Answer to the nearest millimetre.b What is the precision or limit of reading?c What the largest possible absolute error?d What is the upper and lower bound for each measurement?e Calculate the relative error, correct to three decimal places, for each measurement.f Calculate the percentage error, correct to one decimal place, for each measuremen

48.Consider a model that predicts 150 examples for the positive class, 95 are correct (true positives), meaning five were missed (false negatives) and 55 are incorrect (false positives). What will be the precision?  A. 55/150  B. 95/150  C. 55/95  D. 150/55

The rational number that represents the sample screen’s length compared to the required length is [DROP DOWN 1].The absolute value of the sample screen’s length compared to the required length is [DROP DOWN 2].Another sample screen could have the same absolute value if it was [DROP DOWN 3].
