Mariana [72]

Answer:

1. $ \mu = \$306,500 $

2. \sigma = \$24,500

3. n = 150

4. $ \mu_{x}= \mu = \$306,500 $

5. \sigma_x = \$ 2,000 \\\\

Step-by-step explanation:

The average mortgage owed by Americans is $306,500, with a standard deviation of $24,500.

From the above information, we know that,  

The population mean is

$ \mu = \$306,500 $

The population standard deviation is

\sigma = \$24,500

Suppose a random sample of 150 Americans is selected

n = 150

Since the sample size is quite large then according to the central limit theorem, the sample mean is approximately normally distributed.

The sample mean would be the same as the population mean  that is

$ \mu_{x}= \mu = \$306,500 $

The sample standard deviation is given by

\sigma_x = \frac{\sigma}{\sqrt{n} }

Where \sigma is the population standard deviation and n is the sample size.

\sigma_x = \frac{24,500}{\sqrt{150} }  \\\\\sigma_x = \$ 2,000 \\\\

Therefore, the required parameters are:

1. $ \mu = \$306,500 $

2. \sigma = \$24,500

3. n = 150

4. $ \mu_{x}= \mu = \$306,500 $

5. \sigma_x = \$ 2,000 \\\\

Pablo bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $250 more than the desktop. He pa
olga55 [171]
A = price of the desktop

b = price of the laptop

now, we know the laptop was more expensive than the desktop by 250 bucks, thus b = a + 250.

for "a", he paid 8.5% in interest, for "b", he paid 5% in interest.

how much is 8.5% of a?  well (8.5/100) * a, or 0.085a.

how much is 5% of b?  well, (5/100) * b, or 0.05b.

now, we know the total charges for financing were $296, that means the interest paid in total was 296, thus whatever "a" or "b" are, we know that  0.085a + 0.05b = 296.

\bf \begin{cases}
\boxed{b}=a+250\\
0.085a+0.05b=296\\
----------\\
0.085a+0.05\left( \boxed{a+250} \right)=296
\end{cases}
\\\\\\
0.085a+0.05a+12.5=296\implies 0.135a=283.5
\\\\\\
a=\cfrac{283.5}{0.135}\implies a=2100

how much did the laptop cost?  well, b = a + 250.

Answer:

The new points to the triangle will be:

A(-6, 6)\\B(-6, 3)\\C(-8, 3)

Step-by-step explanation:

Because the reflection point is at x = -1, all x values will subtract their distances from x = -1 to get their new values. The y values remain the same.

The starting values are:

A(4,6)\\B(4,3)\\C(6,3)

Point A is 5 units away from x = -1, so we'll subtract 5 from -1 to get the new x value: -1 - 5 = -6, so A(-6, 6).

Point B is also 5 unit away from x = -1, so we'll subtract 5 from -1 to get the new x value: -1 - 5 = -6, so B(-6, 3).

Point C is 7 units away from x = -1, so we'll subtract 7 from -1 to get the new x value: -1 - 7 = -8, so C(-8, 3).

A seagull has a vertical position a, and a shark has a vertical position b. Draw and label a point on the vertical axis to show
notsponge [240]

Answer:

Image attached

Step-by-step explanation:

The question asks to represent the position of two animals in a the cartesian coordinates plane. This is two perpendicular axis, the y-axis is the vertical one and the x-axis is the horizontal one. The animals are represented by dots, called a for the seagull and b for the shark.

Since the y-axis is the vertical axis and they ask to draw the points with a verical difference between them, we will draw the points in it.

Say the x-axis represents the sea surfice. The seagull would be over the sea, and the shark under the sea surfice (under x-axis).

This is the resulting drawing
