To achieve the same level of pollution at a lower cost, the government could adjust the environmental standards for each plant based on their respective marginal social benefits of pollution.
The government's environmental standards require Plant A and Plant B to reduce their emissions by 60%. The marginal social benefit of pollution for Plant A is $500 and the marginal social benefit of pollution for Plant B is $125. This means that the benefit of reducing one unit of pollution for Plant A is $500, while for Plant B is $125.
This information suggests that Plant A has a higher marginal social benefit of pollution than Plant B. Since the government's standards require both plants to reduce emissions by the same percentage, Plant A will have to reduce a greater amount of pollution than Plant B to reach the same level of emissions. This means that the cost of reducing pollution for Plant A will be higher than the cost of reducing pollution for Plant B.
To achieve the same level of pollution at a lower cost, the government could adjust the environmental standards for each plant based on their respective marginal social benefits of pollution. For example, if Plant A has a marginal social benefit of $500 and Plant B has a marginal social benefit of $125, the government could require Plant A to reduce its emissions by 50% and Plant B to reduce its emissions by 70%. This would achieve the same level of pollution while minimizing the cost of reducing pollution for both plants.
Thus, To achieve the same level of pollution at a lower cost, the government could adjust the environmental standards for each plant based on their respective marginal social benefits of pollution.

Q3. There are 5 red sweets, 6 blue sweets and 9 yellow sweets in a bag.
Sarah takes a sweet at random.
She replaces it back and then
Take another sweet at random.
Work out the probability the both the sweets the same colour.
Answer:
Step-by-step explanation:There are a total of 20 sweets in the bag (5 red + 6 blue + 9 yellow).
To find the probability that Sarah takes two sweets of the same color, we need to find the probability of her choosing a sweet of a specific color on her first pick and then the probability of her choosing another sweet of that same color on her second pick.
For example, if she chooses a red sweet on her first pick, the probability of that happening is 5/20, or 1/4. Then the probability of her choosing another red sweet on her second pick, given that she already picked one, is 4/20, or 2/10. Therefore the probability of her choosing two red sweets in a row is (1/4) * (2/10) = 1/20.
Similarly, the probability of her choosing two blue sweets in a row is (6/20) * (5/20) = 3/50.
The probability of her choosing two yellow sweets in a row is (9/20) * (8/20) = 9/100.
The probability of her choosing two sweets of the same color is the sum of the probability of her choosing two red sweets, two blue sweets, or two yellow sweets in a row.
P(Two same color) = 1/20 + 3/50 + 9/100 = 11/50
So, the probability of her choosing two sweets of the same color is 11/50.
Solve for X, Leave in simplest radical form.
By the concepts of trigonometric ratios, the value of x in the right angle triangle is 1.

Why is 1 U and 1 V graph a straight line?
A 1-U, 1-V graph is a special type of graph that has only one vertex of degree 1 (U) and one vertex of degree 2 (V). The edge connecting the two vertices is called the "bridge" of the graph.
Because the graph has only one vertex of degree 2, it forms a simple path (a straight line) between the two vertices. The vertex of degree 1 is a leaf, which means it is only connected to one vertex, and the vertex of degree 2 is the other end of the path. The path is a simple one, meaning it has no loops or multiple edges between the two vertices.
In a 1-U, 1-V graph, the vertex of degree 1 (U) can be thought of as the start of the path and the vertex of degree 2 (V) as the end of the path. Because there are no other edges or vertices in the graph, the path is the only structure in the graph and it's a straight line.
It's important to note that a 1-U, 1-V graph is a special case of a graph and it's not a general representation of all possible graphs. Most graphs have more than one vertex and multiple edges, making them more complex than a simple straight line.

The value of upper quartile is, 300.
The value of 7th decile is, 250.2.
The value of 35th percentile is, 100.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The donations are as follows,
⇒ 50, 50, 50, 100, 100, 100, 150, 150, 200, 250, 250, 300, 300, 400, 500.
Now, We find the values as;
a) The upper quartile is,
⇒ Qₐ = a/4 (n + 1)

So, Q₃ is in 12th position.
So, The value of Q₃ = 300
The value of 7th decile is,
⇒ D₇ = 7/10 (15 + 1)
= 7/10 × 16
= 11.2
Here, 11.2 is between the position 11th and 12th position which are 250 and 300 respectively.

⇒ 300 - 250 = 50
Hence, The value of D₇ = 250 + 0.2
= 250.2
Now, The value of 35th percentile is,
⇒ Pₐ = a/100 (n + 1)
⇒ P₃₅ = 35/100 (15 + 1)
= 35/100 × 16
= 5.6
Here, 5.6 is between the 5th and 6th position which are 100 and 200 respectively.

6. 21 and 22 form a linear pair. If m/1 = (5x + 9) and m/2 = (3x + 11), find the measure of
each angle.
7. 21 and 22 are vertical angles. If mZ1 = (17x + 1) and m/2 = (20x-14), find m22.
8. ZK and ZL are complementary angles. If mZK = (3x + 3) and mL = (10x-4), find the
measure of each angle.
Answer:
Since 21 and 22 are vertical angles, they are congruent. Therefore, m/1 = m22.
Using the equation m/1 = (17x + 1) we can find the measure of the angle m22.
m22 = (17x + 1)
Since ZK and ZL are complementary angles, the sum of their measures is 90 degrees.
mZK + mL = 90
Using the equations mZK = (3x + 3) and mL = (10x-4) and substituting them in the equation, we can find the measure of each angle.
3x + 3 + 10x - 4 = 90
13x - 1 = 90
13x = 91
x = 7
Therefore, mZK = (3x + 3) = (3(7) + 3) = 24 and mL = (10x-4) = (10(7) - 4) = 66

To find the y-intercept, we can substitute x = 0 into the equation:
y = 2(0) - 6
y = -6
So the y-intercept of this equation is b = -6
b. y = 1/2 * x + 12
To find the slope of the equation, we need to find the coefficient of x which is 1/2. So the slope of this equation is m=1/2
To find the y-intercept, we can substitute x = 0 into the equation:
y = 1/2(0) + 12
y = 12
So the y-intercept of this equation is b = 12
Therefore, the slope-intercept form of the equation is y = 2x - 6 and y = 1/2x + 12 respectively.

To simplify the expression 3k + 9 - 2k + 11, we need to combine like terms and simplify the expression.
The first step is to combine the constants (numbers without variables)
3k + 9 - 2k + 11 = 3k - 2k + 9 + 11
The next step is to combine the variable k
3k - 2k = k
Now we have
k + 9 + 11 = k + 20
The final simplified expression is k+20
Answer:
20
Step-by-step explanation:
3k+(-2k) = 1k or just k
+9+11 = +20
= k+20

if weshipit offers a flat rate of $7.95 to ship a parcel up to ten pounds (as long as it fits within a 18 cm x 18 cm x 18 cm box), how many cubes can be shipped in this box for $7.95? be sure to check both the size and the weight constraints. ignore the weight of the box.
Cannot be answered because of incomplete data.
It is not possible to determine the number of cubes that can be shipped in this box for $7.95 without more information about the size and weight of the cubes. The weight constraint of ten pounds and the size constraint of 18 cm x 18 cm x 18 cm box only applies to the overall package and not to the individual cubes. The weight and volume of the individual cubes would need to be taken into account in order to determine how many could fit within the package while still adhering to the weight and size constraints.
The correct question should be:

A regular hexagon is inscribed in a circle of radius 2 units. In square units, what is the area of the hexagon
The area of inscribed regular hexagon is 6[tex]\sqrt{3\\[/tex] unit square using the properties of equilateral triangles which combined, form the hexagon.
In a circle, a regular hexagon can be inscribed with all the six vertices of hexagon touching the circumference of the circle. The center of the circle is the center of the hexagon itself.
Now, if we join the center with all the vertices of the hexagon, we see six equilateral triangles are formed. The other two sides of each triangle apart from the ones joining the vertices of hexagon, are radii of the circle and all the sides are equal in length. The attached image can be referred for better understanding.
To find the area of the hexagon, we need to find the area of single equilateral triangle and multiply it by 6, as six triangles make a regular hexagon.
Radius of the circle ([tex]r[/tex]) = 2 units
Area of a single equilateral triangle = [tex]\sqrt{3} /4[/tex] [tex]r^{2}[/tex]
=( [tex]\sqrt{3} /4[/tex] ) × [tex]2^{2}[/tex]
= [tex]\sqrt{3}[/tex]
Area of hexagon = Area of 6 equilateral triangles = 6 × [tex]\sqrt{3}[/tex]
Area of hexagon = [tex]6\sqrt{3}[/tex] [tex]units^{2}[/tex]

A memberhip to Gym A cot $200 to ign up and $10 per month. Gym B’ memberhip cot $0 to ign up and $60 a month. Write an equation to find out how many month you can belong to each gym for it to cot the ame at both place
So, the equation to determine the number of months is 200 + 10x = 0 + 60x.
Let x be the number of months you can belong to each gym for it to cost the same at both places.
The equation to determine the number of months is:
200 + 10x = 0 + 60x
To solve for x, we can subtract 200 from both sides of the equation:
10x = -200
And finally, we divide both sides by 10:
x = -20
Therefore, you can belong to each gym for -20 months for it to cost the same at both places. But since month are positive numbers, x=-20 is not a solution. Therefore, the statement is not true, the cost will never be the same for both gyms.

URGENT, pls answerr!!
Answer:
15/16
Step-by-step explanation:
In a dice, there are 3 even and 3 odd numbers.
So, to calculate the required probability, we will have to calculate the probability of getting an odd number in all of them.
Probability of getting odd number in 1 dice = 3/6 = 1/2
Probability of getting odd number in 4 dice =
1/2 x 1/2 x 1/2 x 1/2 = 1/16
Therefore, probability of getting atleast one even number is 1 - 1/16 = 15/16
15/16 is the answer.
