I have been reading many answered problems on this website earlier today and I have been doing some recent research on the topic of "zero" and "nothing". I was trying to relate this controversial topic about "nothing" and the number zero itself to Pythagoras and possibly the magic triangles and squares... I have been trying for the past few hours but nothing comes to mind. The value of zero in mathematics it much different to the meaning of "nothing" itself in physiology and physics so I thought it could become very interesting to relate the Zero and this whole topic about the DIFFERENCE BETWEEN NOTHING AND ZERO to the history and Pythagoras.

Solve (D2-3D+2)y =x(x+4) and show that its general solution is given by y=Aex + Be2x +(x2/2) + (7x/2) + (19/4)

My work :

auxiliary eqn , m2 - 3m + 2= 0 m=1 , m=2

Reduced eqn : yn = Aex + Be2x

P.I. = 1/f(D)F(x) = (1/(D2-3D+2))(x(x+4))

P.I. = [(x2+4x) + ( (1/2)( 2- 3(2x) - 3(4) ) ) + (1/4)(92) )

P.I. = x2 + (4x/2) - (6x/4) - (5/2) + (18/4)

P.I. =(x2/2) + x + 8/4

General solution : y= Aex + Be2x + (x2/2) + x + 8/4

Could anyone point out my mistakes?

Jim Sellers considers producing a new type of electric razor for men. If the market is favorable, he would get a return of 60000. Since Ron Bush is a good friend of Jim Sellers, Jim is considering the possibility of using Bush Marketing Research Company to gather additional information about the razor market. Bush has suggested that Jim either use a survey, or a pilot study to test the market. The survey is a sophisticated questionnaire administered to a test market, and costs 20000. Ron Bush has proposed Jim to conduct either the survey, or the pilot study before making any decision regarding the production of the new razor. Jim is however not convinced that the contribution of the survey, or that of the pilot study, is worth its cost.

Ron Bush has proposed Jim to conduct either the survey, or the pilot study before making any decision regarding the production of the new razor. Jim is however not convinced that the contribution of the survey, or that of the pilot study, is worth its cost. Jim estimates that the unconditional probability of a successful market is 0.5. Furthermore, the probability of a favorable survey result given a favorable market for razors is 0.7 and the probability of a favorable survey result given an unsuccessful market for razors is 0.2. In addition, the probability of an unfavorable pilot study result given an unfavorable market is 0.9, and the probability of an unfavorable pilot study result given a favorable market for razors is 0.2. Jim wants to use these probability estimates to decide whether to do the survey, or the pilot study, or none.

A) Using PrecisionTree, draw a decision tree to solve Jims problem. Explain how you have calculated all the probabilities that you report on the tree. Define clearly each decision node, event node, decision that you can take, and possible outcome for the random variables.

Let: . FS denote the “favorable survey" outcome . US denote the “unfavorable survey" outcome . FP denote the “favorable pilot study" outcome . UP denote the “unfavorable pilot study" outcome . F denote the “favorable market" scenario . U denote the “unfavorable market" scenario

B) What is the best decision for Jim amongst opting for survey or pilot study or none? Include the decision tree in your analysis/report.

C) Suppose that the cost of the pilot study can be cut down to $15,000. Does it affect Jims best decision?

This question can be solved using The Singapore maths bar method

Ron Bush has suggested that it would be a good idea for Jim to conduct either the survey or the pilot before Jim makes the decision concerning whether to produce the new razor. ButJim is not sure if the value of the survey or the pilot is worththe cost. Jim estimates that the probability of a successful market without performing a survey or pilot study is0.5. Furthermore, the probability of a favorable survey result given a favorable market for razors is 0.7, and the probability of a favorable survey result given an unsuccessful market for razors is 0.2. In addition, the probability of an unfavorable pilot study given an unfavorable market is 0.9, and the probability of ann unsuccessful pilot study result given a favorable market for razors is 0.2.

Draw the decision tree for this problem without the probability values. Computer the revised probabilities needed to complete the decision, and place these values in the decision tree. What is the best decision for Jim? Use Expected MonetaryValue (EMV) as the decision criterion.

Hi, I need a bit of help on how to solve the following. y = -4x + 4 y = x2 -6x - 8 I have tried to substitute equation one into equation two ( RHS must be equal) to give -4x + 4 = x2 -6x -8 I have then added all like terms to give but im then stuck and I think i have got the method wrong. Bit confused due to x2 and y = as I thought i did understand how to solve these so im now annoyed. x2 -10x -4 Any help on how to solve this would be helpful. Thanks

Hey guys 🙂 I'm kinda stuck on this question.. so i have to sketch the graph: y=(x2-4)/(x2+4x+6) so I know you have to find the vertical asymptote which doesn't exist by the way and the horizontal asymptote is y=0. the x-intercept=2, y-intercept=-2/3. Ok, now I need to draw the graph now but i don't really know how.

I'm not sure how answers are marked in A level Mathematics exams (if it counts, I'm sitting for the CIE board) but when I am doing practice questions based on a book, sometimes my answer may differ by a few hundredths or tenths (usually the third significant figure). When this happens, I usually assume that my calculation is correct and that the difference simply happens because of a choice I use to use or not use the correct form, not the one rounded off to 3 s.f. Would my marks be affected by these differences in an exam and if they do, when do I know whether I should use the rounded off figure or the exact form?

For instance in the work I've recently done, the question comes in 2 parts, the first is that I need to find the area of the sector and the second is the area of the chord of said sector. What I did was subtract the area of triangle from my previous answer but my answer was off by 2 hundredth. I did the calculation again using the correct form of the sector, not the one rounded to 3 s.f. and got the answer written in the answer booklet.

Would my answer be considered correct?

A student measured the data in the tables below by recording the time, t, it took two different cylinders (one solid and one hollow) with the same dimensions to roll, from rest, down a slope for a fixed distance.

Theory suggests that the hollow cylinder should take longer to travel the same distance as the solid cylinder. Hollow Cylinder times, t/s Solid Cylinder times, t/s 2.08 2.03 1.88 1.88 2.07 2.07 1.79 1.87 2.05 2.01 1.80 1.90 2.04 2.16 1.85 1.78 2.03 2.03 1.90 1.81 2.12 2.01 1.76 1.74 2.06 2.05 1.62 1.73 2.07 2.08 1.72 1.79 1.97 2.11 1.77 1.87 1.99 2.12 1.77 1.82 2.10 2.00 1.81 1.79 2.06 2.01 1.77 1.84 2.07 2.02 1.81 1.83 2.06 1.99 1.84 1.77 2.13 2.07 1.86 1.80 1.98 2.10 1.80 1.73 2.04 2.02 1.78 1.77 2.05 2.11 1.76 1.84 2.03 2.08 1.82 1.95 2.02 2.08 1.81 1.87 2.00 2.07 1.67 1.79 1.97 2.12 1.84 1.89 2.10 2.03 1.74 1.87

To analyse the data it is suggested to the student that she groups the data and produces a histogram for each cylinder showing the distribution of rolling times. The student consults her lecturer who suggests the following class intervals, where t is the rolling time in seconds: A B C 1.50

a.The student decides to use the class intervals shown in column C in the table, explain why this is an appropriate choice for the data from this experiment.

1. Construct histograms for the experimental data using the class intervals shown in column C of the table above.

2. Calculate the mean rolling time for each of the cylinders.

3. Produce a spreadsheet to calculate the standard deviation in the rolling time for each cylinder – the spreadsheet table should show the additional columns required and a print out including the formulae you have used in each cell is required.

4. Use the “Comparison of Means Test” (Shown below) to determine whether there is significant difference in the rolling time between the two cylinders.

Comparison of means test (i) Calculate the difference between the mean values of each data set.

(ii) Calculate the “Standard error of the difference” using the formula below:

Standard error of difference = √((S1/n1)+ ) (S2/n2) (the frist one is S1 2 and next is S2 2 )

Where: s1 is the standard deviation of data set 1, n1 is the number of measurements in data set 1, s2 is the standard deviation of data set 2 and n2 is the number of measurements in data set 2.

If the difference between the mean values of each data set is greater than twice the standard error of the difference then you can be 95% confident that there is a significant difference between the two sets of data i.e. whatever has been changed between one data set and the other has influenced the results.
