Probability Practice

I was asked to post the answers to the practice problems from today.  Enjoy:

Oh, yeah: I sent a tweet out earlier about someone's birthday.  He was almost a Leap Year baby.

Calculus Class Today

OK, I found my mistake and it makes for beautiful stuff.

First, here is where we were...

When I cancelled out the square from n, I forgot to carry the n through.  It is below in red.

So, instead of taking out the 1/3, I just broke up the numerator and made three fractions with 3n as the denominator.

Then, I distributed the 2/n back through and simplified.

Since this is a limit at zero, everyone with an n in the denominator goes to zero.

That leaves us with adding the constants.

When we bring back in what we determined about the integral of 2 from earlier, we get...

If you remember, our estimate with the rectangles and trapezoids was 12.75.  Look how close we got to the actual area, using just 4 rectangles or 4 trapezoids.  I wonder how many more rectangles or triangles would shrink that 0.08333... difference?

Analytic Geometry Test # 3

Tomorrow is the Analytic Geometry Test over Parabolas.  Specifically, we are graphing parabolas, detailing their chief characteristics, convert between vertex and standard forms, analyzing transformations, and solving quadratic word problems.

By the way, I wonder where I was when I was Tweeting that stuff Friday while I was not at school...

Analytic Geometry Test # 2

Here are some links for tomorrow's test.

These include the answers to the pages we worked on in class today, as well as a link to some more inequalities.

By the way, I may Tweet out the foreign country that I used to live in, that is, if I can remember...

Analytic Geometry Test Tomorrow

Here is a link to the review quiz we took today, including key.  Good luck.

New Semester

Analytic Geometry is off to a great start.  Thus far, we have worked on exponents, including 0 and negatives, polynomials, and irrational numbers.  Our first test of the semester will be on Thursday, 1/14.  Attached is the link for the extra polynomial practice passed out today.

PS: Mr. Lewis was born near the city of Great Falls.

The End is Near!

On Friday, the two Analytic Geometry classes will take their "Sorta" Final.  Since we took the Milestones, and that accounts for 20 % of our grade, the students who are here Friday will take a test that can replace any of their scores on Tests 5 (Triangles), 6 (Probability), and 7 (Circles).  We have worked on old tests and a study guide the past two days, so hopefully everyone will have something to study.

Below are links to the review and the answers:
