Answer:
160.65 lb
Step-by-step explanation:
4*18.9 = 75.6 lb
8.5*18.9 = 160.65 lb
Look at points (0, -1) and (1, 5).
m = (y2 - y1)/(x2 - x1) = (5 - (-1))/(1 - 0) = 6/1 = 6
Slope = 6
Answer: 6
3520
33-11=22
40 times 22=880
880 times 4=3520
The sample standard deviation is 15.3.
Given data items,
84, 85, 83, 63, 61, 100, 98,
Number of data items, N = 7,
Let x represents the data item,
Mean of the data points,
Hence, sample standard deviation would be,
