3. Jack Watson is wroking in a lab making microchips for computers. he uses a "super tool" that measures the size of a transitor on a microchip by magnifying the transitor to twice its actual size and measuring the magnified size. The actual size of the transitor must be within 4 nanometers of the magnified industry standard. Theindustry standard for the actual size is 80 nanometers. The inequality below models the range of the actual size of the transitor.
4 <or equal to 2(x 80)<4. Which graph correctly represents the range in which the actual transitor size for a particular transitor is within the industry standard ?
