Identify a method whereby a random sample can be selected from the population.A shipment of 2000 radios has arrived at electronic City's warehouse. The warehouse foreman wants to determine the rate of defects. He will randomly sample 20 radios and check for defects. The serial numbers of the radios range from 2010 to 4010.
A. Open a carton and check the first 20 radios. B. Use a table of random numbers to generate 20 random numbers between 2010 and 4010 and use these numbers to identify the radios to be included in the sample. C. Choose the 20 radios that look the most damaged.

Solve the problem.Assuming equal costs, when warehouse workers use hand trucks to load a trailer, it costs the management for labor for each trailer. After management purchases a forklift for
, it costs only
for labor to load each trailer. Write the equation that models the cost, C(n), of loading n trailers with a hand truck, and the cost, C(n), of loading n trailers with the forklift. Then, solve this system using an algebraic approach.
A. Cost using hand trucks: C(n) = 50n Cost using forklift: C(n) = 2100 + 25n n = 82 B. Cost using hand trucks: C(n) = 25n Cost using forklift: C(n) = 2100 + 50n n = 82 C. Cost using hand trucks: C(n) = 25n Cost using forklift: C(n) = 2100 + 50n n = 84 D. Cost using hand trucks: C(n) = 50n Cost using forklift: C(n) = 2100 + 25n n = 84
