A company is hiring people to read through all the comments posted on their website to make sure they are appropriate. Four people applied for the job and were given one day to show how quickly they could check comments. person 1 worked for 210 minutes and checked 50,000 comments. Person 2 worked for 200 minutes and checked 1,325 comments every 5 minutes. Person 3 worked for 120 minutes, at a rate of c = 331t, where c is the number of comments checked and t is the time in minutes. Person 4 worked for 150 minutes, at a rate represented by t = (3/800)c. Write equations for each job applicant that allow you to easily decide who is working the fastest.

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed

Christine wong has asked dave and mike to her move into a new apartment on sunday morning. she has asked them both, in case one of them does not show up. from past experience, christine knows that there is a 40% chance that dave will not show up and a 30% chance that mik a. what is the probability that both dave and mike will show up? (round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up? (round your answer to 2 decimal places.)e will not show up. dave and mike do not know each other and their decisions can be assumed to be independent.
