Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 stu
coldgirl [10]
The correct answer would be option D.
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school

The population represents all of the students in the school. Apart from his science class there can be students in arts class, music class, literature class and so on. He used convenience sampling by just surveying the students of his science class. The students in science class are those who are interested in science and related topics so these students will be more inclined towards watching a science program. Thus the survey of Johnny does not yield valid result and his inference is not valid.

Thus, option D is the correct answer.

Find the slope and the y-intercept of the following graph
spin [16.1K]

Answer:

The slope of the graph is 5, and the y-intercept is (0, -3).

Step-by-step explanation:

Let's start by finding the y-intercept.

The y-intercept is the point where the line intercepts the y-axis.

Looking at the graph, we can determine that the y-intercept is (0, -3).

The slope of a graph can be found using two points on the line.

Let's use (0, -3) and (1, 2):

Slope=\frac{Rise}{Run}=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-3)}{1-0}=\frac{5}{1}=5

Therefore the slope of the graph is 5, and the y-intercept is (0, -3).
