Solving for q will give us the optimal quantity that maximizes the profit, a function that gives the total profit earned can be written as:
Profit(q) = (Revenue per item - Cost per item) * q
Assuming that the revenue and cost are functions of the quantity sold (q), the total profit can be calculated as follows:
Profit(q) = Revenue(q) - Cost(q)
To find the quantity which maximizes the profit, we can take the derivative of the profit function with respect to q and set it equal to zero, and then solve for q:
Profit'(q) = Revenue'(q) - Cost'(q) = 0
Solving for q will give us the quantity that maximizes the profit. However, without knowing the specific forms of the revenue and cost functions, we cannot write a specific profit function or find the quantity that maximizes the profit.
In general, the profit function can be written as:
Profit(q) = (Revenue per item - Cost per item) * q
where the revenue per item and cost per item are functions of q. To find the quantity that maximizes the profit, we need to differentiate the profit function with respect to q and set it equal to zero:
Profit'(q) = Revenue'(q) - Cost'(q) = 0
Solving for q will give us the optimal quantity that maximizes the profit.

The profit for the new container would be 3.47 each.
The gain from any business operation is referred to as profit. Every time a merchant sells a product, his goal is to make
a profit by getting something from the customer. In other words, if he sells the goods for more than the cost price, he
makes a profit; yet, if he needs to sell them for less, he loses money.
To calculate the profit for the new container, you need to follow these steps:
Determine the selling price. The marketing team suggests that the proposed container will sell for 3.97.
Determine the additional cost to make the new container. It will cost an additional 0.50 each to make.
Calculate the profit. Subtract the additional cost from the selling price to find the profit for the new container.
Profit = Selling Price - Additional Cost
Profit = 3.97 - 0.50
Profit = 3.47

Answer:
y in (7,y) = 14
Step-by-step explanation:
A General Linear function is as the following:
y = mx + c, Where: m: slope of the line, c: y-intercept
Given that:
Point 1 (P1) = (1,5)
Point 2 (P2) = (3, 11)
Point 3 (P3) = (7,y)
By substituting in the linear function with P1:
5 = m + c ---> (1)
By substituting in the linear function with P2:
11 = 3m + c ---> (2)
By multiplying equation (1) times 3 and subtracting eq. (2) from it:
(15 = 3m + 3c) - (11 = 3m + c) =
4 = 2c
Then, c = 2
By substituting with "c" in eq. (1):
5 = m + 2
Then, m = 3
Hence,
the function of this line is:
y = 3x + 2
So,
to get "y" in P3, we are going to substitute with 7:
y = 3(7) + 2
then "y" in P3 = 23
Another Solution:
by getting the slope of the line:
[tex]Slope = \frac{\triangle y}{\triangle x}[/tex] Where: Δy: change in y points, Δx: change in x points
by utilizing P1 & P2 in slope formula:
[tex]slope = \frac{11 - 5}{3 - 1} = \frac{6}{2} = 3[/tex]
By substituting with P1 in the linear function:
5 = 3 + c
Then, c = 2
the function of the line is:
y = 3x + 2
So,
to get "y" in P3, we are going to substitute with 7:
y = 3(7) + 2
then "y" in P3 = 23

Express cos � L as a fraction in simplest terms.
Answer:
cos(L) = (√46)/11
Step-by-step explanation:
You want cos(L) in simplest terms, given right triangle side lengths LK=√46 and JK=√75.
CosineThe cosine is the ratio ...
Cos = Adjacent/Hypotenuse
The side adjacent to vertex L is LK. The hypotenuse of the triangle is LJ. This means the desired ratio is ...
cos(L) = LK/LJ
Pythagorean theoremThe length of hypotenuse LJ can be found using the Pythagorean theorem.
LJ² = LK² +JK²
LJ² = (√46)² +(√75)² = 46 +75 = 121
LJ = √121 = 11
RatioThen the desired ratio is ...

What is Algebraic expression ?
An algebraic expression is a mathematical phrase that can contain variables, constants, and operators (such as addition, subtraction, multiplication, and division) that are used to represent quantities and their relationships.
To solve the system using addition, we want to add the two equations together in a way that eliminates one of the variables. In this case, we can add the two equations directly because the x term will cancel out:
X - 4.7y = -9.1
+(-x + 5.8 = 12.4)
1.1y = 3.3
Now we can solve for y by dividing both sides by 1.1:
y = 3.3 ÷ 1.1
y = 3
Substituting y = 3 back into one of the original equations, we can solve for x:
x - 4.7y = -9.1
x - 4.7(3) = -9.1
x - 14.1 = -9.1
x = 5
Therefore, the solution to the system of equations is x = 5 and y = 3.

a sampling distribution is created using samples of the ages at which 48 children begin reading, what would be the mean of the sampling distribution of sample means? round to two decimal places, if necessary.
The mean of the sampling distribution of sample means is approximately 5.2 ± 0.1339.
When a sampling distribution is created using samples of the ages at which 48 children begin reading, the mean of the sampling distribution of sample means can be calculated by dividing the population mean by the square root of the sample size. This is known as the standard error of the mean and is denoted as SE.
The formula for calculating the standard error of the mean is:
SE = σ / √n
where σ is the population standard deviation and n is the sample size.In this case, the sample size is 48 children. Since the population standard deviation is not given, it is assumed that the sample standard deviation is used as an estimate of the population standard deviation. The formula for calculating the sample standard deviation is:
S = √[(Σ(x - μ)²) / (n - 1)]
where S is the sample standard deviation, Σ is the sum of the squared deviations from the mean, x is the value of each observation, μ is the mean of the sample, and n is the sample size.Using the data given, the sum of the squared deviations from the mean is:
Σ(x - μ)² = (6 - 5.2)² + (8 - 5.2)² + (7 - 5.2)² + (9 - 5.2)² + (4 - 5.2)² + (7 - 5.2)² + (6 - 5.2)² + (5 - 5.2)² = 2.56 + 5.76 + 1.44 + 12.96 + 1.44 + 1.44 + 0.36 + 0.04 = 26.4
The sample standard deviation is:S = √[26.4 / (48 - 1)] = 0.9197Using the formula for standard error of the mean, the mean of the sampling distribution of sample means is:

A path 2.5 M is running around a square field whose side is 45 M find area path
The area of the path running around the square field is 475 square meters.
To find the area of the path running around a square field with a side of 45 meters and a path width of 2.5 meters,
Calculate the area of the entire square (including the path):
Side of the larger square = 45 M (side of the field) + 2.5 M (width of the path on one side) + 2.5 M (width of the path on the opposite side) = 50 M
Area of the larger square = (Side of the larger square)²
= (50 M)²
= 2500 M²
Calculate the area of the square field (without the path):
Side of the field = 45 M
Area of the square field = (Side of the field)²
= (45 M)²
= 2025 M²
Subtract the area of the square field from the area of the entire square to find the area of the path:
Area of the path = Area of the larger square - Area of the square field
= 2500 M² - 2025 M²
= 475 M²

Franklin has a credit card with an APR of 28.2%. If he charges a purchase for $1,520, what is the estimated amount Franklin will pay in finance charges on that purchase?
The estimated amount Franklin will pay in finance charges on his $1,520 purchase is $35.07.
What is annual percentage rate?
Annual Percentage Rate (APR) is the annual rate charged for borrowing or earned through an investment and is expressed as a percentage that represents the actual yearly cost of funds over the term of a loan or investment.
The finance charges on a credit card purchase can be calculated using the following formula:
finance charges = (APR/365) * balance * number of days
Where APR is the annual percentage rate, balance is the amount of the purchase, and the number of days is the time period for which the finance charges are being calculated.
Assuming that Franklin does not make any payments towards his credit card balance during the billing period, the number of days for which finance charges will be calculated will be equal to the billing cycle. Let's assume a billing cycle of 30 days for this example.
Using the formula above, we can calculate the finance charges as follows:
finance charges = (28.2%/365) * $1,520 * 30
= (0.00077397) * $1,520 * 30
= $35.07 (rounded to the nearest cent)
Therefore, the estimated amount Franklin will pay in finance charges on his $1,520 purchase is $35.07.

The sample of one school may not be statistically significant or diverse enough to draw valid conclusions about the entire population of schools. The observation could be biased and may not provide a true representation of the overall situation. Therefore, it is important to use a larger and more diverse sample to draw more reliable conclusions.
