Below

Step-by-step explanation:

Domain    'x' can be any value except 10 <====which would make the denominator = 0 which is not allowed

   (-∞, 10 )  U (10 , +∞)

Range :   horizontal asymptote    the degree of the numerator and the denominator is the same : 1     so the horizontal asymptote will be

          3 / -1 = -3    ( The coefficients of 'x' in the num and den)

   the vertical asymptote occurs at x = 10 ...then the value of y goes to + inf

        so range is   ( -3, +∞)

Inverse Does exist , switch x's and y's in the original equation

   x = (3y+1) / (10-y)     now solve for   y

     and you will get  f^-1 (x) = (10x-4) / (x+3)

The p-value is 0.1138 for the given hypothesis.

What exactly is a p-value?

A p-value, or probability value, is a statistical measure that helps to determine the strength of evidence against a null hypothesis in a hypothesis test. In hypothesis testing, a null hypothesis is a statement or assumption about a population parameter that we want to test using sample data. The p-value is the probability of obtaining a test statistic as extreme as, or more extreme than, the observed test statistic, assuming the null hypothesis is true.

Now,

To test the hypothesis,

 we need to perform a hypothesis test using a significance level (α) to determine whether the sample proportion of satisfied customers is significantly different from 0.9.

The null hypothesis (H0) is that the true proportion of satisfied customers is equal to 0.9. The alternative hypothesis (H1) is that the true proportion is not equal to 0.9.

We can use the normal approximation to the binomial distribution to test this hypothesis, since the sample size is large (n = 1000) and both np and n(1-p) are greater than or equal to 10, where p is the true proportion of satisfied customers.

The test statistic is given by:

z = (P - p0) / √(p0(1 - p0) / n)

where p0 is the proportion (0.9), P is the sample proportion (850/1000 = 0.85), and n is the sample size.

Plugging in the values, we get:

z = (0.85 - 0.9) / √(0.9 * 0.1 / 1000) = -1.5811

The P-value is the probability of getting a test statistic as extreme as -1.5811 or more extreme, assuming the null hypothesis is true. Since this is a two-tailed test (H1: p ≠ 0.9), we need to find the area in both tails of the standard normal distribution.

Using a standard normal distribution table, we find that the area to the left of -1.5811 is 0.0569, and the area to the right of 1.5811 is also 0.0569. Therefore, the total area in both tails is:

p-value = 0.0569 + 0.0569 = 0.1138

So,

     the p-value is 0.1138.

What is Trigonometric Functions?

Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.

y=tanx

dy/dx = dy/dx = cos x.cos x - sin x(-sin x) / cos² x

⇒ dy/dx = (cos² x + sin² x) / cos² x

⇒ dy/dx = 1 / cos²x

⇒ dy/dx = sec²(x)

The value of f(15) is approximately 346.42.

An exponential function is a mathematical function of the form f(x) = abˣ, where a and b are constant and b is greater than zero and not equal to 1. An example is f(x) = 2ˣ

We can use the properties of exponential functions to find the value of f(15). Since f(x) is an exponential function, we can write it in the form:

f(x) = a × bˣ

f(4.5) = 16 = a × b⁴.5

f(9.5) = 60 = a × b⁹.5

Dividing second equation by first equation gives:

f(9.5)/f(4.5) = (a × b⁹.5)/(a × b⁴.5) = b⁵

Substituting the given values, we get:

60/16 = b⁵

b = (60/16)¹/⁵

b ≈ 1.46

Substituting b into the first equation gives:

16 = a × 1.46⁴.5

a ≈ 0.30

Therefore, the exponential function is:

f(x) = 0.30 × 1.46ˣ

To find f(15), we can substitute x = 15 into the function:

f(15) = 0.30 × 1.46¹⁵

f(15) ≈ 346.42

The possible value of x that is here, a are 8 and 12, when the sum of two number and product is given.

A group of two or more equations that must be solved all at once is known as a system of equations. The values of the variables in a system of equations that make all of the equations in the system true are known as the solutions. Several approaches, including substitution, elimination, and graphing, can be used to solve systems of equations. Several branches of mathematics, science, and engineering employ systems of equations to represent and solve issues that arise in the real world.

Let us suppose the two numbers = a and b.

Thus, from the given statement we have:

a + 2b = 20 (Equation 1)

and

ab ≤ 48 (Equation 2)

Using equation 1:

a = 20 - 2b

Substituting this expression for "a" into Equation 2, we get:

(20 - 2b)(b) ≤ 48

-2b² + 20b - 48 ≤ 0

b² - 10b + 24 ≥ 0

This inequality can be factored as:

(b - 4)(b - 6) ≥ 0

Since we want the product of the two numbers to be less than or equal to 48, both "a" and "b" must be positive.

We only need to consider the values of "b" that make this inequality true:

b ≤ 4 or b ≥ 6

Plug each of these values of "b" back into Equation 1:

When b = 4, we get:

a + 2(4) = 20

a = 12

When b = 6, we get:

a + 2(6) = 20

a = 8

Therefore, the possible values of "a" are 8 and 12.

We can say that after answering the offered question The ladder is Pythagorean theorem therefore 15 feet long, rounded up to the next foot. Thus, 15 feet is the solution.

The Pythagorean Theorem is the foundational Euclidean geometry connection that exists between the three sides of the right triangle. According to this rule, the area of either a cube with the length x side is equal to the total of the regions of triangles shared by its other two sides. According to the Pythagorean Theorem, the square that spans the hypotenuse of a right triangle opposite the perfect angle is the combined squares that spanned its sides. It is sometimes expressed as a2 + b2 = c2 in general algebraic notation.

The ladder serves as the hypotenuse in this basic example of a right triangle, which also includes the distance from the house as one of its legs and the ladder's height as its second leg. The Pythagorean theorem can be used to find the ladder's length.

[tex]c^2 = a^2 + b^2[/tex]

In this instance, we know that the distance from the house (a) is 9 feet, and the height of the ladder (b) is 12 feet. Hence, we can enter these values into the formula as follows:

[tex]c^2 = 9^2 + 12^2 c^2 = 81 + 144\sc^2 = 225\sc = √225\sc = 15[/tex]

Answer: The probability that both grab oranges would be =1/36

Step-by-step explanation:

Given,

A bowl contains,

Apples = a = 5

Oranges = o = 2

bananas = b = 2

Total fruits in bowl = x = a + o + b = 5 + 2 + 2 = 9

Now, Christian and Aaron come home from school and randomly grab one fruit each.

The probability of first selecting orange would be = o/b =2/9

Now, the oranges left would be 2 - 1 = 1

and total fruits would be = 9 - 1 = 8

Hence, the probability of selecting second orange would be = 1/8

Therefore, the probability that both grab oranges would be = 1/8 2/9 =1/36

Step-by-step explanation:

The number of weeks until Riley and Amari would have earned the same, would be 10 weeks.

Variables:

Let x be the number of weeks they work.

Let y be their total earnings in dollars.

System of equations:

For Riley: y = 5x

For Amari: y = 20 + 3x

Setting the two expressions for y equal to each other, we get:

5x = 20 + 3x

5x - 3 x = 20

x = 20 / 2

x = 10 weeks

Therefore, their earnings will be the same after 10 weeks of work.

Using the Law of Cosines the length of l, to the nearest 10th of a centimeter is 4.6 cm.

To find the length of side l in triangle LMN, we can use the Law of Cosines, which states that c² = a² + b² - 2ab cos(C), where c is the side opposite the angle C.

In this case, we have:

a = 5.9 cm

b = 8.7 cm

C = 163°

First, we need to convert the angle from degrees to radians by multiplying it by π/180:

C = 163° × π/180 = 2.847 radians

Now we can plug in the values into the Law of Cosines:

l² = 5.9² + 8.7² - 2(5.9)(8.7)cos(2.847)

Simplifying the right-hand side:

l² = 68.81 - 60.83 × cos(2.847)

Taking the square root of both sides:

l ≈ 4.6 cm

Therefore, the length of l to the nearest 10th of a centimeter is 4.6 cm.

Using a calculator or statistical software, we get:

Slope (b) = 0.621

Y-intercept (a) = 50.4

Therefore, the linear regression equation is:

y = 0.6x + 50.4

To find the projected test grade for a student with a homework grade of 45, we substitute x = 45 into the equation:

y = 0.6(45) + 50.4

y = 27 + 50.4

Answer: Let's call the number of large boxes purchased "L" and the number of small boxes purchased "S".

From the problem, we know that:

Each small box has 100 nails, so the total number of nails from the small boxes is 100S.

Each large box has 450 nails, so the total number of nails from the large boxes is 450L.

The contractor bought 3 more small boxes than large boxes, so S = L + 3.

The total number of nails purchased is 2500, so 100S + 450L = 2500.

We can use the second equation to solve for one of the variables in terms of the other. For example, we can solve for L:

100S + 450L = 2500

Substituting S = L + 3:

100(L + 3) + 450L = 2500

Expanding the parentheses:

100L + 300 + 450L = 2500

Combining like terms:

550L + 300 = 2500

Subtracting 300 from both sides:

550L = 2200

Dividing both sides by 550:

L = 4

So the contractor purchased 4 large boxes of nails.

We can use the equation S = L + 3 to find the number of small boxes purchased:

S = L + 3 = 4 + 3 = 7

So the contractor purchased 7 small boxes of nails.

Therefore, the contractor purchased 4 large boxes and 7 small boxes of nails.

What is area and volume?

A flat, two-dimensional object's area is the space it takes up in a plane. A three-dimensional object's volume is the area it takes up in space.

We know that

Curved surface area = 2πrh

So, using this we get

⇒Curved surface area = 2 × 3.14 × 14 ×25

⇒Curved surface area = 2,198 square centimeter

Similarly,

Total surface area = 2πr (r + h)

So, using this we get

⇒Total surface area = 2 × 3.14 × 14 (14 + 25)

⇒Total surface area = 2 × 3.14 × 14 (39)

⇒Total surface area = 3,428 square centimeter

Similarly,

Volume = π[tex]r^{2} h[/tex]

So, using this we get

⇒Volume = 3.14 × [tex]14^{2}[/tex] × 25
