The measures of variability for each class are listed:
Class A: Class B:
Range : 30 Range: 30
IQR: 12.5 IQR: 20.5
MAD: 7.2 MAD: 9.2
The interquartile range and the mean absolute deviations for class B are larger number therefore indicating that there is more variability in that data set.
Answer:3 and 1/2 units
Step-by-step explanation:
Answer: 60° angle
Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
Answer:
7/2
Step-by-step explanation:
The slope of the line is given by
m = (y2-y1)/(x2-x1)
= (12-5)/(3-1)
= 7/2
