How should an interval equation be written?

Intervals are expressed using parentheses or rectangular brackets, and a comma is used to separate two integers. The two numbers are referred to as the interval's endpoints. The least element or lower bound is shown by the number on the left. The biggest element or upper bound is shown by the number on the right.

As a result, when x = 4 and 5 4, f (x) has its maximum value of 1, which is 1.

A range of numbers between two specified numbers that include all real numbers in that range is known as an interval.

P(A)=0.60, p(b)=0..25 and p(A and B)=.15 what is p(A or B)?

Answers

Answer:

  0.70

Step-by-step explanation:

You want p(A+B) given that p(A) = 0.60, p(B) = 0.25, and p(A·B) = 0.15.

Probability

The relevant formula is ...

  p(A+B) = p(A) +p(B) -p(A·B)

  p(A+B) = 0.60 +0.25 -0.15

  p(A+B) = 0.70

__

Additional comment

In the attached Venn diagram, the sum of the numbers inside the circle labeled A is p(A) = 0.45 +0.15 = 0.60. Likewise, the sum of the numbers inside circle B is p(B) = 0.15 +0.10 = 0.25.

As the attachment shows, the event A includes the event 'A and B'. Likewise, event B includes the event 'A and B'. Simply adding the probabilities of A and B will cause p(A and B) to be counted twice.

Use the following equation to derive a demand schedule and a demand curve. What types of products might exhibit this type of nonlinear demand curve?

Answers

The equation is as follows: Q = a - bP^2.Nonlinear demand curve like this can be found in luxury goods and Veblen goods. Where the luxury goods are the goods whose demand increases as the price increases and Veblen goods are the goods whose demand increases with an increase in the consumer's income.

The equation is as follows: Q = a - bP^2.

To derive a demand schedule, we can plug in different values of P (price) and solve for Q (quantity demanded). For example:

Q = a - bP^2

Q = a - (b * 10^2)

Q = a - 1000b

Q = a - (b * 9^2)

Q = a - 810b

Q = a - (b * 8^2)

Q = a - 640b

and so on.

To derive a demand curve, we can plot the different points from the demand schedule on a graph, with P on the x-axis and Q on the y-axis. The demand curve will be a downward-sloping parabola.

Aiden asked a group of students to choose their favorite type of music from the choices of rock, hip-hop, and country. The results of the survey are shown in the graph.

Based on the graph, how many students in a class of 360 students would be expected to choose hip-hop or rock as their favorite type of music?

Answers

Number of students who are expected to choose hip hop or rock as their favorite type of music is 240.

What is Percentage?

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

So the percentage actually means a part per 100.

Percentage is usually denoted by the symbol '%'.

From the graph,

Number of students who choose rock music = 20

Number of students who choose hip hop music = 40

Number of students who choose country music = 30

Total number of students = 20 + 40 + 30 = 90

Percentage of students who choose rock or hip hop = (20+ 40) / 90

                                                                                        = (60 / 90)

                                                                                        = 66.67%

Out of 360 students, 66.67% of students will chose hip hop or rock.

360 × (60/90) = 240

Hence 240 students choose either hip hop or rock as their favorite music.

The number of papers ms. Motley grades increases exponentially as

How many will she grade in five days?

After many days will it take her to grade 6,000 papers?

Answers

The papers graded exponentially at the end of 5 days are 134, and it will take approximately around 12 days to complete 6000 papers.

What is exponential function?

A function is considered to be exponentially growing if its value rises faster than any polynomial. The function e^x, serves as a good illustration.

The exponential growth is given by the following formula:

[tex]A = Pe^{rt}[/tex]

where, A is the final amount, P is the initial amount, r is the rate and t is the time.

For t = 0, the number of papers graded are, 9, hence the value of P = 9.

To calculate the rate at which the work is done, substitute the value of P = 9, A = 27 and t = 2 in the equation:

[tex]27 = 9 e^{2r}\\3 = e^{2r}[/tex]

Taking ln on both sides of the equation:

[tex]ln (3) = ln(e^{2r})\\\\ln(3) = 2r[/tex]

1.09 = 2r

r = 0.54

To calculate the number of papers graded in five days, substitute the value of P = 9, t = 5 and r = 0.54.

[tex]A = 9 e^{(0.54)(5)}[/tex]

A = 134

Hence, the papers graded at the end of 5 days are 134.

To complete grading 6000 papers, the time taken will be:

6000 = 9e^(0.54)(t)

666.66 = e^(0.54)(t)

Taking ln on both sides of the equation:

ln (666.66) = ln(e^(0.54)(t))

6.50 = (0.54)(t)

t = 12.04

Hence, it will take approximately around 12 days to complete 6000 papers.

In how may years ₹ 4,000 will amount to ₹ 14,400 at 10% p.a. Compounded interest payable quarterly ?

Answers

Answer:

P = ₹4,000

F = ₹14,400

r = 10% = 0.10

m = 4 (because interest is compounded quarterly)

So, we can plug in these values into the formula:

n = (log(14400 / 4000)) / (log(1 + 0.10 / 4))

n = (log(3.6)) / (log(1.025))

n = 2.59

Therefore, it will take approximately 2.59 years for the investment of ₹4,000 to grow to ₹14,400 at a 10% annual interest rate compounded quarterly.

The x-intercepts are the points at which the curve crosses the x-axis, so when y = 0.The y-intercept is the points at which the curve crosses the y-axis, so when x = 0.The domain of a function is the set of all possible input values (x-values).The range of a function is the set of all possible output values (y-values).A vertical asymptote occurs at the x-value(s) that make the denominator of a rational function zero.A horizontal asymptote occurs at y = 0 if the degree of the numerator is less than the degree of the denominator.A hole occurs when a rational function has a factor with an x that is in both the numerator and the denominator.

Question 33

Given rational function:

[tex]g(x) =\dfrac{x - 2}{x^2 - 2x - 3}[/tex]

x-intercept

[tex]\begin{aligned}y=0 \implies \dfrac{x - 2}{x^2 - 2x - 3}&=0\\x - 2&=0\\x&=2\end{aligned}[/tex]

y-intercept

[tex]x=0 \implies \dfrac{0 - 2}{0^2 - 2(0) - 3}=\dfrac{2}{3}[/tex]

Vertical asymptotes

Set the denominator to zero and solve for x:

[tex]\implies x^2-2x-3=0[/tex]

[tex]\implies x^2-3x+x-3=0[/tex]

[tex]\implies x(x-3)+1(x-3)=0[/tex]

[tex]\implies (x+1)(x-3)=0[/tex]

[tex]\implies x+1=0 \implies x=-1[/tex]

[tex]\implies x-3=0 \implies x=3[/tex]

Horizontal asymptote

As the degree of the numerator is less than the degree of the denominator, there is a horizontal asymptote at y = 0.  

Holes

Factor the denominator:

[tex]g(x) =\dfrac{x - 2}{(x+1)(x-3)}[/tex]

There are no holes as there is no common factor in the numerator and the denominator.

End behaviour near the vertical asymptotes

f(x) → -∞, as x → -1⁻

f(x) → +∞, as x → -1⁺

f(x) → -∞, as x → 3⁻

f(x) → +∞, as x → 3⁺

Domain

As there are vertical asymptotes at x = -1 and x = 3, the domain is restricted:

Interval notation:  (-∞, -1) ∪ (-1, 3) ∪ (3, ∞)

Range

The range is unrestricted:

Interval notation:  (-∞, ∞)

Question 34

Given rational function:

[tex]k(x)= \dfrac{x^2 - x - 2}{x - 3}[/tex]

x-intercepts

[tex]\begin{aligned}y=0 \implies \dfrac{x^2 - x - 2}{x - 3}&=0\\x^2 - x - 2&=0\\x^2-2x+x-2&=0\\x(x-2)+1(x-2)&=0\\(x+1)(x-2)&=0\\\\x+1&=0 \implies x=-1\\x-2&=0 \implies x=2\end{aligned}[/tex]

y-intercept

[tex]x=0 \implies \dfrac{(0)^2 - 0 - 2}{0 - 3}=\dfrac{2}{3}[/tex]

Vertical asymptotes

Set the denominator to zero and solve for x:

[tex]\implies x-3=0[/tex]

[tex]\implies x=3[/tex]

Holes

Factor the numerator:

[tex]k(x)= \dfrac{(x+1)(x-2)}{x - 3}[/tex]

There are no holes as there is no common factor in the numerator and the denominator.

End behaviour near the vertical asymptote

f(x) → -∞, as x → 3⁻

f(x) → +∞, as x → 3⁺

Domain

As there is vertical asymptote at x = 3, the domain is rest:

Interval notation:  (-∞, 3) ∪ (3, ∞)

Range

The extreme points are (1, 1) and (5, 9).  Therefore, the range is restricted:

Interval notation:  (-∞, 1] ∪ [9, ∞)

Question 35

Given rational function:

[tex]f(x)= -\dfrac{x}{x^3 - 4x}[/tex]

x-intercepts

As the degree of the numerator is less than the degree of the denominator, there is a horizontal asymptote at y = 0.  Therefore, there are no x-intercepts.

y-intercept

Substitute x = 0 and solve for y:

[tex]x=0 \implies -\dfrac{0}{0(x+2)(x-2)}=\dfrac{0}{0}=\textsf{unde\:\!fined}[/tex]

Therefore, there is no y-intercept.

Factor the denominator:

[tex]f(x)= -\dfrac{x}{x(x+2)(x-2)}[/tex]

Cancel the common factor x:

[tex]f(x)= -\dfrac{1}{(x+2)(x-2)}[/tex]

Vertical asymptotes

Set the denominator to zero and solve for x:

[tex]\implies (x+2)(x-2)=0[/tex]

[tex]\implies x+2=0 \implies x=-2[/tex]

[tex]\implies x-2=0 \implies x=2[/tex]

Holes

Factor the denominator:

[tex]f(x)= -\dfrac{x}{x(x+2)(x-2)}[/tex]

As the numerator and denominator have a common factor of x, the function is not defined when x = 0. Therefore, there is a hole when x = 0.

To find the y-value of the hole, cancel the common factor x and input x = 0 into the resulting function:

[tex]x=0 \implies -\dfrac{1}{(0+2)(0-2)}=\dfrac{1}{4}[/tex]

Therefore, there is a hole at (0, ¹/₄).

End behaviour near the vertical asymptotes

f(x) → -∞, as x → -2⁻

f(x) → +∞, as x → -2⁺

f(x) → +∞, as x → 2⁻

f(x) → -∞, as x → 2⁺

Domain

As there are vertical asymptotes at x = -2 and x = 2, and a hole at (0, ¹/₄), the domain is restricted:

Interval notation:  (-∞, -2) ∪ (-2, 0) ∪ (0, 2) ∪ (2, ∞)

Range

As there is a hole at (0, ¹/₄) and a horizontal asymptote at y = 0, the range is restricted:

Interval notation:  (-∞, 0) ∪ (¹/₄, ∞)

The quartic function y = 0.5 · x⁴ - x³ - 15.5 · x² + 30 · x + 21 contains roots 4 - √2 and - 3 + √6 and intercept - 21.

How to derive a quartic function

Quartic functions are polynomials of grade 4, whose factor form is introduced below:

y = a · (x - r₁) · (x - r₂) · (x - r₃) · (x - r₄)

Where:

a - Lead coefficientr₁, r₂, r₃, r₄ - Roots

According to statement, the quartic equation has an intercept of - 21 and two real roots: 4 - √2, - 3 + √6. The two remaining roots can be found based on features exhibited by quadratic formula and that quartic functions are the product of two quadratic functions: 4 + √2, - 3 - √6

Now we proceed to expand the quartic function:

y = a · (x - 4 + √2) · (x - 4 - √2) · (x + 3 - √6) · (x + 3 + √6)

y = a · (x² - 8 · x + 14) · (x² + 6 · x + 3)

y = a · [x² · (x² - 8 · x + 14) + 6 · x · (x² - 8 · x + 14) + 3 · (x² - 8 · x + 14)]

y = a · (x⁴ - 8 · x³ + 14 · x² + 6 · x³ - 48 · x² + 84 · x + 3 · x² - 24 · x + 42)

y = a · (x⁴ - 2 · x³ - 31 · x² + 60 · x + 42)

And we find the lead coefficient:

- 21 = 42 · a

a = - 0.5

And we obtain the quartic function in standard form:

y = 0.5 · x⁴ - x³ - 15.5 · x² + 30 · x + 21

Question 6
Find the area of triangle ABC:
AD is 1cm and BC is 1cm and D is 90

Answers

The area of triangle ABC is 0.5cm² where base and height are given.

Describe Area.

Triangle area is used to measure the size of a region on a surface. The area of a form or planar lamina is referred to as the plane region or plane area, as opposed to surface area, which denotes the area of an open surface or the boundary of a three-dimensional object.

The area of a triangle can be compared to the volume of material at a specific thickness needed to make a model of the form or the amount of paint needed to cover a surface in a single coat. It is equivalent to a solid's volume or a curve's length in two dimensions (a three-dimensional concept).

From the given figure, we can say that

Height = AD = 1cm

Base = BC = 1cm

Area of Triangle = Base × Height/2

Area = 1 × 1 /2

Area = 0.5 cm²

Answers

The situation that can be described as dependent events is c.) Renata randomly chooses a chocolate chip cookie from a cookie jar. She eats the cookie and chooses again. This time she gets a sugar cookie.

What are dependent events ?

Events that are dependent upon prior events are called dependent events. The results of earlier events have an impact on these current ones. For example, two or more occurrences that are interdependent are referred to as dependent events. An event generally qualifies as being reliant if it offers details about another event. If an event provides no information about other events, it is considered independent.

The dependent event would be Renata picking a sugar cookie the second time she chooses another cookie because she ate from the first cookie and so was able to avoid it the second time.

What is trigonometry?

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that at a given point of 67.7ft at the ground level of a covered court, the angle of elevation of a roof worker from the bottom is 38.6⁰ and the angle of elevation of the roof from the top is 42.4 degrees.

The base will be calculated as:-

tan(38.6) = P / B

tan(38.6) = 67.7 / B

B = 67.7 / tan(38.6)

B = 54.8 ft

The height will be calculated as:-

Cos(42.4) = B / H

H = 84.8 / Cos(42.4)

H = 114.83 ft

Therefore, If someone were to look down from above, they would be 114.83 feet from the object and 84.8 feet away.

FILL IN THE BLANK when calculating the confidence interval for the mean using a sample size of 30 or greater with a known population standard deviation, the ____ is used

Answers

The standard normal distribution is used when calculating the confidence interval for the mean using a sample size of 30 or greater with a known population standard deviation.

The Z-distribution (also known as the standard normal distribution) is a normal distribution with a mean of 0 and a standard deviation of 1. When the population standard deviation is known, the sample mean follows a normal distribution and the standard error is given by the population standard deviation divided by the square root of the sample size. So, the Z-score is given by (x - μ) / (σ / √(n)) where x is the sample mean, μ is the population mean and σ is the population standard deviation and n is the sample size.

With a sample size of 30 or greater, the central limit theorem states that the sample mean will be approximately normally distributed, regardless of the shape of the population distribution. So, a Z-score can be used to find the probability that a sample mean falls within a certain range of the population mean, which is commonly used to construct a confidence interval.

Answers

The circumference of the outer circle, greater, 12.57 feet, than the circumference of the inner​ circle.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

And the general formula of the circle,

(x – h)²+ (y - k)² = r²,

where (h, k) is the center and r is the radius of the circle.

Given:

The circumference of the inner circle is 64 feet.

The radius of the inner circle,

2πr = 64

r = 32 x 7/22

r = 112/11 feet.

The distance between the inner circle and the outer circle is 2 ft.

The radius of the outer circle,

= 112/11 + 2

= 134/11 feet.

The circumference of the outer circle,

= 2 x 22/7 x 134/11

= 76.57 feet.

Now, 76.57 - 64 = 12.57 feet.

Therefore, the circumference of the outer circle is greater than 12.57 feet.

what is the correct ordering, from smallest to largest, of the following: $\dfrac{7}{6},$ $\dfrac{17}{15},$ $\dfrac{28}{25}\,?$

Answers

So, the correct ordering from smallest to largest is 17/15, 7/6, 28/25.

When comparing fractions, one way to determine which fraction is larger or smaller is by finding a common denominator and then comparing the numerators. A common denominator is a multiple of both denominators. The least common denominator (LCD) is the smallest common denominator.

In this case, the least common denominator for the fractions 7/6, 17/15, 28/25 is 30.

This is because 30 is the smallest multiple of 6 and 15 that is also a multiple of 25

So, 7/6 = 35/30, 17/15 = 17/15 and 28/25 = 84/75

The numerators of the fractions are 35, 17, and 84 respectively. Since 17 is the smallest numerator and 84 is the largest numerator, we can conclude that 17/15 is the smallest fraction and 84/75 is the largest fraction.

Therefore, the correct ordering from smallest to largest is 17/15, 7/6, 28/25.

In summary, to compare fractions, we can find a common denominator, then compare the numerators. In this case, we used the least common denominator 30, and then compared the numerators 35, 17, 84, which allowed us to order the fractions in an increasing order.
