<h2>The standard parametric equation for the line is

.</h2>
Step-by-step explanation:
The standard parametric equation for a line generally represented as
; where (a, b, c) is the point that the line passes through and (l, m, n) is the direction vector of the line.
It is given that the line passes through the point (2, -2, 10).
Hence, here (a, b, c) ≡ (2, -2, 10).
Similarly, the direction vector of the line is given by (l, m, n) ≡ (9, 7, 10).
Putting all the values in the equation of the line, the equation becomes

Answer:
The amount of money separating the lowest 80% of the amount invested from the highest 20% in a sampling distribution of 10 of the family's real estate holdings is $238,281.57.
Step-by-step explanation:
Let the random variable <em>X</em> represent the amount of money that the family has invested in different real estate properties.
The random variable <em>X</em> follows a Normal distribution with parameters <em>μ</em> = $225,000 and <em>σ</em> = $50,000.
It is provided that the family has invested in <em>n</em> = 10 different real estate properties.
Then the mean and standard deviation of amount of money that the family has invested in these 10 different real estate properties is:

Now the lowest 80% of the amount invested can be represented as follows:

The value of <em>z</em> is 0.84.
*Use a <em>z</em>-table.
Compute the value of the mean amount invested as follows:


Thus, the amount of money separating the lowest 80% of the amount invested from the highest 20% in a sampling distribution of 10 of the family's real estate holdings is $238,281.57.
