It's called a linear equation because the linear equation formula is y= mx+b, so they just changed the m to an a

the area of the trapezoid is 64
Answer:
Z-score = 3.73
Yes, the maximum value (21) in this data set is a high outlier.
Step-by-step explanation:
I'll solve for what you haven't done yet, z-score and whether or not the maximum is an outlier.
Z-score tells us how many standard deviations a value is above or below the mean. The formula for z-score is .
Substituting , we get .
To determine if a value is an outlier, we use IQR, or Interquartile Range. If a value is lower than or higher than , then we say it is an outlier.
With the value of 21, clearly we are only worried about it being a high outlier. Q1 is the median of the first half of the data and Q3 is the median of the second half. In this case, Q1 is 2 and Q3 is 6.5. IQR is equal to Q3-Q1, or 4.5 in this case.
Therefore, the higher limit for outliers is . Any values above 13.25 are considered high outliers. Therefore, the maximum value of 21 is a high outlier.
