99.7 percentage of the data lies between 140 and 212 pounds when the distribution of the standard deviation is normal.

<h3>What is standard deviation?</h3>

Any given quantity, which is used to express that how many observations  differ from others in the total observations of a data, is referred to as standard deviation. It is represented by σ.

To calculate the percentage of data lying between the given values, we will use the formula of empirical method and the given information to compute as under,

\rm P(mu-3\ x\ \sigma < X < \mu + 3\ x\ \sigma)

Solving further,

\rm P(176-3\ x\ \12 < X < \176+ 3\ x\  12) = 0.997

Hence, the significance upon the standard deviation of data weighted by Naomi is as aforementioned.

2019: 51,000/397,500 * $1,488,000 = $190,913

a2) Depreciation of Mining Facilities:

2018: 41,000/310,000 *$102,300 = $13,530

2019: 51,000/397,500 * $102,300 = $13,125

a3) Depreciation of Mining Equipment

2018: 41,000/310,000 *$46,500 = $6,150

2018: 51,000/397,500 * $46,500 = $5,966

b) Book Values December 31, 2019:

1) Mineral Mine:

Cost = $1,598,000

Accumulated Depletion $387,713 (2018 & 2019)

Book Value = $1,210,287

b2) Structures:

Cost = $102,300

Accumulated Depreciation $26,655 (2018 & 2019)

Book Value = $75,645

True or false: being an actor is required for a director's complete training.
gayaneshka [121]
False. 

In theatre, a director's role and training is independent and separate from that of an actor. The two roles are distinct and do not require participation as the other in order to complete each. A director's training will be complete through activity other than working or being an actor in a production.
