When the goal is to accurately classify the top tier of a new sample rather than accurately classify the entire sample, these charts are used to assess performance? 1 bar,2 lift, 3 decline charts, 4 none
this means that the observation belongs to one class but the model classifies it as member of a different class? 1 average error, 2 misclassification error, 3 prediction error, 4 all
a very simple rule for classifying a record into one of m classes, ignoring all predictor information that we may have, is to classify the record as a member of the majority class? 1 classification matrix rule, 2 class separation rule, 3 naive rule, 4 none
a popular method of plotting the pairs (sensitivity, 1-specificity) as the cutoff value increases from 0 and 1. 1 roc curve, 2 scatter plot, 3 lift charts, 4decile charts
when classifying data with very low response rates, practitioners typically. 1 train models on data that are 50% responder, 2 train models on data that are 50% nonresponder, 3 validate the models with an unweighted sample from the original data, 4 all the above

Step-by-step explanation:
the 2nd line can be rewritten as y < x-3
So, any value that is less than both 4x+4 and x-3 will work
Pick any value you want for x, and figure y possibilities
x=0; x-3=-3, 4x+4=4, so y<-3 ... (0,-5) will work
I'm sure you can now come up with other pairs.
