Wynona buys some new boots that are priced $85. 79. She gets successive discounts of 10% followed by 5% off on the boots. The purchase price of Wynona’s boots is _____ of the original price. A. 84% b. 84. 5% c. 85% d. 85. 5%.
Answers
The purchase price of Wynona’s boots is 85.5% of the original price.
It is given that
The marked price of boots = $85.79
What is the percentage?The percentage is a relative value indicating the hundredth parts of any quantity.
Price after a discount of 10% = \(85.79 - 85.79*10/100 = 77.211\)
Price after another discount of 5% = \(77.211-77.211*5/100 = 73.35\)
\(\frac{PurchasePrice}{OriginalPrice}*100 =\frac{73.35}{85.79}*100 = 85.5\)
Therefore, The purchase price of Wynona’s boots is 85.5% of the original price.

The economy is in a recession. Real GDP is well below potential GDP. If the government wants to increase real GDP so that it is closer to potential GDP, it could ____. (Select all that apply.) Group of answer choices -increase government spending -decrease government spending -decrease taxes -increase taxes
Answers
To increase real GDP and bring it closer to potential GDP during a recession, the government could increase government spending and/or decrease taxes.
During a recession, when real GDP is below potential GDP, the government can use fiscal policy tools to stimulate economic growth and close the GDP gap. The two options that can be effective in this situation are increasing government spending and decreasing taxes.
Increase government spending: By increasing spending on infrastructure projects, education, healthcare, or other sectors, the government can create demand in the economy, which leads to increased production and employment, ultimately raising real GDP.
Decrease taxes: Reducing taxes can provide individuals and businesses with more disposable income, encouraging consumption and investment. This increased spending and investment can boost aggregate demand, leading to higher production levels and closing the GDP gap.
Decreasing government spending and increasing taxes, on the other hand, would have contractionary effects, potentially exacerbating the recessionary conditions by reducing overall demand in the economy. Therefore, these options are not suitable for increasing real GDP during a recession.

Answer:
\(\frac{3 - 7}{-4 - (-7)} = \frac{-5 - 3}{2 - (-4)}\)
Step-by-step explanation:
See attachment for complete question
From the attachment, we have that:
\(P = (-7,7)\)
\(Q = (-7,3)\)
\(R = (-4,3)\)
\(S = (-4,5)\)
\(T = (2,-5)\)
First, we need to calculate the slope (m) of PQR
Here, we consider P and R
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
Where
\(P(x_1,y_1) = (-7,7)\)
\(R(x_2,y_2) = (-4,3)\)
\(m = \frac{y_2 - y_1}{x_2 - x_1}\) becomes
\(m = \frac{3 - 7}{-4 - (-7)}\) --------- (1)
Next, we calculate the slope (m) of RST
Here, we consider R and T
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
Where
\(R(x_1,y_1) = (-4,3)\)
\(T (x_2,y_2)= (2,-5)\)
\(m = \frac{y_2 - y_1}{x_2 - x_1}\) becomes
\(m = \frac{-5 - 3}{2 - (-4)}\) ---------- (2)
Next, we equate (1) and (2)
\(\frac{3 - 7}{-4 - (-7)} = \frac{-5 - 3}{2 - (-4)}\)

Let A (3,17,29,45) and B (4,6,22,60). A relation R from A to B is defined by aRb if and only if atb is a prime. a. Find the relation R b. Is R a function from A to B?
Answers
a) The relation R from set A={13, 17, 29, 45} to set B={4, 6, 22, 60} is {(13,4), (13,6), (13,60), (17,6), (17,22), (29,22)}.
b) R is a function from A to B.
a) We need to find all pairs of elements (a, b) such that aRb, where a is an element of set A and b is an element of set B. According to the definition of R, aRb if and only if a+b is a prime number.
Let's start with the first element of set A, which is 13. We need to find all elements of set B that satisfy the condition a+b is a prime number, where a=13. We have:
13+4=17 (prime)
13+6=19 (prime)
13+22=35 (not prime)
13+60=73 (prime)
So, for a=13, the elements of set B that satisfy the condition are 4, 6, and 60. We can repeat this process for the other elements of set A to find all pairs of elements (a, b) such that aRb. The results are:
For a=17, the elements of set B that satisfy the condition are 6 and 22.
For a=29, the element of set B that satisfies the condition is 22.
For a=45, there are no elements of set B that satisfy the condition.
Therefore, the relation R from set A to set B is {(13,4), (13,6), (13,60), (17,6), (17,22), (29,22)}.
b) To determine if R is a function from A to B, we need to check if each element of set A is related to at most one element of set B. In other words, we need to check if there are any duplicate elements in the first coordinate of the ordered pairs in R.
In our case, there are no duplicates in the first coordinate, so each element of set A is related to at most one element of set B. Therefore, R is a function from A to B.

What is the 1.5 IQR rule for outliers?
Add 1.5 to the interquartile range (IQR) (a constant used to discern outliers). The third quartile is increased by 1.5 times (IQR). Any figure above this is thought to be an outlier.
The starting and the end of the box in box plot are first and third quartile respectively.
From the given box plot it is clear that, Q₁ = 34 and Q₃ = 38
IQR = Q₃ - Q₁
IQR = 38 - 34
IQR = 4
According to 1.5x IQR rule for outliers, all the data values lies outside the interval [ Q₁ - 1.5 × IQR , Q₃ + 1.5 × IQR ] are outliers..
Q₃ + 1.5 × IQR = 38 + 1.5(4)
Q₃ + 1.5 × IQR = 38 + 6
Q₃ + 1.5 × IQR = 44
We know that, 43<44.
Since, 43 is not greater than Q₃ + 1.5 × IQR therefore, 43 is not an outlier and there is no evidence to support the claim.

No, because it is plausible that she would make 3 or fewer shots by chance alone.
What is convincing evidence?
The proof is sufficient evidence or a sufficient argument for the truth of a proposition. The concept applies in a variety of disciplines, with both the nature of the evidence or justification and the criteria for sufficiency being area-dependent.
if our test statistic is: positive and greater than the critical value, then we have sufficient evidence to reject the null hypothesis and accept the alternative hypothesis. positive and lower than or equal to the critical value, we must accept the null hypothesis.

Answers
The largest group of students that the study results represent is "all UCLA graduate student apartments in the three sampled buildings".
The number of graduate student apartments in the three sampled buildings can be represented mathematically as:
N = 25 * 3
Where N is the number of apartments sampled and 25 is the number of apartments randomly selected in each of the three buildings.
This expression represents the total number of apartments in the largest group that the study results represent, which is "all UCLA graduate student apartments in the three sampled buildings."
This is because the survey only included data from 25 apartments in each of the three randomly selected buildings. The results of the study cannot be generalized to represent all UCLA graduate student apartments or even all apartments in the group of seven buildings as the sample size is limited to only three buildings. The results only provide information about the energy efficiency of the apartments in the three sampled buildings.

The identity that shows that GDP is both total income and total expenditure is represented by a. GDP = Y. C. GDP = GNP - NX. b. Y = DI+T+NX. d. Y=C+I+G+NX.
Answers
The correct answer is d. Y = C + I + G + NX. This equation represents the identity that shows GDP (Gross Domestic Product) as both total income and total expenditure.
Let's break down the components of the equation:
Y represents GDP, which stands for the total value of all final goods and services produced within a country's borders during a specific time period.C represents consumption expenditure, which includes the spending by households on goods and services.I represents investment expenditure, which includes spending on capital goods, such as machinery and equipment, as well as changes in inventory levels.G represents government expenditure, which includes spending by the government on goods and services.NX represents net exports, which is the difference between a country's exports (X) and imports (M). It indicates the contribution of international trade to the economy.By summing up the components of consumption expenditure (C), investment expenditure (I), government expenditure (G), and net exports (NX), we arrive at GDP (Y). This equation demonstrates that GDP is both the total income earned by individuals and businesses in producing goods and services (represented by C + I + G + NX) and the total expenditure on those goods and services.

To find the composition of two functions, (f g)(x), we first evaluate g(x) and then substitute the result into f(x).
So, let's first evaluate g(x):
g(x) = 8x² - 5x + 7
Next, substitute g(x) into f(x):
(f g)(x) = f(g(x)) = f(8x² - 5x + 7) = -2(8x² - 5x + 7) = -16x² + 10x - 14
Therefore, (f g)(x) = -16x² + 10x - 14.

The millage rate is the amount of property tax per $1000 of the taxable value of a home. For a certain county the millage rate is 29 mil. A city within the county also imposes a flat fee of $101 per home. a. Write a function representing the total amount of property tax T(x) for a home with a taxable value of x thousand dollars. b. Write an equation for T-1(x). c. What does the inverse function represent in the context of this problem
Answers
Answer:
(a) \(T(x) = 101 + 0.029 x\)
(b) \(T^{-1}(x) = \frac{1000(x - 101)}{29}\)
(c) See explanation
Step-by-step explanation:
\(T(x) = 172 + \frac{29}{1000}x\)
Given
\(Flat = 101\)
\(Rate = 29\ per\ 1000\)
Solving (a): The function for total amount
This is calculated as:
\(T(x) = Flat + Rate * x\)
Where:
\(x \to\) taxable value
So, we have:
\(T(x) = 101 + \frac{29}{1000} * x\)
\(T(x) = 101 + 0.029 * x\)
\(T(x) = 101 + 0.029 x\)
Solving (b): The inverse function
\(T(x) = 101 + 0.029 x\)
Rewrite as:
\(y = 101 + 0.029x\)
Swap the variables
\(x = 101 + 0.029y\)
Make y the subject
\(0.029y = x - 101\)
Divide by 0.029
\(y = \frac{x - 101}{0.029}\)
Multiply by 1000/1000
\(y = \frac{1000(x - 101)}{29}\)
Replace y with the inverse function
\(T^{-1}(x) = \frac{1000(x - 101)}{29}\)
Solving (c): Interpret (b)
The inverse function, in this case; is the taxable value calculated from the amount of property tax
