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.

ANTONII [103]

Answer:

It is $18,290.24

Explanation:

Profit after Tax (65%) = addition to retained earnings+dividend paid

                                   = $411 +  $285

                                    = $ 696

Profit before Tax = [100/65] * $ 696

                            = $1070.76

Tax (35%)             = 35% * $1070.76

                            = $374.77

Gross Profit = Profit before tax + Total expenses

                    = $1070.76 + [  $4,370+ $103+ $812]

                    = $6355.76

Cost of Sales= $24,646 -$6355.76

                     = $18,290.24 .

Note

-Dividend is paid is paid from profit after tax

cricket20 [7]

Both power distance and femininity are negatively related to the Environmental Sustainability Index. False

<h3>What is Environmental Sustainability?</h3>

Environmental sustainability is described as appropriate contact with the environment that promotes long-term environmental quality while preventing resource depletion or degradation. Environmental sustainability is a method that makes it possible to meet the requirements of the current generation without endangering the ability of future generations to do the same.

The power of the natural environment to renew itself and maintain its viability is really amazing when viewed in that light. For instance, when a tree falls, its decomposition enriches the earth with nutrients. These nutrients provide the right environment so that subsequent saplings can thrive.

Nature has a great capacity to take care of itself when left alone.
