What is a residual? What does it mean when a residual is positive? Choose the correct answer below. ◻ A. A residual is the difference between an observed value of the response variable y and the predicted value of y . If z is positive, then the observed value is greater than the predicted value. ◻ B. A residual is the difference between an observed value of the response variable y and the value of the contesponding explanatory variable x . If E is positive, then the response variable is gra than the explanatory variable. ◻ C. A residual is the difference between an observed value of the response variable y and the average value of the response variable. If it is positive, then the response variable is greater than mean. ◻ D. A residual is a data point that does not fit the pattern of the rest of the data, il it is positive, then the data point should still be included in the data set. Time Remainings; 02-45-51

User Suppose the daytime processing load consists of 70% CPU activity and 30% disk activity. Your customers are complaining that the system is slow. After doing some research, you have learned that you can upgrade your disks and make them 3.5 times as fast as they are currently are. You have also learned that you can upgrade your CPU to make it 1.4 times faster than it currently is. You have time to implement one upgrade. Which one do you choose and Why? by Amdahls law

(8 pts) A single-dwell (RFD) cam is designed using the 3-4-5-6 polynomial to lift and lower a follower by 2.5" in 100° then dwell for the remainder. The total cycle takes 3 seconds. Show your work for all parts. a. Determine the angular velocity. Assume that it is constant throughout the cycle. rad/s b. What is the camshaft angle when x = 0.3? degrees Is this part of the rise or fall? c. For the same camshaft angle in (b), determine the acceleration of the follower. The equation for normalized follower acceleration is $y'' = 384x - 2304x^2 + 3804x^3 - 1920x^4$. in/s²
