The firm is initially producing 250 units of output at point c, where the green line labeled "marginal cost" intersects with the red line labeled "average total cost."
This means that the marginal cost of producing 250 units of output is equal to the average total cost of producing 250 units of output.
Mathematically, the marginal cost of producing 250 units of output is equal to the change in total cost divided by the change in quantity, or MC = (TC₂ - TC₁)/(Q₂ - Q₁). In this example, the marginal cost of producing 250 units of output is equal to the average total cost, which is TC₂/Q₂. Therefore, the marginal cost of producing 250 units of output is equal to the average total cost at point c.

what is the probability mass function, p(x = x), for x? (round to two decimal places.)
The marginal probability mass function px(x) is:
Px(0) = 0.26
Px(1) = 0.48
Px(2) = 0.26
We have to determine the marginal probability mass function px(x).
We determine the total of each value of y(0, 1, 2) at x = 0 to evaluate the value of Px(0).
The values of y(0, 1, 2) at x = 0 is:
Px(0) = Py(0) + Py(1) + Py(2)
Px(0) = 0.10 + 0.11 + 0.05
Px(0) = 0.26
We determine the total of each value of y(0, 1, 2) at x = 1 to evaluate the value of Px(1).
The values of y(0, 1, 2) at x = 1 is:
Px(1) = Py(0) + Py(1) + Py(2)
Px(1) = 0.17 + 0.23 + 0.08
Px(1) = 0.48
We determine the total of each value of y(0, 1, 2) at x = 2 to evaluate the value of Px(2).
The values of y(0, 1, 2) at x = 2 is:
Px(2) = Py(0) + Py(1) + Py(2)
Px(2) = 0.06 + 0.14 + 0.06
Px(2) = 0.26

Assume the world population at the end of 2017 was 7.4 billion people. The population growth rate in 2018 is 1.07%. How many more people were on the planet at the end 2018?
At the end of 2018, the world population was approximately 7.53 billion people. This figure is calculated by taking the total population at the end of 2017, 7.4 billion people, and multiplying it by the population growth rate of 1.07%..
This means that the world population increased by approximately 130 million people in 2018. This population growth rate is consistent with the average growth rate of the world population over the last decade. While the population growth rate has been decreasing over the past few decades, it is still relatively high at 1.07%.
The high population growth rate is primarily due to high fertility rates in developing countries and a longer life expectancy in developed countries. This means that more people are born and fewer people die each year. As a result, the total population of the world increases each year.

The values in the table do not represent a proportional relationship. The y-values are not a constant multiple of the corresponding x-values.
Proportional Relationship AssessmentA proportional relationship exists between two variables when one variable is equal to a constant multiple of the other variable. In the given table, if x increases by 1 unit, the corresponding increase in y is not always the same.
For example, when x increases from 1 to 2, y increases by 2 units (from 3 to 5), but when x increases from 2 to 3, y increases by only 1 unit (from 5 to 6). This lack of a constant ratio between x and y means that the relationship between the two variables is not proportional.
The applicability of proportional relationships depends on the specific problem and the nature of the relationship between the variables being considered. In some cases, a proportional relationship may not be the best model to describe the relationship between variables, and alternative models may be more appropriate.

(1)a total of 28 ways the student can select 3 writing implements
2)A total of 25 ways the selection be made if no more than one ballpoint pen is selected.
For the first question, the student has three different types of writing implements and thus three different ways to make a selection. The student can choose any combination of three pencils, three ballpoint pens, or three felt-tip pens. This is known as a combination problem and can be solved using the combination formula. The combination formula, which is often written as "n choose k" (where n is the number of objects and k is the number of objects to be selected), can be used to calculate the total number of possible combinations.
In this case, the student has 4 pencils, 3 ballpoint pens, and 1 felt-tip pen, so the combination formula would be (4 choose 3) + (3 choose 3) + (1 choose 3). This simplifies to 28, meaning that there are 28 possible ways the student can select 3 writing implements.
For the second question, the student is limited to selecting no more than one ballpoint pen. Since the student can only select one ballpoint pen, the combination formula would now be (4 choose 3) + (2 choose 3) + (1 choose 3). This simplifies to 25, meaning that there are 25 possible ways the student can select 3 writing implements without selecting more than one ballpoint pen.

a. The speed of the truck in km/hr at the end of 20.0m is
v = (100 m/s) - (0.5 * 6.5 m/s^2 * 20.0 s^2)
v = (100 m/s) - (65 m/s)
v = 35 m/s
v = 35 * (3600 s/hr) / (1000 m/hr) = 126 km/hr
b. The time elapsed is
t = √(2 * 20 m / 6.5 m/s^2) = 3.19 s
The speed of the truck in km/h at the end of this distance is equal to 81.43 km/h.
The time elapsed is equal to 0.7939 seconds.
How to calculate the speed of the truck in km/h?In order to determine the speed of the truck in km/h at the end of this distance, we would apply the third equation of motion:
v² = u² + 2as
Where:
V represents the final velocity.U represents the initial velocity.S represents the distance travelled or covered.a represents the acceleration or deceleration.Next, we would convert the value of deceleration in m/s² to km/h² as follows;
Deceleration, a = 6.5 × 60⁴/1000 = -84,240 km/h².
Distance, s = 20/1000 = 0.02 m.
Substituting the given parameters into the third equation of motion, we have;
v² = 100² + 2(-84,240)(0.02)
Speed, v = √(10,000 - 3,369.6)
Speed, v = √6,630.4
Speed, v = 81.43 km/h.
Lastly, we would determine the time by using the first equation of motion:
V = U + at
Time, t = (V - U)/a
Time, t = (100 km/h - 81.43 km/h)/6.5
Time, t = [(100 × 1000/3600) - (81.43 × 1000/3600)]/6.5
Time, t = (27.78 - 22.62)/6.5

find the values of X such that the given vectors are orthogonal. xi + 2xj xi - 5j
The values of x that make the given vectors orthogonal are xi = 5 and xi = -2.
The dot product of two vectors is equal to zero when the vectors are orthogonal. Thus, to find the values of X such that the given vectors are orthogonal, we must set the dot product of the two vectors to zero and then solve the resulting equation. The dot product of two vectors is calculated by taking the sum of the product of the corresponding components of the two vectors. In this case, the dot product of the two vectors is calculated as:
(xi + 2xj) • (xi - 5j) = xi2 + 2xixj - 5xi - 10xj
Setting this equal to zero and solving for x, we obtain
xi2 + 2xixj - 5xi - 10xj = 0
Subtracting 2xixj from both sides, we get
xi2 - 5xi - 10xj = -2xixj
Factorizing the left-hand side, we get
(xi - 5)(xi + 2) = -2xixj
Setting the two factors on the left-hand side equal to zero and solving for x, we get
xi - 5 = 0 => xi = 5
and
xi + 2 = 0 => xi = -2
Thus, the values of x that make the given vectors orthogonal are xi = 5 and xi = -2.

What is a cuboid?A cuboid is defined as the type of quadrilateral that has 6 faces, 8 vertices, and 12 edges.
The volume of the cuboid;
volume of the cuboid;= l×w×h
= 3x4x4
= 48cm³
The volume of each cube = 1cm×1cm×1cm
The number of cubes available= 24 cubes
Therefore the remaining cubes = 48-24 = 24 cubes.

Data was collected on the weight, in ounces, of kittens for the first three months after birth. A line of fit was drawn through the scatter plot and had the equation w = 2.75 + 0.2d, where w is the weight of the kitten in ounces and d is the age of the kitten in days.
What is the w-intercept of the line of fit and its meaning in terms of the scenario?
0.2; a kitten who is just born is predicted to weigh 0.2 ounces
0.2; for each additional day after the kitten is born, its weight is predicted to increase by 0.2 ounces
2.75; a kitten who is just born is predicted to weigh 2.75 ounces
2.75; for each additional day after the kitten is born, its weight is predicted to increase by 2.75 ounces
Answer:
The w-intercept of the line of fit is 2.75, and it means that a kitten who is just born is predicted to weigh 2.75 ounces. This is because the equation of the line of fit is w = 2.75 + 0.2d, where w is the weight of the kitten in ounces and d is the age of the kitten in days. When d = 0, the equation becomes w = 2.75, so the w-intercept is 2.75.

Relative to ground level, a black garden ant digs -20 7/9 feet and a red harvester ant digs -20 39/50 feet.Which ant is closer to ground level?
The red harvester ant is closer to ground level.
What is Relative distance?The relative distance is defined as the product of the relative distance multiplied by the specified time. The relative distance unit is the same as the length unit.
Distance is typically defined as the amount of space between two locations that can be measured. In geography, a few different types of distance are used to explain not only the physical distance between two points but also the variations in distinct racial and ethnic groups, cultural traditions, political ideals, and social mores. A unique unit of measurement known as relative distance is used in geography to explain a variety of societal aspects.
As it has dug deeper (more negative) than the black garden ant. The number -20 39/50 is more negative than -20 7/9.
Therefore, The red harvester ant is closer to ground level.
