1. For Part 2: SingleDisplacement Reactions: For each of the four singledisplacement reactions, describe what happened in each well. If a chemical reaction occurred, write a balanced equation for it. Then using the A, B symbols, write a general equation for a singledisplacement reaction.
Here are the chemical formulas of the reactants for each reaction:
• zinc – Zn
copper sulfate – CuSO4
• aluminum – Al
copper sulfate – CuSO4
• zinc – Zn
silver nitrate – Ag(NO3)
• copper – Cu
silver nitrate – Ag(NO3)

Abstract
As I reflect back on this course all I see are added benefits. As teachers we are always learning through new experience and materials. MTH156 was a very helpful course which enabled us to learn mathematical procedures and effectively utilize them in the classroom. The art of becoming a teacher is rewarding all on its own. The joys and thrills of holding your...
...1. a) Follow the instructions in the applet to fill out the 1st graphs then answer the following question: What is the impact of the new point on the standard deviation?
The new point has made the standard deviation to go up to over 2.07
b) Follow the instructions to create the next two graphs then answer the following question: What did you do differently to create the data set with the larger standard deviation.
What I did differently was to have two outliners on both ends of...

Q=Sullivan handbags marks up their bags at 45% of the selling price. Pat Sullivan saw a bag at a trade show that she would sell to her customers for $85. What is the most she could pay for the bag and still retain the 45% markup of the selling price?
P=selling price
C=cost of product
R=percentage markup
P=C(1+r)
85=C(1+45%/100=1.45)
C=85/1.45=58.62
Check back
58.62*45%=26.379=26.38
58.62+26.38=85
