A logistics company defines a 'lightweight' shipping category for any package with a weight, x, strictly less than 2.5 kilograms. Which interval notation correctly represents this weight category?

An environmental safety officer is monitoring the pressure in a pipe. The pressure deviation p must be less than 2.5 units (p < 2.5). Which interval notation correctly represents the range of pressure deviations that are strictly less than 2.5?

In a professional quality control laboratory, technicians define operational safety ranges using inequalities. Match each inequality representing a threshold to its corresponding interval notation.

In an industrial refrigeration unit, a technician monitors the internal temperature $x$ to ensure it stays greater than or equal to $-3$ degrees Celsius ($x \geq -3$). True or False: The correct interval notation for this temperature range is $(-3, \infty)$.

A laboratory technician is documenting a safety threshold for a chemical reaction where the pressure deviation $x$ must be less than or equal to $-\frac{3}{5}$ ($x \leq -\frac{3}{5}$). Arrange the following steps in the correct order to represent this threshold on a number line and in interval notation.

Reporting Quality Control Thresholds

An environmental safety officer is recording a pressure tolerance limit for an underwater sensor. The limit is defined by the inequality $x \leq -\frac{3}{5}$. To ensure the data is compatible with the reporting software, the officer must record this limit using interval notation as ____.

Standardizing Technical Safety Thresholds

Laboratory Safety and Pressure Thresholds

An Environmental Health and Safety (EHS) officer is updating a safety training poster that shows the graphical range for a temperature threshold defined by the inequality $x \geq -3$. Which combination of endpoint symbol and shading direction must the officer use on the number line to correctly represent this threshold?

Graphing $x > 2$, $x \leq -1.5$, and $x \geq \frac{3}{4}$ and Writing in Interval Notation
