Based on the supply graph and demand graph shown above, the price at the point of equilibrium is $ 30.

Demand refers to quantity of a commodity that the consumers are willing to, able to purchase at a given price during a given period of time. Supply refers to quantity of a commodity that the producers are willing to, able to offer for sale at a given price during a given period of time.

Demand curve slopes downward due to inverse relationship between price and quantity demanded whereas supply curve slopes upward due to direct relationship between quantity supplied and price. When both demand and supply curve intersect with each other balance is achieved. Intersection point between demand and supply curve is known as equilibrium.

At this point when prices are equal is known as equilibrium price and when quantiy demanded or supplied are equal it is known as equilibrium quantity. When we combine the given graph. Equilibrium is achieved at a point when price is equal to $ 30 and quantity is equal to 20 units.

Use elimination.

Add the equations by columns to get the third equation,

\(2x+5x=7x\)

\(3y-3y=0\)

\(13+1=14\)

The new equation has only one unknown, \(7x+0=14\) so \(x=2\).

Now plug in the fact that \(x=2\) into one of the equations and solve for y (I will pick 2nd equation),

\(5\cdot2-3y=1\)

\(-3y=-9\implies y=3\).

The value of \(x=2\) and \(y=3\).

The equation of a line in the slope intercept form is expressed as

y = mx + c

where

m = slope

c = y intercept

The formula for calculating slope is expressed as

m = (y2 - y1)/(x2 - x1)

where

x1 and y1 are the x and y coordinates of the initial point

x2 and y2 are the x and y coordinates of the final point

From the information given, the initial point is (- 2, - 4) and final point is (2, 8)

Thus,

x1 = - 2, y1 = - 4

x2 = 2, y2 = 8

By substituting these values into the slope formula,

m = (8 - - 4)/(2 - - 2) = (8 + 4)/(2 + 2) = 12/4 = 3

We would find the y intercept, c by substituting m = 3, x = - 2 and y = - 4 into the slope intercept equation. We have

- 4 = 3 * - 2 + c

- 4 = - 6 + c

Adding 6 to both sides of the equation,

- 4 + 6 = - 6 + 6 + c

c = 2

By substituting m = 3 and c = 2 into the slope intercept equation, the equation of the line is

C) y = 3x + 2

Brian gets 5x and Colin gets x amount.

Brian gets 60 more than Colin, so you get:

5x - x = 60

Simplify to get:

4x = 60

Divide both sides by 4:

x = 15

Brian gets 5x = 5(15) = 75

Colin gets x = 15

75 + 15 = 90

The total amount they get is £90

Answer:

The answer is f^-1(x)=0^3\(\sqrt{x}\)+2

Step-by-step explanation: Now we just change y back to f(x) and add a 0−1 to write it in inverse notation We begin with f(x)= x 3−2 . To find the inverse of any equation, just switch x and y No, before we do that, I'm going to change the equation. I'm going to rename f(x) to y , just so that I don't have to deal with the parentheses or anything. Now, all I have to do is change what f (x) is called, not it's actual value. Anyways, we have y = x 3 − 2 Now we switch x and y and then solve for y Now we've got x = y 3−2 If we add 2 on both sides we have x + 2 = y 3 Now we just need to get y as simple as possible, which we'll do by cube rooting both sides of the equation. That leaves us with y=0 3√x+2 Now we just change y back to f(x) and add a 0−1 to write it in inverse notation

Answer: La probabilidad es 0.24

Step-by-step explanation:

De 240 personas, sabemos que 100 tienen una vista izquierdista.

Entonces la probabilidad de que una persona, seleccionada al azar, tenga una vista política izquierdista es:

Pa = 100/240 = 5/12

Entonces la probabilidad de que una persona elegida al azar NO tena una vista política izquierdista, es:

Pb = 1 - Pa = 1 - 5/12 = 7/12.

Queremos calcular la probabilidad que de 5 personas elegidas al azar, solo una tenga una vista izquierdista.

Entonces vamos a tener Pa una vez, y Pb 4 veces.

Y como sabemos, la probabilidad conjunta es igual al producto de las probabilidades, entonces:

p = Pa*Pb^4 = (5/12)*(7/12)^4

Pero esto va a ser para un solo arreglo (por ejemplo, de las 5 personas electas, la primera tiene una visión izquierdista), entonces tenemos que tener en cuenta las permutaciones, que van a ser las posibles permutaciones de un elemento en un espacio de 5 posibles espacios.

Son 5 permutaciones, y estas son:

La primera tiene visión izquierdista.

La segunda tiene visión izquierdista.

La tercera tiene visión izquierdista.

La cuarta tiene visión izquierdista.

La quinta tiene visión izquierdista.

Que también es igual a la combinatoria de 5 en 1.

\(C(5,1) = \frac{5!}{(5 - 1)!*1!} = 5\)

Entonces la probabilidad que buscamos va a ser:

P = 5*p = 5*(5/12)*(7/12)^4 = 0.24

Step-by-step explanation:

let's set the starting number as x

1. x times 2 = 2x

2. 2x- 138

3. result = 102

So, 2x-138 = 102

Now lets work backwards to solve for x.

1. 2x = 102

x = 51

So the starting number was 51.

What are numbers ?

A number is an arithmetic value that is used to calculate and represent a quantity. Numerical symbols, such as "3," are written to represent numbers. A number system is a logical way of writing numbers that uses digits or symbols to represent them.

An arithmetic value used to indicate amount is called a number. A number is a mathematical concept that is used for counting, measuring, and labeling. Thus, mathematics is built on numbers. For instance, this is a single butterfly, and these are four.

1. 5 × x = 45

   45 / 5 = x

    x = 9

45 ÷ 5 = 9

2. 200 + 600 = 800

300 + 400 = 700

3. 3 hours = 180 minutes

     3 * 60 minutes

24 hours = 1 day

24 months = 2 years

12 * 2 = 24

Let's solve this problem step-by-step:

      1. Let's put this in a fraction format:  

             6834 ÷ 17 = \(\frac{6834}{17}\)

      2. Now we know 6834 = 6800 + 34

            ⇒ so:

                   \(\frac{6834}{17} =\frac{6800+34}{17} =\frac{6800}{17} +\frac{34}{17}\)

     3. Now let's convert the fractions to denominators

100%/the total number = percent for one probability

100/5 = 20%

2 and 4 is even.

total even number * percent for one probability = total percent for even number

20% * 2 = 40%

therefore total even number is 40%

The probability is:

Step-by-step explanation:

Remember the formula for probability:

\(\boxed{\!\!\boxed{\bold{Probability=\frac{Favourable~outcome}{total~outcomes}\quad}}\!\!}\)

In this case, the favourable outcome (an even number) is 2, because there are only 2 even numbers in the set.

As for the total outcomes, there are 5 of them, because we have 5 numbers total.

So the probability of choosing an even number is 2/5.

Answer:

The third measurement is 62°

Step-by-step explanation:

Hey there! Please take a look at the explanation for clear understanding to the answer and also let me know in comment if you have any doubts!

The theorem regarding it states that, sum of all 3 interior angles must equal to 180°.

That means, we will have this equation:

\(\displaystyle \large{28^{\circ} + 90^{\circ} + x=180^{\circ}}\) because we know two interior angles and one missing angle - sum of them equals to 180 degrees.

Then we solve for x-term to find the third measurement!

\(\displaystyle \large{118^{\circ}+x=180^{\circ}}\)

Subtract both sides by 118 degrees.

\(\displaystyle \large{118^{\circ}-118^{\circ}+x=180^{\circ}-118^{\circ}}\\\\\displaystyle \large{x=62^{\circ}}\)

Henceforth, the third measurement is 62°
