Emily buys a shirt that originally costs $54. The price is marked down by 15% due to a sale, but Emily has a coupon for an additional 10%. How much did Emily pay for the shirt?
Answers
Emily has to pay $41.31 for the shirt after adding coupon and discount.
How to find the Cost Price (CP) of any discounted item?
Lets say CP = 54 and the discount is of 15% i.e. marked price
So, Marked Price= 85% of CP = 45.9
Lets apply the additional coupon of 10% on Marked Price.
Therefore, the payment amount = 90% of MP
payment amount = $41.31

Answer:
I will go with Henry
Step-by-step explanation:
To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this?
Answers
Henry could only see one line since both lines had the same slope, which means that the graphs of both equations will be identical and hence overlap.
Identify the linear equation?Linear equations in a system 3x + 2y = 4, and 9x + 6y = 12
We must demonstrate why Henry could only make out one line when he plotted the equations 3x-2y=4 and 9x-6y=12 on a graph.
Take the provided linear equation system into consideration.
3x - 2y = 4 ................(1)
9x - 6y = 12 ..................(2)
Due to the fact that equation (2) is a multiple of equation (1), 3 (3x - 2y = 4) = 9x - 6y = 12
The slopes of the provided equations are also same.
Difference with regard to x for equation (1) yields,
additional to equation (2),
With regard to x, we can differentiate to get,
The graphs of both equations will overlap since both lines have the same slope and hence have the same appearance on the graph.

Explain how you can solve inequality-2x +4 <16
Answers
The solution to the inequality -2x + 4 < 16 is x > -6.
To solve the inequality -2x + 4 < 16, you can follow these steps:
Start by isolating the variable term. In this case, the variable term is -2x. Move the constant term, which is +4, to the other side of the inequality by subtracting 4 from both sides:
-2x + 4 - 4 < 16 - 4
-2x < 12
Next, divide both sides of the inequality by the coefficient of x, which is -2. It's important to note that when you divide or multiply an inequality by a negative number, you need to reverse the direction of the inequality sign:
(-2x) / -2 > 12 / -2
x > -6
The solution to the inequality is x > -6. This means that any value of x greater than -6 would satisfy the original inequality. Graphically, this represents all the numbers to the right of -6 on the number line.
So, the solution to the inequality -2x + 4 < 16 is x > -6.

the transformation that includes a reflection of f(x) = (x - 1)² + 1 over the y-axis is f'(x) = 0.3((x - 1)² + 1).
Why it is?
The transformation that includes a reflection of f(x) = (x - 1)² + 1 over the y-axis is the transformation of the form f'(x) = f(-x) that replaces x with -x in the original function f(x).
Let's examine the answer choices:
a. f'(x) = 3((x - a)² + 1) does not involve a reflection over the y-axis, so it is not the correct transformation.
b. f'(x) = (0.1x - 1)² + 1 does not involve a reflection over the y-axis, so it is not the correct transformation.
c. f'(x) = (-4x - 1)² + 1 involves a reflection over the y-axis because the coefficient of x is negative. However, this transformation does not preserve the vertex of the parabola (which is at x = 1 in the original function), so it is not the correct transformation.
d. f'(x) = 0.3((x - 1)² + 1) involves a reflection over the y-axis because it is of the form f'(x) = f(-x) where f(x) = (x - 1)² + 1. In this transformation, the coefficient of (x - 1)² is multiplied by 0.3, so the graph of f'(x) is compressed horizontally by a factor of 0.3. The vertex of the parabola is still at x = 1, so the transformation preserves the vertex. Therefore, the correct answer is (d).
Thus, the transformation that includes a reflection of f(x) = (x - 1)² + 1 over the y-axis is f'(x) = 0.3((x - 1)² + 1).

how many independent variables are in a 2x3x2 factorial design
Answers
A 2x3x2 factorial design has three independent variables. What is a factorial design? A factorial design is an experimental design that studies the impact of two or more independent variables on a dependent variable.
The notation of a factorial design specifies how many independent variables are used and how many levels each independent variable has. In a 2x3x2 factorial design, there are three independent variables, with the first variable having two levels, the second variable having three levels, and the third variable having two levels.
The number of treatments or conditions required to create all feasible combinations of the independent variables is equal to the total number of cells in the design matrix, which can be computed as the product of the levels for each factor.
In this case, the number of cells would be 2x3x2=12.Therefore, a 2x3x2 factorial design has three independent variables and 12 treatment groups..

When we say ‘the limit does not exist’, do we mean it is actually in a determinate form or it is defined (like it's not something divided by zero)? If not, what is the basic meaning of ‘the limit does not exist’?
Answers
The limit does not exist if the graph features a vertical asymptote with one side going toward infinity and the other toward negative infinity.
What is meant by negative infinity?Since the graph is infinitely negative as one approaches zero from either side, the limit as x approaches zero would be negative infinity: In general, the limit will reach infinity or negative infinity when you take a limit and the denominator is equal to zero (depending on the sign of the function). The set of real numbers does not include infinity. The real number set is closed under addition and multiplication, which is one of its axioms. That is, you will always obtain a real number if you add two real numbers together. However, the closure rule is broken by the expressions ∞+(−∞) And ∞×0 for which there is no valid definition.To learn more about negative infinity, refer to:

g (b) show that among a group of 621 people, there are at least 21 who are born on the same day of the month (e.g., the 21st or the 12th, etc.). is the same fact true if there are only 620 people?
Answers
There would be 20 more of us (620-600). There would have been a day when more than 20 people would have been born.
A counting-based argument is known as a combinatorial argument or combinatorial proof. This line of reasoning has already been used, for instance in the section on Stirling numbers of the second sort.
It is mentioned that 620 persons shared the same month of birth. Assume that there were 30 days in the month to avoid losing generality. We'll demonstrate that through contradiction, assuming there were no more than 20 births on any one day throughout that month.
(Beyond that, we have the outcome.)
Now within Thirty Days, 30 * 20 births made up the total. However, since the population was 621 strong, another 21 persons had to be born on a day within that month. Note that the pigeon-hole principle was used in this instance. As a result, someday x, more than twenty people will be born. Consequently, there are at least 21 people who share a birthday.
The outcome would be the same whether there were 620 people. The discussion we had led to this. Keep in mind that in this scenario, we would have 20 more people (620-600). Therefore, a day when more than 20 people were born would have come.

You have a bag of poker chips, containing 2 white, 1 red, and 3 blue chips. White chips are worth $1, red chips are worth $3 and blue chips are worth $5. You need $7 worth of chips in order to see someone’s raise, so you take chips out of the bag one at a time, noting the color of each one as it’s removed, and stop when the total value of the chips removed is at least $7. How many sequences of chip colors are possible when you do this?
Answers
There are 144 possible sequences of chip colors.
How many sequences of chip colors are possibleWe can solve this problem by counting the number of possible sequences of chip colors that can be drawn from the bag until the total value of the chips is at least $7.
Let's consider all the possible sequences of chips that can be drawn from the bag. The first chip can be any of the 6 chips in the bag. For each chip color, there are different scenarios that can happen after drawing the first chip:
If the first chip is a white chip, then we need to draw chips worth $6 more in order to reach $7. We can draw any combination of the remaining 5 chips to get a total value of $6 or more. There are 2 white, 1 red, and 3 blue chips remaining, so there are 2^5 = 32 possible combinations.If the first chip is a red chip, then we need to draw chips worth $4 more in order to reach $7. We can draw any combination of the remaining 5 chips to get a total value of $4 or more. There are 2 white, 1 red, and 3 blue chips remaining, so there are 2^5 = 32 possible combinations.If the first chip is a blue chip, then we need to draw chips worth $2 more in order to reach $7. We can draw any combination of the remaining 5 chips to get a total value of $2 or more. There are 2 white, 1 red, and 2 blue chips remaining, so there are 2^4 = 16 possible combinations.Therefore, the total number of possible sequences of chip colors that can be drawn from the bag until the total value of the chips is at least $7 is: 2 x 32 + 1 x 32 + 3 x 16 = 144

What is the Area of a Sector?The area of a sector of a circle = ∅/360 × πr².
We are given that:
Area of the sector = 40π
Radius (r) = 12 units
∅ = n°
Plug in the values and solve for n
40π = n/360 × π(12²)
40π = n/360 × π144
Divide both sides by 144π
40π/144π = n/360 × 144π/144π

Answers
A) Function is increasing on (-∞, -1) and (7/2, ∞), and decreasing on (-1, 7/2).
b) The local minimum value of f is; 5608/2197 at x = -42/13, and the local maximum value of f is 139/8 at x = 7/2.
(a) To determine the intervals on which f is increasing or decreasing, we need to determine the critical points and then check the sign of the derivative on the intervals between them.
f(x)=8x³-42x-48x + 4
f'(x) = 24x² - 90
Setting f'(x) = 0, we get
24x² - 90 = 0
24x² = 90
x =± √3.75
So, the critical points are;
x = -1 and x = 7/2.
We can test the sign of f'(x) on the intervals as; (-∞, -1), (-1, 7/2), and (7/2, ∞).
f'(-2) = 72 > 0, so f is increasing on (-∞, -1).
f'(-1/2) = -25 < 0, so f is decreasing on (-1, 7/2).
f'(4) = 72 > 0, so f is increasing on (7/2, ∞).
Therefore, f is increasing on (-∞, -1) and (7/2, ∞), and decreasing on (-1, 7/2).
(b) To determine the local maximum and minimum values of f, we need to look at the critical points and the endpoints of the interval (-1, 7/2).
f(-1) = -49
f(7/2) = 139/8
