1. Based on the information given, what is the Worthington Family's net worth? Will they qualify for the loan?
1
Net worth:
Will they qualify for the loan? (yes or no)
Question Completion:
The Worthington family has liquid assets of $10,000, use assets of $150,000 and investment assets of $34,000. They also have liabilities totaling $108,000. They need a loan from the bank and to qualify for the loan, they must have a net worth of $100,000. They will incur additional $7,000 in liabilities.
Answer:
1. The Worthington Family's net worth is:
= $79,000.
2. No. They will not qualify for the loan, as their net worth fell short of the requirement by $21,000.
Step-by-step explanation:
a) Data and Calculations:
Worthington Family's net worth:
Liquid assets = $10,000
Use assets = 150,000
Investment assets = 34,000
Total assets = $194,000
Liabilities = 115,000
Net worth = $79,000
Required net worth = $100,000
Shortfall in net worth = $21,000
b) The Worthington Family's net worth is the difference between their assets (the things that they own) and their liabilities (the things that they owe others). It is an important financial metric for calibrating the family's financial health. Computing it provides a useful snapshot of the family's current financial position. Financial institutions and other potential creditors use it to gauge if they might extend some credit facilities to the Worthington family.

Complete question :
According to the National Association of Realtors, it took an average of three weeks to sell a home in 2017. Suppose data for the sale of 39 randomly selected homes sold in Greene County, Ohio, in 2017 showed a sample mean of 3.6 weeks with a sample standard deviation of 2 weeks. Conduct a hypothesis test to determine whether the number of weeks until a house sold in Greene County differed from the national average in 2017. Useα = 0.05for the level of significance, and state your conclusion
Answer:
H0 : μ = 3
H1 : μ ≠ 3
Test statistic = 1.897
Pvalue = 0.0653
fail to reject the Null ; Hence, we conclude that their is no significant to accept the claim that number I weeks taken to sell a house differs.
Step-by-step explanation:
Given :
Sample size, n = 40
Sample mean, x = 3.6
Population mean, μ = 3
Standard deviation, s = 2
The hypothesis :
H0 : μ = 3
H1 : μ ≠ 3
The test statistic :
(xbar - μ) ÷ (s/√n)
(3.6 - 3) / (2/√40)
0.6 / 0.3162277
Test statistic = 1.897
Using T test, we can obtain the Pvalue from the Test statistic value obtained :
df = n - 1; 40 - 1 = 39
Pvalue(1.897, 39) = 0.0653
Decison region :
If Pvalue ≤ α ; Reject the null, if otherwise fail to reject the Null.
α = 0.05
Pvalue > α ; We fail to reject the Null ; Hence, we conclude that their is no significant to accept the claim that number I weeks taken to sell a house differs.

A) 105°
Step-by-step explanation:
The two marked angles are alternate interior angles, so are congruent.
8x +17 = 9x +6
11 = x
8x +17 = 8(11) +17 = 88 +17 = 105 . . . . degrees
The bolded angle is 105°.
Answer:
105 degrees
Step-by-step explanation:
Here ,
8x+17=9x+6(being alternate angles )
17-6=9x-8x

20 POINTS!!!!!!!!!! what are two numbers that multiply to equal -13 but add to equal +7
Answer:
x = -1.525
y = 8.525
Step-by-step explanation:
xy = -13
x + y = 7
we can let 'y' equal 7-x and use substitution
x(7-x) = -13
7x - x² + 13 = 0
divide through by negative one to get a positive x²
x² - 7x - 13 = 0
use the quadratic formula to get:
x = -1.525
y = 8.525

The simplified expression for the area of rectangle ABCD is
Answer:
[tex]\text{Area}=\frac{15(x+1)}{2(x-2)}[/tex]
Step-by-step explanation:
Length of the rectangle given in the picture = [tex]\frac{5x+5}{x+3}[/tex]
Width of the rectangle = [tex]\frac{3x+9}{2x-4}[/tex]
Area of the rectangle = Length × Width
= [tex]\frac{5x+5}{x+3}\times \frac{3x+9}{2x-4}[/tex]
= [tex]\frac{5(x+1)}{x+3}\times \frac{3(x+3)}{2(x-2)}[/tex]
= [tex]\frac{15(x+1)(x+3)}{2(x+3)(x-2)}[/tex]
= [tex]\frac{15(x+1)}{2(x-2)}[/tex]
Therefore, area of the given rectangle is [tex]\frac{15(x+1)}{2(x-2)}[/tex].

Step-by-step explanation:
A lawn service owner is testing new weed killers. He discovered that a particular weed killer was effective 89% of time. Suppose that this estimate was based on a random sample of 60 applications. Find the lower confidence limit (LCL) for a 90% confidence interval for p, the true proportion of weeds killed by this particular brand. Round your answer to two decimal places.
Answer:
The LCL for a 90% confidence interval for p is 0.82.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
A lawn service owner is testing new weed killers. He discovered that a particular weed killer was effective 89% of time. Suppose that this estimate was based on a random sample of 60 applications.
This means that [tex]\pi = 0.89, n = 60[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.89 - 1.645\sqrt{\frac{0.89*0.11}{60}} = 0.8236[/tex]
Rounding to two decimal places, the LCL for a 90% confidence interval for p is 0.82.
Q: using the Substitution Method, and the value ory in
Using the Substitution Method, find the value of y in
the below system of equations?
-2y = 44 – 4
7x = -4y + 10
Answer:
Step-by-step explanation:
To properly apply the substitution method, it will be better for us to rearrange the system of equations to have similar variables on the same side
[tex]44 - 4 = -2y ----equation 1[/tex]
[tex]10 = 7x + 4y --- equation 2[/tex]
We can simply evaluate equation 1 to have
[tex]40 = -2y\\y = 40/-2 = -20\\[/tex]
y = -20
From the first equation alone, we can evaluate the value of y as -20. This is because only one unknown is present in equation one, hence a single equation is sufficient enough to evaluate it. If to unknowns were present, the two equations would have been utilized to evaluate the solution.

x and y are two integers and x ≠ 0. Which of the following is not a rational number? a) z b) y c)x/y d) y/x
Answer: Choice A) z
==========================================================
Explanation:
x and y are two integers, with x being nonzero
This means x/y is rational as long as y is nonzero as well. If y = 0, then we have a division by zero error. Try something like 1/0 on your calculator and you'll find it doesn't work.
Similarly, y/x is rational as well. Any rational number is simply dividing two integers as a fraction like this. Other examples include stuff like 1/2, 4/5, 8/17, and so on.
Since y is an integer, this means we can write it like this: y = y/1. This shows any integer is also rational, but not the other way around. A fraction like 2/3 is rational but not an integer.
All of what was discussed above indicates that choices B, C and D can be ruled out. The only thing left is choice A. The variable z isn't defined, so it's not clear what it is exactly. But it's likely the answer as it's the only thing left after the eliminations.

13) A school counselor asked a random sample of seventh- and eighth-
grade students how long it takes them to get ready for school each
morning. The dot plot and the box plot below summarize the results for
the two random samples. Which statement correctly describes the two
data sets below? *
Answer:
A. The range of both data sets is 40
Step-by-step explanation:
Range = the maximum value - the minimum value
✔️For the Seventh-Grade Students' data set,
Maximum value = 45
Minimum Value = 5
Range = 45 - 5 = 40
✔️✔️For the Eight-Grade Students' data set,
Maximum value = 45 (the value at the whisker to your far right)
Minimum Value = 5 (value indivl ated by the whisker on your far left)
Range = 45 - 5 = 40
Therefore, the two data sets can be described as having the same range of 40.

find the length of the third side.
Thank you!
Answer:
We use Pythagoras' theorem:
[tex] \bf {AC}^{2} = {AB}^{2} + {BC}^{2} \\ \\ \bf {AC}^{2} = ( \frac{12}{13})^{2} + ( \frac{5}{13} )^{2} \\ \\ \bf {AC}^{2} = \frac{ {12}^{2} }{ {13}^{2} } + \frac{ {5}^{2} }{ {13}^{2} } \\ \\ \bf {AC}^{2} = \frac{144}{169} + \frac{25}{169} \\ \\ \bf {AC}^{2} = \frac{169}{169} \\ \\ \bf {AC}^{2} = 1 \\ \\ \bf AC = \sqrt{1} \Rightarrow \red{ \boxed{ \bf AC = 1} } [/tex]
Answer:
AC = 1
Step-by-step explanation:
This is Pythagoras' theorem, which states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.
⇒ Th.P ⇒ AC² = AB² + BC²
<=> AC² = (12/13)² + (5/13)²
<=> AC² = 144+25/169
<=> AC² = 169/169
<=> AC² = 1
⇒ AC = √1 = 1.
Can someone please please answer this
Answer:
10°
Step-by-step explanation:
You can see the three angles shown form a straight line, meaning they add up to 180°. We can et up the equation:
m<AOC + m<COD + m<DOB = 180°
And we can substitute the values we have:
5a + 18 + 24 - a + 8a - 30 = 180
Next, we can combine all like terms:
12a + 12 = 180
12a = 168
a = 14
Now, to find each angle, we can substitute the value of a:
m<AOC = 5a + 18 = 5(14) + 18 = 88°
m<COD = 24 - a = 24 - 14 = 10°
m<DOB = 8a - 30 = 8(14) - 30 = 82°
The smallest angle is <COD with a measure of 10°.
