Step-by-step explanation:

The value of the trigonometric expression sin(S) and sin(T) will be 5 / 13 and 12 / 13, respectively. Then the correct option is B.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

sin (S) = TR / ST

sin (S) = 5 / 13

sin (T) = RS / ST

sin (T) = 12 / 13

The value of the trigonometric expression sin(S) and sin(T) will be 5 / 13 and 12 / 13, respectively. Then the correct option is B.

Answer:

35° and 55°

Step-by-step explanation:

Complementary angles sum to 90°

let one angle be x and the other x + 20 , then

x + x + 20 = 90

2x + 20 = 90 ( subtract 20 from both sides )

2x = 70 ( divide both sides by 2 )

x = 35°°

x + 20 = 35 + 20 = 55

The expected number of companies that might not respond is 67.5.

Based on the given information, we can model the nonresponse rate using a binomial distribution. Let's define the following variables:

n = Number of questionnaires mailed = 150

p = Probability of not responding = 0.45

To determine the number of companies that might not respond, we can calculate the probability of different scenarios using the binomial distribution formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

Where:

X represents the number of companies that do not respond.

k represents the number of companies that do not respond.

C(n, k) is the binomial coefficient, calculated as C(n, k) = n! / (k! * (n - k)!)

To find the probability of a specific number of companies not responding, we substitute the values of n, p, and k into the formula.

For example, to find the probability that exactly 70 companies do not respond, we can calculate:

P(X = 70) = C(150, 70) * 0.45^70 * (1 - 0.45)^(150 - 70)

To find the expected number of nonresponses, we can use the formula:

E(X) = n * p

In this case:

E(X) = 150 * 0.45

So the expected number of companies that might not respond is 67.5.

Note: The binomial distribution assumes independent and identically distributed trials, so it is important to ensure that the assumption holds in the given scenario.

The logarithm of 0.79 is approximately -0.1 when rounded to the nearest tenth. Since the answer is less than 1, we need to include a leading 0. Therefore, the final answer is -0.1, rounded to the nearest tenth.

The logarithm of 0.79 is approximately -0.1046 when calculated more precisely. However, when rounded to the nearest tenth, the result becomes -0.1. In logarithmic notation, the leading zero is necessary to indicate that the value is between 0 and 1.

Logarithms are a way to express the exponent to which a base must be raised to obtain a given number. In this case, we are finding the logarithm of 0.79 to the base 10. Since 0.79 is a decimal less than 1, the logarithm will be negative. Rounding the result to the nearest tenth gives us -0.1.

It's important to note that logarithms are mathematical tools used in various fields, such as science, engineering, and finance, to simplify calculations and analyze data. The rounded value of -0.1 represents an approximation of the logarithm of 0.79, which can be useful in practical applications where a more precise value is not necessary.

In a cubic polynomial function f is defined by f(x) = 4x³ + ax² + bx + k, where a, b, k, are constants and has a local minimum at x = -2 and a local maximum at x = 0, then values of a and b is 12 and 0 respectively. If integrate of f(x)dx = 32 from 0 to 1, then value of k is 27.

The given cubic polynomial function is

f(x) = 4x³ + ax² + bx + k

f'(x) = 12x² + 2ax + b

f''(x) = 24x + 2a

At local maximum f' = 0

f'(0) = 12×(0)² + 2a×(0) + b = 0

b = 0

At local minimum, f' = 0

That is f'(-2) = 0 and f''(-2) > 0

f'(-2) = 12×(-2)² + 2a×(-2) + b = 0

48 - 4a + b = 0

4a - b = 48  

a = 12

Therefore, f(x) =  4x³ + 12x² + k

Integrate f(x)dx = 32 from 0 to 1, that is

∫₀¹ f(x)dx = 32

∫₀¹ (4x³ + 12x² + k) dx = 32

[ x⁴ + 4x³ + kx ]₀¹ = 32

(1⁴ - 0⁴) + 4(1³ - 0³) + k(1 - 0) = 32

a. The unemployment rate is 20%.

b. The labor-force participation rate is 60%.

According to the question,

Working age population- 100,000

Labour force - 60,000

Unemployed - 12000 instructions

a) The unemployment rate is the percentage of the labor force that is unemployed and it is calculated as follows:

Unemployment Rate = \(\frac{Number of unemployed People}{Labor force}\) × 100

When an unemployed population is 12,000 and the labor force is 60,000,

the unemployment rate is  = \(\frac{12000}{60000}\) × 100 = 20%

b) labor force participation rate is the percentage of working adult population that participates in labor either by actively looking for a job, or working. It is calculated as follows:

Labor Force Participation Rate = \(\frac{Labor force}{working age population}\) × 100

When the labor force is 60,000 and the working-age population is 100,000

Labor Force Participation Rate = \(\frac{60000}{100000}\) × 100 = 60%

So, a. The unemployment rate is 20%.

The requried Burger Quick is able to estimate its wait time more consistently because it has a smaller IQR. Option A is correct.

A straightforward method of expressing statistical data on a plot in which a rectangle is drawn to represent the second and third quartiles, with a vertical line inside to indicate the median value.

Here,
Burger Quick is able to estimate its wait time more consistently because it has a smaller interquartile range (IQR). The IQR is a measure of the spread of the middle 50% of the data and is calculated as the difference between the third quartile (Q3) and the first quartile (Q1). The smaller the IQR, the more consistent the data is around the median, which is represented by the line within the box in the box plot.

In this case, Burger Quick has a smaller IQR (8.0) compared to Super Fast Food (7.0), indicating that the wait times at Burger Quick are more consistent around the median. The range, which is the difference between the maximum and minimum values, is not a good measure of consistency as it is affected by outliers.

The series ∑(−1)^(n+1) (ln(n)/(n+1)) diverges.

We can use the integral test to determine whether the series converges or diverges. The integral test states that if f(x) is a positive, continuous, and decreasing function for x ≥ N and if the terms of the series a_n are also positive, then the series ∑a_n and the integral ∫N^∞ f(x) dx either both converge or both diverge.

Let's apply the integral test to the series ∑(−1)^(n+1) (ln(n)/(n+1)):

f(x) = ln(x)/(x+1)

f'(x) = (1-ln(x))/(x+1)^2

Since f'(x) is negative for x ≥ 3, f(x) is decreasing for x ≥ 3. Therefore, we can use the integral test with N = 3:

∫3^∞ ln(x)/(x+1) dx = [ln(x)^2/2]_3^∞ = ∞

Since the integral diverges, the series ∑(−1)^(n+1) (ln(n)/(n+1)) also diverges by the integral test.

Therefore, the series ∑(−1)^(n+1) (ln(n)/(n+1)) diverges.

By applying the maximum modulus principle, we found that the maximum value of 2i(z²) + 3 on the set of complex numbers whose modulus is less than or equal to 1 is √13.

Let's start by expressing the given function in terms of z. We have:

f(z) = 2i(z²) + 3

Now, let's consider the modulus of f(z):

|f(z)| = |2i(z²) + 3|

According to the maximum modulus principle, the maximum value of |f(z)| occurs on the boundary of the given domain, which is the circle of radius 1 centered at the origin in the complex plane.

In order to find the maximum value, we need to evaluate |f(z)| on the boundary of the circle |z| = 1.

Let's substitute z = 1 into f(z):

f(1) = 2i(1²) + 3

= 2i + 3

Taking the modulus of f(1):

|f(1)| = |2i + 3|

To find the maximum value, we need to determine the magnitude of the complex number 2i + 3. The modulus (or magnitude) of a complex number a + bi, denoted as |a + bi|, is given by:

|a + bi| = √(a² + b²)

For the complex number 2i + 3, we have:

|2i + 3| = √(2² + 3²)

= √(4 + 9)

= √13

Therefore, the maximum value of |f(z)| occurs at |z| = 1 and is equal to √13.

Answer:

x=-4, y=-1

Step-by-step explanation:

Given the following system of equations, solve the system using elimination.

\(\left \{ {{-2x-y=9} \atop {2x-9y=1}} \right.\)

(1) - Add the equations together

\(\left\begin{array}{ccc}&-2x-y=9\\+&2x-9y=1\end{array}\right\\\\\Longrightarrow -10y=10\\\\\therefore \boxed{y=-1}\)

Notice how the x term was eliminated, hence the name for this method is "elimination."

(2) - Take the value we just found for y and plug it into either of the two equations and solve for x

\(2x-9y=1\\\\\Longrightarrow 2x-9(-1)=1\\\\\Longrightarrow 2x+9=1\\\\\Longrightarrow 2x=-8\\\\\therefore \boxed{x=-4}\)

(3) - Thus, the system is solved. When x=-4, y=-1.
