Given parameters:
Cost of paint per month = $320
Cost of quality plain shirts = $9 each
Selling price = $24
Rent per month = $100
Unknown:
Number of shirts Sam has to sell to break even = ?
Solution :
Let the number of shirt sold each month = y
To break even the cost price per shirt must be equal to the selling price;
i.e;
Cost price = selling price at break even point;
Cost price = Cost of paint + Cost of quality plain shirt + Cost of rent
= 320 + 9y + 100
= 420 + 9y
Selling price = 24y
To break even;
420 + 9y = 24y
420 = j24y - 9y
420 = 15y
y = \(\frac{420}{15}\) = 28
To break even, Sam must sell 28 shirts in a month.
Three trucks are being loaded with small, medium, and large crates. each crate of the same size has the same weight, and each size has a different weight
The weight distribution can vary based on the number of crates and their sizes. It's important to consider the weight of each size and evenly distribute the crates to ensure the trucks are loaded properly.
The three trucks are being loaded with small, medium, and large crates. Each crate of the same size has the same weight, and each size has a different weight.
The weight of the crates is dependent on their size. Let's say the small crates weigh 10 pounds, the medium crates weigh 20 pounds, and the large crates weigh 30 pounds.
To load the trucks, you need to consider the weight distribution. If you want to evenly distribute the weight, you can load the same number of crates of each size onto each truck.
For example, if you have 10 small, 10 medium, and 10 large crates, you can load 3 small, 3 medium, and 3 large crates onto each truck.
However, if you have a different number of crates for each size, you will need to adjust the distribution accordingly. Let's say you have 10 small, 5 medium, and 15 large crates.
In this case, you can calculate the total weight of each size by multiplying the weight of one crate by the number of crates.
Then, you can divide the total weight of each size by the total number of trucks to determine how many crates of each size should be loaded onto each truck.
For example, if the total weight of the small crates is 100 pounds, the total weight of the medium crates is 100 pounds, and the total weight of the large crates is 450 pounds, and you have 3 trucks, you can divide the total weight by the number of trucks.
This means each truck should carry approximately 33 pounds of small crates, 33 pounds of medium crates, and 150 pounds of large crates.
Remember, the weight distribution can vary based on the number of crates and their sizes.
It's important to consider the weight of each size and evenly distribute the crates to ensure the trucks are loaded properly.

What is the probability of NOT drawing a face card from a standard deck of 52 cards.
8 over 13
3 over 13
10 over 13
1 half
The probability of NOT drawing a face card from a standard deck of 52 cards is 10 over 13.
First determine the total number of face cards and non-face cards in a standard deck of 52 cards. In a standard deck, there are 12 face cards (3 face cards per suit: Jack, Queen, and King, and 4 suits: Hearts, Diamonds, Clubs, and Spades). This means there are 52 - 12 = 40 non-face cards.
Now, we'll calculate the probability of NOT drawing a face card:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
Probability of NOT drawing a face card = (Number of non-face cards) / (Total number of cards)
Probability = 40 / 52
Simplify the fraction by dividing the numerator and denominator by their greatest common divisor (4):
Probability = (40/4) / (52/4)
Probability = 10 / 13
So, the probability of NOT drawing a face card from a standard deck of 52 cards is 10/13. Your answer: 10 over 13.

If Tri-County has 1,000,000MW h of demand from its customers (other than Boulder), what will Tri-County have to charge to break even? Tri-County wit have to charge? to break oven. (Enter your response rounded to the nearest penny.)
Tri-County will have to charge approximately $83.1 per MWh to break even.
To calculate the break-even price that Tri-County will have to charge to cover its costs, we need to consider both the fixed costs and the variable costs. The fixed costs are given as $80.1 million per year.
The variable costs are calculated by multiplying the quantity of electrical power sold (150,000 MWh per year to Boulder) by the variable cost per MWh ($20). Therefore, the variable costs amount to 150,000 MWh/year * $20/MWh = $3 million per year.
To cover both fixed and variable costs, Tri-County needs to charge a total amount that equals the sum of these costs. The total cost is $80.1 million + $3 million = $83.1 million per year.
Now, let's calculate the break-even price per MWh. Since Tri-County has a demand of 1,000,000 MWh from its customers (other than Boulder), we can divide the total cost by this quantity to find the break-even price.
Break-even price = Total cost / Quantity of electrical power demanded
Break-even price = $83.1 million / 1,000,000 MWh = $83.1/MWh
Therefore, Tri-County will have to charge approximately $83.1 per MWh to break even.

Reflection over the (x-axis/origin/y-axis); (transformation/translation/dilation/movement upwards) with a scale factor of 0.4; translation 8 units left and ___ units up.
Answer:
reflection over the y-axis; dilation with a scale factor of 0.4; translation 8 units left and 8 units upStep-by-step explanation:
ReflectionThe first transformation changes the sign of the x-coordinate. That means a point that was some number of units (3, for example) right of the y-axis will be transformed to a point 3 untis left of the y-axis. It is reflected across the y-axis.
__
DilationThe second transformation multiplies each coordinate value by 0.4. A point that was some number of units (3, for example) away from the origin, will be transformed to a point 3×0.4 = 1.2 units from the origin. It is dilated by a factor of 0.4.
__
TranslationThe third transformation subtracts 8 from the x-coordinate and adds 8 to the y-coordinate. The x-coordinate is a measure of the distance to the right of the y-axis, so subtracting 8 from the x-coordinate means the point is 8 fewer units to the right of the y-axis. It is translated left 8 units.
Similarly, the y-coordinate is a measure of the distance up from the x-axis. Adding 8 to the y-coordinate will move the point 8 more units up from the x-axis. It is translated up 8 units.

A store recently released a new line of alarm clocks that emits a smell to wake you up in the morning. The head of sales tracked buyers' ages and which smells they preferred. The probability that a buyer is an adult is 0.9, the probability that a buyer purchased a clock scented like cotton candy is 0.9, and the probability that a buyer is an adult and purchased a clock scented like cotton candy is 0.8. What is the probability that a randomly chosen buyer is an adult or purchased a clock scented like cotton candy?
The probability that a randomly chosen buyer is an adult or purchased a clock scented like cotton candy is 1, which is equivalent to 100%.
To find the probability that a randomly chosen buyer is an adult or purchased a clock scented like cotton candy, we can use the concept of probability union.
Let A be the event that a buyer is an adult and C be the event that a buyer purchased a clock scented like cotton candy.
We are given:
P(A) = 0.9 (probability that a buyer is an adult)
P(C) = 0.9 (probability that a buyer purchased a clock scented like cotton candy)
P(A and C) = 0.8 (probability that a buyer is an adult and purchased a clock scented like cotton candy)
The probability of the union of two events A and C is given by:
P(A or C) = P(A) + P(C) - P(A and C)
Substituting the given values:
P(A or C) = 0.9 + 0.9 - 0.8
P(A or C) = 1.8 - 0.8

Solve the following linear program: Identify the optimal solution.
Minimize C = 3x + 4y
Subject to:
3x - 4y<= 12 A
x + 2y>= 4 B
x>= 1 C
x, y >= 0
The optimal solution of the given linear program is (x, y) = (2, 1).
How to solve linear programming problems?
To solve the linear program, we first plot the feasible region determined by the constraints:
3x - 4y <= 12Ax + 2y >= 4x >= 1x, y >= 0We can rewrite the second constraint as y >= (4 - Ax)/2.
Next, we plot the lines 3x - 4y = 12 and Ax + 2y = 4 - 2x and shade the appropriate regions:
3x - 4y = 12 => y <= (3/4)x - 3Ax + 2y = 4 - 2x => y >= (4 - Ax)/2We can see that the feasible region is bounded, so we can find the optimal solution by evaluating the objective function C at each of the corner points of the feasible region.
The corner points are:
(1, 0)(2, 0)(8/3, -3/4)(4, 0)(3, 1/2)(2, 1)Evaluating C at each corner point, we get:
(1, 0) => C = 3(1) + 4(0) = 3(2, 0) => C = 3(2) + 4(0) = 6(8/3, -3/4) => C = 3(8/3) + 4(-3/4) = 4(4, 0) => C = 3(4) + 4(0) = 12(3, 1/2) => C = 3(3) + 4(1/2) = 10.5(2, 1) => C = 3(2) + 4(1) = 11Thus, the optimal solution is at (2, 1) with a minimum value of C = 11.

Is the union of countably infinite sets countable?
The answer is that it depends on the specific countable sets being considered and how they are being combined.
The union of countably infinite sets can be countable, as in the case of the union of all positive integers and all negative integers, which is also countable.
However, the union of countably infinite sets can also be uncountable. For example, consider the union of all the intervals [n, n+1) for n = 1, 2, 3, .... Each of these intervals is countable (since it contains all the real numbers between two integers, which is a countable set), but the union of these intervals is the uncountable set of all real numbers greater than or equal to 1. Therefore, the union of these countably infinite sets is uncountable.
So the answer is that it depends on the specific countable sets being considered and how they are being combined.

U=A_0+A_1ln( √x ^{2}+y^{2} ) Find dU/dx
The derivative of U with respect to x is A1 x/(x²+y²).
In order to find the value of dU/dx, we need to differentiate U with respect to x.
As A0 and A1 are constants, they will remain the same after differentiation.
Therefore, dU/dx = d/dx (A1 ln (√x²+y²))
Here, we will use the chain rule.
So, the derivative of ln(√x²+y²) is (1/√x²+y²) d/dx (√x²+y²).
Applying chain rule, d/dx (√x²+y²) = (1/2) (x²+y²)^(-1/2) .
2x = x/(√x²+y²)
Therefore, dU/dx
= d/dx (A1 ln (√x²+y²))
= A1 (1/√x²+y²) d/dx (√x²+y²)
= A1 (1/√x²+y²) . (x/(√x²+y²))

theorem: for any real numbers, x and y, max(x,y)=(1/2)(x + y |x-y|). one of the cases in the proof of the theorem uses the assumptions that |x-y|=x-y. select the case that corresponds to this argument.
a. x ≥ y
b. x < y
c. x < 0
d. x ≥ 0
The case that corresponds to the assumption |x-y|=x-y is option (a) x ≥ y. The assumption |x-y|=x-y corresponds to the case x ≥ y in the proof of the theorem.
The assumption |x-y|=x-y is valid when x is greater than or equal to y. In this case, the difference between x and y, represented as (x - y), is non-negative. Since the absolute value |x-y| represents the magnitude of this difference, it can be simplified to (x - y) without changing its value.
This assumption is important in the proof of the theorem because it allows for the direct substitution of (x - y) in place of |x-y|, simplifying the expression. It helps establish the equality between the maximum function max(x, y) and the expression (1/2)(x + y + |x-y|).
By selecting the case x ≥ y, where the assumption holds true, we can demonstrate the validity of the theorem and show how the expression simplifies to the expected result.
