Here is how we think about it: It is $100 for the first 10 feet. After that it is $25 for each additional 10 feet. This tells us that it is arithmetic sequence because we are multiplying. N= the number of terms altogether N= 8 D= the common difference D=25 A1= the first term A1= 100 An= the second term An= a8 Next, we need to compute what a8 is. An= a8+ (n-1) d A8= 100+ (8-1)25 A8=100+7(25) A8=100+200 A8=300 Now that we know what A8 is, we need to know what the sum of the sequence is from A1 to A8.

The following costs were incurred in the first processing department during the month: The ending inventory was 90% complete with respect to materials and 45% complete with respect to conversion costs. Note: Your answers may differ from those offered below due to rounding error. In all cases, select the answer that is the closest to the answer you computed. To reduce rounding error, carry out all computations to at least three decimal places. 8. award: 1 out of 1.00 point How many units are in ending work in process inventory in the first processing department at the end of the month?
If they want to cut this by a factor of three to get it down to $4000, they need to multiply the sample size by 3^2=9, and get a sample size of 25×9= 225. Here is how we can calculate it more directly. We want ME = 4000, and we know ME = 2×SE. Therefore, SE = ME/2 =2000, and also, SE = SD/Square root of sample size. So, 2000 = 30000/Square root of sample size.
FI 515 Course Project a) The net cost of the spectrometer would include the original cost of the equipment, the modification costs and the increase in working capital due to having the equipment. Therefore, the net cost would be the $70,000 base costs, plus the $15,000 in modification costs and the $4,000 in capital, which equals $89,000. b) To find the operating cash flows for the three years, we have to find the cost savings after taxes and add the tax of depreciation. To find the cost savings, we have to take the $25,000 that is expected to be saved and reduce it based on a tax of 40%, or $25,000(1-.4), which equals $15,000. The tax on depreciation requires several steps to calculate.
So, if we take random values for r2 between 0 and 1 then we will get different values of time intervals in weeks between successive breakdowns. 3. Lost revenue It is given that they charge $0.10 per copy and number of copies sold in one day follows a uniform probability distribution between 2000 and 8000 copies. Therefore, if we chose a random variable r3 whose value is in between 2000 and 8000 then the lost revenue will be 0.1×r3×repair time. By putting different values for r3, we can get a number of lost revenues by simulation method.

b. One inch on this map equals exactly __24,000___ inches in real life. c. One inch on this map equals exactly _0.3__ mile(s) in real life, so we can say that 1 inch on the map equals approximately 1/3 mi on the ground. (Lab Man) 3 6. Review how the location of point x in Fig.9.5 in 9th ed’n was determined using PLS shorthand (see caption for Figure 9.5). Then, determine the location of point V in the Figure below using PLS shorthand.
