If the perimeter of the figure below is 20 feet, what is the area of the figure?

Answer:

The correlation between hour of the day and the speed over the limit at which the motorist is ticketed is weak positive correlation.

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

The types of correlation coefficient are:

The correlation coefficient value between the hour of the day and the speed over the limit at which the motorist is ticketed is:

r = 0.12.

The value of r lies between:

0 < 0.12 < 0.30

Thus, the correlation between hour of the day and the speed over the limit at which the motorist is ticketed is weak positive correlation.

An essential concept in mathematics and can be applied to a variety of fields such as physics, economics, and engineering.

The slope of a line in a Cartesian plane is a numerical representation of its steepness and inclination relative to the x-axis.

The slope of a straight line refers to the rise or fall of the y-coordinate as it moves from left to right along the x-axis.

There are a few different ways to interpret the slope of a line, but generally it can be thought of as the rate at which the dependent variable changes with respect to the independent variable.
When the slope is positive, the line rises from left to right, indicating that the dependent variable is increasing as the independent variable increases.

In other words, there is a direct relationship between the two variables.

Conversely, when the slope is negative, the line falls from left to right, indicating that the dependent variable is decreasing as the independent variable increases.

This means that there is an inverse relationship between the two variables.
The magnitude of the slope can also provide information about the relationship between the variables.

If the slope is close to zero, then the relationship between the two variables is weak or nonexistent.

However, if the slope is large in magnitude (i.e. close to 1 or -1), then there is a strong relationship between the variables.

A slope of zero indicates that there is no change in the dependent variable as the independent variable changes, while a slope of undefined means that the line is vertical and has no slope.

Answer:

28v + 16w - 32

Step-by-step explanation:

The simplified answer is 28v + 16w - 32.

The distributive property states that multiplying the sum of two or more addends by a number yields the same outcome as multiplying each addend separately by the number and combining the resulting products.

When you multiply a value by a sum, the distributive property of multiplication over addition is used.

Given:

4(7v+4w-8)

According to distributive property, we have

ax( b+ c)= (a x b)+ ( a x c)

Now, 4(7v+4w-8)

= 4x 7v+ 4 x 4w - 4 x8

= 28v + 16w - 32

Hence, the simplified answer is 28v + 16w - 32.

The side a = 19.16, and the angles B and C are 23.75 and 129.25 all rounded to 2 decimal place using the cosine and sine rule.

In trigonometry, the cosines rule relates the lengths of the sides of a triangle to the cosine of one of its angles. While sine rule is a relationship between the size of an angle in a triangle and the opposing side.

Considering the given triangle, side a is calculated with cosine rule as follows;

a² = b² + c² - 2(b)(c)cosA

a² = 17² + 13² - 2(17)(13)cos27°

a² = 367.188

a = 19.1603 {take square root of both sides}

by sine rule;

19.1603/sin27° = 17/sinB

sinB = (17 × sin27)/19.1603 {cross multiplication}

B = sin⁻¹(0.4028)

B = 23.7533

C = 180 - (27 + 23.7533) {sum of interior angles of a triangle}

C = 129.2467

With proper application of the cosine and sine rule, we can conclude the value of the side a of the triangle is approximately 19.16, and the angles B and C are 23.75 and 129.25 all rounded to 2 decimal place.

Of all the factoring methods covered in this chapter, the easiest method for me is the GCF (Greatest Common Factor) method. This method involves finding the largest number that can divide all the terms in an expression evenly. It is relatively straightforward because it only requires identifying the common factors and then factoring them out.

On the other hand, the hardest method for me is the ‘ac’ method. This method is used to factor trinomials in the form of ax^2 + bx + c, where a, b, and c are coefficients. The ‘ac’ method involves finding two numbers that multiply to give ac (the product of a and c), and add up to give b. This method can be challenging because it requires trial and error to find the correct pair of numbers.

To summarize, the GCF method is the easiest because it involves finding common factors and factoring them out, while the ‘ac’ method is the hardest because it requires finding specific pairs of numbers through trial and error. It is important to practice and understand each method to become proficient in factoring.

The cosine of the angle between the two vectors is:
cosθ = 60 / √5501

The numerator and denominator do not share any factors, we cannot simplify the fraction any further.

To find the cosine of the angle between two vectors, we first need to find the dot product of the two vectors and then divide it by the product of their magnitudes. Let's start by finding the dot product:

(i + 6j) · (10j + 7k) = 0 + 60 + 0 = 60

Next, we need to find the magnitudes of the two vectors:

|i + 6j| = √(1² + 6²) = √37

|10j + 7k| = √(0² + 10² + 7²) = √149

Now we can plug in the values into the cosine formula:

cosθ = (i + 6j) · (10j + 7k) / |i + 6j| |10j + 7k|
     = 60 / (√37)(√149)
     = 60 / √5501

Finally, we can see that cosθ is equal to 1 when the angle between the two vectors is 0. This makes sense since i + 6j and 10j + 7k are not perpendicular to each other.

This solution represents a linear combination of exponential functions, where each component of x(t) is determined by the corresponding component of C and the matrix exponential of At.

To find the general solution to the system x' = Ax, we can express the solution in terms of the matrix exponential. The matrix exponential of At, denoted as e^(At), is defined as the power series expansion of the exponential function applied to the matrix At. It can be computed using various techniques, such as diagonalization, Jordan decomposition, or power series.

The general solution to the system x' = Ax can then be written as x(t) = Ce^(At), where C is a constant matrix. This solution represents a linear combination of exponential functions, where each component of x(t) is determined by the corresponding component of C and the matrix exponential of At.

The matrix exponential e^(At) has properties that are analogous to those of the scalar exponential function.

Comparing the functions f(x) = ln (x) and \(f^{-1}(x) = e^x\), we can conclude that the domain of \(f^{-1}(x)\) is all real numbers and the range is all real numbers greater than 0.

Given function is the logarithmic function f(x) = ln(x).

Now, f(x) has a domain(D) of all real numbers greater than zero and a range(R) of all real numbers.

i.e., f : D → R defined by f(x) = ln(x)

So if an inverse exist for f(x), then, \(f^{-1}(x)\) will have R as its domain and D as its range.

i.e.,  \(f^{-1}\) : R → D defined by \(f^{-1}(x) = e^x\).

Because f( \(f^{-1}(x)\) ) = ln(\(e^x\)) = x, that is the identity function.

So \(e^x\) is the inverse of ln(x).

1200/600= 1/2= 0.50=50%

This probability is greater than 1, which is not possible.

This suggests that there may be an error in the problem statement, or that some additional information is required to correctly solve the problem.

The probability of a store being a Kwik Save is:

P(Kwik Save) = 1000 / (1000 + 424) = 1000 / 1424 = 0.7037

The probability of a store closing, given that it is a closing store, is:

P(closing| Kwik Save) = 107 / (107 + 324) = 107 / 431 = 0.2488

The probability of a store being a closing store is:

P(closing) = (107 + 324) / (1000 + 424) = 431 / 1424 = 0.3029

The probability of a randomly chosen store being either closing or Kwik Save is:

P(closing or Kwik Save) = P(closing) + P(Kwik Save) - P(closing and Kwik Save)

= 0.7037 + 0.3029 - (107 / 1424)

= 0.8997

The probability that a randomly selected store is not closing given that it is a Somerfield is:

P(not closing| Somerfield) = 1 - P(closingl Somerfield)

To find P(closing| Somerfield), we can use Bayes' theorem:

P(closing| Somerfield) = P(Somer field| closing) * P(closing) / P(Somerfield)

P(Somerfield| closing) is the probability that a store is a Somerfield given that it is closing.

Since all the Somerfield stores are closing, this probability is 1.

P(Somerfield) is the probability that a store is a Somerfield.

It is:

P(Somerfield) = 424 / (1000 + 424) = 424 / 1424 = 0.2980

Therefore,

P(closing| Somerfield) = 1 * 0.3029 / 0.2980 = 1.0151.

Use the appropriate angle rule(s) to solve angles in Mathematical problems.

When two rays are united at a common point, an angle is created. The two rays are referred to as the arms of the angle, while the common point is referred to as the node or vertex. The symbol '∠' stands for the angle. The Latin word "Angulus" is where the term "angle" originated.

These angles are usually measured in degrees like 45°, 30°, 50°, 15°, 110°, 75° and 120° etc.  

Here are some key points and rules to solve angles in Maths

Angles on a straight line

A straight line's angles always add up to 180 degrees. We use this rule to solve angles lying on a straight line.

Angles around a point or angle in a circle

Angles that circle a point always equal 360 degrees. We use this rule to solve angles related to circles, sectors, closed polygons, etc.  

Supplementary angles:

The pair of angles that are added up to 180° are known as Supplementary angles. Example, 150°, 30°;  120°, 60°;  100°, 80° etc.

Complementary angles

The pair of angles that are added up to 90° are known as angles Complementary angle. Examples, 45°, 45°; 50°, 40°; 60°, 40° etc.

If you have exactly one right angle, then it is possible to have no parallel lines.   See the diagram below. Refer to the upper figure.

If you had exactly 2 right angles, then that would form a trapezoid. A trapezoid has exactly one pair of parallel lines.

If you had 4 right angles, then it would form a rectangle. Any rectangle is a parallelogram, so we have 2 pairs of parallel lines by this point.

It's not possible to have a quadrilateral with exactly 3 right angles (and the fourth angle is some non-right angle). This is because all four angles of any quadrilateral must add to 360 degrees.
