Solve the given system of differential equations by systematic elimination.
| (D2 − 1)x | − | y | = | 0 |
| (D − 1)x | + | Dy | = | 0 |
I had this as my answer and webassign rejected it:
(x(t), y(t)) = c_1e^t+e^{-\left(\frac{t}{2}\right)}\left(c_2\cos \left(\frac{\sqrt{3}}{2}t\right)+c_3\sin \left(\frac{\sqrt{3}}{2}t\right)\right),e^{-\left(\frac{t}{2}\right)}\left(\left(-\frac{3}{2}c_2-\frac{3\sqrt{3}.}{4}c_3\right)\cos \left(\frac{\sqrt{3}}{2}t\right)+\left(\frac{-3}{2}c_3+\frac{3\sqrt{3}}{4}c_2\right)\sin \left(\frac{\sqrt{3}}{2}t\right)\right)

Let X equal the number of telephone calls per hour that are received by 911 between midnight and noon. For a two-day period, researchers recorded the number of calls received in each hour. Those values were: 0, 1, 1, 1, 0, 1, 2, 1, 4, 1, 2, 3, 0, 3, 0, 1, 0, 1, 1, 2, 3, 0, 2, 2.
This problem is about deciding if it looks like the Poisson distribution might be an appropriate model for X.
(a) First, recall that, for a Poisson distribution, the mean and the variance are the same. Calculate the mean and variance for this dataset. Are they approximately equal? What does this tell you about the plausibility modeling this data as coming from a Poisson distribution?
(b) Next, compare the numbers of calls that arrived with what you would expect from a Poisson distribution. Specifically, for each value 0, 1, 2, 4, and “5 or more”, calculate the probability that a Poisson distribution will yield that value. Use the Poisson distribution with µ equal to the mean of your dataset. Then compare this to the proportion of hours in the dataset that had that many calls. Please give me this comparison in two forms: A table and a graph. Use some of your own judgement on this one. In the end, comment on whether you believe the data follows a Poisson distribution.

Sager Products has been in the business of manufacturing and marketing toys for toddlers for the past two decades. Jim Sager, president of the firm, is considering the development of a new manufacturing line to allow it to produce high-quality plastic toys at reasonable prices. The development process is long and complex. Jim estimates that there are five phases involved and multiple activities for each phase.
Phase 1 of the development process involves the completion of four activities. These activities have no immediate predecessors. Activity A has an optimistic completion time of 2 weeks, a probable completion time of 3 weeks, and a pessimistic completion time of 4 weeks. Activity B has estimated completion times of 5, 6, and 8 weeks; these represent optimistic, probable, and pessimistic time estimates. Similarly, activity C has estimated completion times of 1 week, 1 week, and 2 weeks; and activity D has expected completion times of 8 weeks, 9 weeks, and 11 weeks.
Phase 2 involves six separate activities. Activity E has activity A as an immediate predecessor. Time estimates are 1 week, 1 week, and 4 weeks. Activity F and activity G both have activity B as their immediate predecessor. For activity F, the time estimates are 3 weeks, 3 weeks, and 4 weeks. For activity G, the time estimates are 1 week, 2 weeks, and 2 weeks. The only immediate predecessor for activity H is activity C. Time estimates for activity H are 5 weeks, 5 weeks, and 6 weeks. Activity D must be performed before activity I and activity J can be started. Activity I has estimated completion times of 9 weeks, 10 weeks, and 11 weeks. Activity J has estimated completion times of 1 week, 2 weeks, and 2 weeks.
Phase 3 is the most difficult and complex of the entire development project. It also consists of six separate activities. Activity K has three time estimates of 2 weeks, 2 weeks, and 3 weeks. The immediate predecessor for this activity is activity E. The immediate predecessor for activity L is activity F. The time estimates for activity L are 3 weeks, 4 weeks, and 6 weeks. Activity M has 2 weeks, 2 weeks, and 4 weeks for the estimates of the optimistic, probable and pessimistic time estimates. The immediate predecessor for activity M is activity G. Activities N and O both have activity I as their immediate predecessor. Activity N has 8 weeks, 9 weeks, and 11 weeks for its three time estimates. Activity O has 1 week, 1 week, and 3 weeks as its time estimates. Finally, activity P has time estimates of 4 weeks, 4 weeks, and 8 weeks. Activity J is its only immediate predecessor.
Phase 4 involves five activities. Activity Q requires activity K to be completed before it can be started. The three time estimates for activity Q are 6 weeks, 6 weeks, and 7 weeks. Activity R requires that both activity L and activity M be completed first. The three time estimates for activity R are 1, 2, and 4 weeks. Activity S requires activity N to be completed first. Its time estimates are 6 weeks, 6 weeks, and 7 weeks. Activity T requires that activity O be completed. The time estimates for activity T are 3 weeks, 3 weeks, and 4 weeks. The final activity for phase 4 is activity U. The time estimates for this activity are 1 week, 2 weeks, and 3 weeks. Activity P must be completed before activity U can be started.
Phase 5 is the final phase of the development project. It consists of only two activities. Activity V requires that activity Q and activity R be completed before it can be started. Time estimates for this activity are 9 weeks, 10 weeks, and 11 weeks. Activity W is the final activity of the process. It requires three activities to be completed before it can be started. These are activities S, T, and U. The estimated completion times for activity W are 2 weeks, 4 weeks, and 5 weeks.

In FCC iron, carbon atoms are located at octahedral sites at the centre of each edge of the unit cell (1/2, 0, 0) and at the centre of the unit cell (1/2, 1/2, 1/2). In BCC iron, carbon atoms enter tetrahedral sites, such as (1/4, 1/2, 0). The lattice parameter is 0.3571nm for FCC iron and 0.2866nm for BCC iron. Assume that carbon atoms have a radius of 0.071nm.
(a) Would we expect a greater distortion of the crystal by an interstitial carbon in FCC or BCC iron?
(b) How is the distortion in FCC and BCC related to solubility of the interstitial carbon? Show your all work of calculation for a credit.

C++ code please:
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates how much to multiply the array by. Finally, print out the entire array with each element multiplied by the last input.
Assume that the list will always contain less than 20 integers.
Ex: If the input is
4 4 8 -4 12 -1
the output is
-4 -8 4 -12
Ex: If the input is
7 0 1 2 3 4 5 6 3
the output is
0 3 6 9 12 15 18
