Bagging (weka. classifiers. meta. bagging). you will use decision tree (weka. classifiers. trees. j48) as the base supervised learner. try trees of different depth (1, 2, 3, 5, 10) and different sizes of bag or ensemble, i. e., number of trees (10, 20, 40, 60, 80, 100). compute the training accuracy and testing accuracy for different combinations of tree depth and number of trees; and plot them. list your observations.

What is the simplified expression for 6(2(y+x))

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?

For the chance to be team captain, the numbers 1-30 are put in a hat and you get two chances to pick a number, without replacement. which formula correctly shows how to find the probability that you choose the number 1 and then 2?
