Answer:
(C) Elizabeth wants to estimate the mean height of students at her school. She collects data by selecting a random group of students within her classroom.
Step-by-step explanation:
In option C, the sample is an example of convenience sampling, It is not representative of the population of student being studied.
Convenience sampling is a type of non-probability sampling method in which the sample is taken from the part of the population easy to reach.
The sample are not chosen at random thereby undermining the ability to generalize the results from the sample to the entire population under study.

The slope is and the y-intercept is
.
Step-by-step explanation:
We are given an equation in slope-intercept form (y = mx + b).
In this equation, we can define the following variables:
- m = slope
- b = y-intercept
The slope in an equation and of a line is the rise over run of a line. The numerator of the fraction will be how many y-coordinates the line will ascend or descend (depending on the sign). The denominator will signify how many x-coordinates the line will move to the left or the right.
The y-intercept is the coordinate at which the line crosses the y-axis. The value of x is 0 and the coordinate can be positive or negative.
Therefore, by looking at our equation, we can see that is the slope, and 4 is the y-intercept.
