Answer:
D: a single firm supplies all the output.
Step-by-step explanation:
A natural monopoly runs most efficiently when one large firm supplies all of the output.
A natural monopoly occurs when the most efficient number of firms in the industry is one. As the name suggests, monopoly means single. We can also say that it is a market structure characterized by a single seller, selling a unique product in the market.
A natural monopoly functions by having a single firm supply all output in a specific market, typically due to economies of scale. This usually occurs in markets where having multiple firms would be inefficient and costly, such as utilities. Government usually regulates these to protect consumers.
Explanation:A natural monopoly functions in a manner where a single firm supplies all the output in a particular market. This is typically because this single firm can produce the total output in the market at a lower cost compared to several firms due to economies of scale. For example, in the utilities industry (like water or electricity), it would be highly inefficient and costly to have multiple firms deliver these services. Therefore, a single firm, or a 'natural monopoly', can provide these services at a lower cost.
The government often regulates natural monopolies to prevent abuse of monopoly power. This is done to ensure fair prices and adequate supply to consumers.

Finding the perimeter of each rectangle 96ft width 124ft length
Answer:
440 ft
Step-by-step explanation:
Perimeter(p) of a rectangle is 2l + 2w
Where 'l' is the length and 'w' is the width.
p = 2(96ft) + 2(124ft) = 192 ft + 248 ft = 440 ft
Can anyone help me with these two plz
Answer:
Part 1) The scale factor is [tex]1.5[/tex]
Part 2) The altitude QS is [tex]4\ units[/tex]
Part 3) The scale factor is [tex]\frac{2}{3}[/tex]
Part 4) The value of x is [tex]12\ units[/tex]
Part 5) The perimeter of ABCDE is [tex]46\ units[/tex]
Step-by-step explanation:
Part 1) Find the scale factor of triangle TQR to triangle NQP
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z-----> the scale factor
[tex]z=\frac{NP}{RT}[/tex]
substitute the values
[tex]z=\frac{24}{16}=1.5[/tex]
Part 2) Find the length of the altitude QS
we know that
To find the altitude QS, divide the altitude of triangle NQP by the scale factor
so
[tex]QS=\frac{6}{1.5}=4\ units[/tex]
Part 3) Find the scale factor of FGHJK to ABCDE
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z-----> the scale factor
[tex]z=\frac{AB}{FG}[/tex]
substitute the values
[tex]z=\frac{10}{15}=\frac{2}{3}[/tex]
Part 4) Find the value of x
we know that
The value of x is equal to multiply the length side FK by the scale factor
so
[tex]AE=FK(z)[/tex]
substitute the values
[tex]AE=18(2/3)=12\ units[/tex]
Part 5) Find the perimeter of ABCDE
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
Let
z-----> the scale factor
x-----> the perimeter of ABCDE
y-----> the perimeter of FGHJK
[tex]z=\frac{x}{y}[/tex]
we have
[tex]z=\frac{2}{3}[/tex]
[tex]y=15+9+12+15+18=69\ units[/tex]
substitute the values
[tex]z=\frac{x}{y}[/tex]
[tex]x=(z)(y)=\frac{2}{3}(69)=46\ units[/tex]
The variables x and y vary inversely If x=5 when y=12, then find the value of x when y=32
Answer:
x=15/8
Step-by-step explanation:
Inverse variation is given by
xy = k
Substituting x=5 and y=12
5*12 = k
60 =k
Our original equation is xy = 60
Now let y=32
x*32 = 60
Divide each side by 32
32x/32 = 60/32
Divide top and bottom by 4
x = 15/8
What is the product of 2/8 and 3/5?
Multiply the top values together and the bottom values together.
(2/8)*(3/5)
=(2*3)/(8*5)
=6/40
=3/20
Hope this helps!
Answer:
3/20
Step-by-step explanation:
2 3
-- * --- = 6/40, or 3/20
8 5
You may find it easier to multiply if you write the multiplicands as shown above, instead of 2/8 and 3/5. Then: 2 times 3 is 6, and 8 times 5 is 40.
Reduce 6/40 to 3/20, your final answer.

Answer: (3, 10)
Step-by-step explanation:
X=3 y=10
Answer:
x = 3
y = 10
Step-by-step explanation:
Equation (1) : -2x + y = 4
Equation (2) : y = 3x + 1
Substitute (2) into (1):
-2x + (3x + 1) = 4
-2x + 3x + 1 = 4
x + 1 = 4
x = 3
Sub x = 3 into (2):
y = 3(3) + 1

We apply distributive property to the terms of parentheses:
[tex]2x-5 = 5x-2[/tex]
We subtract 5x on both sides of the equation:
[tex]2x-5x-5 = -2\\-3x-5 = -2[/tex]
Suamos 5 on both sides of the equation:
[tex]-3x = -2 + 5\\-3x = 3\\x = - \frac {3} {3}\\x = -1[/tex]

The prism below is made of cubes which measure 1/3 of an inch on one side. What is the volume?
a. 10/9 cubic in
b. 10 cubic in.
c. 30 cubic in.
d. 10/3 cubic in
Answer:
the answer is A. 10/8 cubic in.
Step-by-step explanation:
V = LWH
length is 2 (1/3 in)
width is 3 (1/3 in)
height is 5 (1/3 in)
V = 2/3 in * 3/3 in * 5/3 in.
V = 10/9 cubic in.
The volume of the prism is 10 cubic inches, making the correct answer option b.
To find the volume of the prism made up of cubes each measuring 1/3 of an inch on one side, we first need to understand the volume of one cube.
The volume of a cube is calculated using the formula:
Volume = side³Given that each side of the small cube is 1/3 inch, we calculate:
(1/3 inch)³ = 1/27 cubic inchesNext, we need to determine the total number of these small cubes that make up the prism. Let's assume the prism consists of 270 of these small cubes.
The total volume of the prism is calculated by multiplying the volume of one small cube by the total number of cubes:
Volume of prism = 270 × 1/27 cubic inches = 10 cubic inchesThus, the correct answer is:
Option b. 10 cubic in.Pam has monthly mortgage payment of $750. Her annual property taxes are $1200,her PMI is $55/month, and her homeowners insurance is $800 per year. How much is deposited into Pam’s escrow account each month?
Answer:
$100 + $66.67 + $55 = $221.67/month, which is the amount that must be deposited into Pam's escrow account each month....
Step-by-step explanation:
Pam's annual taxes are $1200 per year. It means her escrow each month needs to have 1/12 of that amount. 1200/12 = $100 per month
Her homeowner's insurance is $800 per year, that's 1/12 of that needs to be in her escrow account each month:
$800 / 12, or $66.67/month.
And PMI is $55/month
Add these three together:
$100 + $66.67 + $55 = $221.67/month, which is the amount that must be deposited into Pam's escrow account each month....

If 62% of the people at a certain conference are doctors, 48% are women, and 36% are female doctors, what is the probability that a person selected at random at this conference is a doctor or woman (or both)?
62 plus 48 is 110
Then add everyone together to find the total 62+48+36 which is 152
110 over 152 is the probability that a person selected at random will be a doctor or woman
Hope this helps;)
The probability that a person at random from the conference is either a doctor or a woman (or both) is 74%, computed from the principle of inclusion and exclusion.
Explanation:The probability of a person at the conference being a Doctor or a Woman (or both) can be found by adding the individual probabilities - that of being a woman and that of being a doctor - and subtracting the probability of being both a doctor and a woman because this is counted twice in the addition. This is called the principle of inclusion and exclusion in probability theory. So by substituting the given percentages, P(Doctor or Woman) = P(Doctor) + P(Woman) - P(Doctor and Woman) = 62% + 48% - 36% = 74%. So, the probability that a person chosen at random from the conference is either a doctor or a woman (or both) is 74%.

What can you say about the yvalues of the two functions f(x)=3^x-3 and g(x)=7x^2-3 please answer
Answer:
Step-by-step explanation:
This question is too general. We can take a look at the behaviors of the two different graphs:
f(x)=3^x-3 is an exponential function whose y-intercept is (0, -2). Note that 3^0 = 1. To draw this function, we'd drawn f(x)=3^x first and then translate the whole graph down by 3 units. The graph appears in Quadrants III, IV and I, in that order.
g(x)=7x^2-3 is not an exponential function, but rather a quadratic whose graph is a parabola. Here the parabolic graph opens up. Its y-intercept is (0, -3). This graph will intersect that of f(x)=3^x-3 in two places.
A: False. It is g that has minimum y value of -3. The minimum y value of f is -2.
B: The smallest y value f can have is just above y = -2. y = -2 is the horizontal asymptote for this function. The smallest y value g can have is -3. So B is False.
C: True. g has the smallest possible y-value; it is -3.
D: True. The min. y-value of g is -3.

At a local company, the ages of all new employees hired during the last 10 years are normally distributed. The mean age is 34 years old, with a standard deviation of 10 years. Find the percent of new employees that are no more than 40 years old. Round to the nearest percent.
Answer:
P = 73%
Step-by-step explanation:
We look for the percentage of employees who are not more than 40 years old.
This is:
[tex]P = \frac{x}{n} *100\%[/tex]
Where x is the number of new employees who are not over 40 years old and n is the total number of new employees.
We do not know the value of x or n. However, the probability of randomly selecting an employee that is not more than 40 years old is equal to [tex]P = \frac{x}{n}[/tex]
Then we can solve this problem by looking for the probability that a new employee selected at random is not more than 40 years old.
This is:
[tex]P(X< 40)[/tex]
Then we find the z-score
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
We know that:
μ = 34 years
[tex]\sigma = 10[/tex] years
So
[tex]Z = 0.6[/tex]
Then
[tex]P (X<40) = P (\frac{X- \mu}{\sigma} < \frac{40-34}{10})\\\\P(X<40) = P(Z<0.6)[/tex]
So we have
[tex]P(Z<0.6)[/tex]
Looking in the normal standard tables:
[tex]P(Z<0.6)=0.726[/tex]
Finally P = 73%

Step-by-step explanation:
You can use what is called geometric mean to solve this.
The hypotenuse of this triangle is split into two sections. One section corresponds to/equal to the altitude which is our "X", which corresponds to/equal to the second section.
You find "X" by using geometric mean and the proportion:
16/X=X/9
Then cross multiply to get 16 x 9= 144
then 144=x²
Solve for X.
X=12
