1. Measurements are collected from 100 subjects from each of two sources. The data
yield the following frequency histograms. The number above each rectangle is its height.
1-10. What did they do? For the following reports about
statistical studies, identify the following items (if possible).
If you can't tell, then say sothis often happens when we
read about a survey.
a) The population
b) The population parameter o
Math 3 315: Expanding Logarithmic Expressions
Now that we have a good understanding of what logarithms are, this week we are going to focus on
some properties of logarithms. Youve already learned two important properties:
log a (1) = 0
log a (a )
AG505: Building Polynomials
Today, we are going to investigate the inner workings of polynomial functions. All of the
polynomials you have seen to date have been written as the sum of different degree terms with
varying coefficients, like a( x ) =
AG501 Special Cubics (2-3 Ext 1)
Our primary tool for factoring cubic expressions is grouping, but there are two special
expressions that require another technique and, thankfully, are easy to spot. These are the sum
or difference of cubes
AG405: Rational Exponents
All of the properties that we learned on AG401 apply to every exponential expression, but so far
we have only simplified expressions with integer exponents. It is possible to have rational
exponents (fractions), and youve
AG401: Properties of Exponents
Our starting point for this unit will be to review properties of exponents. At the start, we must
establish our vocabulary the base is the constant or variable being multiplied, and the
exponent is the number of time
Math 3 501: Factoring by Grouping
We are going to begin our discussion of factoring higher-order polynomials with the grouping
method. Hopefully this is review for some of you, or you have at least seen grouping in action
before. It is very easy,
5-1 Practice C
1. A Yield sign is an equilateral triangle. Draw an equilateral triangle with side
length l in a coordinate plane so that one side is centered at the origin and falls
along the x-axis. Determine the coordinates of each vertex in ter
Math 3 502: Factoring by ac Method
The ac method of factoring is primarily used for factoring quadratic expressions where a, or the
coefficient of the second-degree term, is not equal to 1. Since quadratics dont really count as
Math 3 209: Circles Test Review
1. What is the equation of a circle with center at the origin and radius of 6.5?
2. At how many points do the circles with equations x 2 + y 2 = 49 and x 2 + ( y 5) 2 = 9
3. If a line with equation y = 2x
Math 3 208: Systems of Circles
Essential Question: How can we solve a system of equations that involves a circle?
Earlier this year we discussed solving systems of linear equations, such as the system y = 2 x 8 .
y = x + 5
Math 3 205: Tangent Lines
Essential Question: How can we write the equation of a line that is tangent to a circle at a given point?
(A) Todays objective requires the use of linear functions (because tangent lines are lines), so let
Math 3 – 204: Circle Equation given Center and Point
Quick lesson to start today… probably should have been incorporated into last week, but oh well.
How do you determine the equation of a circle if you know the center and a point on the
Math 3 203: Escape!
Tonight, with the stress of Engsbergs quiz hanging over you, sleep comes slower than usual.
Eventually, after much tossing and turning, you fall into a fitful rest. When you awake, you are
startled to find yourself curled up on
Math 3 202: Completing the Square
Perfect square an integer that is the product of a different integer with itself. Example: 64 is a perfect
square because it is equal to 8 times 8.
We will need to understand the definition of a perfect square bec
Math 3 308: Solving Exponential Equations Part 1
One area we have not covered yet in our review of exponential functions is solving exponential
equations. Understanding how to solve exponential equations can help you later in life if you plan to
Math 3 303: Rational Exponents
All of the properties that we learned on 301 apply to every exponential expression, but so far we
have only simplified expressions with integer exponents. It is possible to have rational exponents
(fractions), and yo
Math 3 301: Review of Exponential Properties
Weve spent the last month discussing polynomial functions, in which the variable was raised to an
exponent. In the next unit, we will start by reviewing exponential functions, where the variable is
Math 3 223: Unit 2 Test 2 Review
(1) How many points do the circle x 2 + y 2 = 49 and the line y = x 10 have in common?
(2) What is the standard form of the equation of a circle with center (4, 7) and radius
(3) What is the general form of the ell
Math 3 201: Circle Equations
Unit 2 covers an algebraic look at a topic called conic sections. These are the shapes that you can
make by intersecting a cone with a plane. The picture below shows the four shapes we are going to
be discussing in thi

Recent weather conditions have caused a dramatic increase in the insect population of the
Okefenokee Swamp area. The insects are annoying to people and animals and health officials
Math 3 121: Vertex-Edge Graphs
MM3A7. Students will understand and apply matrix representations of vertex-edge graphs.
A vertex-edge graph is a collection of points (vertices) and line segments (edges) arranged to
portray how information is connec
Math 3 119: Linear Programming
MM3A6. Students will solve linear programming problems in two variables.
Now that we understand the concepts of graphing inequalities, we can move forward to linear
programming. Linear programming is the process of m
