Question
A records voltages from 0 volts to 20 volts. If the average value for three readings on the meter was 16 volts, then what the smallest number possible reading, in volts?
Answers
Steve
since the largest reading is 20, you have
x+20+20 = 3*16
x = 8
for the smallest.
x+20+20 = 3*16
x = 8
for the smallest.
