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.

Can we say that students read more pages of the book when it is put online?
8. A local 7-Eleven sells a “Memory Pill" that is supposed to help people...um...remember.
You find some Oxnard College students and randomly divide them into two groups of 15
students each. One group takes the actual "Memory Pill" and the other group takes the
placebo. You then show them a list of 20 items and want them to remember as many as
possible.
The experimental group (those taking the pill) remembered an average of 12.3 items from
the list, with a sample standard deviation of 5.4. The control group (with the placeb0)
remembered an average of 10.9 items, with a sample standard deviation of 4.2.
Is this enough evidence to show that the “Memory Pill" improves...well..memory?
