Y = n) ~ Bin(n, p) where p = lambda1 / lambda1 + lambda2


Can you divide pointer variables?

No, but if you really want that, use type-cast, for example:printf ("main=%p=5*%lx\n", main, ((long)main)/5);Of course it is good for nothing at all.


Why do you use p and q in math?

You could be learning algebra so the letter P and Q could be there filling in for another number. You can also use other letters.

How do you multiply negatives?

P= positive N=negative P x N = N N x P = N P x P = P N x N = P Hope that helps!?!?!


Suppose that x is binomially distributed with size n and probability p of success what is the probability that x is greater than or equal to 1?

We have to use the expression P(X=x) = nCx px (1--p)(n--x) Here n = n and p=p and x = 1 or x>1 P(X>/=1) = 1 -- P(X</=1) So, P(X<=1) = P(X=0) + P(X=1) This gives nC0 p0 (1--p)(n-0)+ nC1 p1 (1--p)(n--1) ie (1--p)n + n p (1--p)(n--1)
