Below is your final assignment. Follow instructions at the top. I look forward to your amazing work.
Homework 22: Assigned 05.18. Due 05.21
Do the word problems on the sheet "Exponent_word.pdf" below.
Homework 21: Assigned 05.14. Due 05.18
Below are three columns: human years, cat years, and dog years.
we are going to assume that human years are the explanatory and they other two are response. find the lines of best fit for the following:
human years to dog years
what's the correlation?
human years to cat years
what's the correlation?
dog year to cat years (for this, make dog the explanantory)
what's the correlation?
if my dog has lived four years, how old would she be (according to your line of best fit)
if my cat is 95 in cat years, about how old is that in human years?
if my cat is 70 in cat years, what is that in dog years?
Assignment 3. Assigned 05.12. Due 05.19 by 4pm.
Assignment 3 is linked below. There is another sheet that goes with it. You have also been emailed these things.
Homework 19: Assigned 05.07. Due 05.11.
So your homework for Monday is a little different. you get some reading. this is a classic in the non-traditional mathematical canon. We are going to talk about it in class to start Thursday. You only need to read to the top of page 10, until the line "So how do we teach mathematics?" You can read further if you want to, but you are not required to.

Monday I will assign a week long assignment, and then we will have the final assignment quick after that, and then we're done!
Homework 18: Assigned 05.04. Due 05.07.
1) So last time I asked you to sample 15 random people and get their credits for this term.
Talk to me a bit about the process you used last time, and why it was not perhaps truly the best
Talk about any possibilities of undercoverage that would occur when considering asking people how many credits they are taking, and steps you could take to prevent that
Talk to me about how you plan on getting your new sample of 15 people
Get that new sample. Talk to me about any issues that arose in the way you tried to get that sample.
Find the mean of both your new sample and old sample and compare.
Find the range of both your new and old sample, and compare.
Do you think your sample is representative of the population of Bennington? Explain why you do or don't think so.
2) If all the precipitation for Bennington in one year happened at one time and in the form of a snow storm, how many feet of snow would that be? How long would this blizzard last? (use estimation, internet information, and other generalities. we will come up with a consensus in class)
Homework 17: Assigned 04.30. Due 05.04 (Star Wars Day)
1) find the expected value of that powerball ticket you have. here's a website to help you: http://www.powerball.com/powerball/pb_prizes.asp
2) A powerball ticket costs $2. This amount should be higher than the current expected value (the thing you found in question one). That being said, the expected value of a ticket increases as the jackpot value rises. At what jackpot level does the expected value become $2?
3) In class we played the game that if you rolled a 12 you won $50 and cost $2 to play. I want you to design two games. One of them should have an Expected Value that is in favor of the house (the non-player). Another should have an Expected Value that is in favor of the player. These two should be presented in a way where it is difficult to tell the difference. If these games need any tokens, dice, cards, whatever, you should bring them to class THURSDAY.
4) In class we discussed the odds for when we roll one die, and when we add up the dots on two dice. Figure out the odds for the sum of:
* 9 when rolling 2 dice
* 10 when rolling three dice
5) I flip a coin five times. What are the chances of me:
* flipping, in order: H, T, H, T, H
* flipping three heads and two tails in any order
* flipping five heads
6) I want you to sample 15 random students on campus and ask them how many credit hours they are currently taking. Bring these values to class on Monday for use.
Homework 16: Assigned 04.27. Due 04.30
1. This focuses on the Trigonometric movement. If you get stuck there are places online to help you, but don't jump there first. They may be using radians as well, so it may help you less than you think.
You are get into a ferris wheel, and are the last person to enter. The ferris wheel is three feet above the ground, completes a circle every 40 seconds, and has a diameter of 30 feet.
create an equation. You may want to use the desmos thing I made to help you. Link is http://www.desmos.com/calculator/qr9kz9lf2r
For how long in each rotation are you above 45 feet?
The ferris wheel stops after 4 minutes. where am I on the ferris wheel?
Extra: How fast is the ferris wheel going?
2. Glastonbury Mountain is just off to the east from here. There used to be a lot of people who lived there, but now it is mostly abandoned and part of the Bennington Triangle. Teenagers go up there, hang out and generally try to scare each other. But things are changing--people are moving in. Three families, in fact. They know each other well and are willing to share in some basic needs.
There are three houses. Call them A, B, and C.
These houses each need water coming from the well (W).
These houses each need electricity from the generator (G)
These houses each need propane from the shared Propane Tank (P)
You have plenty of piping for all of these different needs (W, G, and P), but there are some issues:
because you are on rocky ground, you cannot bury the pipes
none of the pipes can overlap
each person needs their own pipes from each utility directly to their house
This means that there are three different pipes from the Well that cannot overlap. These pipes also cannot overlap the three separate pipes from Propane, or the generator.
This family is depending on YOU to design the system for their utility needs. Design it in the best fashion--you may place the six objects wherever you want and make the pipes as convoluted as needed.
If, for some reason, you are not capable of accomplishing this task, dig into the reasons why. Attempt to come up with a reason that you are unsuccessful. A good, rational, clear reason.
