The correct answer for the question that is being presented above is this one: "3/8" A traffic light near a museum is green for 30 seconds, yellow for 5 seconds, and red for 15 seconds. <span>If 8 vehicles approach the signal, the probability that 3 of them are stopped by the red light is 3/8</span>
Definitely cell phone reception! However books could be argued for since they also are a good more than a necessity. However the last 2 i believe would be classified more as necessities than goods.
~Hope this helps!~
Explanation:
The frictional resistance of the various pipes are given by the
K value in the table which may be used with the formula
hf = KQ2
to relate the magnitude of head loss hf in the pipeline
to the volumetric flow rate, Q. Water is drawn at the constant flow
rates from the network at nodes C and D. The static heads
(elevation + pressure head) at nodes B, C and D are 100m, 65m
and 61m respectively above the local datum. Calculate the
discharges at C and D and the water level in reservoir A. (The
data has been added to the diagram to aid the solution)
Use no more than 3 iterations and 3 significant figures.
