Study Notes

Perimeter of a Rectangle

To calculate the perimeter of a rectangle, add the lengths of all four sides together.
The formula for the perimeter of a rectangle is P = 2l + 2w, where l is the length and w is the width.

Geometric Transformations

The shape's original angles must be preserved when transforming a geometric shape.

Summarizing Large Data Sets

The best method for summarizing large data sets depends on the data's nature but histograms are often used because they visually represent frequency distributions within a data set.

Volume of a Cylinder

In 3D geometry, the radius of a cylinder's base directly influences its volume because the volume is calculated using the formula V = πr²h, where r is the radius and h is the height.

Probability

Probability is a measure of the likelihood of an event occurring.
The sum of probabilities for all possible outcomes of an event must equal 1.
