Answer:
Each pencil costs 20 cents
Step-by-step explanation:
2.40 - 1 = 1.40
1.40/7 = 0.2
18,38,38,40,44,44,44,46,48....
the mean with the outlier (18) included is : 360/9 = 40
38,38,40,44,44,44,46,48
the mean with the outlier (18) excluded is : (360 - 18) / 9 = 342/9 = 38
so when the outlier is removed, the mean is 2 points less
Answer:
0
Step-by-step explanation:
To calculate the slope or gradient we use this formula:
Slope = y2-y1/x2-x1
(-3,2) = (x1, y1)
(4,2) = (x2, y2)
Slope = 2-2/4-(-3) = 0
