1. The demand for chocolate chip cookies is given by equation 1, where Qd is the quantity of cookies demanded in a year (in millions), and P is the price per cookie (in dollars).



Qd = 8 - 30*P (1)





The supply of chocolate chip cookies is given by equation 2, where Qs is the quantity of cookies supplied (in millions):



Qs = -2 + 20*P (2)









a. Draw the demand curve and the supply curve for chocolate chip cookies, labeling your axes and the curves. (Put P on the vertical axis, Q on the horizontal axis. Substitute values for P (start with $.10 and use increments of $.10) and solve for Qd and Qs.)



b. Show the equilibrium price and quantity by drawing dashed lines from the equilibrium to each axis.

I know about just one way that by using a conductive cover, and making the current in the cover, we can isolate inside the cover.
But I think in this way, we should access to the earth, but in the case we don't access directly to the earth (or access is throgh a high resistance material), is there any alternative way? (maybe not using conductive material?)

im thinking this. air being foced into a chamber with water inside and blown directly onto water, then the air being forced out of another tube. im hoping that the air that is passed through the chamber and onto the water will come out of the tube chilled. well colder, hopefully as cold as possible.

im basing this as the air will open up in a chamber like an expansion chamber, pass over the water (for some reason i beleive this will cool it some how) and the air will be forced back out of the tube cooler than before.

the air will be coming through the first tube with some velocity, of approx 50mph. so im figuring that it will push the air back out of the vacant tube. the chamber will obviously be sealed so that there will only be one way for the air to go.

but im no scientist, will this chilling happen?

I need to test if two populations of stock returns are correlated. Their correlation is 0.21. How do I draw a conclusion if that number is indeed statistically significant? Do I have to conduct a hypothsis testing? if yes what "test statistic" would I use?

Looking to find the conversion formula or "tool" to figure the difference between:

1st conversion request: $ 82 million in 1981 vs. 2006

Couple of factors: public bonds sold to finance project, rural mountains of Colorado, water works project - flood control & water storage, owner/operator - municipality, Army Corp of Engineers oversight.

2nd conversion request: $ 101 million in 1985 vs. 2006.

Couple of other factors: public bonds sold to finance project; locale - Boise, ID; hydro-electric power plant(revenue generator); secondary function to water works project - flood control & water storage, owner/operator - municipality, Army Corp of Engineers oversight, etc.

I'm currently working on $ 333M const. project; city of San Francisco is client/owner once complete.

It would be great if any of you could help figure out the difference in value to the different projects here. Very curious.

Thank you for your help.

1) 3 x 1/4? I'm being a bit silly but is this 3/4 or 3/12?

How do you add surds, I'm slightly confused!

2) 2 root 2 + root 2? Would that be 2 root + 1?

3) root 2 + root 2?

Thanks. :o)

The story of creation states that Adam and Eve are first human creations thus we are their descendants of different races. How would you explain it genetically.

I think you have to use relativity, because there are 31,536,000 seconds in a year, and g = 10m/s/s, so if you were to use Newtonian equations you'd be going faster than the speed of light (300,000,000 m/s). So how do you do this???
