The Steven's family owns a house worth $280,000, of which they still owe $113,545 on the mortgage. They also own two cars, one worth $5,200 and the other worth $15,600. They still owe $9,200 on one of the car loans. They have $2,300 in credit card debt and owe $18,200 for their daughter's wedding. What is their net worth?

A) $157,555
B) $162,155
C) $300,800
D) $143,245

Answers

9514 1404 393

Answer:

A) $157,555

Step-by-step explanation:

The sum of assets is ...

house + 2 cars = $280,000 +5,200 +15,600 = $300,800

The sum of liabilities is ...

mortgage +car loan +credit card +wedding

= $113,545 +9,200 +2,300 +18,200 = $143,245

The family's net worth is the difference between assets and liabilities:

$300,800 -143,245 = $157,555

Calculate the standard deviation of X for the probability distribution. (Round your answer to two decimal places.)
x 0 1 2 3
P(X = x) 0.1 0.5 0.1 0.3

Answers

Answer:

The standard deviation of the probability distribution is 1.02.

Step-by-step explanation:

Standard deviation of the distribution:

Square root of the sum of the difference squared between each value and the mean multiplied by its probability.

Mean:

Each value multiplied by its probability. So

[tex]E(X) = 0*0.1 +1*0.5 + 2*0.1 + 3*0.3 = 1.6[/tex]

Standard deviation:

[tex]\sqrt{V(X)} = \sqrt{0.1*(0-1.6)^2 + 0.5*(1-1.6)^2 + 0.1*(2-1.6)^2 + 0.3*(3-1.6)^2} = 1.02[/tex]

The standard deviation of the probability distribution is 1.02.

What is the unit rate for the ratio 4/7: 8/21?

Answers

Answer:

The unit rate is 1.5

Step-by-step explanation:

Given

[tex]Ratio = 4/7 : 8/21[/tex]

Required

Determine the unit rate

To do this, we need to express the ratio as:

[tex]Ratio = m : 1[/tex]

Where m is the unit rate

[tex]Ratio = 4/7 : 8/21[/tex]

Express as fraction

[tex]Ratio = \frac{4/7 }{ 8/21}[/tex]

Solve

[tex]Ratio = \frac{4}{7} * \frac{21}{8}[/tex]

[tex]Ratio = 1.5[/tex]

Express as ratio

[tex]Ratio = 1.5 : 1[/tex]

Hence, the unit rate is 1.5

A set of data is normally distributed with a mean of 455 and a standard deviation of 25. What percent of the data is in the interval 405–455?
a.
47.5%
c.
68.3%
b.
49.85%
d.
34.15%

Answers

Answer:

a. 47.5%

Step-by-step explanation:

1. Find the z-score for 405: 405-455/25 = -2

2. Find the z-score for 455: 455-455/25 = 0

3. Using technology or a chart, find the percentage that corresponds with the z-scores: -2 = 0.0228 or 2.28%, AND 0 = 0.5000 or 50%

4. Find the difference between the percentages by subtracting them: 50% - 2.28% = 47.72%

5. Most of the time, the answers aren't exact, so since 47.72% is closest to 47.5%, I would say that's the answer.

Here, we have to factorise :

- 12n - 20

Consider the largest number which is the factor of both -12 and -20, that is -4.

→ -4 × 3n = -12n

→ -4 × 5 = -20

Taking (-4) as common,

→ -4( 3n + 5 )

A) 181 in
B) 189 in
C) 196 in
D) 208 in
E) 210 in
None of the above
+3

Answers

Answer:

The right answer is approximately 210.031 cubic inches. (Answer: E)

Step-by-step explanation:

First, we need to convert the diameter ([tex]D[/tex]), in inches, of the round balloon to an entirely decimal mode:

[tex]D = 7\,in + \frac{3}{8}\,in[/tex]

[tex]D = \frac{56 + 3}{8}\,in[/tex]

[tex]D = \frac{59}{8}\,in[/tex]

[tex]D \approx 7.375\,in[/tex]

The volume of the balloon is modelled after the volume function of a sphere ([tex]V[/tex]), in cubic inches:

[tex]V = \frac{\pi}{6}\cdot D^{3}[/tex] (1)

If we know that [tex]D \approx 7.375\,in[/tex], then the volume of the round balloon is:

[tex]V = \frac{\pi}{6}\cdot D^{3}[/tex]

[tex]V = \frac{\pi}{6} \cdot (7.375\,in)^{3}[/tex]

[tex]V \approx 210.031\,in^{3}[/tex]

Hence, the right answer is approximately 210.031 cubic inches.

or 52.63 inches.

Step-by-step explanation:

"So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius."

let's use, πr + 2r

Diameter: 52

Radius: 26 (RAdius is half of the diameter)

πr + 2r (plug in)

pi x 26 + 2(26)

pi x 26 + 52

= 133.681 cm
