Study Notes
Quadratic Equations
- The equation x² + 5x = -3 has solutions x = -5 ± √13.
- The equation 25x² = 36 has solutions x = ± 6/5.
Data Representation
- A dot plot represents a set of golf scores.
- A histogram represents a set of data, and the correct data set can be identified by matching the shape and range of the histogram.
Histograms and Box Plots
- A histogram is a graphical representation of a data set, showing the frequency of each range of values.
- A box plot represents a data set, showing the minimum, maximum, median, and quartiles.
- The correct box plot for a data set can be identified by matching the shape and range of the plot.
Data Analysis
- Mr. Jeffer's class studies math per week, with hours studied ranging from 2 to 7.
- The data set can be represented by a box plot, with the correct plot showing the spread and distribution of the data.
