Mathematics: All Classes: Friday 4.28.06 Period 1
Broots was sitting behind the desk in front of the class. Two notices were printed on the board in rather shaky handwriting.
Beginners: Sit down and work quietly on your exam. You'll recieve your grades next Wednesday. Please come to class Friday.
Intermediate: If you showed up today, you're final project grade just went down.
Once everyone was sitting, he handed out the test.
1. Question one
2. Define if and only if
3. Please write out the times table for seven on the range one through ten.
4. Write a problem (and solve it) that shows a real world application of math.
5. A solution to the All King's Digits problem. (Use all ten digits to get 100)
6. What is the probability that a randomly drawn positive factor of 80 is less than 7?
Extra credit:
Three men walk into a motel and ask for a room. The desk clerk says a room is $30 so each man pays $10 towards the cost. Later, the clerk realizes he made a mistake, that the room should have been $25. He calls the bell boy over and asks him to refund the other $5 to the three men. The bellboy, not wanting to mess with a lot of change dividing the $5 three ways, decides to lie about the price, refunding each man $1 and keeping the other $2 for himself. Ultimately each man paid $9 towards the room and the bellboy got $2, totaling $29. But the original charge was $30, where did the extra $1 go?
[ooc: If you have the time, actually take the test as your character would. If not, jot down how well they did either on each individual question or over all. Test is open until next Wednesday.]

Re: Test
2. A phrase that connects two things and indicates that the truth of each statement depends on the truth of the other.
3. Pippi correctly writes out the times table for 7, she might be humming as she does this.
4. Pippi writes another problem about how pirates split loot and solves it.
5. Wrong by one number.
6. Also wrong.
Bonus Question:
Pippi indicates that the price isn't $30 anymore, so it can't be used as the start when adding it all up. The only missing dollars were the two that the bellboy kept. If the bellboy had really been smart. He'd have just kept the whole $5 for himself instead... The bellboy wouldn't have made a very good pirate.
Re: Test
2. In logic, 'If and only if' means that a statement can only be true when the other statement is true as well.
3. 1 x 7 = 7, 2 x 7 = 14, 3 x 7 = 21, 4 x 7 = 28, 5 x 7 = 35, 6 x 7 = 42, 7 x 7 = 49, 8 x 7 = 56, 9 x 7 = 63, 10 x 7 = 70.
4. If one potion requires 2 hawthorne flowers, and another potion requires requires 3, how many flowers will I need to make 5 of each?
(2*5)+(3*5) = 10 + 15 = 25 flowers.
5. (1+9)/(2+8)*(3+7)*(4+6)*5^0 = 100.
6. Factors of 80 = 1,2,4,5,8,10,20,40,80
# of factors of 80 = 9.
# of factors of 80 less than 7 = 4
Probobility of a factor of 80 being less than 7 = 4/9
Extra credit: You can't compare the 2 prices anymore; the $30 can't be used as a basis for the problem. The bellboy should have just given them the whole $5 and let them sort it out, anyway.
Note: Sir, I will not be in class next week, as my parents are calling me home early. I apologize for skipping the last classes.

Re: Test
2. It means that one thing is only true if certain other things are true.
3. 1X7=7, 2X7=14, 3X7=21, 4X7=28, 5X7=35, 6X7=42. 7X7=49, 8X7=56, 9X7=63, 10X7=70
4. Math class is at 8 am. Student M usually hits her snooze alarm four times before getting up. The snooze lasts four minutes. It takes Student M eight minutes to get ready for class and five minutes to get to class from her room if
Ishe runs. How early does Student M have to set her alarm clock in order to barely get to class on time?(4 X 4) + 8 + 5 = 29 minutes. So, alarm must be set for at least 29 minutes before 8 am. If alarm is set for 7:30 am, Student M will make it to class with one minute to spare.
5. ...
6. A little bit less than half?
EC: Trick question. The new total is $25, not $30 anymore. The $2 taken by the bellboy (who really should have just kept the whole $5 to save him from any math at all) should have been subtracted from the total paid by the three guests, not added to it.
Re: Test
2. "If and only if" is a connective between statements which means that the truth of either one of the statements requires the truth of the other. Thus, either both statements are true, or both are false.
3. 1x7=7, 2x7=14, 3x7=21, 4x7=28, 5x7=35, 6x7=42, 7x7=49, 8x7=56, 9x7=63, 10x7=70
4. Cameron describes a problem on how to calculate the time of arrival of an F-16 leaving its base to attack a target.
5. 90 - (5*4) + (8*7) + 6 - (32*1) = 100
6. Cameron gets this wrong.
EC: The butler ran off with it.
Re: Test
2. Define if and only if: Result is exclusive to previous requisites.
3. Please write out the times table for seven on the range one through ten.
7 x 1 = 7
7 x 2 = 14
7 x 3 = 21
7 x 4 = 28
7 x 5 = 35
7 x 6 = 42
7 x 7 = 49
7 x 8 = 56
7 x 9 = 63
7 x 10 = 70
4. Write a problem (and solve it) that shows a real world application of math.
A box holds 50 rounds. A clip holds 12 rounds. How many clips can you load from 1 full box and 1/2 of a box? 6 full clips and 1/4 of a clip.
5. A solution to the All King's Digits problem. (Use all ten digits to get 100) hANDWAve
6. What is the probability that a randomly drawn positive factor of 80 is less than 7? Handwave but almost right
Bonus: Bellboy's pocket
