Do all horizontal lines have the same slope
2 answers:
Answer: Yes
Step-by-step explanation: For any horizontal or flat line, the slope will always be the same which simplify to 0.
Let's look at an example which I have provided in the first image attached. I have labeled two points on the line and they are point A and point B.
To get from point A to point B along this line, our rise is 0 units and our run is 3 units so our slope or rise over run is 0/3. However, 0/3 can be simplified to 0. So for this line, our slope or <em>m</em> equals 0.

Answer:
The correct option is C) 21.1 and 0.68
Step-by-step explanation:
Consider the provided information.
The mean composite score was 21.1 with a standard deviation of 4.8. The ACT composite score ranges from 1 to 36, with higher scores indicating greater achievement in high school.
Therefore μ = 21.1 and σ = 4.8
It is given that the sample of 50 students;
Thus, sample size ( n ) = 50
According to the central limit theorem,
Therefore
Hence, the correct option is C) 21.1 and 0.68
