... (and it is believed that the ethnic groups are relevant) In a simple random sample, some ethnic groups could be overrepresented or under-represented. In order to reduce the error, random sampling can be done with 70% of people from group A, 20% from group B, 10% from group C. This method is called s ...

... I can identify a rational number as a point on the number line. I can reason that when only the x value in a set of ordered pairs are opposites, it creates a reflection over the y axis, e.g. (x, y) and (-x, y). I can identify the location of zero on a number line in relation to positive and ne ...
