today in math

HW
Kings switches due 11/10
quiz wednesday
HW 9?

Today we had a wonderful hour and a half of math. Caitlin laughed, Lilli danced, keith sang a song about the heartland. Good times were had by all. Except for Camilla who huddled in a corner and cried like the little dark emo she is. But on a more serious note, let's talk mathematics. And imagine I'm tellin you this with an irish brooch.

Normal Table Page 398

This handy little table lists numbers of standard deviations, starting at zero and increasing by 0.1, and their corresponding area within the standard deviation of the mean. This comes in handy when finding percentages of natural functions that are between one and two deviations.

HW 8 Page 400

Using the natural table, we rationalized ways to find answers to questions similar to those we have done earlier in this unit. The main idea was finding percentages of graphs that lay between 1 and 2 deviations.

Back to the Circus page 402.

A circus stunt girl rides her bike towards a wall and would like to know how close she can start stopping while crashing only 5% of the time.

It was fun. Long live math
