Study Notes
Fractions to Decimals
- A fraction can be converted to a decimal by dividing the numerator by the denominator.
- For example, the fraction 3/4 can be converted to a decimal by dividing 3 by 4, which equals 0.75.
- A decimal can be converted to a fraction by finding the equivalent ratio.
- For example, the decimal 0.5 can be converted to a fraction by finding the equivalent ratio, which is 1/2.
Value of a Fraction
- The value of a fraction is determined by the numerator and denominator.
- A fraction with a larger numerator and a smaller denominator has a greater value.
- A fraction with a smaller numerator and a larger denominator has a smaller value.
- Equivalent fractions have the same value, but different forms.
Equation of a Line
- The equation of a line can be written in the form y = mx + b, where:
- m is the slope (a measure of how steep the line is)
- b is the y-intercept (the point where the line crosses the y-axis)
- x is the independent variable
- y is the dependent variable
- The slope-intercept form is one of the most common forms of a linear equation.
- The equation of a line can also be written in point-slope form or standard form.
Frequency Table
- A frequency table is a table that displays the frequency of each value or category in a dataset.
- The frequency of each value is the number of times it appears in the dataset.
- A frequency table can be used to summarize and organize data.
- It can also be used to calculate the mode, median, and range of a dataset.
Probability
- Probability is a measure of the likelihood of an event occurring.
- It is a number between 0 and 1, where:
- 0 represents an impossible event
- 1 represents a certain event
- The probability of an event can be calculated using the formula: P(event) = number of favorable outcomes / total number of outcomes
- Probability can be used to make predictions and estimate the likelihood of an event occurring.
Pie Charts
- A pie chart is a circular graph that displays the proportion of each category in a dataset.
- The pie chart is divided into sections, each representing a category.
- The size of each section is proportional to the frequency or percentage of the category.
- Pie charts are used to display categorical data and to compare the proportions of different categories.
- They can also be used to show how different categories contribute to a whole.
Fractions to Decimals
- Converting a fraction to a decimal involves dividing the numerator by the denominator, e.g., 3/4 = 3 ÷ 4 = 0.75.
- Converting a decimal to a fraction involves finding the equivalent ratio, e.g., 0.5 = 1/2.
Value of a Fraction
- A fraction's value is determined by its numerator and denominator.
- A fraction with a larger numerator and smaller denominator has a greater value.
- A fraction with a smaller numerator and larger denominator has a smaller value.
- Equivalent fractions have the same value but different forms.
Equation of a Line
- The equation of a line can be written in the form y = mx + b, where: • m is the slope (steepness of the line) • b is the y-intercept (point where the line crosses the y-axis) • x is the independent variable • y is the dependent variable
- The slope-intercept form is a common form of a linear equation.
- The equation of a line can also be written in point-slope form or standard form.
