Paula bought a ski jacket on sale for $8 less than half its original price. She paid $84 for the jacket. What was the original price?
The original price of the ski jacket is $184.
What is price?
The sum of money paid or the amount of compensation offered by one party to another in exchange for goods or services is known as a price. The cost of production can take on different names depending on the circumstance. If the item is a "good" in a commercial transaction, the cost of the item will probably be referred to as its "price".
Given:
Paula bought a ski jacket on sale for $8 less than half its original price.
She paid $84 for the jacket.
We have to find the original price of the ski jacket.
Let
The original price = x
The amount she bought it = x/2 - 8
She paid $84 for the jacket
Therefore,
84 = x/2 - 8
Add 8 on both sides,
84 + 8 = x/2 - 8 + 8
92 = x/2
x = 184
Hence, the original price of the ski jacket is $184.

given a customer initially purchased calluge, the probability that this customer purchases calluge on the second purchase is
The probability that the customer purchases calluge on the second purchase, given that they purchased it on the first purchase, is:
P(C2|C1) = p
The customer's behavior is independent from purchase to purchase, and the probability of purchasing calluge remains constant, then we can use the concept of conditional probability to calculate the probability that the customer purchases calluge on the second purchase, given that they purchased it on the first purchase.
Let P(C1) be the probability that the customer purchased calluge on the first purchase, and let P(C2|C1) be the conditional probability that the customer purchases calluge on the second purchase, given that they purchased it on the first purchase.
If we assume that the probability of purchasing calluge remains constant and is denoted by p, then we have:
P(C1) = p
Since the customer has already purchased calluge on the first purchase, the probability of purchasing it again on the second purchase depends on whether the customer is more likely to purchase it again or switch to another product.
If we assume that the customer's behavior is independent from purchase to purchase, then the probability of purchasing calluge on the second purchase is also p.
If we assume that the probability of purchasing calluge remains constant and the customer's behavior is independent from purchase to purchase, then the probability that the customer purchases calluge on the second purchase, given that they purchased it on the first purchase, is equal to the probability that they purchased calluge on the first purchase, which is denoted by p.

We cannot determine the probability that a customer who initially purchased Calluge will purchase Calluge on the second purchase without additional information.
The probability that a customer who initially purchased Calluge will purchase Calluge on the second purchase can be calculated using the concept of conditional probability. Let P(A) represent the probability of an event A occurring and P(B|A) represent the probability of an event B occurring given that event A has occurred.
Let us assume that P(C) represents the probability of a customer purchasing Calluge on the second purchase, given that they have already purchased Calluge on the first purchase. This can be written as P(C|C).
We can use Bayes' theorem to calculate P(C|C). Bayes' theorem states that:
P(C|C) = P(C and C)/P(C)
Here, P(C and C) represents the probability of a customer purchasing Calluge on both the first and second purchases, and P(C) represents the probability of a customer purchasing Calluge on the first purchase.
Since we are given that a customer initially purchased Calluge, we can assume that P(C) = 1 (i.e., the probability of purchasing Calluge on the first purchase is 1).
Now, we need to find the probability of a customer purchasing Calluge on both the first and second purchases, which can be written as P(C and C) or P(C)^2. However, we do not have any information about the probability of a customer purchasing Calluge on both the first and second purchases.
Therefore, we cannot determine the probability that a customer who initially purchased Calluge will purchase Calluge on the second purchase without additional information.

how to know if a function has a vertical asymptote
To determine if a function has a vertical asymptote, you need to consider its behavior as the input approaches certain values.
A vertical asymptote occurs when the function approaches positive or negative infinity as the input approaches a specific value. Here's how you can determine if a function has a vertical asymptote:
Check for restrictions in the domain: Look for values of the input variable where the function is undefined or has a division by zero. These can indicate potential vertical asymptotes.
Evaluate the limit as the input approaches the suspected values: Calculate the limit of the function as the input approaches the suspected values from both sides (approaching from the left and right). If the limit approaches positive or negative infinity, a vertical asymptote exists at that value.
For example, if a rational function has a denominator that becomes zero at a certain value, such as x = 2, evaluate the limits of the function as x approaches 2 from the left and right. If the limits are positive or negative infinity, then there is a vertical asymptote at x = 2.
In summary, to determine if a function has a vertical asymptote, check for restrictions in the domain and evaluate the limits as the input approaches suspected values. If the limits approach positive or negative infinity, there is a vertical asymptote at that value.

At the beginning of the day, stock xyz opened at 4. 25$. At the end of the day, it closed at $5. 25. What is the rate of change of stock xyz
Answer:At the beginning of the day, stock XYZ opened at $4.25. At the end of the day, it closed at $5.25. The rate of change of stock XYZ is 23.5%. The correct option is (A).
What is rate of change in stock?
By subtracting the price of a security at time B from the price of the same security at time A and dividing the result by the price at time A, the price rate of change can be calculated.
The indicator is a technical analysis tool that measures unbounded velocity versus a zero-level middle.
The calculation for percentage change is 100 divided by (New Price - Old Price). If the stock price has increased, the percentage change will be positive; if the stock price has decreased, it will be negative.
Therefore, at the beginning of the day, stock XYZ opened at $4.25. At the end of the day, it closed at $5.25. The rate of change of stock XYZ is 23.5%.

The area of the rectangle in terms of b is 11b - b², and the perimeter is always 22, regardless of the value of b.
What is rectangle?A rectangle is a four-sided flat shape with opposite sides that are equal in length and parallel to each other. It has four right angles (90-degree angles) at each corner. The two sides that are parallel to each other are called the length, and the other two sides are called the width.
The area of a rectangle is found by multiplying its length and width, and its perimeter is the sum of the lengths of all four sides. Rectangles are common in everyday life and can be found in many different contexts, such as books, doors, windows, and electronic screens.
According to given information,
Let's assume that the length of the rectangle is 'l' and the width is 'b'.
The area of a rectangle is given by the formula A = lb, where A is the area, l is the length, and b is the width.
The perimeter of a rectangle is given by the formula P = 2(l + b), where P is the perimeter, l is the length, and b is the width.
So, the area of the rectangle is:
A = lb = 28
And the perimeter of the rectangle is:
P = 2(l + b) = 40
P = (l+b) = 20
l= 20 -b
Now, we can substitute l = 20 - b into these formulas:
A = (20 - b)b
P = 2(20 - b + b)
Simplifying, we get:
A = 40b - b²
P= 40
So, the area of the rectangle in terms of b is 11b - b², and the perimeter is always 22, regardless of the value of b.

What is rectangle?
A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
The longer parallel sides are called length(l) and two shorter sides are called breadth(b).
Perimeter of a rectangle is 2(l+b).
Area of rectangle is l*b.
2(l+b)=28
L+b=28/2=14
L=14-b .....eq(1)
L*b=40
(14-b)b=40
14b-b^2=40
b^2-14b+40=0
b^2-10b-4b+40=0
b(b-10)-4(b-10)=0
(b-10)(b-4)=0
Either b=10 or b=4
If b=10 then l =4 but length can't be shorter than the breadth so b=4cm and l=10 cm is the answer.

Answer:
The correct system of equations to find the price of a hamburger (h) and the price of an order of french fries (f) is:
3h + 4f = 22.75
2h + f = 11
Step-by-step explanation:
Here's how you can solve this system of equations step by step:
Write the two given equations:
3h + 4f = 22.75
2h + f = 11
Solve one of the equations for one of the variables. Let's solve the second equation for h:
h = 11 - f
Substitute the expression we found for h into the first equation:
3 (11 - f) + 4f = 22.75
Simplify the equation:
33 - 3f + 4f = 22.75
Combine like terms:
33 = 22.75
Solve for f:
f = (33 - 22.75) / 4 = 5.25
Use the expression we found for f to find h:
h = 11 - f = 11 - 5.25 = 5.75
So, the price of a hamburger is $5.75 and the price of an order of french fries is $5.25.

It is known that the length of a certain product x is normally distributed with μ = 18 inches. How is the probability p(x > 18) related to p(x < 18)?
The probability of x being greater than 18 (p(x > 18)) is equal to the probability of x being less than 18 (p(x < 18)) in a normal distribution.
In a normal distribution, the probability of an event happening to the left of the mean (μ) is equal to the probability of the event happening to the right of the mean. This means that if we know the probability of x being less than 18 (p(x < 18)), we can use the property of symmetry to determine the probability of x being greater than 18 (p(x > 18)).
Since the probability distribution of x is symmetric around the mean, the area under the probability density function (PDF) to the left of the mean is the same as the area to the right of the mean. Therefore, we can say:
p(x > 18) = p(x < 18)
In other words, the probability of x being greater than 18 is equal to the probability of x being less than 18 in a normal distribution.

how to find the exact value of a trig function
The exact value of a trig function can be found by using the unit circle, the trigonometric identities, tables or a calculator.
How to find the exact value of a trig function?To find the exact value of a trigonometric function, there are several methods you can use. Below are a few:
1. Using the Unit Circle: The unit circle is a circle with radius 1 centered at the origin in the coordinate plane. The angles in the unit circle are measured in radians and the coordinates of points on the circle can be used to find the exact values of trigonometric functions. For example, given an angle θ in the unit circle, the x-coordinate of the point on the circle corresponding to θ is cos(θ) and the y-coordinate is sin(θ).
2. Using the Trigonometric Identities: There are several trigonometric identities that relate the values of the six trigonometric functions to one another. These identities can be used to find the exact value of a trigonometric function for certain angles. For example, the Pythagorean identity states that for any angle θ, sin²(θ) + cos²(θ) = 1.
3. Using Tables or a Calculator: Trigonometric tables or a scientific calculator can be used to find the exact values of trigonometric functions for certain angles. The values are often given in degrees, so it is important to convert the angle to radians if necessary.

The stream velocity has no influence on the amount of dissolved load it contains. The amount of dissolved material depends on erosion and deposition carried out in the watercourse. These are affected by factors such as the slope of the land, the resistance of the material to erosion, the size of the sediments transported, etc.
Which of the following is not influenced by stream velocity?Dissolved loadStream velocity plays an important role in the transport of sediments and dissolved loads in a watercourse. It affects the erosion and deposition processes that occur in the watercourse, which in turn affect the amount of sediment and dissolved load that is carried by the stream. For example, faster stream velocities can cause more erosion of the stream bed, leading to more material being carried in the water.
Sediment is any particulate matter that is transported by a fluid, and it can come in many different forms. The three main types of sediment are:
The suspended load is made up of small particles that are carried along in the water column. The bed load consists of larger particles that are moved along the bottom of the streambed.

please also explain the steps
Answer:
Step-by-step explanation:
Okay, so assuming you have set up your division problem, you first have to find a value that will set x = to x^3. This value is x^2. So, put that above the division symbol. Next, multiply (x +4) by x^2. Then, subtract that answer from x^3 + x^2. You should get -3x^2 - 10x. Then, find a value to get x to -x^2. This value is -3x. So, put that above the division symbol. Multiply (x + 4) by -3x. Then, subtract that value from -3x^2 - 10x. You should get 2x + 8 as your answer. Now find a value to get x to 2x. 2 should work. So, put that above the division symbol. Multiply (x +4) by 2. When subtract your answer from 2x + 8 you get 0. Therefore, the answer is x^2 - 3x +2. Hope this helps!!
