Explanation Given: The following table is provided, which is used by a professor for assigning letter grades in a course. Grade Total points A Greater than μ + 3 2 σ B μ + 1 2 σ to μ + 3 2 σ C μ − 1 2 σ to μ + 1 2 σ D μ − 3 2 σ to μ − 1 2 σ F B e l o w μ − 3 2 σ Explanation: Here, x = μ + 1 2 σ and x = μ − 1 2 σ . Where, μ = mean mark σ = Standard deviation The z − s c o r e for the two limits is provided by, The z − s c o r e for x = μ + 1 2 σ , z = x − μ σ = μ + 1 2 σ − μ σ = 1 2 = 0

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
