What is the definition of a number line?

Back

A number line is a straight line that represents numbers as points at equal intervals, allowing for the visualization of numerical relationships.

Front

What does it mean for a point to be the opposite of another point on a number line?

Back

The opposite of a point P on a number line is the point that is the same distance from zero but in the opposite direction.

Front

How do you determine the location of a point on a number line given its coordinate?

Back

The location of a point on a number line is determined by its coordinate, which indicates its distance from zero.

Front

What is the formula to find the total time taken if a distance is traveled at a constant rate?

Back

Total time = Distance / Rate.

Front

If a train travels 1/5 of a distance in 3/4 hour, how do you find the time to travel the entire distance?

Back

Multiply the time taken for 1/5 of the distance by 5 to find the total time for the entire distance.

Front

What is a scale in the context of maps?

Back

A scale is a ratio that represents the relationship between a distance on the map and the actual distance it represents in reality.

Front

How do you convert a distance on a map to the actual distance using the scale?

Back

Use the formula: Actual distance = Distance on map × Scale factor.

Front

What is the significance of assigning digits to sections of a wheel in a simulation?

Back

Assigning digits allows for the representation of different outcomes in a simulation, facilitating the study of probabilities.

Front

What does it mean for a student's claim about point locations to be correct or incorrect?

Back

A claim is correct if it accurately reflects the relative positions of points on the number line; otherwise, it is incorrect.

Front

How can you express a fraction as a decimal?

Back

Divide the numerator by the denominator to convert a fraction into its decimal form.
