Write the equation of the line fully simplified slope-intercept form.
zmey [24]

Answer:5y=x-35

Step-by-step explanation:

The given line passes through the points (0,-7),(10,-5).

Let the slope of the line be m.

If a line passes through (x_{1},y_{1}) and (x_{2},y_{2}),then

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

So,m=\frac{-7-(-5)}{0-10}=\frac{1}{5}

Y-intercept of a line is defined as the y-coordinate of the point where the line touches y axis.

Let the y intercept be b

From the graph,b=-7

The equation of the line with slope m and y-intercept b is y=mx+b

So,y=\frac{1}{5}x-7

5y=x-35

A financial advisor is analyzing a family's estate plan. The amount of money that the family has invested in different real esta
Pachacha [2.7K]

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:

\mu_{\bar x}=\mu=\$225,000\\\\\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}=\frac{50000}{\sqrt{10}}=15811.39

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

P(\bar X

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:

\bar x=\mu_{\bar x}+z\cdot \sigma_{\bar x}

   =225000+(0.84\times 15811.39)\\\\=225000+13281.5676\\\\=238281.5676\\\\\approx 238281.57

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.
