When dealing with a pool of data, the field of study is called statistics. This refers to the study of sample data and how they correlate it with the overall trend of the population. By doing this, they use terms that can best represent the sample data. These three are the most common:
1. Mean - this is the arithmetic average of the data
Mean = (<span>8+41+25+9+22+36+24+13+25+28)/10 = 23.1
2. Mode - this is the most frequent data point that can occur. In this case, the mode is 25 because it occurred twice.
3. Median - this is the middle of the sample data arranging it from least to greatest. In this case: 8, 9, 13, 22, 24, 25, 25, 28, 36, 41. The middle number is 25. Thus, the median is 25.</span>
Answer:
Step-by-step explanation:
H(3,2) & J(4, 1)
K(-2,-4) & M(-1 , -5)
![Slope =\dfrac{-5-[-4]}{-1-[-2]}\\\\=\dfrac{-5+4}{-1+2}\\\\= \dfrac{-1}{1}\\\\\\= -1](https://tex.z-dn.net/?f=Slope%20%3D%5Cdfrac%7B-5-%5B-4%5D%7D%7B-1-%5B-2%5D%7D%5C%5C%5C%5C%3D%5Cdfrac%7B-5%2B4%7D%7B-1%2B2%7D%5C%5C%5C%5C%3D%20%5Cdfrac%7B-1%7D%7B1%7D%5C%5C%5C%5C%5C%5C%3D%20-1)
Line HJ and KM have same slopes. So, they are parallel
Answer: Choice B) 
Work Shown:
Note: secant is positive in quadrant Q4, when theta is between 3pi/2 radians and 2pi radians (270 degrees and 360 degrees). So that's why we don't consider the minus form of the plus minus.
