Answer:
The answer is the third one.
Step-by-step explanation:
72 and 99 are values in this set because they are the lower and upper extremes, respectively.
The midrange is the average of the highest value and the lowest value (the extremes). 72 + 99 = 171. 171 / 2 = 85.5
The median is 81, because that is where the line in the middle is at.
Each part of the plot equals 25%. Since the lower two quartiles equal 50%, and so do the upper two quartiles, they're the same. This is the answer.
I hope this helped! :-)
Answer:
y = -1/5x + 2.6
Step-by-step explanation:
Put the equation into slope intercept form:
5x - y = 12
-y = -5x + 12
y = 5x - 12
The slope of a perpendicular line will be the opposite reciprocal.
So, the slope of the new line will be -1/5
Then, plug this slope and the given point into the equation y = mx + b to find b
y = mx + b
3 = -1/5(-2) + b
3 = 0.4 + b
2.6 = b
So, the equation will be y = -1/5x + 2.6
