Based on the given mean delivery time of 10:28am and the standard deviation of 0:55 mins, the estimated times within which 95% of the deliveries are made is (a) between 8:38 am and 12:18 pm.

To calculate this interval, we need to use the z-score formula, where we find the z-score corresponding to the 95th percentile, which is 1.96. Then, we multiply this z-score by the standard deviation and add/subtract it from the mean to get the upper and lower bounds of the interval.

The upper bound is calculated as 10:28 + (1.96 x 0:55) = 12:18 pm, and the lower bound is calculated as 10:28 - (1.96 x 0:55) = 8:38 am.

Therefore, we can conclude that the interval between 8:38 am and 12:18 pm represents the estimated times within which 95% of the deliveries are made based on the given mean delivery time and standard deviation.

The car's speed is 60 km/hour.

Let's denote the distance from the starting point to the destination by D, and let's denote the car's speed by S.

Using the formula speed = distance / time.

S = d  / t = (D - 200) / 1  ---- (1)

S = d / t = (D - 80) / 3  ----- (2)

We can simplify equation (2) by multiplying both sides by 3:

Expanding the right-hand side:

3S = D - 80

From equation 1 and 2:

3 (D - 200) = D - 80

3D - 600 = D - 80

3D - D = 600 - 80

2D = 520

D = 260

Therefore, the distance from the starting point to the destination is 260 km.

Using equation (1), we can find the car's speed:

S = 260 - 200 / 1

S = 60 m/s

Therefore, the car's speed is 60 km/hour.

The solution to the equation (1/(h-5)) - (2/h) = 0 is h = 10.

To find the solution to the equation startfraction 1 over h minus 5 endfraction  startfraction 2 over h  5 end fraction, we need to first simplify the equation. To do this, we need to find a common denominator for the two fractions.
The least common multiple of h and 5 is 5h, so we can rewrite the equation as:
startfraction 5h over h(5h) minus 25 over h(5h) endfraction
Now, we can combine the fractions by subtracting the numerators:
startfraction 5h - 25 over h(5h) endfraction
Simplifying further, we can factor out 5 from the numerator:
startfraction 5(h - 5) over h(5h) endfraction
Finally, we can cancel out the common factor of 5:
startfraction h - 5 over h^2 endfraction
Therefore, the solution to the equation startfraction 1 over h minus 5 endfraction  startfraction 2 over h  5 end fraction is startfraction h - 5 over h^2 endfraction.
Hi! To solve the equation involving the given fractions 1/(h-5) and 2/h, let's follow these steps:
Write down the given equation.
(1/(h-5)) - (2/h) = 0
Find the least common denominator (LCD) of the fractions.
In this case, the LCD is h * (h-5).
Multiply each fraction by the LCD to eliminate the denominators.
[(1/(h-5)) * h * (h-5)] - [(2/h) * h * (h-5)] = 0 * h * (h-5)
Simplify the equation.
(h * 1) - (2 * (h-5)) = 0
Distribute the negative sign and solve for h.
h - 2h + 10 = 0
Combine like terms.
-h + 10 = 0
Add h to both sides of the equation.
10 = h
So, the solution to the equation (1/(h-5)) - (2/h) = 0 is h = 10.

The given parabolic equation is y = 4x - x² and the point is (1, 3). We are to determine the slope of the tangent line at (1, 3) and then obtain an equation of the tangent line.  we must first calculate the derivative of the given equation.

We can do this by using the power rule of differentiation. The derivative of x² is 2x. So the derivative of y = 4x - x² is dy/dx = 4 - 2x.Since we want to find the slope of the tangent line at (1, 3), we need to substitute x = 1 into the equation we just obtained. dy/dx = 4 - 2x = 4 - 2(1) = 2. Therefore, the slope of the tangent line at (1, 3) is 2.We can now write the equation of the tangent line. We know the slope of the tangent line, m = 2, and we know the point (1, 3).

We can use the point-slope form of the equation of a line to obtain the equation of the tangent line. The point-slope form of the equation of a line is given as: y - y₁ = m(x - x₁)where m is the slope, (x₁, y₁) is a point on the line.Substituting in the values we have, we get:y - 3 = 2(x - 1)We can expand this equation to obtain the slope-intercept form of the equation of the tangent line:y = 2x + 1Therefore, the equation of the tangent line to the parabola y = 4x - x² at the point (1, 3) is y = 2x + 1.

Common multiples and denominators are both concepts related to numbers, but they have different roles and purposes. Common multiples are used to find numbers that are multiples of two or more given numbers, while denominators specifically refer to the bottom number in a fraction.

Common multiples are numbers that are divisible by two or more given numbers. They are used to find numbers that are evenly divisible by a set of numbers. For example, the common multiples of 3 and 4 are 12, 24, 36, etc., as these numbers are divisible by both 3 and 4.

Denominators, on the other hand, are specific to fractions. In a fraction, the denominator represents the bottom number, indicating the total number of equal parts into which the whole is divided. It determines the size and proportion of each part of the fraction. For instance, in the fraction 3/5, the denominator is 5, indicating that the whole is divided into five equal parts.

While common multiples involve finding numbers divisible by given numbers, denominators are exclusively used in fractions to represent the number of equal parts in a whole. In this way, they serve different purposes. However, they are alike in the sense that they both deal with numbers and can be used in mathematical calculations and relationships.

Answer: Research

Step-by-step explanation:

The probability of producing less than 239,000 barrels is 0.8413.

The probability of producing less than 239,000 barrels can be found using the z-score formula. The z-score formula is given by:
z = (x - μ) / σ
Where x is the value we are interested in, μ is the mean, and σ is the standard deviation.
Plugging in the given values, we get:
z = (239,000 - 232,000) / 7,000
z = 1
Now, we can use the standard normal table to find the probability of producing less than 239,000 barrels. The standard normal table gives the probability of a value being less than a given z-score. For a z-score of 1, the probability is 0.8413.

From the calculation carried out below, it can be observed that the profit for 50 sales is $110.

How do we calculate profit for sales?

Given revenue as:

f(x) = 4x ............................ (1)

Where:

x = Number of bracelets sold or sales = 50

Total obtain the revenue, substitute x = 50 into equation (1), we have:

Revenue = f(50) = 4 *50

Revenue = $200

Since profit is $10 less than 80% of the revenue, we have:

Profit = (Revenue * 80%) - 10

Profit = (200 * 80%) - 50

Profit = 160 - 50

Profit = $110

The housing supply function is given by h(I,R) = a log1 + bR + cR log1. The housing supply responds to changes in I with a rate of a, and to changes in R with a rate of b + c log1.

Based on the given equation, the housing supply (h) is determined by two variables: I and R. The equation shows that h is a function of R, with a log-linear relationship. The variable I only appears as a constant (a) in the equation, so changes in I do not directly affect the supply of houses.
On the other hand, changes in R (or OR, which is the same variable) do affect the supply of houses. Specifically, an increase in R leads to an increase in the supply of houses. The magnitude of this increase depends on the values of b and c in the equation.
To see this, we can take the partial derivative of h with respect to R:
dh/dR = b + cR/(ln(10))
This equation tells us how much the housing supply changes in response to a change in R. The derivative is positive (i.e. the supply increases) as long as c is positive. The larger c is, the greater the increase in supply for a given increase in R.
Therefore, the correct answer is:
b + cR/(ln(10))

Cable television is a form of television programming that is delivered to subscribers through a coaxial or fiber-optic cable network. It typically offers a wide range of channels and programming options, including news, sports, movies, and TV shows.

For the residents of Oak Vista, cable television is a mandatory service that is included in their monthly rent or housing fees. This means that all residents are required to pay $60 per month for the cable TV service, regardless of whether they use it or not. This is known as a bundled service, where a single fee is charged for multiple services or products.

The reason for the mandatory cable TV service is likely due to the fact that the apartment complex has a contract with a cable TV provider, and the cost of the service is spread across all residents. Additionally, offering a bundled service can be a way for the complex to offer a lower overall price for cable TV, since the cost is spread across a larger group of people.

While some residents may not want or need cable TV, the mandatory fee means that they must pay for the service regardless. However, some complexes may offer alternative options or allow residents to opt-out of the service for a reduced fee.

The dependent variable is the variable that is being measured or observed in an experiment. It is the outcome or response variable that is expected to change as a result of manipulating the independent variable(s). In this case, the independent variable is the type of diet (low-carb or high-carb), and the dependent variable is the average number of pounds lost by the participants.

The researchers are comparing the average weight loss between the two groups: one following a low-carbohydrate diet and the other following a high-carbohydrate diet with the same number of calories. They are interested in determining whether the type of diet has an effect on weight loss. Hence, the dependent variable is the average number of pounds lost, as it is the variable that is expected to vary based on the diet type.
