Answer:
$204
Step-by-step explanation:
First, you have to find the price without VAT. To calculate it you have to divide the price including VAT by one plus the rate:
Price including VAT= $240
VAT= 14%
240/(1+0.14)= 240/1.14= 210.52
Now, you have to calculate the 15% of 210.52 and subtract that amount from the price:
210.52*0.15=31.57
210.52-31.57=178.95
Then, you have to calculate the 14% VAT by multiplying the price for 1 plus the rate:
178.95*(1+0.14)= 178.95*1.14= 204
According to this, the reduced price of the shoes including VAT is $204.

Factor 24g - 36h. Remember that your answer needs to be factored completely.
Answer:
The completed factor is [tex]=12(2g- 3h)[/tex]Step-by-step explanation:
To factor the expression we need to look for a value that is unique to both terms in the expression.
Given the expression
[tex]24g - 36h[/tex]
The available factors common to both terms are 2,3,4,6,8,12. but since we are expected to factor the expression completely we will use the greatest common factor (gcf) to find the solution
The greatest but common factor is 12, hence we have
[tex]=12(2g- 3h)[/tex]

Select four statements from the invertible matrix theorem and show that all four statements are true or false
This learning module introduced the invertible matrix theorem. This theorem is a collection of 12 equivalent statements. This means that when one statement in the theorem is true, all statements in the theorem are true. Similarly, when one statement in the theorem is false, all statements are false. For your initial post, propose a specific n x n matrix A, where n >= 3. Select four statements from the invertible matrix theorem and show that all four statements are true or false, depending on the matrix you selected. Make sure to clearly explain and justify your work. Also, make sure to label your statements using the notation used in the notes (e.g., part (a), part (f), etc.).
Theorem (The Invertible Matrix Theorem): Let A be an n x n matrix. Then the following statements are equivalent:
A is an invertible matrix.
A is row equivalent to the n x n identity matrix.
A has n pivot positions.
The equation Ax = 0 has only the trivial solution.
The columns of A form a linearly independent set.
The linear transformation x à Ax is one-to-one.
There is an n x n matrix C such that CA = I.
There is an n x n matrix D such that AD = I.AT is an invertible matrix.
Answer:
A) A is an invertible matrix ( TRUE )
B) A is a row equivalent to the n x n identity matrix ( n = 3 ) ( TRUE )
C ) The equation Ax = 0 has only the trivial solution ( TRUE )
D ) The columns of A form a linearly independent set ( TRUE )
Step-by-step explanation:
Assuming a matrix A
[tex]\left[\begin{array}{ccc}1&2&1\\-1&0&3\\4&1&5\end{array}\right][/tex]
det A = 1 [ 0 -3 ] + 2 [12 + 5 ] + 1[-1]
= -3 + 34 -1 = 30 ≠ 0
THEREFORE det A = 30 ≠ 0

You are thinking about the things that can go wrong on your trip home over the Thanksgiving break. You have booked a flight with US-Scareways. You know that in 33 percent of the cases the company has canceled the flight you were on. Should such a thing occur, there would be no other air travel option home for you. As a backup, your friend Walter has offered you a ride back. However, you know that Walter only has a seat in his car for you with 88 percent probability. What is the probability of you making it home for the holidays?
Answer:
0.9604 = 96.04% probability of you making it home for the holidays
Step-by-step explanation:
We have these following probabilities:
100 - 33 = 67% probability of the flight happening.
In the 33%, that is, when the flight does not happen, there is an 88% probability that you get the ride with Walter.
What is the probability of you making it home for the holidays?
0.67 + 0.88*0.33 = 0.9604
0.9604 = 96.04% probability of you making it home for the holidays

if sin B=8/17 WHAT IS TAN B?
Answer:
In first quadrant, [tex]\tan B=\frac{8}{15}[/tex]
In second quadrant, [tex]\tan B=\frac{-8}{15}[/tex]
Step-by-step explanation:
Given: [tex]\sin B=\frac{8}{17}[/tex]
To find: [tex]\tan B[/tex]
Solution:
Trigonometry explains the relationship between the sides and the angles of the triangle.
Here,
[tex]\sin B=\frac{8}{17}[/tex]
So, B can be in first or second quadrant as sine is positive both first and second quadrants.
Cosine and tangent are positive in first quadrant but negative in second quadrant.
In first quadrant:
[tex]\cos B=\sqrt{1-\sin ^2B}=\sqrt{1-\left ( \frac{8}{17} \right )^2}=\sqrt{1-\frac{64}{289}}=\sqrt{\frac{225}{289}}=\frac{15}{17}[/tex]
So, [tex]\tan B=\frac{\sin B}{\cos B}=\frac{\frac{8}{17}}{\frac{15}{17}}=\frac{8}{15}[/tex]
In second quadrant:
[tex]\cos B=-\sqrt{1-\sin ^2B}=-\sqrt{1-\left ( \frac{8}{17} \right )^2}=-\sqrt{1-\frac{64}{289}}=-\sqrt{\frac{225}{289}}=\frac{-15}{17}[/tex]
[tex]\tan B=\frac{\sin B}{\cos B}=\frac{\frac{8}{17}}{\frac{-15}{17}}=\frac{-8}{15}[/tex]

A vertical right circular cylindrical tank measures 20 ft high and 12 ft in diameter. It is full of liquid weighing 62.4 lb divided by ft cubed. How much work does it take to pump the liquid to the level of the top of the tank?
Answer:
Step-by-step explanation:
Work done is given as the product of force and distance.
The liquid in the cylindrical tank weighs 62.4 lb/ft^3.
This means that each ft^3 of the tank has 62.4 lb of the liquid.
To find the wight of the liquid in the entire tank, we multiply 62.4 by the volume of the cylindrical tank.
The volume of a cylinder is given as:
[tex]V = \pi r^2h[/tex]
where r is its radius and h is its height
The radius of the tank is 6 ft (since its diameter is 12 ft) and its height is 20 ft.
Therefore, the weight of the liquid in the tank is given as:
[tex]V = \pi * 6^2 * 20 = 2261.95 lb[/tex]
This weight is a force.
The height of the tank is 20 ft.
Therefore, the work done in pumping the liquid to the top of the tank is:
W = 2261.95 * 20 = 45239 ft.lb

Which of the following describes the translation of the graph of y = x 2 to
obtain the graph of y = -x 2 - 3?
reflect over the x-axis and shift left 3
reflect over the x-axis and shift down 3
reflect over the y-axis and shift down 3
Answer:
reflect over the x-axis and shift down 3
Step-by-step explanation:
The leading coefficient of -1 means the graph is reflected over the x-axis. The addition of -3 to the function means each graphed point is shifted down 3 units from the original.
The graph of y = -x^2 -3 is the result of the transformation ...
reflect over the x-axis and shift down 3
A company that produces fine crystal knows from experience that 17% of its goblets have cosmetic flaws and must be classified as "seconds." (Round your answers to four decimal places.)(a)Among seven randomly selected goblets, how likely is it that only one is a second
Answer:
0.3891 = 38.91% probability that only one is a second
Step-by-step explanation:
For each globet, there are only two possible outcoes. Either they have cosmetic flaws, or they do not. The probability of a goblet having a cosmetic flaw is independent of other globets. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
17% of its goblets have cosmetic flaws and must be classified as "seconds."
This means that [tex]p = 0.17[/tex]
Among seven randomly selected goblets, how likely is it that only one is a second
This is P(X = 1) when n = 7. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{7,1}.(0.17)^{1}.(0.83)^{6} = 0.3891[/tex]
0.3891 = 38.91% probability that only one is a second
In ΔKLM, the measure of ∠M=90°, MK = 2.7 feet, and KL = 6.6 feet. Find the measure of ∠L to the nearest degree.
Answer:
24.15° = 24° to the nearest degree
Step-by-step explanation:
If we draw the triangle we would see that the KL is the longest side and the hypothenus;
Also MK would-be the height and ML is the base of the triangle.
Since L and M are the angles at the base;
From Trigonometry Sin L = MK/ KL
= 2.7/6.6
L = Sin^{-1} (2.7/6.6)
L = Sin^{-1} (0.4091)
=24.15°
Note : sin a = height/ longest side
= Opposite/hypothenus

O -2.89
-0.69
O 1.63
0.61
O 0.60
Answer:
Option (2)
Step-by-step explanation:
Given in the question,
ln(3) = 1.10
ln(6) = 1.79
We have to calculate the value of ln(2).
Since ln(6) = ln(3 × 2)
= ln(3) + ln(2) [From the property of logarithm, ln(a×b) = ln(a) + ln(b)]
1.79 = 1.10 + ln(2)
ln(2) = 1.79 - 1.10
ln(2) = 0.69
Therefore, value of ln(2) will be 0.69.
Option (2) will be the answer.
