Hi there i need help with my chemistry lab thank you

if a graduate went on to college full time, there was a 23% chance that they would work at the same time. If a graduate attended college part time, there was a 79% chance that they would work at the same time. If a high school graduate didn't go on to college, there was a 93% chance that they would work. At the time of the survey, 66% of high school graduates attended college full time and 20% of high school graduates attended college part time. If a randomly selected high school graduate worked, what is the probability that they attended college full time? Enter your answer in decimal form and round to four decimal places if necessary. You may want to look at pages 42 through 45 in the notes (videos 30 through 32). If a randomly selected high school graduate worked, probability that they attended college full time =

I am in desperate need of help. There questions are in accordnce wih the AUDITORY CORTEX 1. How is sound intensity encoded? (I am not sure if these means how is it measured...?) What is a rate level function? What is the tonotopic map of the cochlea? What is a tuning curve ? What is the best frequency? What is the threshold ? What is the Volley Theory? I have an idea of the material since it was review in class but the PowerPoint slides are hard to understand. 2. Describe the concept of sound localization and the coincidence detection model of binaural processing occuring in the superior olivary nucleus that mediates sound source localization? (I don't even know where to start with that one) 3. Distinguish between the neural circuit processing intetnaural time differences intetnaural level differences? How and where are the signals compared? (I understand the level vs time difference but I do not know about the neural circuit processing... And what does it mean by where are the signals compared?) 4. Understand the gross organization of the auditory cortex: primary AI and secondary AII auditory cortex, tonotopic organization. I am using the textbook brain and behavior 4th edition by Bob Garrett and also the review PowerPoint slides given to the class but it is mostly charts and graphs
