Step-by-step explanation:
This equation represents the data:
2.5(12.75x + 24.50) = 188.75
31.875x +61.25 = 188.75 . . . . . eliminate parentheses
31.875x = 127.50 . . . . . . . . subtract 61.25
x = 4 . . . . . . . . . . . . . . . . . . . divide by 31.875

Answer:
Attached is the profit distribution plotted on the chart and also the detailed solution using excel
Step-by-step explanation:
To solve this problem we have to
- create a column for number of counts ( 1,2,3........1000) bids
- create a column for the cost to be incurred which is mostly dependent on the random number generated. the formula for that using excel is; 9000+ rand()*(11000-9000) for uniform distribution between the numbers
- Four(4) more columns are generated for bids of competitors by using the formula: 10000+rand()*(3*10000-10000) this because the bids that will be submitted by others bidders will vary uniformly between her mean cost and 3 times her mean cost
- Condition is checked to see if the lowest bid is. =IF(MIN(the 4 bids)>14000,1,0)
- Next the same process is carried out for 13000 and 15000
- The probability of winning is calculated in excel using this formula =Countif(value of step 4 for all the rows,1)/1000
Answer: 1
B is the center of a circle of radius 1. A and C are on the circle 100 degrees apart. So arc AC is 100 degrees. Arc AC the long way around is 360-100=260 degrees. That means any point D on arc AC will subtend a 130 degree angle. BD is a radius for all of those, and the radius is 1.
