When a man returns to his well-sealed house on a summer day, he finds that the house is at 35°C. He turns on the air conditioner, which cools the entire house to 20°C in 30 min. If the COP of the air-conditioning system is 2.8, determine the power drawn by the air conditioner. Assume the entire mass within the house is equivalent to 800 kg of air for which $c_v = 0.72 \, kJ/kg \cdot °C$ and $c_p = 1.0 \, kJ/kg \cdot °C$.

What are colligative properties? Check all that apply. Colligative properties are properties that depend on the amount of solute and does not depend on the type of solute. Colligative properties are properties that depend on the type of solute and does not depend on the amount of solute. Dependence of the solubility of a solid on a temperature is an example of colligative properties. Boiling point elevation is an example of colligative properties. Freezing point depression is an example of colligative properties. Osmotic pressure is an example of colligative properties. Vapor pressure lowering is an example of colligative properties.

(1) Determine your own height in meters, and your mass in kg. (II) To the correct number of significant figures, use the information inside the front cover of this book to deter- mine the ratio of (a) the surface area of Earth compared to the surface area of the Moon, (b) the volume of Earth compared to the volume of the Moon. 18. (II) Would a driver traveling at 15 m/s in a 35 mi/h zone be exceeding the speed limit? Why or why not? 19. (II) The age of the universe is thought to be about 14 billion years. Assuming two significant figures, write this in powers of 10 in (a) years, (b) seconds. 20. (II) The Sun, on average, is 93 million miles from Earth. How many meters is this? Express (a) using powers of 10, and (b) using a metric prefix (km).

In marketing, response modeling is a method for identifying customers most likely to respond to an advertisement. Suppose that in past campaigns 31.6% of customers identified as likely respondents did not respond to a nationwide direct marketing campaign. After making improvements to their model, a team of marketing analysts hoped that the proportion of customers identified as likely respondents who did not respond to a new campaign would decrease. The analysts selected a random sample of 1500 customers and found that 441 did not respond to the marketing campaign. The marketing analysts want to use a one-sample z-test to see if the proportion of customers who did not respond to the advertising campaign, $p$, has decreased since they updated their model. They decide to use a significance level of $\alpha = 0.05$. Select the correct null ($H_0$) and alternative ($H_1$) hypotheses. $H_0: p = 0.294$ and $H_1: p < 0.294$ $H_0: p = 0.316$ and $H_1: p \neq 0.316$ $H_0: p = 0.316$ and $H_1: p < 0.316$ $H_0: p = 0.316$ and $H_1: p < 0.316$ $H_0: p = 0.294$ and $H_1: p < 0.294$ Determine the value of the z-statistic. Give your answer precise to at least two decimal places. -3.69 Incorrect Determine the $P$-value for this test. Give your answer precise to at least three decimal places. 0.0002 P-value: Incorrect
