Should be x/9

Step-by-step explanation:

The inverse of the function is F' ( x ) = x/9

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as F ( x )

Now , the value of F ( x ) is

F ( x ) = 9x  be equation (1)

Now , let the inverse of the function be represented as F' ( x )

where , the values of y are interchanged with x

So , the equation is

y = 9x

when x in interchanged ,

x = 9y

On solving for y , we get

Divide by 9 on both sides , we get

y = x / 9

So , the inverse of the function is F' ( x ) = x/9

Hence , the inverse of the function is F' ( x ) = x/9

Step-by-step explanation:

x is the number of days Kathleen's burritos stand use

3/8x = 1 1/8

x = (1 1/8)/(3/8) = (9/8)/(3/8) = (9/8)x(8/3) = 9/3 = 3

Answer:

= 9/3

= 3.

For the given scenario: the Probability of making both shots are A. 0.64 and B. 0.72

a) If a player makes 80% of his foul shots, the probability of making a single foul shot is 0.8. Since the two shots are considered independent events, the probability of making both shots is the product of the individual probabilities.

Therefore, the probability of making both shots is 0.8 * 0.8 = 0.64.

To calculate the probability of making exactly one shot, we need to consider two scenarios: making the first shot and missing the second, or missing the first shot and making the second. Each scenario has a probability of 0.8 * 0.2 = 0.16.

Therefore, the probability of making exactly one shot is 0.16 + 0.16 = 0.32.

Similarly, the probability of missing both shots is 0.2 * 0.2 = 0.04.

b) In this case, the outcome of the second shot depends on the outcome of the first shot. If the player makes the first shot (with a probability of 0.8), the probability of making the second shot is 0.9.

Therefore, the probability of making both shots is 0.8 * 0.9 = 0.72.

If the player misses the first shot (with a probability of 0.2), the probability of making the second shot is 0.7.

Therefore, the probability of making exactly one shot is 0.2 * 0.7 = 0.14.

Since there are only two possible outcomes (making both shots or making exactly one shot), the probability of neither shot being made is 1 - (0.72 + 0.14) = 0.14.

Therefore, for the given scenario:

a) Probability of making both shots: 0.64

  Probability of making exactly one shot: 0.32

  Probability of missing both shots: 0.04

b) Probability of making both shots: 0.72

  Probability of making exactly one shot: 0.14

  Probability of missing both shots: 0.14

Answer:

15.8 ft

Step-by-step explanation:

The inclined plane, the base of and the shelving unit form the shape of a right angled triangle.

The hypotenuse is the length of the inclined plane, h.

The base of the triangle is 15 ft.

The height of the triangle is 5 ft.

To find the hypotenuse, h, we have to use Pythagoras rule:

\(h^2 = a^2 + b^2\)

where a = height of the triangle

b = base of the triangle

Therefore:

\(h^2 = 5^2 + 15^2\\\\h^2 = 25 + 225 = 250\\\\h = \sqrt{250}\\ \\h = 15.8 ft\)

The inclined plane is 15.8 ft long.

Step-by-step explanation:

The distance between the points A ( 2 , -12 ) and B ( -11 , -12 ) is 13 units

What is the distance of a line between 2 points?

The distance of a line between 2 points is always positive and given by the formula

Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )

The distance between A and B is D , and the distance D is

\(Distance D = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }\)

Given data ,

Let the distance between the two points be = D

Let the first point be represented as = A

The value of A = A ( 2 , -12 )

The second point be represented as = B

The value of B = B ( -11 , -12 )

Now , the distance between the points A and B is given by the equation of distance formula

\(Distance D = \sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }\)

Substituting the values in the equation , we get

\(Distance D = \sqrt{(-12-(-12)^{2} + (2-(-11))^{2} }\)

On simplifying the equation , we get

\(Distance D = \sqrt{(0 + (2+11))^{2} }\)

\(Distance D = \sqrt{(13)^{2} }\)

\(Distance D = 13\)

Therefore , the value of D is 13

Hence ,

The distance between the points A ( 2 , -12 ) and B ( -11 , -12 ) is 13 units

The revenue function is:  R(x) = 750,000x + $5,000,000

To find the cost function C(x), we need to integrate the marginal cost of producing the xth box of DVDs.

∫(15+ dx) = 15x + C

We know that the fixed cost is $100,000, so when x = 0, the total cost is $100,000.

15(0) + C = $100,000

C = $100,000

Therefore, the cost function C(x) is:

C(x) = 15x + $100,000

To find the revenue function, we use the formula:

Revenue = Price x Quantity

Since the problem doesn't give us the price, we'll use the variable P for price.

We know that the revenue when x boxes of DVDs are produced is 50,000 times the cost C(x):

Revenue = 50,000C(x)

Substituting the cost function we just found, we get:

Revenue = 50,000(15x + $100,000)

Simplifying:

Revenue = 750,000x + $5,000,000

a. To show that the model can be written as xt = δt + ∑1twk, we can use induction.

For t = 1:

x1 = δ + x0 + w1

= δ + 0 + w1

= δ + w1

So the base case holds.

Assume that the model holds for t = k, i.e., xk = δk + ∑1k wk.

For t = k+1:

xk+1 = δ + xk + wk+1

= δ + (δk + ∑1k wk) + wk+1

= δk+1 + ∑1k+1 wk

Therefore, by induction, the model can be written as xt = δt + ∑1twk.

v. To find the mean function of xt, we can take the expected value of both sides of the model equation:

E[xt] = E[δt + ∑1twk]

= E[δt] + E[∑1twk]

= δt + ∑1tE[wk]

= δt

So, the mean function of xt is given by μt = δt.

To find the autocovariance function of xt, we need to calculate Cov(xt, xs) for s ≠ t.

For s < t:

Cov(xt, xs) = Cov(δt + ∑1twk, δs + ∑1swk)

= Cov(δt, δs) + Cov(δt, ∑1swk) + Cov(∑1twk, δs) + Cov(∑1twk, ∑1swk)

= 0 + 0 + 0 + Cov(∑1twk, ∑1swk)

= Cov(∑1twk, ∑1swk)

= Cov(wt + ∑1t-1wk, ws + ∑1s-1wk)

= Cov(wt, ws) + Cov(wt, ∑1s-1wk) + Cov(∑1t-1wk, ws) + Cov(∑1t-1wk, ∑1s-1wk)

= 0 + 0 + 0 + Cov(∑1t-1wk, ∑1s-1wk)

Since wt and wk are white noise with mean zero and variance σw^2, their covariance is zero unless t = s. Therefore, we have:

Cov(xt, xs) = 0 for s < t

For s > t, the covariance remains zero as well, since we can use the same logic as above.

For s = t, we have:

Cov(xt, xs) = Cov(δt + ∑1twk, δt + ∑1twk)

= Cov(δt, δt) + Cov(δt, ∑1twk) + Cov(∑1twk, δt) + Cov(∑1twk, ∑1twk)

= Var(δt) + Cov(∑1twk, ∑1twk)

= Var(δt) + Var(∑1twk) + 2Cov(∑1twk, ∑1twk)

= Var(δt) + Var(∑1twk) + 2∑1t-1Cov(wk, wk)

= Var(δt) + Var(∑1twk) + 2∑1t-1σw^2

Since δ is a constant and wk is a white noise process, Var(∑1twk) = ∑1tVar(wk) = tσw^2.

Therefore, we have:

Cov(xt, xs) = Var(δt) + tσw^2 + 2∑1t-1σw^2

= Var(δt) + tσw^2 + 2σw^2(t-1)

= Var(δt) + 3tσw^2 - 2σw^2

Finally, we can conclude that the mean function of xt is μt = δt, and the autocovariance function of xt is Cov(xt, xs) = Var(δt) + 3tσw^2 - 2σw^2.

c. To determine if xt is stationary, we need to check if the mean function and autocovariance function are independent of time (t).

In this case, the mean function is μt = δt, which is dependent on time. Therefore, xt is not stationary.

Similarly, the autocovariance function Cov(xt, xs) = Var(δt) + 3tσw^2 - 2σw^2 depends on both t and s, so xt is not stationary.

The difference in pay between Gianna and Samuel is $377.40. Samuel earned more than Gianna during their summer jobs.

During their summer jobs, Samuel earned a total of $634.40 in 26 hours of work. To find Samuel's hourly rate, we divide his total earnings by the number of hours worked: $634.40 / 26 hours = $24.40 per hour.

On the other hand, Gianna earned $256 in 10 hours, which means her hourly rate is $256 / 10 hours = $25.60 per hour. Similarly, Gianna earned $512 in 20 hours, resulting in an hourly rate of $512 / 20 hours = $25.60 per hour as well.

To calculate the difference in pay between the two friends, we subtract Samuel's total earnings from Gianna's total earnings: ($25.60 per hour x 10 hours) + ($25.60 per hour x 20 hours) - ($24.40 per hour x 26 hours) = $256 + $512 - $634.40 = $377.40. Therefore, the difference in pay between Gianna and Samuel is $377.40.

To evaluate the series Σ(3^n/(141·3²ⁿ) from n=1 to infinity converges or diverges, we can use the ratio test.

The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges absolutely;

if the limit is greater than 1, then the series diverges; and if the limit is exactly 1, then the test is inconclusive.

Let's first apply the ratio test to this series:

| (3ⁿ+¹/(141·3²ⁿ+¹) * (141·3²ⁿ))/(3ⁿ |

= | 3/141 |

= 1/47

Since the limit of the absolute value of the ratio of consecutive terms is less than 1, the series converges absolutely.

To compute the sum of the series, we can use the formula for the sum of a geometric series:

Σ(3ⁿ/(141·3²ⁿ) = 3/141 Σ(1/9)ⁿ from n=1 to infinity

= (3/141) · (1/(1-(1/9)))

= 27/470

Therefore, the series converges absolutely and its sum is 27/470.

What are algebraic expressions?

Algebraic expressions are sequences or combinations of characters containing letters, numbers, symbols, operators, and variables which are used to derive a certain relation among all of them.  

What is an algebraic equation?

When an algebraic expression has a value it becomes an algebraic equation. The algebraic equation helps to make a relation between different variables for a problem.

Let's solve the question.

2x - 12 = 2(x - 10) - 87

Adding 12 on both sides:

2x - 12 + 12 = 2(x-10) - 87 + 12

=> 2x = 2(x -10) - 75

=> 2x = 2x - 20 - 75

=> 2x = 2x - 95

Adding -2x on both sides:

2x - 2x = 2x - 95 - 2x

0 = -95

This is contradictory.

The equation is independent of x, and 0 = -95 is false. Therefore, the equation has no solutions.

Hence the equation 2x - 12 = 2(x-10)-87 has no solutions.
