Be aware that these packages are available in different configurations. Some are individual resistors with both leads brought out or they are available with one side of the resistors in common to a single pin. This helps when you are planning to use them for pullups on digital inputs. In analog circuits, as Ken has pointed out, resistor groups can be optimized for better precision than 1% and are often used when designing op amp circuits that require tight gain matching and the best common mode rejection, differential amplifier charachteristics and temperature stability. The Digikey catalog has some of the wiring styles available and often will link to manufacturers websites for further details.
