What are the first ten prime numbers? - Answer-2, 3,5, 7, 11, 13, 17, 19, 23, 29 Sum of two primes - Answer-All prime numbers are odd, except the number 2. Thus, the sum of any two primes will be even unless one of those primes is the number 2 If a sum of primes is odd, one of those primes must be the number 2 Counting total factors - Answer-If a number has prime factorization a^w x b^y x c^z (where a, b, and c are all prime), then the number has (w +1)(y + 1)(z + 1) different factors ...

when might overfitting occur - Answer- when the # of factors is close to or larger than the # of data points causing the model to potentially fit too closely to random effects Why are simple models better than complex ones - Answer- less data is required; less chance of insignificant factors and easier to interpret what is forward selection - Answer- we select the best new factor and see if it's good enough (R^2, AIC, or p-value) add it to our model and fit the model with the current set ...

Python Chapter 8 Questions and Answers Already Passed What is the simplest way to create a list of numbers from 1 to 5? Use `list(range(1, 6))`. How do you make a list contain the word "Python" five times? Use `["Python"] * 5`. What happens if you try to modify a tuple? Python raises a `TypeError` because tuples are immutable. How can you swap the first and last elements of a list? Use `list[0], list[-1] = list[-1], list[0]`. How do you create a list of the sq...
