The producer's surplus for the supply function \(S(x) = x^2 + 1\) at x = 1 is 2 units.

To calculate the producer's surplus, we need to find the area between the supply curve and the price level at the given quantity.

At x = 1, the supply function \(S(x) = (1)^2 + 1 = 2\). Therefore, the price level corresponding to x = 1 is also 2.

To find the producer's surplus, we integrate the supply function from 0 to the given quantity (in this case, from 0 to 1) and subtract the area below the price level curve.

Mathematically, the producer's surplus (PS) is calculated as follows:

PS = ∫[0, x] S(t) dt - P * x

Substituting the values, we have:

PS = ∫[0, 1] (t^2 + 1) dt - 2 * 1

Evaluating the integral, we get:

PS = [1/3 * t^3 + t] [0, 1] - 2

Plugging in the values, we have:

PS = (1/3 * 1^3 + 1) - (1/3 * 0^3 + 0) - 2

Simplifying the expression, we find:

PS = (1/3 + 1) - 2 = (4/3) - 2 = -2/3

Therefore, the producer's surplus for the supply function \(S(x) = x^2 + 1\) at x = 1 is approximately -0.67 units.

Answer:

x = 24.0

Step-by-step explanation:

We will need to use one of the trigonometric ratios to find x.  

If we use 58 as the reference angle, we can use tan to find x, as \(tan=\frac{opposite}{adjacent}\)

\(tan (58)=\frac{x}{15}\\ 15*tan(58)=x\\x=24.005\\x=24.0\)

Answer:

\(\boxed {x > -0.91}\)

Step-by-step explanation:

Solve for \(x\) :

\(x + 5.39 > 4.48\)

-Subtract \(5.39\) on both sides:

\(x + 5.39 - 5.39 > 4.48 - 5.39\)

\(x > -0.91\)

So, therefore, the final answer is \(\boxed {x > -0.91}\).

Answer:

(6,-6)

Step-by-step explanation:

The required coordinates of B is (6,-6).

In geometry, a line segment is a part of a line that is bounded by two end points, and contains every point on the line that is between end points.

Now it is given that,

Midpoint M (x,y) = (2,-7)

Coordinates of A( x₁,y₁) = (-2,-8)

Let the coordinates of B be (x₂,y₂)

Since, midpoint of line segment AB is given as,

{[(x₁+x₂ )/2] , [(y₁+y₂ )/2]}

Therefore,

x = (x₁+x₂ )/2

⇒ 2x = (x₁+x₂)

⇒ x₂ = 2x - x₁

Putting the values we get,

x₂ = 2(2) - (-2)

⇒ x₂ = 4 + 2

⇒ x₂ = 6

Similarly,

y₂ = 2y - y₁

Putting the values we get,

y₂ = 2(-7) - (-8)

⇒ y₂ = -14 + 8

⇒ y₂ = -6

so, the coordinates of B is (6,-6)

Thus, the required coordinates of B is (6,-6).

Answer:

198

Step-by-step explanation:

?/4        110/5

cross-multiply 4*110

440

divide 440/5

88 men

add total employees

110 women + 88 men = 198

(a) a= -45.43 and b = 40.06 and (b) R² = 0.56

(c) the variation in the independent sample values of weekly gross revenue

Y= - 42.57 + 22.40X₁ + 19.50X₂

a) Using X: TV Advertising Volume as the independent variable, you need to test simple linear regression.

The first step is to estimate the regression model

E(Yi) = α + βXi

Then ^Yi = a + bXi

where "a" is the estimate of the intercept and "b" is the estimated slope of the intercept.

Using statistical software, I calculated a simple linear regression as follows:

a= -45.43

b= 40.06

^Yi= -45.43 + 40.06Xi

To test whether there is a significant relationship between TV advertising and total weekly income, one needs to test the population slope of the regression, assuming:

H₁: β ≠ 0

α: 0.05

We have two ways to test if the regression is significant, you can use two-tailed t-test or one-tailed F-test. They are two different distributions and tests, but you can get the same result.

I will use a t-test for this item and an F-test for later tests.

 t = b-β/Sb × t(n-2)

\(t_{H0} = \frac{40.06 -0}{14.64} = 2.74\)

The p-value for this test is 0.0339

Using the p-value method, the decision rule is:

If the p-value ≤ α, the decision to reject the hypothesis is .

Decided not to reject the null hypothesis if the value of p > α.

p-value: 0. 0339 is less than α: 0.05, we decide to reject the null hypothesis. conclude that there is a significant relationship between television advertising and the sample total weekly revenue.

Looking at the estimated value of the slope, these two variables can have a direct relationship, namely

With each additional TV advertising volume, the total weekly revenue also increases. (This is just a hypothesis, without proper hypothesis testing you cannot draw any conclusions)

b) To find out what percentage of the change in total weekly income is explained by the model, you need to calculate the coefficient of determination.

For item a), the coefficients are:

R²= 0.56

This means that 56% of the variability in total weekly income is explained by the amount of television advertising according to the estimated model: ^ Yi= -45 .43 + 4.06Xi

c) This time you need to formulate the regression equation with two independent variables, namely:

X₁: Volume of TV ads

X₂: Volume of newspaper ads

The model will be

\(E(yi) = \alpha +\beta _{1} X_1 +\beta _{2} X_2\)

The model is ^Y = -42.57 + 22.40X₁ + 19.50X₂

For this hypothesis test, it is better to use the F-test

1) Intersection

H₀: α = 0

H₁: α ≠ 0

\(t_{H0} =-1.49\)

The p-value is greater than the significance level and it is decided not to reject the null hypothesis.

2) Slope of X₁

H₀: β₁ = 0

H₁: β₁≠0

α: 0.05

\(t_{H0} = 3.16\)

The 4th value is less than the null hypothesis for decision rejection.

Using a 5% significance level, the regression is significant.

3) Slope for X₂

H₀: β₂ = 0

H₁: β₂ ≠ 0

α: 0.05

\(t_{H0} = 5.27\)

e) The number of newspaper advertisements will affect the average weekly gross income.

d) The multivariate regression corresponds to a coefficient of determination of R²= 0.9393% of the variability of the average weekly gross income is explained by the combined volume of TV and newspaper advertisements under the estimated model:

Y= - 42.57 + 22.40X₁ + 19.50X₂

By comparing the results in a) and c), we can say that the two independent variables explain the dependent variable well.

Comparing the R² of the two, it can be said that TV advertising volume alone does not explain the fluctuation in total weekly income very well, but together with newspaper advertising volume, it becomes a good explanatory variable .

The predetermined overhead rate is the estimated manufacturing overhead cost per unit of a specific allocation base.

In the options, there are four different rates:

1. $10.00 / MH (MH stands for machine hour): This means that the estimated manufacturing overhead cost per machine hour is $10.00.

2. $17.50 / MH: This indicates that the estimated manufacturing overhead cost per machine hour is $17.50.

3. $20.00 / MH: This implies that the estimated manufacturing overhead cost per machine hour is $20.00.

4. $32.86 / MH: This shows that the estimated manufacturing overhead cost per machine hour is $32.86.

Each rate represents the estimated cost of manufacturing overhead per unit of the allocation base (machine hour) and is used to allocate overhead costs to products or services based on their usage of the allocation base.

The specific rate chosen depends on the nature of the business, its cost structure, and the accuracy of the estimated overhead costs.

The correct question is ''What is the predetermined overhead rate?\(\( \$ 10.00 / \mathrm{MH} \) \( \$ 17.50 / \mathrm{MH} \) \( \$ 20.00 \) / MH \( \$ 32.86 / \mathrm{MH} \)\).''

         Tip: You seem like you are slightly stuck. That is okay! Don't forget the formulas that can help you solve for the circumference. When you can solve for the circumference, the rest of the answers come a bit easier.

[a] 88 inches

         The circumference can be found with C = 2πr, but they tell us to use \(\frac{22}{7}\) instead of pi, so we will do just that.

C = 2 * \(\frac{22}{7}\) * r

C = 2 * \(\frac{22}{7}\) * (14)

C = 88

[b] 176 inches

         Again, the circumference can be found with C = 2πr, but they tell us to use \(\frac{22}{7}\) instead of pi, so we will do just that.

C = 2 * \(\frac{22}{7}\) * r

C = 2 * \(\frac{22}{7}\) * (28)

C = 176

[c] When you double the radius, the circumference also doubles.

         We will divide the second circumference by the first circumference  so we can see how they compare:

176 / 88 = 2

         Now we will take the second radius divided by the first radius:

28 / 14 = 2

         We could use a longer explanation, but in summary, when the radius is doubled the circumference is also doubled as seen with the value 2.

The main goal of the mathematical branch known as statistical inference is to estimate the likelihood that a statement is accurate or that a particular event will take place. Any number among 0 and 1, where 1 typically denotes confidence and 0 typically denotes possibility, can be used to symbolise chance. A probability diagram illustrates the likelihood that a particular occurrence will take place.

Here,

Because of the skewed demographic distribution, the right response is (a).

We could use the normally distributed to compute probabilities because the length of adult American ladybirds is distributed normally with a known standard deviation. The normal distribution may not, however, correctly depict the distribution of ladybird lengths in the population due to the skewed population distribution.

Furthermore, even if the difference between the actual community mean and the assumed mean of 1 cm is tiny, the given size of the population of 440000 could result in a statistically significant outcome.

However, because the assumption of normality may not hold true, this does not imply that we can accurately determine the likelihood of a random ladybird in Raleigh being larger than 1.5 centimetres.

Seraphina's speed has increased by a factor of around 23% compared to the first hour.

What Is a Change in Percentage?

The ratio of the difference in the amount to its starting value multiplied by 100 is known as the percentage change. When a number's final value is determined by increasing or decreasing a percentage of its starting value, the percentage change of that quantity will always change.

How can you determine the percentage to the closest tenth?

Rounding to the closest tenth entails adding one integer after the decimal point. The number in the thousandths place, or the second number from the right of the decimal, must be considered while rounding. If the amount is five or more, we add one percent to the number in the tenth position.

Percent Change Formula = \(\frac{ (Final value -Initial value)}{ (Initial value)}\)× 100

Percent Change               = \(\frac{(74-60)}{60}\)× 100

…                                     = \(\frac{14}{60}\) × 100

...                                     ≈ 0.23333 × 100

The formula for combinations is used to calculate the number of ways we can select r individuals from a total of n individuals. This formula is nCr = n!/r!(n-r)!. In this case, n is 6 (the total number of individuals in the group) and r is 2 (the number of individuals to be selected). Therefore, we substitute n=6 and r=2 into the formula to obtain the number of selections possible.

Explanation:

Here, (2, 13π/6) is given in polar coordinates.

So, we need to convert it into rectangular coordinates (x, y) to plot the given point in the cartesian plane.

The relation between polar and rectangular coordinates is given below:  

x = r cos θ, y = r sin θ

where r is the distance of the point from the origin, and θ is the angle made by the line joining the point and the origin with the positive x-axis.  

Therefore,

we have:

r = 2, θ = 13π/6  

Substituting these values in the above equations,

we get:  

x = 2 cos (13π/6)

  = 2(-√3/2)

  = -√3  y

  = 2 sin (13π/6)

  = 2(-1/2)

The correct equation that states the relationship between the dot distances and speeds is dot speed = dot distance / 5 hr. The correct option is (b).

This is because the dots are observed to be moving away from the observer at a constant rate, which is given in units of centimeters per hour.

This equation correctly represents the observed relationship because it implies that the speed at which a dot is moving away from you is directly proportional to its distance from you.

The coefficient of proportionality in this case is 1 cm/hr per 5 cm of distance.

This means that for every 5 centimeters of distance, the dot's speed increases by 1 centimeter per hour. As the distance increases, the speed also increases proportionally.

This is consistent with the information where dots at greater distances have higher speeds.

Therefore, to relate the dot distance (in centimeters) to the dot speed (in centimeters per hour), we need to divide the dot distance by the time taken for the dot to move that distance, which is 5 hours for all dots.
