(Round to the nearest dollar.) (a) Straight-line. 279,000-15,000 = $264,000 / 10 yrs = $26,400 (b) Units-of-output. 264,000 / 240,000 units = $1.10 25,500 units x 1.10 = $28,050 (c) Working hours. 264,000 / 25,000 hrs = $10.56 2650 hrs x 10.56 = $27,984 (d) Sum-of-the-years’-digits.
Problem #35 • This sequence is arithmetic • The cost to build the tower is $1800. STEPS/CALCULTATIONS YOU PERFORMED TO REACH THE ANSWER: The common difference in this sequence is $25, thus making it an arithmetic sequence. The formula for finding the final term is an = a1 + (n-1)d. In this problem, n=9 for the 9 sections of 10 foot sections, a1=100 since that is the first term of the sequence, and d=25 for the common difference. An = a1 + (n-1)d A9 = 100 + (9-1)25 A9 = 100 + (8)25 A9 = 100 + 200 A9 = 300 So the final term of the sequence is 300. Now that we know this, we can find the sum of the terms to calculate the final cost.

On page 29 is the explanation of uncertainty. The concept is illustrated in Figure 13 on page 30. I expect your report will include length to 0.1 cm, a whole mm, and to 0.001 m. As an example, a sheet of paper is 21.6 cm, 216 mm, or 0.216 m wide. In each case, the measurement is precise to 1 mm (which is 0.1 cm and 0.001 m). The first degree of uncertainty is at the mm length.
Math 540 Luevirta Hammonds Strayer University October 26, 2011 Days to Repair The days to repair is explained in the table below as follow: P(y) represent the days that is needed to repair the copier after it breaks down. Cumulative represent the increase in value of the probability distribution. Repair Time y represents the days it takes to repair the copier. P(y) Cumulative Repair Time (y) 0.2 .20 1 0.45 .65 2 0.25 0.90 3 0.1 1.00 4 1 2.75 The simulation in column one on the excel spreadsheet with the list of 100 breakdowns in 52 week which represent one year. In column C, RN1 (random numbers) generate numbers between zero and one and represent random numbers
Three exemptions are equal to $11100 (3*3700), so $61000-$11100=$49900. Now we can look up $49900 in 2011 Tax Table for single filler. 3-36.
Week Three Discussion Questions • Can the probability be more than 1 or less than 0? Explain why or why not. According to the Statistics for Business and Economics book, probabilities have to follow two basic rules and one of them is that the number has to be between 0 and 1. Therefore, the probability cannot be more than 1 and less than 0. • Based on the data collected on a typical day, what is the probability that oil change will take 15 minutes or less time?
