Explain how to find the deviation of an entry in a data set

1 answer:

3 0

The answer is: Find the mean of the differences with the other numbers in the set. Add the squared differences and then divide the total by the number of items in data in your set; take the square root of this mean of differences to find the standard deviation.

Answer:

76.8

Step-by-step explanation:

density × volume = mass

mass = 62.4 × (pi × (40/2)² × h)

mass = 78,374.4h

WD = m×9.8×h = 9.8mh

WD = 768,069.12h²

At h = 5

WD = 768,069.12×5²

= 19,201,728 ft-lb

= 19.2 million ft-lb

At h = 10

WD = 76,806,9.12 × 10²

WD = 76,806,912 ft-lb

= 76.8 million ft-lb
