Answer 1

Q. 3 : answer c) Linear Function

Mathematical functions in which each variable appears in a separate term and is raised to the first power are called linear functions.

Q.5. answer : c) 27.33%

Error rate is calculated as the total number of two incorrect predictions (FN + FP) divided by the total number of a dataset (P + N). overall error rate = (82/300 )*100 = 27.33%

Q.6 Answer : c) restrictions that limit the settings of the decision variables.

Q.21 answer : b. [0, 1)

Q. 22 answer : a) 22.54%

Error rate of class 1 = 100- number of correct positive predictions divided by the total number of positives*100

Error rate of class 1 = 100 - (110/142) *100

= 22.54%
