Difference in frequency of first two=600-560=40
And difference in relative frequency of first two= .30-0.28=0.2
Difference in relative frequency in last two=0.22-0.20=0.2
Hence difference in frequency in last 2 should be 40
Hemce frequency =400+40=440
hence option a is correct

6. Costs in the short run versus the long run Ike's Bikes is a major manufacturer of bicycles. Currently, the company produces bikes using only one factory. However, it is considering expanding production to two or even three factories. The following table shows the company's short-run average cost each month for various levels of production if it uses one, two, or three factories. (Note: equals the total quantity of bikes produced by all factories.) Average Cost Dollars per bike) Q=200...

Lab 7 7. In this experiment, DCPIP was used to indirectly measure photosynthetic rate. If you were asked to design an experiment so that photosynthesis could be measured directly, what factors might you measure? 8. Compare your results for the absorption spectrum and the action spectrum. Explain any discrepancies between the wavelengths of light that are absorbed maximally and those wavelengths that cause the greatest photosynthetic activity. (Note that the wavelengths of light transmitted by each coloured filter can be...

174 2 combustor , =1500 K Problem 2 (22 pts): Brayton cycle and entropy calculations An open Brayton cycle is used to generate electricity. Air enters the isentropic compressor at T1 = 300 K and P1 = 100 kPa with a mass flow rate m = 1.5 kg/s. The combustor can be modeled as a constant-pressure heat exchanger, supplying 1540 kW of thermal power to the air from a thermal reservoir (Th = 1750 K). Air enters the isentropic turbine...
