Part C Ionic compounds are formed from ionic bonds, whereby an electron is transferred from the metal cation to the nonmetal anion. Ions form solid lattices of ions. Covalent compounds form solids through the attraction of two covalent molecules. Since the attraction between two covalent molecules is weak compared to the ionic bonds holding an ionic compound together, ionic compounds tend to have higher melting points. Which of the following compounds has the highest boiling point? Br2 NaBr HBr BrF

To estimate the number of fish in a lake, scientists use a tagging and recapturing technique. A number of fish are captured, tagged, and then released back into the lake. After a while, some fish are captured and the number of tagged fish is counted. Let T be the total number of fish captured, tagged, and released into the lake, n the number of fish in a recaptured sample, and t the number of fish found tagged in the sample. Finally, let x be the number of fish in the lake. The assumption is that the ratio between tagged fish and the total number of fish in any sample is approximately the same, and hence scientists assume t/n = T/x. Suppose 151 fish were captured, tagged, and released. Then 22 fish were recaptured, and among them 11 were found to be tagged. Estimate the number of fish in the lake. There are approximately fish in the lake.

What is a theory for Mary? Mary, single, age 36 came to see you because she has struggled for many years with a sense of worthlessness. She has had many men in her life, and she has felt used most of the time. She said that her "boundaries are all screwed up". She lets in men who take advantage of her, but for some reason she isn't attracted to men who treat her well. As you begin to explore her background, she talks about her father sexually abusing her until about age 14. She said she knows her mother knew it was going on but she turned a blind eye. "From the outside, our family looked normal, and everyone at church thought we had a model family. My parents were involved in church activities, and my dad served on the elder board. Mary has struggled with relationships, largely out of a fear of getting close to anyone. She often stays home alone with her cats. When it is too much she seeks connections with people, which is often disappointing. She occasionally struggles with thoughts about life not being worth all of the pain. She said she drinks every day, but not usually to the point of intoxication. "It just takes the edge off", she says.

Evaluate the limit as x approaches 0 from the left of e^(2 / x). If we let t = 2/x, we know that t approaches negative infinity as x approaches 0 from the left. Therefore, by the limit as x approaches negative infinity of e^x = 0, the limit as x approaches 0 from the left of e^(2 / x) = the limit as t approaches negative infinity of e^t = 0

Identify any lurking variables that could interfere with this study. Choose all that apply. Hair color. Driving experience. Type of phone. Texting ability. 2 Multiple Choice 1 point You are concerned about the effects of texting on driving performance. Design a study to test the response time of drivers while texting and while driving only. You will examine how many seconds it takes for a driver to respond when a leading car hits the brakes. How can blinding be used in this study? - The person driving the vehicle could wear a blindfold. The person driving the vehicle could not know who is texting them. The person driving the vehicle could not know if they are texting or not. The researchers observing the trials and recording response time would not know if the driver was texting and driving or only driving. Submit

A cell phone manufacturer tests the battery lifetimes of its cell phones by recording the time it takes for the battery charges to run out while testers are streaming videos on the phones continuously. The manufacturer claims that the population mean of the battery lifetimes of all phones of their latest model is 5.74 hours. As a researcher for a consumer information service, you want to test that claim. To do so, you select a random sample of 45 cell phones of the manufacturer's latest model and record their battery lifetimes. Assume it is known that the population standard deviation of the battery lifetimes for that cell phone model is 2.42 hours. Based on your sample, follow the steps below to construct a 90% confidence interval for the population mean of the battery lifetimes for all phones of the manufacturer's latest model. Then state whether the confidence interval you construct contradicts the manufacturer's claim. (a) Click on "Take Sample" to see the results from your random sample of 45 phones of the manufacturer's latest model. Number of phones Sample mean Sample standard deviation ------------ ------------- ------------- 45 5.47 2.13 Population standard deviation ------------ 2.42 Enter the values of the sample size, the point estimate for the population mean; the population standard deviation, and the critical value you need for your 90% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute". Sample size: Point estimate: Standard error: Population standard deviation: Critical value: Compute (b) Based on your sample, graph the 90% confidence interval for the population mean of the battery lifetimes for all phones of the manufacturer's latest model. - Enter the lower and upper limits on the graph to show your confidence interval. - For the point (4), enter the manufacturer's claim of 5.74 hours.
