The reaction 2N2O5 ? 2N2O4 + O2 obeys the rate law:
rate = k[N2O5], in which the rate constant is 0.00757 s-1, at acertain temperature. If 3.09 moles of N2O5 was placed in a5.00-liter container at this temperature, how many moles of N2O5would remain after 0.52 minute and How long would it take for 72.0%of the original N2O5 to react?

Pu-239 is used in nuclear bombs. Its half-life is 24110 years. Assuming that losing 17% of the original plutonium deactivates the bomb, estimate how many years it would take for the bomb to become 'safe'.

What do the data show? Write a summary statement that communicates the "big idea" contained in the figure. Your summary statement should be written in such a way that if someone did not know the technical language in the figure, he/she could understand the *big idea.

Develop a series of bullet points that identifying essential details that substantiate your summary statement.

What, if any, information is missing from the figure? What more would you want to know in order to understand and evaluate the data? (Think about the issues raised by Joel Best in Damned Lies and Statistics.

In class this week we spoke about different imagining of futurities and how various media spaces take up them up (the genre of Afrofuturism, Indigenous TikTok, Queer fan fictions). 

Try and think of type of media you've engaged with that does this kind of "future" thinking-- one that imagines a future or a reality that is more capacious for varied lived experiences, one that acknowledges and engages with the past while nodding to the future (it might look like a type of genre, a film, a fanfic, a show, podcast/radio, etc.). Please share how you think this media does this and feel free to share links/images or other examples of it. 

Conjecture: |x| = c iff x = c or x = -c

steps:

1) x≥0 or x<0

2) x≥0 or x<0

3) so c = x, by hypothesis

4) If x < 0 then by definition |x| = x

5) By hypothesis |x| = c

6) so -x = c

7) and x = -c

My questions are:

a. Prove that the conjecture is false

b. check if each step in the argument is false

c. why is this not a proof?

d. Fix the conjecture by stating a similar result that begins “|x| = c iff…” and then prove it

Detection of saxitoxin in counterterrorism
using a commercial lateral flow immunoassay kit by Asuka Komano, Hisashi Maruko, Hiroshi Sekiguchi & Yasuo Seto. 

Answer the following question:

What was the rationale for seeing the results of the lateral flow immunoassay test strips when the saxitoxin was mixed with other compounds?

The company Pro Fish Sales Directors (PFSD ehf.) Maintains a sales department in Alaska and New York. The capelin shortage has put the company in a tight spot and either division needs to be closed. PFSD has obtained samples of sales figures from both places and wants to get you to help decide which department to close. The samples are independent and the company has decided that the decision will be made based on a 95% confidence interval on average sales. In Alaska, the average sale of the sample was ISK 580. a day. The number of sales examined was 29 and the standard deviation is ISK 27. a day. In New York, 11 sales were inspected, the average sales was ISK 500. per day and the standard deviation was ISK 99. a day.

a) PFSD ehf. assumes that the distribution in the sales of the departments is equal. Which division should the company close and why?

In 2001, the United Kingdom's economy exported goods worth £192 billion and services worth another £77 billion. It imported goods worth £225 billion and services worth £66 billion. Receipts of income from abroad were £140 billion while income payments going abroad were £131 billion. Government transfers from the United Kingdom to the rest of the world were £23 billion, while various U.K government agencies received payments of £16 billion from the rest of the world.

2001. Calculate the U.K. merchandise trade deficit for 2001. 
2002. Calculate the current account balance for 2001. 
2003. Explain how you decided whether payments on foreign investment and government transfers counted on the positive or the negative side of the current account balance for the United Kingdom in 2001.
