To determine which two quantities are connected to one another and how, we must interpret the graph.

The graph's two variables are: Time and distance from Elena's home.

such that the time depends on how far you are from Elena's home.

How can one read a graph?

Only graph A has to be examined; note that she is returning from school and leaving for home; the graph begins at a high value and finishes at zero. Therefore, we might infer that the vertical zero stands for her house.

We are aware of two events: first, she leaves for home and must return to seek for something; this is depicted by the first "inverted peak" of graph A; second, we are aware of the constant line that shows the duration of her time spent in school looking for something in her locker.

She then returns home, makes a buddy, and visits the library (which is why the queue forms once more). She spends some time there before leaving (this is why the line is horizontal for some time). The final section of the line that crosses the horizontal axis symbolises her return home.

The two items shown in the graph are then:

Time and the vertical axis' distance from Elena's home

This implies that the distance to Elena's home depends on the passing of time.

The factorization of 4x² + 8x + 3 is (2x + 1)(2x + 3).

To factorize 4x² + 8x + 3, we can use the method of factoring by grouping.

We can begin by rearranging the terms to make it easier to see the common factors:

4x² + 8x + 3 = 4x² + 2x + 6x + 3

Then, we can factor out a common factor of 2x from the first two terms and a common factor of 3 from the last two terms:

4x² + 8x + 3 = 2x(2x + 1) + 3(2x+ 1)

Now, we can see that (2x + 1) is a common factors of 2x(2x + 1) + 3(2x+ 1), so we can factor them out:

4x² + 8x + 3 = (2x + 1)(2x + 3)

The length of arc LN of the circle M rounded to the nearest hundredth is 17.81.

We shall use the formula:

arc length = (arc angle/360) × 2 × 22/7 × radius

where arc angle is measured in degrees and radius is the distance from the center of the circle to the point on the circle where the arc begins.

If LM = 17 and is the radius, with the arc angle m ∠LMN = 60 then the arc length LN is derived as follows:

(60°/360°) × 2 × 22/7 × 17

60°/360° can be reduced to 1)6

1/6 × 2 × 22/7 × 17

2 can divide 6 to give;

There are four main ways to solve a system of equations: graphing, elimination, substitution, and matrices.

An equation is a mathematical statement that expresses the equality of two expressions. It consists of two expressions that use symbols, numbers, and/or variables to represent values or relationships between values. Equations are used to describe relationships between two or more unknowns, and can be used to solve for the unknowns. Equations can be as simple as 3+2=5 or as complex as solving for a variable in a multivariate polynomial.

Graphing is the most common and straightforward approach to solving a system of equations. This involves plotting each equation on a graph and then finding the point of intersection. This is the solution to the system of equations.

Elimination is a method of solving a system of equations by adding or subtracting equations in order to eliminate one of the variables. This leaves one equation with one variable, which can be solved to find the solution.

Substitution is another way to solve a system of equations, where one equation is solved for one variable, and then this value is substituted into the other equation to solve for the other variable.

The final method of solving a system of equations is using matrices. This involves writing the equations in the form of a matrix (a rectangular array of numbers) and then using matrix operations to solve for the variables. This method is often used in linear algebra.

These four methods can be used to solve a system of equations, depending on the complexity of the equations and the preference of the user.

So, our estimate for the number of students at the school who would say they play a sport or game outdoors 4 hours per week is 160 students.

In order to estimate the number of students at the school who would say they play a sport or game outdoors 4 hours per week, we can use the sample data provided and make an assumption about the larger population.

First, we can see from the table that 4 students out of the 25 surveyed, or 16%, reported playing a sport or game outdoors for 4 hours per week.

If we assume that this sample is representative of the larger population of 1000 students at the school, we can use this percentage to estimate the number of students who would report playing a sport or game outdoors for 4 hours per week.

To do this, we can multiply the total number of students at the school (1000) by the percentage of students in the sample who reported playing a sport or game outdoors for 4 hours per week (0.16).

1000 x 0.16 = 160

So, our estimate for the number of students at the school who would say they play a sport or game outdoors 4 hours per week is 160 students.

Keep in mind that this is an estimation based on a sample and there could be some degree of error. To reduce the error, it's better to survey a larger sample.

The score which Suzy Q would need on her 5th test to meet her goal is 86%.

In Mathematics, the average of these math test scores can be calculated by using the following formula:

Average = Sum of math test score/Number of math test scores

Note: Let the variable s represent the Suzy Q's score on the fifth (5th) test.

Substituting the given parameters into the average test scores formula, we have the following;

Average = (87 + 100 + 79 + 98 + s)/5

Average = (364 + s)/5

Since Suzy Q wants to obtain at least a 90% average on her 5 math tests, an inequality that represents this situation can be written as follows;

(364 + s)/5 ≥ 90

Answer:

16 books

Step-by-step explanation:

133$ - 5 dollars for shipping = 128$

128$ divided by 8 = 16

Therefore, the answer is 16 books.

The mean of the sampling distribution of the sample mean for samples of size 16 is 3.2 V16, which is equal to the population mean of 3.2 divided by the square root of 16 (V16). This represents the expected mean of the sample mean when samples of 16 are taken from the population.

Step 1: Calculate the population mean (μ):

μ = 3.2 pets per student

Step 2: Calculate the standard deviation of the population (σ):

σ = 1.7 pets per student

Step 3: Calculate the sample size (n):

n = 16 students

Step 4: Calculate the mean of the sampling distribution (μx):

μx = μ / √n

μx = 3.2 / √16

μx = 3.2 / 4

μx = 0.8

Therefore, the mean of the sampling distribution of the sample mean for samples of size 16 is 0.8.The mean of the sampling distribution of the sample mean for samples of size 16 is 3.2 V16. This is calculated by dividing the population mean (3.2 pets per student) by the square root of the sample size (16). The square root of 16 is 4, which gives us a final result of 0.8. This means that the expected mean of the sample mean when samples of 16 are taken from the population is 0.8. This is a useful measure for understanding the variability of the sample mean, as it indicates how much the sample mean is likely to vary from the population mean.

The size of angle y is 34°. The solution is obtained using arc of circle.

What is arc of circle?

The circumference of a circle's arc is referred to as its section or segment. A chord of a circle is a straight line that can be formed by joining the two ends of the arc. A semicircular arc is one that is exactly half the length of the circle.

We know that an arc's angle at the centre of a circle is twice as large as its angle everywhere else on the circle's perimeter.

So, 2∠CBA= 180°-124°

⇒ 2∠CBA= 56°

⇒ ∠CBA= 28°

Also, ∠BCA= 1/2 (reflex ∠AOB)

⇒ 2∠BCA= 360° - ∠AOB

⇒ ∠AOB = 360° - 2∠BCA

⇒ ∠AOB = 360° - 2(124°)

⇒ ∠AOB = 360° - 248°

⇒ ∠AOB = 112°

Now, in triangle AOB,

112°+2y= 180°

⇒ 2y= 180°-112°

⇒ 2y= 68°

⇒ y= 34°

Hence, the size of angle y is 34°.

Inconsistent means that it has no solution , i.e. the solution does not exist.

Consistent system means a solution of the equation exists.

Further, this is of type , a consistent system may have a unique solution or an infinite number of solutions where we need to assign an arbitrary value to a free variable.
