If has a decimal approximation of 3.4, then is between which two integers? In your final answer, include all calculations.

Answers

Answer: It is between 3 and 4.

Step-by-step explanation:

Integers are whole numbers and its opposite, for example,  -5,-4,-3,-2,-1, 0, 1,2,3,4, 5 ,....

Meaning that 3.4 is not an integer so it fall between two integers and those integers has to be positive because 3.4 is a positive number.  

3.4 is slightly greater than 3  but is less than 4.

Meaning that 3.4 is between the integers 3 and 4.

Step-by-step explanation:

-19-9=-28

-28/-4=7

thus x=7

3x + 5y + z = 2
x + 2y + 3z = 6
2x + 4y + 2z = 9

X = 2 - 5y - z / 3

X = 6 - 2y - 3z

What is the slope and equation of a line parallel to the x-axis passing through (3,7)?

Answers

Answer:

We know that the equation is y=7 because it passes through point (3,7), and 7 is the y-coordinate of that point (remember we don't really care about the 3 because since the line is parallel to the x-axis, it will pass through all values of x, so the 3 is irrevalent).

Step-by-step explanation:

The equation of the line passing through the point (3,7) and parallel to the x-axis is y =7.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

We know that the equation is y=7 because it passes through the point (3,7), and 7 is the y-coordinate of that point (remember we don't really care about the 3 because since the line is parallel to the x-axis, it will pass through all values of x, so the 3 is prevalent.

Answers

Responder:

0,9

Explicación paso a paso:

Sea P (MuT) la probabilidad de que una persona esté a favor de retransmitir partidos de fútbol o la existencia de canales de televisión de pago

probabilidad de que esté a favor de retransmitir partidos de fútbol sea P (M) = 0,8

Probabilidad de que esté a favor de la existencia de canales de televisión de pago P (T) = 0,4

La probabilidad de que esté a favor de la retransmisión de partidos de fútbol y también de la existencia de canales de pago sea P (MnT) = 0,3

Usando la fórmula de notación de conjuntos

P (MuT) = P (T) + P (M) - P (MnT)

Sustituir los parámetros dados

P (MuT) = 0,4 + 0,8-0,3

P (MuT) = 1,2-0,3

P (MuT) = 0,9

De ahí que la probabilidad de que una persona esté a favor de retransmitir partidos de fútbol o la existencia de canales de televisión de pago es de 0,9.

Michael invests USD 20 000 at 9.6% p.a. compounded monthly.
How long will it take for his investment to reach USD 25 000?

Given :

A = 25000

P = 20000

r % = 9.6 % = 0.096

n = 12

To Find :

The time taken say t.

Solution :

We know, compound interest is given by :

[tex]A=P(1+\dfrac{r}{n})^{n.t}[/tex]

Taking log both sides :

[tex]A=P(1+\dfrac{r}{n})^{n.t}\\\\log\ \dfrac{A}{P}= n.t\times log( 1+\dfrac{r}{n})\\\\t =\dfrac{1}{n}\times \dfrac{log\ \dfrac{A}{P}}{log(1+\dfrac{r}{n})}\\\\\\t=\dfrac{1}{12}\times \dfrac{log\ \dfrac{25000}{20000}}{log(1+\dfrac{0.096}{12})}\\\\\\t=2.33\ years[/tex]

how can you solve quadratic equation in one variable using factoring method?

Answers

Take a quadratic equation in standard form:
If there exists a sum of two numbers that equal b, whose addends produce a product that equals c, you can rewrite the quadratic as a product of two binomials.

For example, take .
When thought through thoroughly, -5 has addends -2 and -3 that produce 6 when multiplied.
Thus, we can rewrite the quadratic as.

I hope this helps! You can ask for clarifications if needed. :)

The steps are;

look for two numbers such that if added will give the coefficient of x and if multiplied will give the product of the constant and the coefficient of x²Factor the common value from both brackets and get the required variable

Let us assume the quadratic equation x² - 2x + 1 = 0

To solve this by factoring;

Step 1: We will first look for two numbers such that if added will give the coefficient of x and if multiplied will give the product of the constant andthe coefficient of x²

For the given equation, the two values are -1 and -1

The quadratic equation becomes;

x² - 1x - 1x + 1 = 0

x² - x - x + 1 = 0

(x²-x)-1(x-1) = 0

Step  2: Factorize the common value from both brackets

x(x-1)-1(x-1) = 0

x-1 = 0 and x - 1 = 0

x = 1twice

The given steps are the ways you can solve quadratic equations in one variable using factoring method
