Very briefly: does this table give any useful information regarding the effectiveness of neighborhood watches for reducing property crime? If yes, what is that information? If no, why not? 

Cloudy County is also concerned about its property crimes. The County Commissioner asks you to do some analysis of the distribution of property crimes based on data from many prior years. Historically, the number of property crimes are normally distributed with a mean of 500 and a standard deviation of 60.  You will be asked to show your work as a file upload on the next question, so keep it handy.   a. Based on the information above, what proportion of years (i.e. what proportion of the data) had a number of property crimes greater than 525? Round your final answer to the third decimal place. [answera] b. Based on the information above, what proportion of years (i.e. what proportion of the data) had a number of property crimes between 450 and 550? Round your final answer to the third decimal place. [answerb] c. Last year, Cloudy County experienced a crime wave. Only 2.56 percent (so, proportion = 0.0256) of previous years had a higher prevalence of crime. How many crimes did Cloudy County have last year? [answerc]

From the list below, select the true statements regarding the function f(x)=2+ln x-1{“version”:”1.1″,”math”:”f(x)=2+ln x-1″}. (Select all of the true statements.)

The graph of f(x) is given.  What intervals are the solutions to the inequality  f(x)

Which of the following would be the proper way to solve the inequality  |3-5x|

The rules of exponents indicate that   xx2-4{“version”:”1.1″,”math”:”xx2-4″} can be simplified to xa  where a is  a   is a real number. What is the correct value of a ? Only type the number in the blank below. If a is a fraction, write it using the slash. For example, 57=5/7{“version”:”1.1″,”math”:”57=5/7″}.  _______
