His question concerns bit strings of length six. These bit strings can be divided up into four types depending on their initial and terminal bit. Thus the types are: 00, 01, 10, 11. How many bit strings of length six must you select before you are sure to have at least 55 that are of the same type? (Assume that when you select bit strings you always select different ones from ones you have already selected.)

Alook-up table used to convert pixel values to output values on a monitor. essentially, all pixels with a value of 190 or above are shown as white (i.e. 255), and all values with a value of 63 or less are shown as black (i.e. 0). in between the pixels are scaled so that a pixel with a value p is converted to a pixel of value 2/127 −+3969). if a pixel has a value of 170 originally, what value will be used to display the pixel on the monitor? if a value of 110 is used to display the pixel on the monitor, what was the original value of the pixel?

The guy wire bd exerts on the telephone pole ac a force p directed along bd. knowing the p must have a 720-n component perpendicular to the pole ac, determine the magnitude of force p and its component along line ac.
