Answer:

  (4)  750 < p < 1500

Step-by-step explanation:

The total cost for p people is ...

  c = 750 +2.25p

The average cost per person is this total divided by the number of people:

  c/p = (750 +2.25p)/p

  c/p = (750/p) +2.25

Natasha wants this to be between 2.75 and 3.25:

  2.75 < c/2 < 3.25

  2.75 < 750/p +2.25 < 3.25 . . . . . . use the expression for c/p

  0.50 < 750/p < 1.00 . . . . . . . . . . . subtract 2.25

We can split this to two inequalities to find the limits of p.

Left one

  0.50 < 750/p

  0.50p < 750 . . .multiply by p

  p < 1500 . . . . . . multiply by 2

Right one

  750/p < 1

  750 < p . . . . . . multiply by p

These bounds on p can be summarized as ...

  750 < p < 1500 . . . . matches choice (4)

Additional comment

Once you realize that the fixed costs will be divided by the number of people attending, the maximum cost you want ($1 more than the per-person charge) will set the minimum number of people. To have the $750 fixed cost contribute only $1 to the cost per person, there must be at least 750 people to share that cost. The only answer choice with a 750 person minimum is (4).

Step-by-step explanation:

A free semigroup is a collection of all possible finite sequences of symbols generated by a set of symbols, where the multiplication operation is concatenation of such sequences.

A free semigroup is a semigroup that is generated by a set of symbols, where the multiplication operation is defined as concatenation of finite sequences of symbols. In other words, a free semigroup is a collection of all possible finite sequences of symbols, where the multiplication operation is concatenation of such sequences.

The "free" in "free semigroup" comes from the idea that there are no restrictions on how the elements of the semigroup are combined, as long as they are concatenated in a finite sequence. There are no additional relations or rules imposed on the multiplication operation, which makes it "free" in the sense that the operation is determined solely by the set of symbols being used.

For example, consider the set of symbols {a, b}. The free semigroup generated by this set would consist of all possible finite sequences of the symbols a and b, including the empty sequence (). The multiplication operation would be defined as concatenation of sequences, such that (a, b)(b, a, b) = (a, b, b, a, b). Note that there are no additional rules or relations imposed on the multiplication operation.

Step-by-step explanation:

it has a repeating domain so it can not be a function

0,−1,2,1,0 has two values corresponding to a range of functions so it will not form a function so option (C) will be correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

For example f(x) = x²

Now if we put x = 1 then it is called as domain variable while the value of functin at x = 1 its that f(1) = 1 called range variable.

To be a relation a function for every single unique input there must be single unique output.

Since the interval 0,−1,2,1,0 has 2 inputs for single output so it will not form an function.

Hence "0,−1,2,1,0 has two values corresponding to a range of functions so it will not form a function".

The exact acreage of wheat expansion during the first 5 years of the 1940s would require access to historical data .Land prices increased significantly due to the high demand for wheat and the increased production.

The Great Plains region includes parts of the United States and Canada, specifically the central and western portions of North America. In the United States, it includes parts of Montana, North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Texas, Colorado, Wyoming, and New Mexico. In Canada, it includes parts of Alberta, Saskatchewan, and Manitoba.

During the 1940s, the Great Plains region of the United States, which includes states such as Kansas, Nebraska, Oklahoma, and parts of other surrounding states, experienced a significant expansion in wheat production. This period is often referred to as the "wheat boom" era.

During the early 1940s, there was a high demand for wheat due to World War II, as wheat was a staple crop used to feed soldiers and provide food aid to war-torn regions. This resulted in increased wheat production in the Great Plains region. However, the exact acreage of wheat expansion during the first 5 years of the 1940s would require access to historical data .

As for the prices of land being sold during that time, it is also difficult to provide precise information without specific data. Land prices can vary depending on various factors such as location, quality of land, demand, and economic conditions. However, it is generally known that during the wheat boom era of the 1940s, land prices in the Great Plains region increased significantly due to the high demand for wheat and the increased production. The exact percentage of increase would require access to historical data and research.

As a result, the company produced number of rods are **56** rods.

What exactly is radius?

A radius is a section of a straight line in geometry that connects a circle's or sphere's center to its edge or surface Its length is divided by the circle's diameter by two.

Each rod has a diameter of 6 centimeters, hence the radius is 3 centimeters. Each rod has a 20-centimeter height.

The following formula can be used to determine a cylinder's volume:

V = πr²h

where V stands for volume, r for radius, which is equal to half of the diameter, and h for height.

Adding these values to the formula yields the following results:

V = π(3)²(20) (20)

V = 180π

The volume of each rod is therefore 180 cubic centimeters.

30520.8 cubic centimeters of steel were used to make how many rods?

To find out,

divide the total volume of steel by the volume of each rod:

30520.8 / (180π) ≈ **56** rods

Answer:

B. Socialism

Step-by-step explanation:

In contrast to capitalism, socialists believe the shared ownership of resources and central planning offer a more equitable distribution of goods and services.

Karl Marx was the most prominent voice of socialism and believed the working class would rise up against the wealthy when faced with injustices.

I'm naming the left shape shape A and the right one shape B to make things easier to understand:

If these are the same shapes we can assume that Shape A was reduced by a factor of 2.5 to form Shape B (10/4=2.5).

With this number we can solve for x by multiplying 5 by 2.5 since we are enlarging Shape B to create Shape A. 5*2.5 is 12.5 so x=12.5.

For the two other missing sides I did the same step except dividing instead because we are going from big to small.

Top side: 8/2.5= 3.2

Right side: 10/2.5= 4

Step-by-step explanation:

it seems you solved the tricky part yourself already.

just to be sure, let's do the first derivative here again.

the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...

f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =

= 3t⁴ + 18t³ + 24t² + 18t + 21

f'(t) = 12t³ + 54t² + 48t + 18

and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).

we simply put the input number (2) at every place of the input variable (t).

so,

f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

All of the coordinates of the points of Triangle 2 are 2/6 = 1/3 of those of Triangle 1. The scale factor is 1/3.

The solution to the equation is x = 2 7/18

From the question, we have the following parameters that can be used in our computation:

3x + 2/3 =7 5/6

Solve the equation by first subtracting 2/3 from each side

So, we have

3x = 7 1/6

Divide both sides of the equation by 3

P (no snowfall) = 0.770

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

We have to given that;

Based on a weather record, the probability of snowfall in a certain town in New York on January 1 is 0.230.

Now, WE get;

the probability that next year there will be no snowfall in that town on January 1 is,

P (no snowfall) = 1 - P (snowfall)

P (no snowfall) = 1 - 0.230

P (no snowfall) = 0.770
