You will perform a simple experiment to examine how the volume of a three-dimensional object changes if you slant its vertical axis. You can perform this activity using a stack of identical coins, CDs, or any available set of identical disk-shaped objects. If you cannot locate a set of disk-shaped objects, go to oblique cylinders to simulate the experiment online. Scroll down to the Volume section. Begin by stacking the disks one on top of the other so they create an upright stack. That is, the disks should form a right cylinder.

Question 1
Think about the volume of the stack. By definition, what is the volume of the stack equal to? Express you answer in words instead of numbers.

Fran would like to estimate the mean amount of time it takes people in her town to travel to work. the town's population is 150,000 and about 90,000 of those are working adults. which statements are true? select each correct answer. there is no way to infer the value of the mean. she must collect data for all 90,000 working adults and calculate the mean. a larger sample of working adults will provide a better estimate of the true mean than a smaller sample. the population of working adults is too large for using a sample to estimate the mean of the entire group. if she takes a random sample of the population of working adults in her town, the mean for that group is likely close to the mean for the entire group.

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)
