The given statement, "in 2014 the number of mobile phones was greater than the planet's population" is true (T) because there were 5.8 billion mobile users globally, about 80% of the world's population, and they each had 1.5 devices.

In 2014, there were more mobile phones than there were people on the planet. This is because many people own more than one phone, either as a personal and work phone or as a backup device. Additionally, the rise of low-cost mobile devices in emerging markets, where many people were purchasing their first phones, contributed to the high number of mobile phones relative to the population.

This trend has continued, with the number of mobile phones in the world continuing to grow, outpacing population growth and driving down the cost of devices so that even more people have access to them.

The sample of conference attendees drawn by Pam, where she randomly selected 47 names out of a hat containing all the attendees' names, is likely to be unbiased.

To determine whether a sample is biased or unbiased, it is important to consider the method of sampling. In this case, Pam put all the names of the conference attendees into a hat and drew 47 names randomly. This method of random selection ensures that each attendee has an equal chance of being selected.

By employing a random sampling method, the sample is likely to be representative of the entire population of conference attendees. Random sampling helps minimize the potential for bias by ensuring that every individual has an equal opportunity to be included in the sample.

However, it is important to note that bias can still be introduced if there are other factors involved in the selection process. For example, if the names in the hat were not representative of the entire population (e.g., excluding certain demographics or groups), then the sample could be biased. But based on the given information, the method of randomly selecting 47 names from the hat suggests an unbiased sample.

What is a composite number?

A composite number is a positive integer greater than 1 that has more than two positive divisors, or in other words, a number that can be evenly divided by at least one number other than 1 and itself. Examples of composite numbers include 4, 6, 8, 9, 10, 12, and so on. In contrast, a prime number is a positive integer greater than 1 that has exactly two positive divisors, 1 and itself.

32 is composite because it is divisible by 2, 4, 8, and 16.

33 is composite because it is divisible by 3.

34 is composite because it is divisible by 2 and 17.

35 is composite because it is divisible by 5 and 7.

36 is composite because it is divisible by 2, 3, 4, 6, 9, and 12.

37 is prime because it is only divisible by 1 and 37.

38 is composite because it is divisible by 2 and 19.

39 is composite because it is divisible by 3 and 13.

Therefore, the composite numbers between 31 and 40 are: 32, 33, 34, 35, 36, 38, 39.

The 7th term of the sequence is 48.

Sequence is an ordered arrangement of elements. It is often used to refer to a series of related events, or occurrences, which take place in a logical order. This order can be used to describe a process, a set of instructions, or a mathematical pattern. In mathematics, a sequence is a collection of numbers or other objects that follow a certain pattern or order. Common examples of sequences include the Fibonacci sequence, the prime numbers, and the geometric sequence.

This can be found by calculating the difference between each pair of terms, which is 6, and then adding 6 to each successive term.

Therefore, the 7th term is 27 + 6 = 33, and 33 + 6 = 39, and 39 + 6 = 45, and 45 + 6 = 51, and 51 + 6 = 57, and 57 + 6 = 63, and 63 + 6 = 69. Rounded to the nearest integer, the 7th term is 48.

Answer:

dude where is the question

(a) The unbiased estimate of the total number of errors in the manuscript is approximately 75.83.

(b) Sample average of the errors estimator is used on it.

(c) Yes, this is unbiased for the actual variance of the estimator of the total number of errors

(a) Unbiased estimate of the total number of errors:

To estimate the total number of errors in the manuscript, we need to consider the design used, which involves selecting a systematic sample of pages. The design selects the page with the random number 6 and then includes every 10th page thereafter. We are given the number of errors on the sample pages: 1, 0, 2, 3, 0, and 1.

The average number of errors per page in the sample is calculated as the sum of the errors on the sample pages divided by the number of sample pages:

(1 + 0 + 2 + 3 + 0 + 1) / 6 = 7 / 6 ≈ 1.17.

Now, we can estimate the total number of errors in the manuscript by multiplying the average number of errors per page by the total number of pages:

1.17 * 65 = 75.83.

(b) Estimator used and its unbiasedness:

The estimator used in this case is the sample average of the errors per page, which is calculated by summing the errors on the sample pages and dividing by the number of sample pages. In this case, the person estimated the total number of errors in the manuscript as 75.83 using the formula: 65(1 + 0 + 2 + 3 + 0 + 1) / 6.

(c) Variance of the estimator and its unbiasedness:

The variance of an estimator measures the variability or spread of the estimator's values around its expected value. To estimate the variance of the estimator, the formula used is 65(65 - 6)(1.37) / 6, where 1.37 is the sample variance of the six error counts.

To have an unbiased estimate of the variance, we would need to divide the numerator by (n - 1), where n is the number of sample units. In this case, n is 6 since we have six sample pages.

Therefore, the estimated variance of the estimator provided, 65(65 - 6)(1.37) / 6, is biased for the actual variance of the estimator of the total number of errors.

Answer:

x = 0

Step-by-step explanation:

First, distribute the -4 to the parentheses:

-4 + 3x = 2x - 4(1 - 3x)

-4 + 3x = 2x - 4 + 12x

Then, add like terms:

-4 + 3x = 14x - 4

Solve for x:

3x = 14x

0 = 11x

0 = x

Answer:

x=0

Step-by-step explanation:

We are given the following equation and asked to solve. We must solve for x by isolating x on one side of the equation.

-4 + 3x= 2x-4(1-3x)

First, distribute the -4. Multiply each term inside the parentheses by -4.

-4+3x=2x + (-4*1) + (-4*-3x)

-4+3x= 2x -4 + (-4*-3x)

-4+3x= 2x-4+12x

Combine like terms on the right side of the equation. The terms 2x and 12x can be added.

-4+3x= (12x+2x)-4

-4+3x=14x-4

Next, subtract 3x to both sides of the equation.

-4+3x-3x=14x-3x-4

-4= (14x-3x)-4

-4= 11x-4

Next, add 4 to both sides of the equation.

-4+4=11x-4+4

-4+4=11x

0=11x

Finally, divide both sides of the equation by 11.

0/11= 11x/11

0/11=x

0=x

Answer:

y = - \(\frac{1}{5}\) x + 9

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x - 4 ← is in slope- intercept form

with slope m = 5

given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{5}\) , then

y = - \(\frac{1}{5}\) x + c ← is the partial equation

to find c substitute (10, 7 ) into the partial equation

7 = - \(\frac{1}{5}\) (10) + c = - 2 + c ( add 2 to both sides )

9 = c

y = - \(\frac{1}{5}\) x + 9 ← equation of perpendicular line

Step-by-step explanation:

To determine the normal and shearing stresses at point h located at the top of the outer surface of the pipe assembly, additional information about the forces applied to the assembly is required. Without this information, a specific calculation cannot be provided. However, I can explain the concept of normal and shearing stresses in a general context.

In engineering mechanics, normal stress refers to the force per unit area acting perpendicular to a surface. It is calculated by dividing the applied force by the cross-sectional area. Normal stress can be tensile (pulling apart) or compressive (pushing together) depending on the direction of the force.

Shearing stress, on the other hand, refers to the force per unit area acting parallel to a surface. It arises when two adjacent layers of a material slide or deform relative to each other. Shearing stress is calculated by dividing the applied shearing force by the cross-sectional area.

To determine the normal and shearing stresses at point h, the magnitude and direction of the applied forces, as well as the geometry of the assembly, need to be provided.

The normal stress at point h located at the top of the outer surface of the pipe can be determined using the formula σ = P/A, where P is the applied force and A is the cross-sectional area. The shearing stress can be calculated using the formula τ = V/Q, where V is the applied shear force and Q is the first moment of area.

To calculate the normal stress at point h, we need to consider the applied forces acting on the pipe assembly. If we have the axial force P applied at point h, the normal stress can be calculated using the formula σ = P/A, where A is the cross-sectional area of the pipe. Since the pipe has an inner diameter of 36 mm and an outer diameter of 44 mm, the cross-sectional area can be calculated as A = π/4 * (D_outer^2 - D_inner^2), where D_outer and D_inner are the outer and inner diameters, respectively.

To calculate the shearing stress at point h, we need to consider the applied shear force V. The shearing stress can be calculated using the formula τ = V/Q, where Q is the first moment of area. The first moment of area can be calculated as Q = π/4 * (D_outer^4 - D_inner^4), considering the same pipe dimensions as before.

By substituting the values of P, A, V, and Q into the respective formulas, you can determine the normal stress and shearing stress at point h, located at the top of the outer surface of the pipe assembly.

Step-by-step explanation:

The asymptotic notation relationship between the functions \(f(n) = n^3 (8 + 2 cos 2n)\) and \(g(n) = n^2 + 2n^3 + 3n\) is f(n) ∈ Θ(g(n)). Therefore, the growth rates of f(n) and g(n) are primarily determined by the cubic terms, and they grow at the same rate within a constant factor.

To determine the asymptotic notation relationship between the functions \(f(n) = n^3 (8 + 2 cos 2n)\) and \(g(n) = n^2 + 2n^3 + 3n\), we need to compare their growth rates as n approaches infinity.

Θ (Theta) Notation: f(n) ∈ Θ(g(n)) means that f(n) grows at the same rate as g(n) within a constant factor. In other words, there exists positive constants c1 and c2 such that c1 * g(n) ≤ f(n) ≤ c2 * g(n) for sufficiently large n.

o (Little-o) Notation: f(n) ∈ o(g(n)) means that f(n) grows strictly slower than g(n). In other words, for any positive constant c, there exists a positive constant n0 such that f(n) < c * g(n) for all n > n0.

ω (Omega) Notation: f(n) ∈ ω(g(n)) means that f(n) grows strictly faster than g(n). In other words, for any positive constant c, there exists a positive constant n0 such that f(n) > c * g(n) for all n > n0.

Now let's analyze the given functions:

\(f(n) = n^3 (8 + 2 cos 2n)\\g(n) = n^2 + 2n^3 + 3n\)

Since both functions have the same dominant term, we can say that f(n) ∈ Θ(g(n)) because they grow at the same rate within a constant factor. The other notations, o and ω, are not applicable here because neither function grows strictly faster nor slower than the other.

Answer:

x = - 1 , x = \(\frac{1}{3}\)

Step-by-step explanation:

assuming you require the solution to the equation

x(3x - 1) + (3x - 1) = 0 ← factor out (3x - 1) from each term

(3x - 1)(x + 1) = 0

equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

3x - 1 = 0 ( add 1 to both sides )

3x = 1 ( divide both sides by 3 )

x = \(\frac{1}{3}\)

To find the Maclaurin series for the given function f(x) = ln(1 + x^9), we can use the known Maclaurin series expansion for the natural logarithm function:

ln(1 + t) = t - (t^2)/2 + (t^3)/3 - (t^4)/4 + ...

Let's substitute t = x^9 into the formula and expand the series:

f(x) = ln(1 + x^9)

= x^9 - (x^9)^2/2 + (x^9)^3/3 - (x^9)^4/4 + ...

Simplifying the terms, we have:

f(x) = x^9 - x^18/2 + x^27/3 - x^36/4 + ...

Therefore, the Maclaurin series for f(x) = ln(1 + x^9) is:

f(x) = ∑ ((-1)^(n+1) * x^(9n))/(n), where n goes from 1 to infinity.
