How many terms are there in the expression 3x2 + 2x - 4?
a: 1
b: 2
c: 3
d: 4

The correct option is C.

Step-by-step explanation:

The given expression is

Definition of term: A term is either a single number or variable, or product of numbers and variables. The signs  +, −, / and = are used to separate the terms.

In the given expression the variables are separated by + and −.

The given expression has three terms .

Therefore the correct option is C.

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

i am thinking c. sorry if im wrong .
