answers to the following questions. (a) If events A and B are mutually exclusive and collectively exhaustive‚ are Ac and Bc mutually exclusive? Solution Ac ∩ Bc = (A ∪ B)c = Ωc = ∅. Thus the events Ac and Bc are mutually exclusive. (b) If events A and B are mutually exclusive but not collectively exhaustive‚ are Ac and Bc collectively exhaustive? Solution Let C = (Ac ∪ Bc )c ‚ that is the part that is not contained in Ac ∪ Bc . Using De Morgan’s Law C = A ∩ B = ∅. Thus‚ there is nothing that is

me into possible solutions to these complications. One solution could be to build dams to hold back the floodwaters. Another solution would be straightening rivers to increase the speed of the river to remove water from affected areas. Levees and embankments can prevent rivers from overflowing by increasing the height of the riverbanks to allow more water to be contained. Dredging can make a channel deeper‚ and free of sediment so it can contain more water. But these solutions have its disadvantages

Maddison Thorne 9.11.14 Aim: To use first hand and secondary sources to gather‚ process‚ analyse and present information to identify examples of suspensions‚ colloids‚ and solutions and outline one advantage of a mixture being in each form. Materials: Four 250ml beakers 200ml of 0.01m salt solution. 200ml of colloid milk( mix two teaspoons of milk powder in 200ml of water) 200ml of suspension (muddy water‚ diluted water-based paint) Filter paper Filter funnel‚

constant speed of 2.0 m/s2 . (b) The elevator has a constant upward acceleration of 2.0 m/s2 . (c) The elevator has a constant downward acceleration of 2.0 m/s2 . (d) The cable snaps and the elevator falls freely (ignore friction and the bloody end!). SOLUTION: The weight of the person depends on Mass and g‚ therefore: W = M g = (70.0 kg) 9.80 m/s2 = 686 N downward in all cases (a)-(d). Using the free-body-diagram for the person is shown to the right‚ We solve for N (which equals to what the scale reads)

and population growth over the course of the past few centuries. Scientists are frenetically searching for the solution to this issue‚ and their outcomes are bleak. They are telling the world that if population growth does not slow‚ the earth will swell to a capacity too large to sustain itself and the conclusion will be apocalyptic. Explanations are numerous‚ however viable solutions are difficult to find. Adherents to the Malthusian theory‚ such as Garrett Hardin‚ author of the article There

Solution To Teen Violence Every year‚ nearly one-million twelve to nineteen year olds are murdered robbed‚ or assaulted many by their peers and teenagers are more than twice as likely as adults to become the victims of violence. Although the problem is far too complex for any one solution‚ teaching young people conflict resolution skills‚ nonviolent techniques for resolving disputes seems to help. To reduce youth violence‚ conflict resolution skills should be taught to all

DETERMINATION OF THE HEAT OF SOLUTION BY THE VANT HOFF ISOCHORE METHOD Jan Vincent Arafiles‚ Merry Joy Arzaga‚ Anne Louise Ayson‚ Lovely Jenny Buenaflor Group 2 3A-Biochemistry chem401 laboratory ABSTRACT Thermodynamic values can be determined using the Vant Hoff isochore method. This method entails the use of equilibrium systems to determine the change in enthalpy of the solution‚ which can b related to the change in internal energy of the solution.

Proposal for a Backup Solution Working as a volunteer for a small non-profit organization‚ I have been asked find a suitable backup solution for our environment. The plan should allow‚ not only the backup of critical data‚ but also the ease of moving the data offsite in the event of a disaster. Requirement The organization consists of twelve workstations‚ one being a laptop‚ all less then three years old. Each workstation runs Windows XP and is connected through a LAN and to the internet
