An archaeologist finds some ancient jewelry made from bone. The jewelry has a carbon mass of 303 g (HINT: Assume all the carbon is 12C and determine the number of atoms) and careful measurements show that the remaining 14C has a current decay rate of 14 decays/s. Determine the age of the bone (and presumably the jewelry). Remember, the ratio of 14C to 12C when the animal died was 1.3×10-12 & the half-life of 14C is 5730 y. age of...

Radiocarbon or 14C is a widely used tracer for groundwater movement for up to 30,000 years. 14C can be used to estimate recharge rates and horizontal flow rates important for water related policy decisions. 14C has a half-life of 5730 years and the ratio of 14C to all C from biological material is 1.3 × 10−12. The atomic mass of carbon is 12.0107 g/mol. Your sample is 0.29 g of carbon. The activity of this sample, due to presence of...

Goetz Company manufactures wallets from fabric. In 2016, Goetz made 2,700,000 wallets using 1,875,000 yards of fabric. In 2016, Goetz has capacity to make 3,600,000 wallets and incurs a cost of $12,600,000 for this capacity. In 2017, Goetz plans to make 3,348,000 wallets, make fabric use more efficient, and reduce capacity. Suppose that in 2017 Goetz makes 3,348,000 wallets, uses 2,160,000 yards of fabric, and reduces capacity to 3,100,000 wallets at a cost of $8,990,000. Read the Fequirements. Requirement 1....

A streaming music site changed its format to focus on previously unreleased music from rising artists. The site manager now wants to determine whether the number of unique listeners per day has changed. Before the change in format, the site averaged 131,520 unique listeners per day. Now, beginning three months after the format change, the site manager takes a random sample of 30 days and finds that the site has an average of 124,247 unique listeners per day. The manager...
