What is the value of v?

The unknown number deduced by solving the equation 4x - 1 = 6x +9 is -5.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

Let the unknown number be x.

First multiply the number by 4 = 4x

Then subtract 1 from it = 4x -1

This results in the same number as when the number is multiplied by 6 and 9 is added to it = 6x + 9.

So the equation will be -

4x - 1 = 6x +9

4x - 6x = 9 + 1

-2x = 10

-x = 10/2

x = -5

Therefore, the number obtained is -5.

Answer:

Step-by-step explanation:

fter solving the algebraic equation, Miguel has 4 quarters, 12 dimes and 16 nickels.

What is algebra?

One of the earliest areas of mathematics that deals with number theory, geometry, and analysis is algebra. Algebra is also defined as the study of mathematical rules and symbols through the manipulation of those mathematical symbols.

The number of quarters is taken to be x, then the number of dimes will be 3x, and the number of nickels will be 3x + x = 4x

$3.00 when converted to cents is 300 cents.

The value of nickels is 5 x 4x=20x.

The value of dimes is 10 x 3x=30x.

The value of quarters is 25x.

As the total value of money Miguel has is 300 cents, then the algebraic equation will be -

20x + 30x + 25x = 300

Solve to get the value of x -

75x = 300

x = 4

Therefore, the amount of quarters is x = 4 quarters.

The amount of dimes is x = 3x = 3 x 4 = 12 dimes.

The amount of nickels is 4x = 4 x 4 = 16 nickels.

Answer:

10cm

Step-by-step explanation:

Answer:

x ≈ 16.4 cm

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan26° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{8}{x}[/tex] ( multiply both sides by x )

x × tan26° = 8 ( divide both sides by tan26° )

x = [tex]\frac{8}{tan26}[/tex] ≈ 16.4 cm ( to 1 dec. place )

A problem is just a function or even a mapping of inputs to outputs. An algorithm is a recipe for solving a problem with concrete and unambiguous steps.

In mathematics and computer science, an algorithm is a finite sequence of rigorous instructions used to solve a class of specific problems or perform a computation.

Algorithms are data calculation and processing specifications. More advanced algorithms can use conditionals to divert code execution through various paths (referred to as automated decision-making) & deduce valid inferences (referred to as automated reasoning), eventually achieving automation.

Alan Turing used metaphorical terms like "memory", "search," and "stimulus" to describe machines.

The two characteristics of a star to become a black hole are:

The correct options are C and D.

When a star has consumed all its fuel (like hydrogen), that is to say, when it is at the end of its life, it can become a black hole. For this to happen, the mass of the star must be greater than 20 times the mass of the Sun. If a star is at the end of its life cycle but has a mass that is less than 20 times the Sun's mass, it will not become a black hole.    

The given options:

A. Its mass is equal to that of the sun. False

Its mass must be greater than 20 times the mass of the Sun.

B. It has an abundant supply of hydrogen. False

When it has an abundant supply of hydrogen, the star is at the beginning or the middle of its life cycle, and to become into a black hole it must be at the end of it.  

C. Its mass is greater than 20 times the mass of the Sun. True

Yes, its mass must be greater than 20 times the mass of the Sun.        

D. It is dying. True

The star must have no more fuel to continue its life cycle.

The confidence interval is (22.68,29.52).

In statistics, a confidence interval describes the likelihood that a population parameter would fall between a set of values for a given percentage of the time. Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts. Therefore, it can be concluded that there is a 95% probability that the true value falls within that range if a point estimate of 10.00 is produced using a statistical model with a 95% confidence interval of 9.50 - 10.50.

n = 10

x = 26.1

s = 4.2

Two-sided confidence interval :

CI = [tex](x-\frac{z*s}{\sqrt{n}},x+\frac{z*s}{\sqrt{n} } )[/tex]

    = [tex](26.1-\frac{2.576*4.2}{\sqrt{10}},26.1+\frac{2.576*4.2}{\sqrt{10}} )[/tex]

    = (26.1−3.42,26.1+3.42)

    = (22.68,29.52)

Hence, the confidence interval is (22.68,29.52).
