In supervised machine learning, which steps are taken to determine how well a machine learning model will predict labels in the future? Select all that apply. a) Determine the correct labels for each observation in a data set
b) Do not determine the correct labels for any observation in a data set
c) Train the machine learning algorithm on part of the data that is unlabeled
d) Train the machine learning algorithm on part of the data that is labeled
e) Test the machine learning algorithm on previously seen data that is unlabeled
f) Test the machine learning algorithm on previously seen data that is labeled
g) Test the machine learning algorithm on previously unseen data that is unlabeled
h) Test the machine learning algorithm on previously unseen data that is labeled
i) Measure how well the machine learning algorithm predicts labels on unseen data
j) Measure how well the machine learning algorithm predicts labels on seen data

Create a function (prob3_6) that will do the following: input a positive scalar integer x. if x is odd, multiply it by 3 and add 1. if the given x is even, divide it by 2. repeat this rule on the new value until you get 1, if ever. your program will output how many operations it had to perform to get to 1 and the largest number along the way. for example, start with the number 3: because 3 is odd, we multiply by 3 and add 1 giving us 10. 10 is even so we divide it by 2, giving us 5. 5 is odd so we multiply by 3 and add one, giving us 16. we divide 16 (even) by two giving 8. we divide 8 (even) by two giving 4. we divide 4 (even) by two giving 2. we divide 2 (even) by 2 to give us 1. once we have one, we stop. this example took seven operations to get to one. the largest number we had along the way was 16. every value of n that anyone has ever checked eventually leads to 1, but it is an open mathematical problem (known as the collatz conjectureopens in new tab) whether every value of n eventually leads to 1. your program should include a while loop and an if-statement.
