XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Euclidean Geometry

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

Lines and Angles

In class, we compared healing times for females who received an experimental cold sore medicine. The data for the male control and treatment groups are provided below; they represent the number of days that passed before the sores were completely gone. In your notebook, make a dotplot for each group. Control: 20,13,22,21,16,5,21,11,16,14,15,15,13,16,10,17,16,11,21 Treatment: 11,16,8,16,15,12,11,12,12,9,11,19,16,13,5,15,12,8,11 Part A: Calculate the mean healing time for the control group, rounding your result to the nearest hundredth. In your notebook, mark an "X" on the horizontal axis of your dotplot to show the mean.Mean = daysPart B: Calculate the mean healing time for the treatment group, rounding your result to the nearest hundredth. In your notebook, mark an "X" on the horizontal axis of your dotplot to show the mean.Mean = days
