The website is advertising a 46% discount on the jacket, meaning that Farah will pay 46% less than the original price if she decides to buy it now.
A discount is a reduction in the original price of an item, allowing the customer to purchase it for less than the original price.
To calculate the discount mathematically, we can use the following formula:
Discounted price = Original price * (1 - discount percentage)
Let's assume the original price of the jacket is P dollars.
The discount percentage is 46%, which can be written as a decimal 0.46. To find the discounted price, we need to multiply the original price by (1 - discount percentage), which is (1 - 0.46) = 0.54.
So, the discounted price after the 46% saving will be P * 0.54 dollars.
In other words, Farah will pay 0.54 times the original price, P, to buy the jacket with the advertised 46% saving.

Find the coordinates of p so that p partitions segment ab in the part-to-whole ratio of 1 to 5 with a(-9, 3) and b(1, 8). Show your work for full credit. No work - no credit.
The following formula can be used to get the coordinates of P such that P divides segment AB into parts having a part-to-whole ratio of 1 to 5 with A(-9, 3) and B(1, 8). P = (1 - t)A + TB.
What is partitions segment?A line segment can be partitioned by splitting it up into the specified number of parts. To determine how many partitions there are in the line segment, add the two values in the ratio. In order for all database nodes to participate in query execution, segmentation seeks to divide data across them uniformly. The CREATE PROJECTION statement's hash segmentation clause allows you to specify segmentation. For distributed computing, partitioning describes the arrangement of data in each node.where A and B are the coordinates of the segment's two endpoints, P's position on the segment AB is represented by the scalar value t, and
The part-to-whole ratio in this situation is 1:5, thus t equals 1/6.
In order to change the values of A, B, and t in the formula, we do as follows:
P = (1 - 1/6)A + (1/6)B
P = (5/6)A + (1/6)B
P = (-95/6, 35/6) + (1/6, 8/6)
P = (-15/2, 5/2) + (1/6, 4/3)
P = (-15/2 + 1/6, 5/2 + 4/3)
P = (-30/3, 23/6)
The positioning of P is (-10,3.83)
Regarding the second issue,
Using the same procedure as before, we can determine P's coordinates such that P divides segment AB in three equal halves if A(7, -4) and
B(-5, 4).
P = (1 - t)A + TB
The part-to-whole ratio in this situation is 3:1, therefore t equals 3/4.
In order to change the values of A, B, and t in the formula, we do as follows:
P = (1 - 3/4)A + (3/4)B
P = (1/4)A + (3/4)B
P = (7/4, -4/4) + (-53/4, 43/4)
P = (7/4 + -15/4, -4/4 + 3)
P = (-8/4, -1/4)
The positioning of P is (-2,-0.25)
Point P in the first issue is hence (-10,3.83), while Point P in the second issue is (-2,-0.25)

x is gamma, what is cx
"cX" is a function that takes two inputs and returns a scalar result and the value of "cX" depends on the values of the scalar "c" and the constant X.
Gamma (Γ) is a mathematical constant that is used in various areas of mathematics, including probability theory, statistics, and engineering.
The symbol "c" is a constant that represents a scalar multiplier in mathematics. This means that when you multiply a value by "c", you are multiplying it by a constant number. In this case, when we say "cX", we are multiplying the value of X (which is gamma) by the constant "c".
So, in mathematical terms, the expression "cX" can be defined as a function that takes a scalar value (c) and a constant value (X = gamma) as inputs, and returns a scalar result. This function can be used to determine the value of "cX" for a given value of "c".
It is important to note that the value of "cX" depends on the value of the scalar "c". For example, if "c" is equal to 2, then "cX" would be equal to 2 times the value of gamma.
On the other hand, if "c" is equal to 0.5, then "cX" would be equal to 0.5 times the value of gamma.
Complete Question:
Show that if X is gamma distributed and c(> 0) is a constant, then cX is gamma distributed. In particular, if X is chi-squared distributed, then cX is gamma distributed.

when constructing an inscribed square by hand, which step comes after constructing a circle? (1 point)
Constructing the four lines that intersect the circumference of the circle and form the square.
How to construct a circle inscribed in a square?To construct a circle inscribed in a square, first draw a square with the desired side length.
Next, draw two diagonals from opposite corners of the square. This will divide the square into four quadrants. Measure the length of each diagonal.
Divide the length of each diagonal by two and mark the midpoints of each diagonal.
This will create four points which will define the circle. Connect each of the midpoints with a curved line to form a circle inscribed in the square.
Finally, use a compass to adjust the curve of the circle until it is perfectly symmetrical.

An entrepreneur buys some hockey pucks. Each one costs $5.60 and resells for 7.84. What is the mark up price, as a percentage
The percentage mark up of the hockey is 40%
How to determine the percentage mark upFrom the question, we have the following parameters that can be used in our computation:
Selling = 7.84 and cost = 5/60
The markup price can be calculated as follows:
markup price = (selling price - cost price) / cost price * 100%
So, we have
markup price = (7.84 - 5.60) / 5.60 * 100%
Evaluate
markup price = 40%
So, the mark up price is 40%.

What’s the function of this?
Answer:
g(x) = 2x +1
Step-by-step explanation:
You want the complete table and the linear function that describes it, given the points (x, g(x)) = (-3, -5) and (-1, -1).
DifferencesWe note the differences between the x-values shown are -1 -(-3) = 2. The corresponding differences between those y-values is -1 -(-5) = 4.
This lets us fill in the values for x=1 and x=3 as being -1+4 = 3, and 3+4 = 7
We observe that the missing x-value corresponds to g(x)=1, which is halfway between g(x)=-1 and g(x)=3. That means its corresponding x-value will be halfway between x=-1 and x=1, at x=0.
The table is shown in the attachment.
Slope-intercept equationThe change in g(x) being 4 when the change in x is 2 means the slope is 4/2 = 2. The y-value of 1 when x=0 means the y-intercept is 1.
These are used to write the slope-intercept form of the equation:
y = mx +b . . . . . . slope is m, y-intercept is b
For a slope of 2 and a y-intercept of 1, the equation is ...
y = 2x +1
When we write that in "functional form", the expression g(x) replaces y:
g(x) = 2x +1
3.) A caterer charges $120 to cater a party for 15 people and $200 for 25 people. A.) Write an equation using x and y to find the cost of having a party catered depending on the number of people attending. B.) Describe what the x and y variables represent in your equation. C.) Use your equation to predict how much it will cost to have a party of 40 people catered. Show your work.
Answer: A) The equation can be written as y = mx + b, where m is the slope and b is the y-intercept. The slope represents the cost per person and the y-intercept represents the fixed cost. Using the two given points, we can find the slope and y-intercept:
(15, 120) and (25, 200)
m = (200 - 120) / (25 - 15) = 80 / 10 = 8
b = 120 - 8 * 15 = 120 - 120 = 0
So the equation is y = 8x.
B) In the equation y = 8x, x represents the number of people attending the party and y represents the cost of having the party catered.
C) To predict the cost of having a party of 40 people catered, we plug in x = 40 into the equation:
y = 8x
y = 8 * 40
y = 320
So it will cost $320 to have a party of 40 people catered.

for what value(s) of h is b in the plane spanned by a1 and a2?
The value of h for which b is in the plane spanned by a1 and a2 is -17
If the plane is spanned by a1 and a2 and if y is in the plane, then y is a linear combination of a1 and a2.
y = x(a1) + y(a2), where x and y are constants.
[4, 1, h] = x[1, 4, -2] + y[-2, -3, 7]
[4, 1, h] = [x - 2y, 4x -3y, -2x+ 7y] .
Vectors are equal if their corresponding components are equal:
So, x - 2y = 4, 4x - 3y = 1 and -2x + 7y = h
We can solve for x and y from the first two equations to find h:
x = -2
y = -3
h = -17
The question is incomplete, the complete question is
"For what value(s) of h is b in the plane spanned by a1 and a2?
a1 = [1, 4, -2] a2 = [-2, -3, 7] b = [4, 1, h]"
