Question Solved1 Answer To help counter terrorism and reduce crime (among other things), many countries are planning or have already developed computer-based surveillance systems that can track/identify their citizens and monitor their actions in public places. Clearly, this has privacy implications. Briefly describe your opinion about the ethics of working on the development of such system.

The work required to carry a particle with a charge of 10.0-μC from a 5.0-V equipotential surface to a 6.0-V equipotential surface and back again to the 5.0-V surface is: Question 11 options: a) 6.0 × 10–5 J b) 3.0 × 10–5 J c) 1.2 × 10–5 J d) 6.0 × 10–6 J e) None of the others are true

50 19. The following three histograms (A, B, and C) plot information about the number of hours of sleep adult Europeans get per night (Roenneberg 2012). One of them shows the frequency distri- bution of individual values in a random sample. Another shows the distribution of sample means for samples of size 10 taken from the same population. Another shows the 50 19. The following three histograms (A, B, and C) plot information about the number of hours of sleep adult Europeans get per night (Roenneberg 2012). One of them shows the frequency distri- bution of individual values in a random sample. Another shows the distribution of sample means for samples of size 10 taken from the same population. Another shows the distribution of sample means for samples of size 100. d.

One of them shows the frequency distribution of individual values in a random sample. Another shows the distribution of sample means for samples of size 10 taken from the same population. Another shows the distribution of sample means for samples of size 100. a. Identify which graph goes with which distribution. Please explain which features of these distributions allowed you to distinguish which was which. b. Estimate by eye the approximate population mean of the number of hours of sleep using the distribution for the data. c. Estimate by eye the approximate mean of individual values from a random sample (based on your choice in ?a?, above).

HW2.1. Finding the parametric solution Find the parametric solution of the following linear system: = -3 121 + 0x2 + 0x3 1x1 +-1x2 + 2x3 121 + 1x2 + 2x3 = -5 = -1 21= x1 { x 0% 22= X2 ? x 0% X3 = x3 ? 100% How to enter your answer: If you think that x1 = 2x2 + 3x3 + 5, then enter 2*x2 + 3*x3 + 5. If you think that X2 is free, then enter x2.
