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.

Answer:

0.76

Explanation:

So, in this particular question we are given that that there are two assets which are the; [1]. stock fund and [2]. a long-term government and corporate bond fund.

From the question/problem, we have that the Expected ret and the std. dev. for the Stock fund is 18% and 25% respectively. Also, the Expected ret and std. dev. for  Bond fund 11% and 18% respectively.

Thus, the investment proportion in the minimum variance portfolio of the bond fund = 1 - [ ( 18%)² - 0.4 × 25% × 18%) ÷ ( 25%)² + (18%)² - 2 × 0.4 × 25% × 18%. = 1 - [0.0144 ÷ 0.0609 ] = 1 - 0.24 = 0.76.

Answer: B. $65,000

Explanation:

The options to the question are:

A. $15,000

B. $65,000

C. $150,000

D. $200,000

It should be noted that the corporate liquidations of property are typically treated as either an exchange or a sale and the profit or the loss made will be recognized by the corporation usually based on the liquidating sale of the assets of the corporation.

In certain cases whereby the distributee that is, the individual who is entitled to partake in the share of an estate distribution is a corporation that is in charge of the distributing corporation, this may lead to the distribution not to be taxable.

Due to this, Alvo has a basis of $65,000. The reason is that the land was not sold and therefore Alvo did not get $200,000.

Dora earns 50,000 a year at her johs. when she was given a raise of 5,000 her spending increased from 50,000 to 54,000 calvulate
weqwewe [10]
Given:
ΔY = $5,000, the change in income
ΔS = 50,000 - 54,000 = - 4,000, the change in savings.

By definition,
MPS (Marginal Propensity to Spend) is
MPS = ΔS/ΔY = -4000/5000 = -0.8

The relation between MPS and MPC (Marginal Propensity to Consume) is
MPS + MPC = 1.
Therefore
MPC - 0.8 = 1
MPC = 1.8

Answer:
MPS = 0.8
MPC = 1.8
