Since the NHL started having the “Winter Classic”, an outdoor hockey game that takes place on New Year’s Day, many people have become more interested in watching hockey regularly. Mrs. DaSilva has always been a hockey fan and has decided to organize a group to go visit the Hockey Hall of Fame in Toronto, Canada.
Unfortunately for Mrs. DaSilva, who doesn’t like the cold very much, it is likely quite cold in Toronto. She has asked her math classes to find the average temperature in Toronto.
The average daily temperatures (in Fahrenheit) in Toronto for the previous two weeks are: +1, -1, 0, -2, +4, -1, -1, -9, -6, -9, -12, -2, 0, and +3.
1. What is the range of the data?
2. What is the median temperature?
3. What is the mean temperature?
4. What is the mode temperature?
5. How would the mean change if the next day’s temperature of +7 was included in the data?
BONUS: Suppose you were told that the average temperature in Toronto for one week in December was -1 degree Fahrenheit. You could read on the data table that six of the temperatures were -2, +3, -5, 0, +4, and -1 but the last temperature was too blurry to read. What is the missing temperature?
A gentle reminder:
Assignment - In your comment remember to include the following:
* your name (first name and last initial)
* your class
* the answer to the problem – there are FIVE parts (or SIX including the bonus question) – be sure to include every part and number the expressions
* an explanation that includes the strategy you used to solve.
* is there another way to solve the problem?
* any additional thoughts you have about the problem(s)

Blog #2 - Due January 15, 2010
Blog Assignment #2 will focus on Writing Algebraic Expressions
"Let statements" are required for this assignment!!
Blog Assignment #2:
Pretend that you are planning for a Mavericks team trip to see a play live at Trinity Rep in Providence.
An adult ticket costs $50.
A child ticket (2-14 years of age) costs $10.
1. Write an expression for the total ticket cost in dollars if a adults and 85 students attend the production.
2. Write an expression for the total ticket cost in dollars if 8 adults and S students attend the production.
Wait, we almost forgot about transportation! If we were to need 2 buses to take us to Providence it would cost $750. The transportation cost will only be shared among the students since their ticket price is less than the adults.
3. Write an expression that represents the total cost for each student. (This means one expression that includes the price of the ticket to the play and his/her share of the cost of transportation.)
4. Now that you have your algebraic expressions, what will be the total cost for each student if 85 students go on the trip?
Reminder:
In your comment remember to include the following:
* your name (first name and last initial)
* your class
* the answer to the problem – there are FOUR parts – be sure to include every part and number the expressions
* an explanation that includes the strategy you used to solve.
* is there another way to solve the problem?
* any additional thoughts you have about the problem(s)
