The ordered pair for the given solution set should be (-1, 6) when the graph solution set for the given inequality function is involved.

What is inequality function?

Since an inequality is merely a particular kind of relation, we can graph it just like we would any other relation. When dealing with inequalities, the trick is to shade large portions of the graph rather than using lines to connect the dots. But you could use some cover.

The given inequality function be like

y > 1 ÷ 3x + 4

The ordered pair refer to the solution set that provided by plotting the graph of the inequality, that expressed the inequality where an equation, plotting the graph along with a solid line, and shading the sides should be above the line of the graph to show the greater than or equal to sign.

Hence, the ordered pair for the given solution set should be (-1,6).

Given that the first two sides of a triangle are 8 cm and 10 cm in length, the third side's range of potential lengths will be [2,18].

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself. The difference between the highest and lowest values for a given data collection is the range in statistics. For instance, the range will be 10 - 2 = 8 if the given data set is 2, 5, 8, 10, and 3. As a result, the range can also be thought of as the distance between the highest and lowest observation.

Here,

The minimum length can be,

=10-8

=2 cm

The maximum length can be,

=10+8

=18 cm

(10-8)<x<(10+8)

2<x<18

The range of possible lengths for the third side will be [2,18] as The lengths of two sides of a triangle are 8 cm and 10 cm.

Steps for Solving Linear Equation

(10×12)+(5×11)+(12×12)=Y

Multiply 10 and 12 to get 120. Multiply 5 and 11 to get 55. Multiply 12 and 12 to get 144.

120+55+144=Y

Add 120 and 55 to get 175.

The total number different groups of four subjects are possible are 4845 ways.

The formula for the combination is-

ⁿCr = n!/r!(n - r)!

We are wondering in how many distinct options there are to choose 4 subjects out of 20;

n = 20

r = 4.

Sequence is not important because the topics can be arranged in any order and still form the same group, hence we must use a combination:

Review the combination's definition:

²⁰C₄ = 20!/4!(20 - 4)!

²⁰C₄ = 20!/4!16!

Answer:

x = 20

Step-by-step explanation:

the 3 unknown angles form a right angle and sum to 90° , that is

x + 2x + x + 10 = 90

4x + 10 = 90 ( subtract 10 from both sides )

4x = 80 ( divide both sides by 4 )

x = 20

Answer:

Step-by-step explanation:

From the picture we know that x + 2x + x + 10 = 90°

x + 2x + x + 10 = 90

4x = 80

x = 80 : 4

x = 20°

EV = - + prob(win)*win

= -5 + 1/1000 * 375

=  -4.62

The requried, the expected value for a person that buys one ticket is approximately -$4.62. The correct answer is option A. -$4.62.

To calculate the expected value, we need to consider the probability of winning the color television and the corresponding value of the prize. We can then subtract the cost of buying the ticket to find the expected value.

Given:

Cost of one ticket = $5

Value of the color television (prize) = $375

Number of tickets sold = 1000

The probability of winning the color television is 1 out of 1000, as only one ticket will be selected out of the total 1000 tickets sold.

Expected Value (EV) = (Probability of winning * Value of prize) - Cost of the ticket

EV = (1/1000 * $375) - $5

EV = $0.375 - $5

EV = -$4.625

Step-by-step explanation:

Kayden's math teacher said that each question answered correctly on a test would be worth 7 points. Answer the questions below regarding the relationship between the number of questions correct and the score on the test.

Since 00 questions correct gets you 00 points on the test, the function will have a yy-intercept of 0.0.

The rate at which points are earned is 7 points per question, so the slope of the function should be 7.7.

\text{Function Rule:}

Function Rule:

V(x)=7x

V(x)=7x

Plug x=11 Into Rule:

V(11)=7(11)=77

Correct Answer:

The independent variable, x, represents the number of questions correct, and the dependent variable is the score on the test, because the score on the test depends on the number of questions correct.

A function relating these variables is V(x) =V(x)= 7x7x.

So V(11) =V(11)= 7777, meaning 1111 questions correct will earn 7777 points on the test

The dimensions of the classroom are a width is 5 m and a length is 9 m.

We have been given that the width of a classroom is 4m less than the length its area is 45m², then.

L= 4 + W

Area = 45, so

L x W = 45

Now substituting the value of L, we get.

(4+W) W=45,

Now simplifying this we get.

4W + W² =45

W² + 4W - 45 = 0, this is a quadratic equation

Now solving this we get the factors 9 and -5,

(W+9) and (W-5) = 0

Thus, W= -9 or W= 5, since the width cannot be negative,  

So, it is width = 5

So, length = 9 m

In physics and arithmetic, the dimension of a mathematical space (or item) is informally defined as the minimal range of coordinates to specify any factor within it. therefore, a line has a dimension of one (1D) due to the fact handiest one coordinate is wanted to specify a factor on it – for instance, the point at 5 on more than a few lines. A floor, together with the boundary of a cylinder or sphere, has a size of two (2d) because two coordinates are needed to specify a point on it – for example, both a latitude and longitude are required to locate a point on the floor of a sphere. A two-dimensional Euclidean area is a -dimensional area on the aircraft. The internal of a dice, a cylinder, or a sphere is 3-dimensional (3-d) due to the fact 3 coordinates are had to find a factor inside these spaces.

In classical mechanics, area and time are distinct classes and seek advice from absolute space and time. That theory of the sector is a four-dimensional space however not the only one that was discovered as essential to explain electromagnetism.

Since the triangles are similar, the side lengths are proportional.  One way we can solve this is by finding the scale factor for the triangle on the left to the triangle on the right.  We can use the two corresponding sides that we know.

Let x = the scale factor

385x = 175  Divide both sides by 385

x = [tex]\frac{175}{385}[/tex]  Simplify by dividing the numerator and the denominator by 35

x = [tex]\frac{5}{11}[/tex]

I think -1.5 -0.1 0.8 1.1

Answer:

-1.5 || -0.1 || 0.8 || 1.1

Explanation:

Since it is from least to greatest, let's compare the 2 negative numbers -1.5 and -0.1.

-1.5 has a 1 in its first place while -0.1 has a 0. This means that -1.5 is smaller because the further a number is on the negative number line the smaller it is.

So, -1.5 is the smallest, then -0.1.

-1.5 || -0.1

Now we compare the 2 positive numbers 0.8 and 1.1.

0.8 has a 0 in its first place and 1.1 has a 1 in its first place. Because the numbers are positive, the number with the biggest digit in in front of the decimal is greater.

So, in this case 1.1 is greater than 0.8.

0.8 || 1.1

In order it is:

When a number is exactly divided by a divisor, that divisor is known as a factor of that number.

Alternatively, a factor of a number is an exact divisor of the provided number.

A number's factors are either less than or equal to the supplied number; they cannot be bigger. Every number is a factor of itself, and the common factor of all numbers is 1.

A number can be divided exactly by numerous divisors if it is a multiple of the divisor, therefore when we determine the factors of two or more numbers, we discover that some factors are common. As an illustration, the factors of 35 are 1, 5, 7, 35 while those of 45 are 1, 3, 5, 9, 15, 45. 1 and.
