Answer:   \(\frac{3}{4}\)c

Step-by-step explanation:

       If one pound of chicken costs c dollars, and we are writing an expression for 3/4 a pound of chicken, our expression will be the price (c) multiplied by how much chicken there is (3/4):

               3/4c

- In mathematics, an expression is a combination of numbers, variables (represented by letters), symbols, and operators, arranged in a way that represents some meaningful mathematical relationship or calculation.

- Expressions can be simple, like 3x or 4 + 5, or complex, like (3x + 4y) / (2x - 5y). Expressions are not equations or inequalities, as they do not contain an equal sign, but they can be used to build equations or inequalities.

The price of 1 pound of chicken is c dollars. To find the price of 3/4 pound of chicken, we can multiply the price of 1 pound by 3/4:

\(\begin{aligned}\sf Price\: of\: \dfrac{3}{4}\: pound\: of\: chicken& =\sf \dfrac{3}{4} \times c \\&=\boxed{\bold{\:\dfrac{3}{4}c\:}}\end{aligned}\)

Therefore, the expression for the price of 3/4 pound of chicken is 3/4c.

Answer:

yes, because the results are unlikely to occur by chance

Step-by-step explanation:

1/1000 is converted to 10% as a decimal. That's like saying for everyone 1000 people, at least one of the can be this "random chance". The smaller the general population is, the higher the affect this percentage has on that group. If the population is lower, than there might be more of a chance that it'll occur but also because there's a smaller population, there's less variety.

Answer:

a)\(R(x)=-520x^2+2600x\)

b)\(P(x)=-520x^2+2600x-30\)

c)x=2.5

d)P(x)=3220

Step-by-step explanation:

Let Demand function be  D=Ax+B

We are given that  When you charged $4 the demand was 520 log-ons per month

So, D = 520 , x = 4

So, 520=4A+B  ----1

We are also given that When you lowered the price to $3.50, the demand increased to 780 log-ons per month.

So, D=780 , x = 3.50

So, 780=3.5A+B ----2

Substract 2 form 1

4A+B-3.5A-B=520-780

0.5A=-260

\(A=\frac{-260}{0.5}\)

A=-520

Substitute value of A in 2

780=3.5(-520)+B

780-3.5(-520)=B

2600=B

So, D=-520x+2600

Revenue = Demand (x)=(-520x+2600)(x)

a) \(R(x)=-520x^2+2600x\)

b) Profit = Revenue - cost

\(P(x)=-520x^2+2600x-30\)

c)to obtain the largest possible monthly profit.

Equate the first derivative of profit to 0

P'(x)=-1040x+2600=0

\(x=\frac{2600}{1040}\)

x=2.5

d)Now to find  the largest possible monthly profit

Substitute x = 2.5 in Profit function

\(P(x)=-520(2.5)^2+2600(2.5)-30\)

P(x)=3220

7 raised to the power of 4 equals 2,401, and the exponent we were looking for is 4.

What is meant by power?

Power is a function that represents the number of times a base number is multiplied by itself. It is the rate at which work is done or energy is transferred, measured in watts.

What is meant by exponent?

An exponent is a mathematical notation used to indicate the number of times a quantity is multiplied by itself. It is written as a superscript and represents the power to which a number or expression is raised.

According to the given information

To find the value of the exponent that satisfies the equation 7ˣ = 2,401, we can take the logarithm of both sides of the equation with respect to base 7. This gives us:

log7(7ˣ) = log7(2,401)

x = log7(2,401)

Using a calculator, we can find that log7(2,401) is approximately 3. Therefore, the value of x that satisfies the equation 7ˣ = 2,401 is 3.

Alternatively, we could also use the fact that 2,401 is equal to 7⁴ - 2, which can be written as:

7⁴ - 2 = (7²)² - 2

= 49² - 2

= 2,401

Answer:

The inverse is 1/2x +3

Step-by-step explanation:

f(x) = 2x-6

Replace f(x) with y

y= 2x-6

Exchange x and y

x = 2y-6

Solve for y

Add 6 to each side

x+6 = 2y-6+6

x+6 = 2y

Divide each side by 2

(x+6)/2 = 2y/2

1/2 x+3 = y

The inverse is 1/2x +3

Answer:

Step-by-step explanation:

\(f(x) = 2x-6\)

To find the inverse of f(x) , equate f(x) to y that's

\(y = 2x - 6\)

Next interchange the terms that's x becomes y and y becomes x

\(x = 2y - 6\)

Next solve for y

Move 6 to the other side of the equation

That's

\(2y = x + 6\)

Divide both sides by 2 to make y stand alone

\( \frac{2y}{2} = \frac{x + 6}{2} \\ \\ y = \frac{x + 6}{2} \)

We have the final answer as

\( {f}^{ - 1} (x) = \frac{x + 6}{2} \\ \)

The inequality expression that corresponds to the solution of the inequality graph is x² + 3x - 3 < 0.

option B.

The inequality expression that corresponds to the solution of the inequality graph is determined by simplifying the equations as follows;

The solution of the graph,

x > -4 and x < 1

The first equation with "≥" is ruled out because the graph doesn't have a thick dot.

Let's simplify the second expression;

x² + 3x - 3 < 0

solve using quadratic formula;

x > -3.79 or x < 0.79

The third expression is ruled out since its solution will be complex.

For the last expression;

x² + 3x - 3 > 0

x < -3.79 or x > 0.79

Thus, the correct inequality expression is x² + 3x - 3 < 0.

Answer:

Inductive Reasoning is the process of arriving at a general conclusion based on observations of specific examples. When you try to find the pattern for a list of numbers or visuals, you are using inductive reasoning.

Answer:

An arithmetic sequence with a common difference of −2 is 20,18,16,14,12..

Step-by-step explanation:

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is same. Here, the common difference is -2, which means that each term in the sequence is obtained by subtracting 2 from the previous term.

To find the arithmetic sequence with a common difference of -2, you can start with an first term and then subtract 2 successively to find the subsequent terms.

Let the initial term is 20. Subtracting 2 from 20, we get 18. Subtracting 2 from 18, we get 16. Continuing this pattern, we subtract 2 from each subsequent term to generate the sequence. The arithmetic sequence with a common difference of -2 starting from 20 is

20,18,16,14,12

In this sequence, each term is obtained by subtracting 2 from the previous term, resulting in a common difference of -2.

Answer:

I would say A because 5000/70 is roughly like 80 something so it's less than 100 either way, so 100 is the best guess

Step-by-step explanation:

we would expect m to be positive.

In this case, we're considering a formula of the form y = mx + b, where y represents the cost of a four-year college x years after 2010. The variable m represents the coefficient of x, which determines the slope of the line.

Since we're discussing the cost of college, it's reasonable to expect that it generally increases over time. Therefore, we would expect the coefficient m to be positive. A positive value of m indicates that as the number of years after 2010 increases (x), the cost of college (y) will also increase.

If m were negative, it would imply a decreasing cost over time, which is less likely for a four-year college. If m were zero, it would indicate that the cost remains constant regardless of the number of years after 2010, which is also unlikely given the rising trend in college costs.

The radionkulider theorem describes the relationship between radicals and kulids. Thus explaining that when one adds a radical to the square root of a kulid, one would get a radia kulifer and those being divided together would make an ultimate of a radionklider. Another way this is applied is if one subtracts the radion and the kulid from each other, this would merge into the property of radionkulider and would ultimateley give you a radionklider formula and theorem.

Step-by-step explanation:

The radionuklider thereom is a simple 4 step process to figure out the force of Shrek's Fart.

The equation of the first step is:

sf = d+f+sp/ts

shrek's farts = diarrihha mass + fart pressure + overall smell degree / toilet size

The probability is closer to one than zero.

Probability theory is used to analyze and predict the likelihood of events happening in various fields such as statistics, gambling, physics, finance, and more. It allows us to make informed decisions based on the likelihood of different outcomes. In probability theory, the total number of possible outcomes is important to determine the probability of a single event occurring. By comparing the favorable outcomes to the total outcomes, we can calculate the probability of an event happening.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event. Probability for Class 10 is an important topic for the students which explains all the basic concepts of this topic. The probability of all the events in a sample space adds up to 1.For example, when we toss a coin, either we get Head OR Tail, only two possible outcomes are possible (H, T). But when two coins are tossed then there will be four possible outcomes,  i.e {(H, H), (H, T), (T, H), (T, T)}.

The equation of the line with the given points is y = 6x - 4. This can be derived by calculating the slope of the line, which is 6, and then using the point-slope form of the equation of a line, y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. In this case, the given points are (x1, y1) = (1, 10), so the equation of the line is y - 10 = 6(x - 1) or y = 6x - 4.

Write the equation of the line in slope-intercept fo

Step-by-step explanation:

the general slope-intercept form is

y = ax + b

a is the slope, which is the ratio of "y coordinate change / x coordinate change" when going from one point to another on the line.

b is the y-intercept - the y value when x = 0.

for the slope we see

x changes by +2 (from 1 to 3)

y changes by +6 (from 10 to 16)

so, the slope a is +6/+2 = 3

and the semi-ready equation is

y = 3x + b.

now we use one of the points in the equation to solve for b. I picked (1, 10) :

10 = 3×1 + b = 3 + b

b = 7
