Question 1090994: Tolerance in engineering is an allowance made for imperfections in a manufactured object. The manufacturer of an oven specifies a temperature tolerance of ±15oF. This means that the temperature inside the oven will be within 15oF of the temperature that it is set on. Write an absolute value expression to represent the maximum and minimum temperatures inside the oven when the thermostat is set on 400oF. (o means degrees)
So I know that 15 is the absolute value but I have zero clue how to make it into an expression.
Please help, thanks. Answer by ikleyn(52834) (Show Source):
This absolute value expression to represent the maximum and minimum temperatures inside the oven when the thermostat is set on 400°F is
|T - 400| < 15, (1)
where T is the temperature in the thermostat, when it is set on 400°F.
The inequality (1) has the solutions = 385°F <= T <= 415°F = .
