The just-in-time (JIT) movement has long argued that firms should:

• Maximize their process flexibility so that ordering costs are minimal.
• Stabilize demand levels.
• Shrink lead times as much as possible.
• Assign much higher holding costs to inventory than has traditionally been the case.

Using the economic order quantity (EOQ) and reorder point (ROP) formulas, explain how such efforts would be consistent with JIT's push for lower inventory levels

You and a friend are rolling a set of 8 dice. The game works such that if a die shows the values 1, 2, 3, or 4 you will get a point for that die. Each die that shows 5 or 6 your friend will get a point for. Construct a probability model for a single roll of the dice then answer the following.

Step 2 of 5: What is the probability that your friend will score 2 points?

Step 3 of 5:

What is the probability you score 4 or more points in this round?

Step 4 of 5:

If we play a second round of this game, what is the probability that you will have exactly 6 points at the end of the second round?

Complete the following method in java:

public static List<Integer> runningMedianOfThree(List items)

Create and return a new List<Integer> instance (of any subtype of List of your choice) whose first two elements are the same as that of original items, after which each element equals the median of the three elements in the original list ending in that position. For example, when called with a list that prints out as [5, 2, 9, 1, 7, 4, 6, 3, 8], this method would return an object of type List<Integer> that prints out as [5, 2, 5, 2, 7, 4, 6, 4, 6].

The demographic transition:The 4 stages of this transition are very important to know and understand.

a For each stage below explain what is occurring with birth and death rates AND state if population is stable, growing or declining. (3 points)

• Stage 1
• Stage 2
• Stage 3
• Stage 4

b) Imagine you are a political leader in a country that is in stage 2 of the demographic transition and you are developing a plan to move your country through stages 2 and 3 to reach stage 4 as quickly as possible. What would be some specific methods you would advocate or laws you would pass to reach this goal. (1pt)

write a program on c++ that outputs a calendar for a given month in a given year, given the day of the week on which the 1st of the month was. The information in numeric format (months are: 1=Januay, 2=February 3=March, 4= April, 5= May, 6= June, 7= July... etc days are 1=Sunday, 2=Monday, 3= Tuesday, 4= Wednesday, 5= Thursday, 6= Friday and 7= Saturday ). The program output that month’s calendar, followed by a sentence indicating on which day the month ended.

ex: if the user enters for year: 2020 for month: 2 for day of week that 1st month fell: 7

The outcome should look like

Here is the calendar for February of 2020

Sun Mon Tue Wed Thu Fri Sat
------------------------------------------
                                                  1  
   2     3       4     5      6 7     8
   9    10     11   12    13    14   15
16   17     18   19    20 21   22
23   24     25   26    27    28   29
The month ends on a Saturday.

For the month of February, the program has to decide if the year is leap (29 days) or not.

At 500 °C, cyclopropane (C3H6) rearranges to propene (CH3CH=CH2):

C3H6 (g) ------> CH3CH=CH2 (g)

The reaction is first order and the rate constant is 6.7 x 10-4 s-1. (a) What is the rate law for the reaction, and; (b) if the initial concentration of C3H6 is 0.100 M, what is the concentration of cyclopropane of after 20 min?

3. Butadiene (C4H6) reacts with itself at 250 °C to form a dimer with the formula C8H12.

2 C4H6 (g) ----> C₈H₁₂ (l)

The reaction is second order in C4H6. (a) What is the rate law for the reaction, and; (b) if the rate constant is 4.0 x 10-2 M-1.s-1, and the initial concentration of C₄H₆ is 0.200 M, how long will it take for the concentration of C4H6 to reach 0.04 M?

4.         a) In Q. 2 above what is the half life for the reaction and what is concentration of C₃H₆ after 3 half-lives b) In Q. 3 above how long are the first and second half-lives?

help with question 2, 3 and 4. i already did them, i just want to compared answers so please show steps.
