Last class, we learned how you can use the ideal normal distribution to determine the % of
individuals that fall within a certain range of values. We were only able to do this, though, if
the values were exactly 1, 2 or 3 standard devia

Distributions
Sometimes distribution refers to the shape of the graph of the data.
There are different kinds of distributions:
uniform

The point of learning to use. systems of inequalities is to determine the optimal solution
given a number of constraints. In order to translate a story or situation into a system, you
must:

6.1 Graphing Linear Inequalities in Two Variables
An inequality is a statement that involves a greater than or less than symbol.
Ex.
A linear inequality in two variables is an inequality statement that describes the relationship
between one variable

y = x2 ;
y = (t 5) ;
y = 2 x 2 50 ;
y = t 2 + 3t 1 ;

y = 2 ( x 5) + 7
Some example of non-quadratic functions:

After you have modeled the problem with a system of inequalities and an objective function,
you can graph the solution region; however, drawing the graph alone doesnt tell you which of

Using the graph:
Is (3, 4) a solution to this system?

6.2 Graphing Systems of Linear Inequalities
A system of inequalities just means there are two or more inequalities.
The solution to a system is the set of all the points (x, y) that make all the inequalities true.

No survey can ever give perfect information about the entire population. The best you can do
is to select a representative sample of the population in the hopes that the smaller group has
a similar composition and variation
