<h2>Answer:</h2>

The answers are as follows:

Biases samples are those where some members of the population are not included in the survey. These samples produce biases results.

The statements that could lead to biased results are :

1. Giving a standardized test to a class of at-risk students : Only at risk students are biased samples here.

2. Asking players on a school football team how much they study : The school football team will have a very few students as compared to the whole school.

3. Asking Republicans for their opinion about a Democrat-sponsored bill : The republicans here are a part of all the population that contains democrats, liberals and republicans. So sample is biased.

Explain to me in words how you would find the slope of this line and explain answer
Andrews [41]
Answer:
7/3

Explanation:
The slope of the line is equal to the rise/run, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.

We can identify the slope using any two points on the line. Here, we can use the two points that are marked on the picture. The second point is 7 units above the first and 3 units to the right of the first, so the slope of the line is equal to 7/3.

Another way to calculate the slope of the line is the use this formula:

(y2-y1)/(x2-x1)

The first point is at the coordinate (1,-4) and second point is at the coordinate (4,3). When we plug these two coordinates into the equation, we get this:

(y2-y1)/(x2-x1)
->(3-(-4))/(4-1)

When we simply the fraction, we would get 7/3 and that would give us the slope.

I hope this helps!
