What is the main force acting on a projectile after it is launched (ignoring air resistance)?

An ensemble model uses majority voting with three independent classifiers. Each classifier has a 75% chance of making a correct prediction. What is the probability that the ensemble model makes a correct prediction for a given observation in general based on the probabilities?

An ensemble model uses majority voting with three independent classifiers. Each classifier has a 80% chance of making a correct prediction. What is the probability that the ensemble model makes a correct prediction for a given observation in general based on the probabilities?

Consider the graph of Lasso Logistic Regression model. Note a smaller value of C corresponds to a larger Lasso Logistic Regression penalty per the inverse relationship. Select all answers that are true.
