The first car has a higher miles per gallon rating with 27.03

The miles per gallon (mpg) rating for a car, we can use the formula

mpg = 100 / (gallons per 100 miles)

For the first car with a rating of 3.7 gallons per 100 miles

mpg = 100 / 3.7 ≈ 27.03 mpg

For the second car with a rating of 4.3 gallons per 100 miles

mpg = 100 / 4.3 ≈ 23.26 mpg

Comparing the two mpg ratings, we find that the first car has a greater mpg rating of 27.03 mpg compared to the second car with a rating of 23.26 mpg. Therefore, the first car has a higher mpg rating.

We break the 6 into 3 and 2

The equation of the line tangent to the graph of f at (a,f(a)) for the given value of a is y=4x-9.

Given function f(x) = 2x² + 10x +9.The derivative function of f(x) is obtained by differentiating f(x) with respect to x. Differentiating the given functionf(x) = 2x² + 10x +9

Using the formula for power rule of differentiation, which states that \[\frac{d}{dx} x^n = nx^{n-1}\]f(x) = 2x² + 10x +9\[\frac{d}{dx}f(x) = \frac{d}{dx} (2x^2+10x+9)\]

Using the sum and constant rule, we get\[\frac{d}{dx}f(x) = \frac{d}{dx} (2x^2)+\frac{d}{dx}(10x)+\frac{d}{dx}(9)\]

We get\[\frac{d}{dx}f(x) = 4x+10\]

Therefore, the derivative function of f(x) is f'(x) = 4x + 10.2.

To find the equation of the tangent line to the graph of f at (a,f(a)), we need to find f'(a) which is the slope of the tangent line and substitute in the point-slope form of the equation of a line y-y1 = m(x-x1) where (x1, y1) is the point (a,f(a)).

Using the derivative function f'(x) = 4x+10, we have;f'(a) = 4a + 10 is the slope of the tangent line

Substituting a=-2 and f(-2) = 2(-2)² + 10(-2) + 9 = -1 as x1 and y1, we get the point-slope equation of the tangent line as;y-(-1) = (4(-2) + 10)(x+2) ⇒ y = 4x - 9.

Hence, the equation of the line tangent to the graph of f at (a,f(a)) for the given value of a is y=4x-9.

The dotplot depicts that Only 12% of the values of x were 64.7 or greater. Because this is such a small percentage it would be surprising to get a sample mean of 64.7 or larger in an SRS of size 20 from a Normal population with μ = 64 and σ = 2.5.

The dotplot shows that only 12% of the simulated sample means were 64.7 or greater. This means that it is unlikely to get a sample mean of 64.7 or greater if the population mean is actually 64. In other words, the evidence suggests that the population mean height is greater than 64 inches.

The first equation, 3^x = 12, is an exponential equation. To solve for x, we would take the logarithm of both sides with base 3:

x = log3(12)

The second equation, x^3 = 12, is a polynomial equation of degree 3. To solve for x, we would take the cube root of both sides:

x = ∛12

The similarity between these two equations is that both are equations with one variable and are looking for the value of that variable.

The main difference between these two equations is the type of function they represent. The first equation is an exponential function, represented by 3^x, while the second equation is a polynomial function, represented by x^3.

As a result, the methods used to solve these equations are also different. The first equation is solved by taking the logarithm of both sides and the second equation is solved by taking the cube root of both sides.

Step-by-step explanation:

a. When evaluating a model, we use R2 as a parameter for performance assessment.

b. If model A has a higher MAPE but model B has a higher R2, we choose the model with the higher R2 for better overall performance.

c. For accuracy measures, we typically use MAPE (Mean Absolute Percentage Error) due to its interpretability and ability to capture relative errors.

When evaluating a model's performance, it is crucial to choose the appropriate parameters to assess its accuracy and reliability. In the case of MAPE (Mean Absolute Percentage Error) and R2 (Coefficient of Determination), the choice between them depends on the specific evaluation goals.

The R2 parameter is commonly used for evaluating models because it measures the proportion of the dependent variable's variance that can be explained by the independent variables. R2 provides insights into how well the model fits the data and captures the relationship between the input features and the target variable. Therefore, R2 is a suitable parameter to use when evaluating a model.

When comparing two models, if model A has a higher MAPE but model B has a higher R2, it is advisable to choose the model with the higher R2 value. This is because R2 indicates the proportion of variance explained, suggesting that model B performs better in capturing the underlying patterns and predicting the target variable.

Although model A may have a lower relative error (MAPE), it is crucial to prioritize the model's ability to explain and predict the target variable accurately.

Among MAPE, MAD (Mean Absolute Deviation), and MSD (Mean Squared Deviation), MAPE is commonly preferred as a parameter for accuracy measures. MAPE calculates the average percentage difference between the predicted and actual values, making it interpretable and easily understandable.

It captures relative errors and enables comparisons across different scales and datasets. MAD and MSD, on the other hand, measure absolute and squared errors, respectively, but they do not account for the relative magnitude of the errors. Hence, MAPE is a more suitable parameter for accuracy measures.

Extra people required is 50.

Each of the five workers should increase their efficiency to a rate of 15 sandwiches per 10 hour shift.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Question 1 :

Number of associates = 30

Number of direct workers = 30 - 2 = 28

You work 8 hours a day and 5 days a week with two 15 minutes break or 30 minutes break per day.

Direct rate = 150 units per hour

Number of working hours in a week with break = 8 × 5 = 40 hours per week Number of working hours in a week = 7.5 hours per day × 5 days a week

                                                            = 37.5 hours per week

Units that department produce in a 40 hour week = 37.5 × 150 = 5625 units

28 people produce 5625 units in a week

Let x people produce 10,000 + 5625 = 15,625 units in a week

Using proportion,

28 : 5625 = x : 15,625

28 / 5625 = x / 15,625

x = (28 × 15,625) / 5625 = 77.78 ≈ 78

Extra people required = 78 - 28 = 50

Question 2 :

Number of sandwiches made in 10 minutes = 1

Number of sandwiches made in 10 hours = 60

5 workers are there. one worker makes 60/5 = 12 sandwiches

But Deli want number of sandwiches in 10 hours = 75

One worker should make 75/5 = 15 sandwiches instead of 12.

Number of sandwiches made in 8 minutes should be 1.

So the working efficiency on each worker should be increased and produce each one should produce 15 sandwiches in a 10 hour shift.

Hence extra people required in question 1 is 50 and efficiency of each worker in question 2 should be increased to 15 sandwiches in 10 hours shift.

The area of original face is equal to area of parallelogram that is = \(28 yd^{2}\)

and in the case of square feet it is = 252 square feet.

What about area?

Area is a mathematical term that refers to the measurement of a two-dimensional space or surface. It is the amount of space inside a flat, two-dimensional object or shape, and is usually expressed in units of square units, such as square meters, square feet, or square inches. The concept of area is important in many fields, including mathematics, engineering, physics, architecture, and geography, as it allows us to calculate the size of surfaces, the amount of material needed to cover them, and other important measurements.

Define area of parallelogram:

The area of a parallelogram is calculated by multiplying the length of its base by its height, where the height is the perpendicular distance between the base and the opposite side. Mathematically, we can express the formula as:

Area = base x height

where "base" is the length of the parallelogram's base and "height" is the distance between the base and the opposite side, measured perpendicular to the base.

According to the given information:

As, we see that the area of original face is equal to the area of parallelogram and the area of parallelogram = \(b\)×\(h\).

⇒ Area of parallelogram = \(b\)×\(h\)

In which breath = \(7yd\) and height = \(4yd\)

So, Area of parallelogram = \(7\)×4

                                           = \(28yd^{2}\)

When we convert it into square feet it is,

⇒ \(28yd^{2} = 28\) × \(9 ft^{2}\)
