Alast-mile delivery service is looking into increasing capacity by purchasing new delivery vans. two vans are being considered. van a costs $50,000 with a variable cost of $12.00 per average delivery, all inclusive of gasoline insurance, etc. van b costs $70,000 with a variable cost of $11.00 per average delivery. the company is also considering a courier service which requires a $60,000 non-refundable joiner fee and a variable cost of $13.00 per average delivery. last but not least the company is also considering a new drone delivery option that requires an investment in infrastructure of $100,000 and a delivery cost of $15.00 per delivery, but costs are expected to drop sharply in the foreseeable future. a. what of the following is not true? select in the long run, option b with its $11.00 variable cost is the best option the drone option should be chosen because it is the least expensive in terms of both fixed and variable cost. option a requires the smallest initial cash outlay, followed by using the courier service, followed by option b. there is no point of indifference/break even between option a and using the courier service b. volumes above. select ] is preferred at volumes below while is preferred at b and 30,000, a and 20,000 b and 5,000, c and 5,000 c is always preferred to a at every volume a and 20,000, b and 20,000 c. if the average sales revenue generated by the delivery service $15.00 per delivery, but customers are willing to pay $20.00 for the novelty of drone delivery, what is the breakeven in units for each option? select ] 16,667 for option a and 20,000 for drone option option a and drone delivery do not crossover 20,000 for option a and 16,667 for drone option option a is always better than drone delivery

You use a p-20 micropipette to transfer 20 µl of water to a microcentrifuge tube. next, you use a p-200 to add 200 µl of dye to the same tube. finally, you use a p-1000 set to 220 µl to remove the mixture from the tube. you see there is a 1 cm air space at the end of your p-1000 pipette tip after all the liquid has been withdrawn from the tube. propose two specific reasons this could occur and explain how you could test each of these possibilities. "specific" means something more than just "i must have made a mistake." how will you distinguish between user error (something you did wrong) and instrument error (something that’s wrong with the micropipette)?
