Estimate the value of 50.75 x 0.18

The equilibrium price is $12.

Equilibrium is the point where the quantity demanded is equal to the quantity supplied. The price at equilibrium is known as the equilibrium price and the quantity at equilibrium is known as the equilibrium quantity.

When shown on a graph, equilibrium is the point where the quantity demanded curve is equal to the quantity supplied curve.

When there is equilibrium, the equation of quantity demanded would be equal to the equation of quantity supplied.

-280 + 40p = 800  - 50p

In order to determine the value of p, take the following steps:

Combine similar terms: 800 + 280 = 40p + 50p

Add similar terms = 1080 = 90p

Divide both sides of the equation by 90 : 1080 / 90 = 12

Step-by-step explanation:

Based on the number of respondents with excellent health and those don't have health coverage, the probability that the respondent has excellent health or doesn't have health coverage is 33.61%

Out of 20,000 respondents, 2,524 people did not have health coverage. Out of those same 20,000 people, 4,198 respondents had excellent health coverage.

The probability that the respondent has excellent health or doesn't have health coverage is therefore:

= Probability that random person does not have health coverage + Probability that a respondent has excellent health coverage

= (2,524 + 4,198) / 20,000

= 33.61%

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Let us say puzzles solved by :

Arthur be x

Conan be y

Doyle be z

also,

Here, it is given that :

Arthur has completed four times as many jigsaw puzzles as Conan which means :

x = 4y.......(1)

Doyle has completed three times as many jigsaw puzzles as Conan which  means :

z = 3y.....(2)

Doyle has completed 12 fewer jigsaw puzzles than Arthur has means :

z = x-12....(3)

now, to find the number of jigsaw puzzles does Conan (y) we equate equation (2) and (3) to find the value of y also by putting value of x in equation (3) :

3y = x-12

3y = 4y-12

4y-3y = 12

y = 12

Therefore, Canon has 12 jigsaw puzzles in total.

In mathematical modelling, we take a real-world problem and write it as an equivalent mathematical problem.

We then solve the mathematical problem, and interpret its solution in terms of the real-world problem.

After this we see to what extent the solution is valid in the context of the real-world problem.

Mathematical modeling is one of the bases of mathematics education. Mathematical modeling is described as conversion activity of a real problem in a mathematical form. Modeling involves to formulate the real-life situations or to convert the problems in mathematical explanations to a real or believable situation.

It's extremely precise, since it's math-based, which allows you to develop accurate ideas and assumptions. It's concise, with clear and established rules. It gives you direction when trying to solve a problem.

By answering the above question, we may state that by equation A = S + 18 = 24 + 18 = 42 and Alex thus owns 42 books.

Using the equals notation (=) to indicate equivalence, a math equation links two statements. Algebraic equations prove the equality of three mathematical expressions by a mathematical assertion. The equal sign, for example, provides a gap between the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. You can use a mathematical formula to understand the connection between the two phrases that are inscribed on opposite sides of a letter. Most of the time, the symbol and the particular software match. e.g., 2x - 4 = 2 is an example.

Let's designate the quantity of books Alex has as "A" and the quantity of books his sister Scout owns as "S."

We learn the following from the issue:

A = S + 18 (Alex possesses 18 more books than his sister) (Alex owns 18 more books than his sister)

A + S = 66 (combined, they possess 66 books) (together, they own 66 books)

These two equations can be used to determine A:

The first equation is substituted into the second equation to yield:

(S + 18) + S = 66

2S + 18 = 66

2S = 48

S = 24

Scout has 24 books, thus we can apply the first equation to determine how many books Alex has:

A = S + 18 = 24 + 18 = 42

Alex thus owns 42 books.

Step-by-step explanation:

Factor the trinomial so that it will multiply nicely. 3 and 5 add up to 8 while they multiply to 15

The correct statement that is missing in the proof is m<5 + m<2 = 180 degrees

Supplementary angles are angles that sums up to 180 degrees. From the third proof, we can see that the measure of m<1 is equivalent to m<5.

Also from the 4th statement <1 and m<2 are supplementary meaning that the sum of <1 and <2 is equivalent to 180 degrees.

Since m<1 = m<5, we can replace m<1 as m<5 in the equation m<1 + m<2 = 180 from statement 4 to have m<5 + m<2 = 180 degrees by the substitution property.

Hence the correct statement that is missing in the proof is m<5 + m<2 = 180 degrees.

Step-by-step explanation:

A piecewise function that relates the salesperson total monthly income based off or his/her sales for the month is  X > 25000.

An accurate graph of this piecewise function is 2100.

The salesperson's monthly income if his/her sales were $43,000 for the month is $ 4250

Explanation for this is

a) S(x) = 0.02x + 2850  ( 0 < x < 25000 )

              0.05x + 2100  ( X > 25000 )

b) 25k  26k

    500  550

3400 = 0.05 ( 26000) + b

3400 = 1300 + b

b = 2100

c) 0.05 (43000) + 2100

= $4250

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x.

In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain.

The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

Given, we have the frequency table grades A,B,C,D,F with frequencies of 5,11,13,4, and 1 respectively.

According to the question the relative frequency, the specific frequency is divided by the total frequency.

The sum of all the frequencies is called relative frequency.

= 5 + 11 +13 +4 +1 = 34

The relative frequency of the
