In a precision machining shop, a part's allowable dimension error, $x$, must fall within a strict tolerance defined by the inequality $|x| < 1$. Recalling the translation rule for 'less than' absolute value inequalities, which interval notation represents all acceptable error values?

In a quality control department, a technician uses the inequality $|w| < 9$ to describe the allowable weight variance of a product. This inequality means that the variance $w$ is restricted to values strictly between ${}-9$ and ${}9$.

Documenting Laboratory Tolerance

In industrial quality control, technicians must be able to convert between different mathematical representations of tolerance limits. Match each descriptive term with its correct equivalent form for the standards $|x| < 9$ and $|x| < 1$.

A Quality Control Technician is training on how to report measurement deviations in a facility log. To document the tolerance defined by $|x| < 9$, the technician must follow a specific mathematical procedure to reach the final interval notation. Arrange the following steps in the correct order.

A calibration technician in an electronics manufacturing plant is testing the output signal deviation, $x$ (in milliamperes), of a precision temperature sensor. The quality assurance manual states that the sensor's deviation must satisfy the absolute value inequality $|x| < 1$.

To document this quality standard in the laboratory log, the technician needs to record the allowable deviation range in standard interval notation. Recall the translation rule for absolute value inequalities featuring a 'less than' sign.

The acceptable range of deviation, written in standard interval notation, is ____. (Format your answer using parentheses, like (a, b), with a single space after the comma.)
