Answer:

3 + n = 2n - 5

Step-by-step explanation:

let 'n' equal 'a number'

'more than' implies 'addition', so 3 + n

'is' in math implies 'equals', so 3 + n =

'double the number' means to multiply it by 2

'less than' implies 'subtraction'

So final result is:

3 + n = 2n - 5

The probability that any given bit received by the smartphone is erroneous is 1%, or equivalently, the probability that any given bit is correct is 99%.

The probability that the 27th bit is the first erroneous bit means that the previous 26 bits were all correct. The probability of this happening is:

P(all previous 26 bits are correct) = (0.99)^26

Now, given that the previous 26 bits were all correct, the probability that the 27th bit is erroneous is simply 1% or 0.01.

Therefore, the overall probability that the 27th bit received by the smartphone is the first erroneous bit is:

P(27th bit is first erroneous bit) = P(all previous 26 bits are correct) x P(27th bit is erroneous | all previous 26 bits are correct)

= (0.99)^26 x 0.01

= 0.0081 or approximately 0.81%

The test statistic is, -2.06.

What is test statistic?

A programme and any related documentation are examined during static testing, a type of software testing that does not call for the programme to be run. Software testing also includes dynamic testing, which involves interacting with the application as it is being used.

Given: Americans work less than 40 hours a week on average in 1977?

In 1977, the GSS included questions about the number of hours that the respondent worked per week.

The average number of hours worked per week was 34. 61 hours with a standard deviation of 14. 77 hours.

A sample of 32 respondents was questioned.

So, the test statistics is,

Z = (x bar - μ)/(σ /√n)

 = (34.61 - 40)/(14.77/sqrt(32))

Z = -2.06

Hence, the test statistics is -2.06.

Answer:

no

Step-by-step explanation:

No, a cylinder cannot produce a cross section that has 4 straight sides. A cylinder is a three-dimensional object that has a circular base and a curved surface that extends from the base to the top. Any cross section of a cylinder taken parallel to its base will produce a shape that is congruent to the base, which is a circle. Therefore, any cross section of a cylinder will be a circle or an ellipse, which do not have straight sides.

On the other hand, a prism is a three-dimensional object that has two congruent parallel bases and flat, rectangular or parallelogram-shaped sides that connect the bases. A prism can produce a cross section that has 4 straight sides, which would be a rectangle or a parallelogram.

1) The equation is y = 50x + 125

2) On the image at the end.

3) The y-intercept is the initial amount and the slope is the amount he adds per week.

We know that he starts with 125 pounds, and then he adds 50 pounds per week, so after x weeks, he will have a total of:

y = 50x + 125

This is a linear equation with a slope of 50 and an y-intercept of 125.

The slope tells us how much he adds per week, the y-intercept tells us the initial amount.

To graph this line find two points on the line, you can do that by evaluating:

if x = 0

y = 50*0 + 125 = 125 ---> we have (0, 125)

if x = 1

y = 50*1 + 125 = 175 ---> we have (1, 175)

Now graph these two points and connect them with a line.

We may build up a proportion and solve for the scale model radius of Neptune using the ratio between the radii of the two planets and the known scale model radius of the Earth. The scale model of Neptune that is produced has a radius of around 9.7 cm.

We may take advantage of the fact that the ratio between the two planets' radii and the ratio between their respective scale model radii is the same. Let's name the Neptune scale model radius "r" Then, we may set up the ratio shown below:

Neptune's radius is equal to the product of Earth's radius and its scale model.

With the provided values, we may simplify and obtain:

24620 km / 6370 km equals 2.5 cm / r

We obtain the following when solving for "r":

r = (24620 km * 2.5 cm) / (6370 km)

r ≈ 9.7 cm

Therefore, a scale model of Neptune would have to be drawn with a radius of approximately 9.7 cm.

The final equation for the tangent plane to the graph of f at the point (a, b) is z = 2e^a(x - a) - y + 2e^a - 2b. This equation represents the plane that is tangent to the graph of f at the specified point (a, b).

To find the equation for the tangent plane to the graph of the function f(x, y) = 2e^x - y at a given point (x0, y0), we need to calculate the partial derivatives of f with respect to x and y at that point.

The partial derivative of f with respect to x, denoted as ∂f/∂x or fₓ, represents the rate of change of f with respect to x while keeping y constant. Similarly, the partial derivative of f with respect to y, denoted as ∂f/∂y or fᵧ, represents the rate of change of f with respect to y while keeping x constant.

Let's calculate these partial derivatives:

fₓ = d/dx(2e^x - y) = 2e^x

fᵧ = d/dy(2e^x - y) = -1

Now, we have the partial derivatives evaluated at the point (x0, y0). Let's assume our point of interest is (a, b), where a = x0 and b = y0.

At the point (a, b), the equation for the tangent plane is given by:

z - f(a, b) = fₓ(a, b)(x - a) + fᵧ(a, b)(y - b)

Substituting fₓ(a, b) = 2e^a and fᵧ(a, b) = -1, we have:

z - f(a, b) = 2e^a(x - a) - (y - b)

Now, let's substitute f(a, b) = 2e^a - b:

z - (2e^a - b) = 2e^a(x - a) - (y - b)

Rearranging and simplifying:

z = 2e^a(x - a) - (y - b) + 2e^a - b

The final equation for the tangent plane to the graph of f at the point (a, b) is z = 2e^a(x - a) - y + 2e^a - 2b.

This equation represents the plane that is tangent to the graph of f at the specified point (a, b).

We will see that the first term is $50, and the common difference is $25, then the recursive formula is:

Here we will have something like an arithmetic sequence, such that the recursive sequence is something like:

aₙ = aₙ₋₁ + d

Where d is the common difference.

We know that the first value (the first amount that she has in her savings account) is $50, so we can write the first term as:

a₁ = $50

Now, each new year (the subindex "n" represents the number of the year)  $25 are added to that savings account, then we will have:

Answer:

119 is the value of x when y = 7

Step-by-step explanation:

Since y varies inversely with x, we can use the following equation to model this:

y = k/x, where

Step 1:  Find k by plugging in values:

Before we can find the value of x when y = k, we'll first need to find k, the constant of proportionality.  We can find k by plugging in 49 for y and 17 for x:

Plugging in the values in the inverse variation equation gives us:

49 = k/17

Solve for k by multiplying both sides by 17:

(49 = k / 17) * 17

833 = k

Thus, the constant of proportionality (k) is 833.

Step 2:  Find x when y = k by plugging in 7 for y and 833 for k in the inverse variation equation:

Plugging in the values in the inverse variation gives us:

7 = 833/x

Multiplying both sides by x gives us:

(7 = 833/x) * x

7x = 833

Dividing both sides by 7 gives us:

(7x = 833) / 7

x = 119

Thus, 119 is the value of x when y = 7.

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=71/9, 55/9

Step-by-step explanation:

We are given the absolute value equation 9|x-7| + 9 = 17, and we want to solve the equation for x.

First, we need to isolate the absolute value on one side of the equation.

To do this, we can first subtract 9 from both sides.

9|x-7| + 9 = 17
         -9     -9

____________________

9|x-7| = 8

Now, we divide both sides by 9.

|x-7| = 8/9

For absolute value equations, there are two cases; one case is when the expression (or number) that the absolute value expression is equal to is positive, and the other is when it is negative.

This means we need to split the equation into 2 cases.

The first case is when 8/9 (the number the absolute value expression is equal to) is positive.

x - 7 = 8/9

Add 7 to both sides.

x = 71/9

The second case is when 8/9 is negative.

x - 7 = -8/9

Add 7 to both sides.

x = 55/9

The solution is:

x = 71/9, 55/9
