The required, subtraction of 7x-9 from 2x² - 11 is 2x²-7x-2. Option B is correct.

Arithmetic is a branch of mathematics that deals with the study of numbers, their properties, and their operations. It involves the basic operations of addition, subtraction, multiplication, and division, as well as more advanced operations such as exponents, roots, logarithms, and trigonometric functions.

Here,

To subtract 7x-9 from 2x² - 11, we need to distribute the negative sign across 7x and 9, and then combine like terms.

=2x² - 11 - (7x - 9)

= 2x² - 11 - 7x + 9

= 2x² - 7x - 2

Therefore, the answer is 2x²-7x-2.

Step-by-step explanation: Because

Answer: Since the sample size is large (n > 30) and the population standard deviation is known, we can use the normal distribution to approximate the sampling distribution of the mean.

The standard error of the mean is the standard deviation of the sampling distribution of the mean, and it can be calculated as follows:

standard error of the mean = standard deviation / sqrt(n)

Plugging in the given values, we get:

standard error of the mean = 7 inches / sqrt(51) = 1.17 inches

The probability that x is within 0.5 inches of the claimed population mean (15 inches) is equal to the probability that x is between 14.5 inches and 15.5 inches. We can use the normal distribution to find this probability by standardizing the range 14.5 inches to 15.5 inches and using a z-table or a calculator to find the corresponding probability.

The standardized value for 14.5 inches is (14.5 - 15) / 1.17 = -0.43, and the standardized value for 15.5 inches is (15.5 - 15) / 1.17 = 0.43.

The probability that x is between -0.43 and 0.43 is equal to the area under the standard normal curve between these two values. Using a z-table or a calculator, we can find that this probability is 0.6915.

Therefore, the probability that x is within 0.5 inches of the claimed population mean is approximately 0.6915, which is the final answer.

Which is not an equation of the line going through (3, -6) and (1, 2)?

A. y=-4x+6

B. y+ 6 = -4(x- 3)

C. y- 1=-4(x-2)

D. y - 2 = -4(x-1)

An equation of the line going through two points (x1, y1) and (x2, y2) can be written in the form y - y1 = m(x - x1), where m is the slope of the line. The slope of the line can be calculated using the formula:

m = (y2 - y1) / (x2 - x1)

Plugging in the values for (x1, y1) and (x2, y2) from the problem, we get:

m = (2 - (-6)) / (1 - 3) = 8/ -2 = -4

Therefore, an equation of the line going through (3, -6) and (1, 2) is of the form y - (-6) = -4(x - 3).

Option B is of this form, so it is an equation of the line going through (3, -6) and (1, 2). The other options are not of this form, so they are not equations of the line going through (3, -6) and

The calculation finds that by substituting '-6' for 'x' in the equation g(x)=5x-5, we find the value of g(-6) to be -35.

The question asks us to find the value of g(-6) for function g(x)=5x-5. To do this, we substitute '-6' for 'x' in the equation. The calculation is as follows:

Answer:

m<P = 31°

Step-by-step explanation:

Use this symbol < for angle, not <.

<P and <Q are complementary.

That means that their measures add to 90°.

m<P + m<Q = 90°

Now we substitute 7x + 3 for m<P and 16x - 5 for m<Q.

7x + 3 + 16x - 5 = 90

Solve for x.

23x - 2 = 90

23x = 92

x = 4

m<P = 7x + 3 = 7 × 4 + 3 = 31

What is Vertex of graph?

A vertex or node is the basic building block of a graph in discrete mathematics, and more precisely in graph theory. An undirected graph is made up of a set of vertices and a set of edges, whereas a directed graph is made up of a set of vertices and a set of arcs.

According to question

when f(x) = 0

that's the minimum point, the vertex, or the intersection of two lines,  g(x) = 0.25x − 0.75 and h(x) =  0.75 - 0.25x

Therefore

find the intersection of Two line which are

⇒ y = x/4 - 3/4

⇒ 4y = x - 3 → First line

⇒ y = 3/4 - x/4  

⇒ 4y = 3 - x → Second line

So x - 3 = 3 - x

2x = 6 ,

x = 3

The equation which can be used to determine n, the number of calories in each chicken nugget would be 193.5+12 n=288.5+8n

And n = 24.1

Option (C) is correct.

What is a linear equation?

A linear equation is an equation that describes a straight line. Linear equations have the form y = mx + b, where x and y are variables and m and b are constants. The constant m is the slope of the line, and the constant b is the y-intercept, which is the point where the line crosses the y-axis.

To derive this equation, we can start with the fact that the two meals have the same number of total calories. This means that the number of calories in the first meal is equal to the number of calories in the second meal. We can represent this relationship with the equation:

8 nuggets * calories/nugget + 193.5 calories = 12 nuggets * calories/nugget + 288.5 calories

We can then rearrange the terms on the left and right sides of the equation to get the equation in the form given in option C:

193.5 + 12 n = 288.5 + 8 n

Finally, we can solve this equation for n by subtracting 8n from both sides and then dividing both sides by 4:

n = (193.5 - 288.5) / 4 = (-95) / 4 = -23.75

Therefore, the number of calories in each chicken nugget is 24.1 calories.

Hence, option (C) is correct.

A Confidence Interval shows the joint or bivariate relationship between two categorized (nominal and/or ordinal) variables.

Data that is labeled without using quantitative data is known as nominal data.

A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number.

A variable is categorical unless it has a numerical value, in which case it is referred to as a quantitative variable.

The category and quantitative variables are now classified as follows:

Duration is a quantitative variable with interval as its unit of measurement.

Ratings are categorical variables with an ordinal level of measurement.

The degree of measurement for the categorical variable "voting status" is nominal.

Ordinal data are those that can be arranged.

The highest and smallest known values are continuous and discrete values for interval data, respectively. The order is clear here. Here, the distinction between two values means something.

All of the characteristics of interval data apply to ratio data, plus it has the definition of zero(0), meaning that no points are included. For instance, height, weight, etc.

Because ratio includes both continuous and discrete data, it is likely that the difference between any two numbers won't be the same.

It is interval data since everyone knows when a class starts and when it ends, and it also has these two times. for instance, between 9:00 to 10:00

Nominal because the information is categorical.

Ordinary, given that we may get quality products here. Good, acceptable, or poor.

Ordinal because the marks can be arranged.

Ordinary since we can arrange the ages.

Line symmetry; rotational symmetry; the reflection in the line x = 0, the reflection in the line y = 0 the reflection in the line y = x and the reflection in the line y = -x map the square onto itself; the rotations of 90°, 180°, 270° and  around the point ( 0 , 0 ) map the square onto itself.

Coefficient Cn is determined by Cn = 1/2 ∫[0,2] (x+2)yn(x) dx

To find the coefficients Cn of the eigenfunction expansion of a function f(x), f(x) must be expanded with the eigenfunction yn(x). The expansion of f(x) with respect to the eigenfunction yn(x) is given by

f(x) = Σ[∞], n=1 cnyn(x)

To find the coefficient cn, we need to compute the dot product of f(x) and yn(x).

cn = (f,yn) = ∫[0,4]f(x)yn(x)dx

Since the eigenfunctions yn(x) are orthonormal, the scalar product is given by

cn = ∫[0,4]f(x)yn(x)dx = ∫[0,2]f(x)yn(x)dx + ∫[2,4]f(x)yn(x)dx

Since f(x) = 2/2 x for x in [0,2] and f(x) = 2 for x in [2,4], compute the coefficient cn as I can do it.

cn = ∫[0,2](2/2x)yn(x)dx + ∫[2,4](2)yn(x)dx

= ∫[0,2]xyn(x)dx + ∫[2,4]2yn(x)dx

= 1/2 ∫[0,2] (xyn(x) + 2yn(x)) dx

= 1/2 ∫[0,2] (x+2)yn(x) dx

Therefore, the coefficient Cn is given by

Cn = 1/2 ∫[0,2] (x+2)yn(x) dx
