The estimated average concentration of NO2 in air in the United States in 2006 was 0.016 ppm.

Calculate the partial pressure of the NO2 in a sample of this air when the atmospheric pressure is 748 torr (99.7 kPa ).

How many molecules of NO2 are present under these conditions at 17 ∘C in a room that measures 16 × 11 × 6 ft ?

1. Between 2006 and 2009, Betty appeared in 23 episodes of The Bold and The Beautiful. The work was quite different from her time on sitcoms. This led her to think about the following hypotheses:

H₀: Soap opera acting is the same difficulty as sitcom acting

H_a: Soap opera acting is harder than sitcom acting

Describe what a Type I error would look like in the context of this scenario.

In 2006 the State of Indiana in the USA sold a 75-year concession to operate and maintain the East-West Toll Road. Before doing so, it commissioned a consulting report that estimated the value of the concession. Table 1 shows the forecasted cash flow from the toll road.

Calculate the present value of the concession using a discount rate of 6%. Cash flows are reported in Table 1 for each ten-year block up until 2066–2075 with the last block as five years (2076–2081). Assume in your calculations that cash flows are spread evenly during those blocks. Explain your calculations showing for each year the applicable discount rate and for each block the present value.

PS:please calculate in order to see and understand the PV for each block

Below provides a summary of US current account in the year 2006 (in billions of $)

a) Should the US be concerned about its current account balance? Why or why not? What are the possible reasons for this observation?

1. Use this data from the 2006 GSS to determine if there is a significant relationship between marital status and happiness. Use the five step model and describe each step.

In 2006​, there were 11,300 students at college​ A, with a projected enrollment increase of 800 students per year. In the same​ year, there were 30,900 students at college​ B, with a projected enrollment decline of 600 students per year. According to these​ projections, when will the colleges have the same​ enrollment? What will be the enrollment at that​ time?

Between 2006 and 2008, Sony and Toshiba were in a format war in the market for

high-definition optical discs. Sony had developed Blu-ray discs whereas Toshiba

had developed the HD-DVD format. Both producers were manufacturing players

for their own format. However, unless Sony and Toshiba agreed on producing

only one particular format, consumers were holding off their purchases. They

feared, should they buy a player, that they risked having invested in the wrong

format, leaving them unable to play content on high-definition optical discs. Both

producers could choose either format in the production of players. Sony could

produce HD-DVD players; in that case, they would have to pay $20 Billion royalties

per year to Toshiba if they sell any players. Toshiba could produce Blu-ray players;

in that case, they would have to pay $20 Billion royalties per year to Sony if they

sell any players. Assume that, if Sony and Toshiba agree on one format, they

would have a profit of $100 Billion in players each per year before eventual royalty

payments.

(a) What are the components of a strategic game? Model the interaction be-

tween Sony and Toshiba as a strategic game, in which Sony's and Toshiba's

strategies are given by the format of the high-definition disc players they

produce and their preferences are given by their profits after paying for or

receiving royalties.
