The probability of 4 defective cell phones in a sample of 25 can be found using the binomial probability formula and is equal to 0.0263.

Probability is a branch of mathematics that deals with calculating the likelihood of a given event occurring. In probability, we calculate the number of ways an event can happen and divide it by the total number of possible outcomes.

Probability ranges from 0 to 1, with 0 indicating no chance of occurrence and 1 indicating that the event will definitely occur.

If there are only two possible outcomes in a given event, the binomial probability formula is used to calculate the probability of the event happening.

The binomial probability formula is given by: P(X = x) = (nCx)px(1 - p)n - x

Where, P(X = x) is the probability of x successes in n trials

nCx is the number of ways x successes can occur in n trials

px is the probability of a single success in a given trial(1 - p)n - x is the probability of the remaining trials being failures.

The probability of 4 defective cell phones in a sample of 25 can be calculated using the binomial probability formula.

P(X = 4) = (25C4)(0.06)4(0.94)21 = 0.0263.

Therefore, the probability of 4 defective cell phones in a sample of 25 is 0.0263.

The length of the second parallelogram is 2 cm.

What are parallelograms ?
A parallelogram is a quadrilateral with opposite sides parallel and equal in length. It has two pairs of parallel sides and opposite angles are equal. Some common properties of parallelograms include:

According to the question:
To solve for x, we need to use the fact that opposite sides of a parallelogram are equal in length.

For the first parallelogram, we know that the width is 4 cm and the length is 6 cm. Therefore, the opposite side lengths are also 4 cm and 6 cm.

For the second parallelogram, we know that the width is 6 cm. Since the opposite sides are equal in length, the length of the parallelogram must be x cm.

So, we have:

Width of first parallelogram = Width of second parallelogram

4 cm = 6 cm

Length of first parallelogram = Length of second parallelogram

6 cm = x cm

Simplifying the first equation, we get:

2 cm = x

Therefore, the length of the second parallelogram is 2 cm.

Ten chairs are arranged in a circle. The number of subsets of this set of chairs that contain at least three adjacent chairs is 310.

The given that 10 chairs arranged in a circle.

            Now we have to find the number of subsets of this set of chairs that contain at least three adjacent chairs.

           To solve this, we can use the concept of permutations and combinations. The first step is to consider the number of ways in which three chairs can be selected and arranged in a subset that is adjacent to each other.

           This can be done in 10 different ways, as there are 10 chairs in total and we can select any one of them as the starting point.

           The next step is to consider the number of ways in which we can add additional chairs to this subset. For example, we can add a fourth chair to the subset in two different ways: either to the left of the first chair or to the right of the third chair.

            Similarly, we can add a fifth chair to the subset in four different ways, a sixth chair in six different ways, and so on. Using this logic, we can create the following table:

                    Length of subset number of ways to select the subset number of ways to add chairs

           Total number of subsets31 (adjacent)

                                = 10  ---43 (adjacent) 10*2

                                =20---55 (adjacent)10*4

                                =40---67 (adjacent)10*6

                                =60---79 (adjacent)10*8

                               =80---810 (adjacent)10*10

                               =100---

              As we can see from the table, the total number of subsets that contain at least three adjacent chairs is given by:

           Total number of subsets = 10 + 20 + 40 + 60 + 80 + 100

                                                     = 310

Therefore, the equation of the line is y = 6x + 1, in slope-intercept form.

In mathematics, an equation is a statement that shows the equality of two expressions. An equation usually contains one or more variables, which represent unknown values that we are trying to solve for. Equations can also be more complex, involving multiple variables and operations such as exponents, logarithms, and trigonometric functions. Solving equations is an important part of mathematics, and has many practical applications in science, engineering, and everyday life.

Here,

The equation of a straight line in slope-intercept form is y = mx + b, where m is the gradient (or slope) of the line, and b is the y-intercept (where the line crosses the y-axis). We are given that the gradient of the line is 6, and that it passes through the point (3, 19). We can use this information to find the equation of the line. First, we can use the point-slope form of the equation of a line to find the equation of the line that passes through the point (3, 19) with a gradient of 6. The point-slope form is:

y - y1 = m(x - x1)

where (x1, y1) is the point the line passes through, and m is the slope of the line.

Substituting the values we know, we get:

y - 19 = 6(x - 3)

The solutions to the trigonometric equations [tex]2cos(x) - \sqrt{30} = 0[/tex] in the interval [tex][0, 2\pi)[/tex] are x ≈ [tex]0.5514 + 2n\pi[/tex], where n is an integer.

Given that the equation  [tex]2cos(x) - \sqrt{30} = 0[/tex] in the interval [tex][0, 2\pi)[/tex]

To find all the solutions to the equation  [tex]2cos(x) - \sqrt{30} = 0[/tex] in the interval [tex][0, 2\pi)[/tex] ,  solve for x by isolating the cosine term and then applying the inverse cosine function.

Here are the steps to solve the equation:

Add [tex]\sqrt{30}[/tex] to both sides:

[tex]2cos(x) = \sqrt{30}[/tex]

Divide both sides by 2:

[tex]cos(x) = \sqrt{30} / 2[/tex]

Find the inverse cosine ([tex]cos^{-1}[/tex]) of both sides:

[tex]x = cos^{-1}(\sqrt{30} / 2)[/tex]

To determine the values of x in the interval [tex][0, 2\pi)[/tex] that satisfy the equation.

Evaluate [tex]cos^{-1}(\sqrt{30} / 2)[/tex] to find its approximate value.

[tex]cos^{-1}(\sqrt{30} / 2) = 0.5514[/tex] radians

Since the cosine function has a periodicity of [tex]2\pi[/tex], we can find other solutions by adding multiples of [tex]2\pi[/tex] to the initial solution.

So, the solutions in the interval  [tex][0, 2\pi)[/tex] are:

x ≈ 0.5514 radians

x ≈ [tex]0.5514 + 2\pi[/tex]

x ≈ [tex]0.5514 + 4\pi[/tex]

...

To simplify, express the solutions as:

x ≈ [tex]0.5514 + 2n\pi[/tex]

where n is an integer.

Therefore, the solutions to the trigonometric equations [tex]2cos(x) - \sqrt{30} = 0[/tex] in the interval [tex][0, 2\pi)[/tex] are x ≈ [tex]0.5514 + 2n\pi[/tex], where n is an integer.

The sum of the circumscribed angle m∠ECD and central angle m∠EAD for five different data sets are 90°, 90°,120°,150°,180°.

A central angle is an angle in a circle that has its vertex at the center of the circle. Its arms, which are the two rays that make up the angle, both pass through points on the circumference of the circle.

m∠ECD  m∠EAD  m∠ECD + m∠EAD

60°  30°    90°

100°  20°    120°

140°  10°    150°

180°  0°    180°

The measure of the circumscribed angle, ∠ECD, is the angle formed by the intersection of two lines, AB and CD.

The measure of the central angle, ∠EAD, is the angle formed by the intersection of the lines AB and ED.

The relationship between the circumscribed angle and the central angle can be explored by moving point B to various different locations on the coordinate plane between A and C.

By doing so, both the circumscribed angle and the central angle can be measured.

From the table above, it can be seen that the sum of the measures of the circumscribed angle and the central angle is always equal to 90°.

This is because the circumscribed angle and the central angle are supplementary angles, meaning that the sum of their measures always equal to 180°.

In this case, since the sum of the measures of the circumscribed angle and the central angle is always equal to 90°, the measures of the circumscribed angle and the central angle themselves must always add up to 90°.

Random sampling is used to ensure that the sample is representative of the population, while random assignment is used to control for extraneous variables and increase the internal validity of the study.

Random sampling and random assignment are two distinct procedures that are often used in research studies, and it's important to understand the difference between them.

Random sampling refers to the process of selecting individuals or units from a larger population in such a way that every member of the population has an equal chance of being included in the sample. Random sampling is used to ensure that the sample is representative of the population and that the results can be generalized to the larger population.

Random assignment, on the other hand, refers to the process of assigning participants to different experimental conditions in a way that is completely random. This means that every participant has an equal chance of being assigned to any condition. Random assignment is used to control for extraneous variables that could influence the results of the study. By randomly assigning participants to conditions, researchers can be more confident that any differences observed between the groups are due to the manipulation of the independent variable, rather than pre-existing differences between the participants.

The polynomial function f(x) = x³ - 5x² - 61x - 55 has the following

Real zeros: x = -5, x = -1, and x = 11.  

To find the rational zeros of a polynomial, we use the rational zeros theorem. We look at the factors of the leading coefficient and the factors of the constant coefficient.

The  states that if a polynomial function is defined as P(x) = anxn + an-1xn-1 + ... + a1x + a0 with integers, then each rational zero of the polynomial can be expressed in the form p/q where p is a factor of a0 and q is a factor of an.

For example, if P(x) = 2x³ - 5x² + 3x + 6 then p can be any factor of 6 and q can be any factor of 2.

The factors of the leading coefficient, 1, and the factors of the constant coefficient, -55, are: ±1, ±5, ±11, ±55. So the possible rational zeros are: ±1, ±5, ±11, ±55, ±1/1, ±5/1, ±11/1, ±55/1, ±1/1, ±5/1, ±11/1, ±55/1.

Simplifying the results, we have that the potential rational zeros are: ±1, ±5, ±11, ±55, ±1, ±5, ±11, and ±55.

By testing each possible rational zero, we find that x = -5, x = -1, and x = 11 are the real zeros of f(x).

Hence, using synthetic division, we get:

(x + 5)(x + 1)(x - 11) = x³ - 5x² - 61x - 55

Thus, the function can be factored over the real numbers as

f(x) = (x + 5)(x + 1)(x - 11).
