# Sequences
Resources
A sequence is an ordered list of numbers. It can be thought of as a function, ƒ(n ), where the argument, n, takes on the natural-number values 1, 2, 3, 4, (or occasionally 0, 1, 2, 3, 4, ). A sequence can follow a regular pattern or an arbitrary one. It may be possible to compute ... |
# In a single roll of a six-sided dice, what is the probability of rolling a three or an even number?
Oct 15, 2017
$\frac{1}{12}$
#### Explanation:
You have 2 events: A & B.
$\textcolor{m a \ge n t a}{A}$: rolling a three
$\textcolor{b l u e}{B}$: rolling an even number
$\Rightarrow P \left(A \mathmr{and} B\right)... |

# Cutting Triangle in Two by a Line through a Point
An interesting non-trivial problem has been posted at the math.stackexchange. An elegant solution was found by Dan Shved, a graduate student at the Moscow Institute of Physics and Technology. Dan's solution is interesting in that it was inspired by the properties of ... |
# Proportional function
Proportional means that if x is changed, then y is changed in the same proportion.
The graph of a proportional function is a straight line passing through the origin (0,0).
For example, if one peice of chocolate costs $2, then two pieces of chocolate cost$4, three pieces cost \$6 and so forth... |

# what is 3x-12=14?
Ok bob, what happens if we add 12 to both sides? Why can we do this?
After that step, what happens if we divide both sides by 3? Why is that allowable? What value do we get for x then?
