A chemical company sells a specialized industrial lubricant in 20 liter containers. A random sample of the latest production lot shows the contents of 10 containers to be 20.3, 19.91, 19.98, 19.69, 19.54, 20.51, 20.36, 20.46, 19.68, and 20.56 liters. Find the standard deviation of the sampled containers’ contents. A. σ=0.36
B. σ=0.55
C. σ=0.53
D. σ=0.42

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.

The difference of two numbers is 40. find the numbers if 0.3 parts of one number is equal to 37.5% of the other one.
