The linear function the model the problem is y = 2x + 5

A linear function is a type of mathematical function that can be represented by a straight line on a graph. It is defined by an equation of the form y = mx + c, where m is the slope of the line and c is the y-intercept (the point where the line crosses the y-axis). Linear functions have certain properties, such as the fact that they have a constant rate of change and that the graph of a linear function is always a straight line.

From the data;

slope (m) = 2

y - intercept = 5

The linear function will be y = 2x + 5

Plotting this on a graph using a graphing calculator, we can easily identify our y - intercepts and slope.

What is linear inequality?

In mathematics, inequality denotes a mathematical expression in which neither side is equal. In Math, an inequality occurs when a connection produces a non-equal comparison between two expressions or two integers. The equal sign "=" in the phrase is substituted by any of the inequality symbols, such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), or not equal to symbol (≠). In mathematics, there are three types of inequalities: polynomial inequalities, rational inequalities, and absolute value inequalities.

The symbols "< and '>' represent strict inequalities, whereas  ‘≤’ and ‘≥’ represent slack inequalities. A linear inequality appears to be a linear equation, however there is a difference in the formula.

Step-by-step explanation:

Point A on the number line represents the number fraction -1. Option A is correct.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
A number line goes from negative 1 to positive 1. There are 3 equal spaces between each number. Point A is 1 mark to the left of 0.
So on the number line, the numbers on the left of 0 follow the negative sequence, and the number to the right of the zero follows the positive sequence. Following the given condition, point A on the number line represents the number fraction -1.

Thus, Point A on the number line represents the number fraction -1.

To determine the radius of the sphere before you can determine its volume. You can calculate the diameter by taking the diameter of 29.5 inches and dividing it by pi.

Let the equation be

[tex]$\begin{gathered}C=\pi \times D \\\frac{29.5}{3.14}=\frac{1475}{157}=9.3949044585987261\end{gathered}$$[/tex]

Then divide the diameter by 2 to get the radius.

[tex]$\frac{\left(\frac{29.5}{3.14}\right)}{2}=\frac{1475}{314}=4.6974522292993631$$[/tex]

So we get a radius of about 4.70.

Then we Utilize the formula for the volume of a sphere which exists

[tex]$V=\frac{4}{3} \times \pi \times r^3$$[/tex]

Substituting in R for 4.69, we get

[tex]$\frac{4}{3} \times 3.14 \times\left(\frac{1475}{314}\right)^3=433.96579644880793$$[/tex]

What is slope - intercept form of line?

The slope intercept equation can be used to determine a straight line's general equation from its slope and the location of its y-axis intersection.

Y = mx + b is the slope intercept form equation.

One formula for figuring out a line's equation is the slope-intercept formula. A line with slope m and a y-intercept of b has a slope-intercept formula of y = mx + b. Any point on the line can be found at (x, y).

From graph we can see that the graph passing through the points (3, 0) and (0, 6).

We have to find the slope intercept form of line.

First to find the slope of the line.

m = [tex]\frac{y_2-y_1}{x_2-x_1} = \frac{6-0}{0-3}=\frac{6}{-3} = -2[/tex]

Slope of the line is -2.

Now consider, the point -slope form of the line

[tex]y-y_1=m(x-x_1)[/tex]

Plug [tex]m = -2, (x_1, y_1) = (3, 0)[/tex]

⇒

[tex]y-0=-2(x-3)\\y=-2x+6[/tex]

The 2007th digit to the right of 1/7 is 2

when we convert 1/7 in decimal we get

1/7= 0.14285714285714....

Here we can notice that 6 digits are recurring.

The recurring digits are 1,4,2,8,5,7

For 2007th place, we divide 2007 by 6

2007/6=333.4

Now, this quotient tells us the place of the digit after the decimal that will be present in 2007th place i.e., if the quotient was 0 the digit at 2007th place would be 1 again, if the quotient was 1 the digit at 2007th place would be 4 and so on.

The statement that is true about J and K is that the expected values of J and K will be equal, and the variability of J will be greater than the variability of K. (Option E)

The sample size of J is 40 and sample size of K is 100. According to the central limit theorem if there is a population with mean μ and standard deviation σ and sufficiently large random samples is taken from the population with replacement, then the distribution of the sample means will be approximately normally distributed. Based on the theorem, both J and K will have the same expected value or mean.

As the standard deviation is inversely proportional to the same size, as the sample size increases, the standard deviation and related variability decreases. Hence, the variability of J will be greater than variability of K.

What is frequency plot?

A frequency plot is a graphic data analysis approach for condensing information about a variable's distribution. The response variable is split into intervals of the same size (or bins). For every bin, the response variable's frequency is determined.

The vertical axis represents frequencies or relative frequencies, and the horizontal axis represents the response variable in the frequency plot (i.e., the mid-point of each interval).

The first graph accurately represents the quiz grades as the graph ranges from 0 to 100 and the markings on it are made from 10 to 70.

The second graph is not the accurate representation of the quiz grades because the graph is ranging from 0 to 50 but the quiz grades are ranging from 10 to 70.

The value of the car after 3 years is £ 9318.6.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is.

First, the value of car after one year

= 18000 x (1- 30%)

= 18000 x 70%

= 18000 x 0.7

= 12600

now, the value of car after two year

= 12600 x (1- 14%)

= 12600x 86%

= 12600x 0.86

= 10836

and, the value of car after three year

= 10836 x (1-14%)

= 10836 x 86%

= £ 9318.6

To find the inverse of a parent function, use the following steps:

1. Switch the x and y variables.

2. Solve the equation for y.

3. Replace y with f-1(x).

4. Simplify the equation.

The inverse of a parent function is a new function that is the "reverse" of the original function. This can be found by switching the x and y variables and solving for y. Once you have switched the variables and solved for y, replace y with f-1(x). This is the notation for the inverse of a function. Simplifying the equation will give you the inverse of the original function. For example, if the function is y = 2x + 1, first switch the variables to x = 2y + 1. Then solve for y to get y = (x - 1)/2. Replace y with f-1(x) to get f-1(x) = (x - 1)/2. Simplifying this equation gives you the inverse of the original function, f-1(x) = (x - 1)/2.
