Question A whale swims due east for a distance of 2.5 km, turns around and goes due west for 6.9 km, and finally turns around again, and heads 3.7 km due east. What are the total distance traveled and the magnitude and direction of the displacment of the whale? Plot position vs time (2 pts) Initial data (1 pt) (define symbols for individual displacements) Fundamental formulas (connect initial data symbols to distance and net displacement) (2 pts) Numerical calculations (substitute initial data and compute) (2 pts) Final answers (3 pts):

Current Attempt in Progress Consider 5.0 pounds per minute of water vapor at 100 lbf/in2, 500°F, and a velocity of 100 ft/s entering a nozzle operating at steady state and expanding adiabatically to the exit, where the pressure is 40 lbf/in2. The isentropic nozzle efficiency is 85.0%. Determine the velocity of the steam at the exit, in ft/s, and the rate of entropy production, in Btu/min.OR. Step 1 Your answer is correct. Determine the velocity of the steam at the exit, in ft/s. V2 = 1910.2691 ft/s Hint Attempts: 1 of 4 used Step 2 * Your answer is incorrect. Determine the rate of entropy production, in Btu/min:OR. 012 = i 0.015 Btu/min."

Problem 1: Logistic Regression Basics - Odds and Ends a) What is the equivalent odds for the probability 0.25? b) You are testing a new drug and have gathered binary data on whether the drug performed its desired effects. From the control trial, 102 people saw improvement with a placebo and 241 did not. With the drug, 67 people saw improvement and 82 did not. What is the odds ratio of these results? c) You've decided to determine the probability of a picture containing an animal on social media. On 6 different days, you look at 10 random pictures and record the number of pictures that contain at least one animal, and get the values {6,10,7,9,5,9}. Given these results, what is the MLE for the probability of a picture containing an animal?
