Abank's risk analyst is in charge of offering credit to people with good credit histories. suppose that chase bank is predicting how much debt a person will accrue on a new credit card (in $) as a function of their credit score (a number between 300 and 850, measured in credit score units). a person with a credit score of 400 credit units averages a debt of about $9,000 and a person with a credit score of 700 credit units averages a debt of about $2,500. calculate the rate of change. provide a numerical answer (do not use units). round to the nearest whole number.

An electronics manufacturer wants to know if customers would be interested in a detachable keyboard for their tables and if so, what the most important features would be. the manufacturer partners with an electronics store to include copies of the survey with every purchase at that store for one week. which of the following best explains why this random sample is unlikely to be a good representative sample of tablet owners' preferences for a detachable keyboard? a) one week is likely not enough time to get a large enough sample. b) most people won't bother to send in the survey, which is likely to skew the results c) there is no way to verify whether the responders to the survey actually own a tablet d) the survey is biased because it was conducted through an electronics store, not the general population
