What is Linear Inequality?

A linear inequality is a mathematical inequality that incorporates a linear function. A linear inequality contains one of the inequality symbols. It displays data that is not equal in graph form.

Solution:

Following Mentioned are the sreps to solve Linear Inequality:

1. Solve for the variable - In order to solve the inequality, isolate the variable using the same algebraic procedures that you would use to solve an equation. Remember to reverse the inequality sign when multiplying or dividing by a negative value.

2. Graph the line on a coordinate plane - To do so, convert the inequality into an equation and graph it like you would any line equation. Plot the y-intercept first, then use the slope to graph the remaining points on the line.

3. Shade in the appropriate area

Answer:

7.25 each or 7.00 if rounded

Step-by-step explanation:

No the results did not deviate significantly from what would be expected due to chance.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean. The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

The total number of counters in the bag is given as follows:

23 counters.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

The probability of taking a blue counter is of 0.8, while there are 18 blue counters in the bag, hence the total number of counters in the bag is obtained as follows:

0.8 = 18/n

0.8n = 18

Answer:  89 will go in the box

This means the exact distance between the two given points is \(\sqrt{89}\) which approximates to roughly 9.4339811

===========================================================

Explanation:

To get that answer, we can apply the distance formula

(x1,y1) = (-1,-5) is the first point

(x2,y2) = (4,3) is the second point

Plug the coordinates into the distance formula

\(d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(-1-4)^2 + (-5-3)^2}\\\\d = \sqrt{(-5)^2 + (-8)^2}\\\\d = \sqrt{25 + 64}\\\\d = \sqrt{89}\\\\d \approx 9.4339811\\\\\)

--------------------------

Alternative Method:

You could also form a right triangle by adding the point (4, -5). The horizontal leg goes from (-1,-5) to (4,-5) which is a span of 5 units. The vertical leg goes from (4,-5) to (4,3) which is a span of 8 units. The hypotenuse is from (-1,-5) to (4,3) which is the distance we want to find.

After forming the triangle and determining the leg lengths, use the pythagorean theorem and you should get \(\sqrt{89}\) as the length of the hypotenuse. As you can probably guess, the distance formula is effectively a slight rephrasing the pythagorean theorem.

The constant of proportionality is, 7.17

What is constant of proportionality?

The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. The constant of proportionality may also be referred to as the constant ratio, constant rate, unit rate, constant of variation, or even the rate of change.

The constant of proportionality k can be written as, \(k = \frac{y}{x}\)

or it can also be written as,  y = kx.

Here the given equation is,  y = 7.17x

Compare it with the above equation, we get k = 7.17

Mario left 65 miles to reach his goal and m + 65 = 130 is the equation to show how many miles Mario has left to run this month to reach his goal

Two or more expressions with an Equal sign is called as Equation.

Given that the Mario set a goal to run 130 miles this month to prepare for a marathon.

He has run 65 miles in this month.

We need to find the equation to show how many miles Mario has left to run this month to reach his goal.

m+65=130

We can find the left out distance in miles.

Subtract 65 from both sides.

m=130-65

m=65

Hence, m + 65 = 130 is the equation to show how many miles Mario has left to run this month to reach his goal and Mario left 65 miles to reach his goal.

The equation in standard form of the circle with radius 8 and center located at (-6 , 3) is (x + 6)^2 + (y - 3)^2 = 64.

The standard form of the equation of  circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (-6 , 3)

r = 8

(x - -6)^2 + (y - 3)^2 = 8^2

Linear model

Step-by-step explanation:

A linear model models a real-life situation y = mx + b (m will be the constant rate of change and b is the initial or starting value)

A linear function that mimics a real-world scenario is known as a linear model.

A continuous response variable is described by a linear model as a function of one or more predictor variables. They can assist you in analyzing experimental, monetary, and biological data or in understanding and predicting the behavior of complex systems. A statistical technique used to build a linear model is called linear regression.

It is called a linear model because the formula indicates a link between the left and right sides that is established by "linear" or "constant" parameters for each term, which are then solved for to reduce the overall divergence of the data from the model.

By using a linear combination of predictor variables, linear models can be used to describe a response variable.
