What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots representing the frequency of data points in a dataset. Each dot represents one occurrence of a value.

Front

How do you determine the number of dots in a figure if they increase at a constant rate?

Back

To determine the number of dots in a figure with a constant rate of increase, identify the pattern or formula that describes the increase, then apply it to find the number of dots in the desired figure.

Front

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, expressed as a number between 0 (impossible) and 1 (certain). It can also be expressed as a percentage.

Front

What does it mean for a decimal to terminate?

Back

A decimal is said to terminate if it has a finite number of digits after the decimal point, such as 0.5 or 3.14.

Front

What does it mean for a decimal to repeat?

Back

A decimal is said to repeat if it has a sequence of digits that continues infinitely, such as 0.333... or 3.14285714286.

Front

How can you find the equivalent decimal of a fraction?

Back

To find the equivalent decimal of a fraction, divide the numerator by the denominator using long division or a calculator.

Front

What is the significance of matching dot plots?

Back

Matching dot plots helps in understanding the distribution and frequency of data in different populations, allowing for comparisons and insights.

Front

How do you calculate the probability of an event given multiple options?

Back

To calculate the probability of an event from multiple options, compare the probabilities expressed as fractions or percentages and identify the highest value.

Front

What is a constant rate of increase?

Back

A constant rate of increase means that the quantity increases by the same amount in each step or iteration, forming a linear pattern.

Front

How do you express regularity in repeated reasoning in mathematics?

Back

Expressing regularity in repeated reasoning involves identifying patterns and using them to make predictions or solve problems based on established rules.
