5A sensor samples a water level of 74.78 cm, which is quantised to 70 cm. What is the percentage error?

6Noise in a sensor signal is

7A temperature sensor reads 4 °C in melting ice (0 °C) and 96 °C in boiling water (100 °C). If its response is a straight line, what is the true temperature when it reads 50 °C?
