year, NOK 15,000 in two years and NOK 40,000 in five years. a) What is the present value of the company's cash flow if you use a discount rate of 10%? b) You read that an investment in team-building, which costs NOK 10,000, can give more motivated employees and increase sales. The increase in sales results in the following cash flow: NOK 2,000 in 1 year, NOK 7,000 in 2 years and NOK 5,000 in 5 years. Should you make this investment in team-building?

and how to solve: “A history lecture hall class has 15 students. There is a 15% absentee rate per class meeting. Find the probability that exactly one student will be absent from class.” I already know that: n = 15 p = 15% q = 1 - 15 = 1 - 0.15 = 0.85 ...and then you do: p (x = 1) = C 15 & 1 and then... (0.15)^1 (0.85)^14 Please help me understand the rest. Thank you!

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
