9 years ago Mary purchased shares in a certain mutual fund at Net Asset Value (NAV) of $97. She reinvested her dividends into the fund, and today she has 8.7% more shares than when she started. If the fund's NAV has increased by 39.5% since her purchase, compute the rate of return on her investment if she sells her shares today. Round your answer to the nearest tenth of a percent.

I was already given the correct answers, but I want to know the proper way to solve! Thanks. 1) Joanna commutes to FIU from her home in Broward 5 days each week (Monday - Friday). The probability that Joanna experiences heavy traffic during her morning commute is 0.3. On average, how many days each week does Joanna expect to experience heavy traffic during her morning commute? Assume the number of days of traffic Joanna experiences in a week follows a binomial distribution. A. Cannot be Determined B. 1.0 days C. 1.5 days (Correct) D. 3 days E. 5 days 2) Joanna commutes to FIU from her home in Broward 5 days each week (Monday - Friday). The probability that Joanna experiences heavy traffic during her morning commute is 0.3. What is the probability that Joanna experiences exactly two days of heavy traffic during her morning commute in a given week? Assume the number of days of traffic Joanna experiences in a week follows a binomial distribution. A. 0.31 (Correct) B. 0.36 C. 0.47 D. 0.53 E. 0.84

Current Attempt in Progress This exercise provides information about data in a survey of students. The math SAT score is higher than the verbal SAT score for 178 of the 341 students who answered the questions about SAT scores. Find $\hat{p}$, the proportion for whom the math SAT score is higher. Round your answer to three decimal places. $\hat{p}$ =

Given the following dataset consists of two classes (triangle and circle), identify the machine learning algorithm that can achieve zero training loss. Select one or more: a. Decision Tree b. k-Nearest Neighbors c. Kernel SVM d. Logistic Regression e. Perceptron f. Linear soft-margin SVM 2. Corrected_text: Identify which of the following statements about Perceptron is FALSE. Select one or more: a. A linear classifier b. The output is probabilistic in the range of 0 and 1 c. Heaviside function is used to apply to obtain the prediction. d. Attributes or features are equally important. 3. Corrected_text: A data scientist just trained a decision tree classifier for brain tumor detection application. He/She notices a very low training error but abnormally high test error. He/She also notices a linear soft-margin SVM classifier performs much better than the decision tree classifier. Identify the cause of the problem. Select one or more: a. The decision tree is overfitting b. The decision tree is too shallow c. The size of the dataset is small d. The decision tree is too deep Title_with_topic: Machine Learning Algorithms, Perceptron, Decision Tree Classifier
