Of the four variables, employee number, pay rate, hire date, and sex, the "Sex" variable is the best fit to use as a dummy variable.

The variable "Sex" is the best fit to use as a dummy variable. A dummy variable is used to represent a categorical variable with a numerical value, such as 0 or 1. In this case, "Sex" is a categorical variable with two categories (male and female) and can be transformed into a dummy variable with values 0 or 1 to represent the categories. The other variables, Employee Number, Pay Rate, and Hire Date, are not categorical variables and would not be appropriate to use as dummy variables.

Answer:

43.98

Step-by-step explanation:

The circumference of a circle with a radius of 7 units is approximately 43.98 units, which corresponds to option A.

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

Given that the radius of the circle is 7 units, we can substitute this value into the formula:

To find the circumference of a circle, we can use the formula C = 2πr, where C represents the circumference and r represents the radius.

C = 2π(7) = 14π

Use the approximation π ≈ 3.14:

C ≈ 14(3.14) = 43.96

Rounding this value to the nearest hundredth, we get approximately 43.98 units.

Therefore, the circumference of a circle with a radius of 7 units is approximately 43.98 units.

The equation of the hyperbola for the cross section of the cooling tower is x²/8100 - y²/9506.25 = 1.

We must take into account its characteristics in order to formulate the hyperbola's equation for the cooling tower's cross section.

Since the origin serves as the hyperbola's centre, its coordinates are (0, 0).

The left/right opening of the hyperbola indicates that the primary axis is horizontal.

The cooling tower's smallest diameter is 180 metres, which is the same length as the minor axis.

The primary axis' 195 m length and the diameter at its highest point are matched.

The hyperbola's highest point is 80 metres above the centre.

These characteristics allow us to write the hyperbola's equation in standard form:

(x - h)²/a² - (y - k)²/b² = 1

Where (h, k) represents the center of the hyperbola.

Substituting the given values:

Center: (h, k) = (0, 0)

Minor axis: 2a = 180 m, so a = 90 m

Major axis: 2b = 195 m, so b = 97.5 m

Vertical shift: c = 80 m

Now we can write the equation of the hyperbola:

x²/90² - y²/97.5² = 1

Simplifying, we have:

x²/8100 - y²/9506.25 = 1

An operations manager has carefully examined the 1500 parts produced in his factory and classified them into 30 families with geometric similarities using codes that contain design attributes. This is an example of: group technology.

Group technology is a manufacturing philosophy that seeks to improve efficiency and productivity by grouping similar parts together and standardizing their production processes.

By grouping similar parts together, manufacturing processes can be standardized and streamlined, reducing the time and cost associated with producing each part. This approach is particularly effective in high-volume manufacturing operations where a large number of parts are produced repeatedly.

In this case, the operations manager has identified 30 families of parts with geometric similarities and used codes that contain design attributes to classify them. By doing so, the manager has created a basis for grouping similar parts together and standardizing their production processes. This can lead to a more efficient and cost-effective manufacturing operation.

The combination of X = 12 and Y = 2.6 will yield the optimum solution for this linear programming problem, with a minimum value of 310.4 for the objective function. The correct answer is option c.

To solve this linear programming problem, we need to find the combination of X and Y that will yield the optimum solution while satisfying all the given constraints. Let's analyze each option:

a. 15,0: If we substitute these values into the constraints, we can see that the first constraint is not satisfied: 15(15) + 31(0) = 225 ≠ 465. Therefore, this option does not yield the optimum solution.

b. Unbounded problem: An unbounded problem occurs when there are no constraints on the variables, allowing them to increase or decrease infinitely while still improving the objective function. In this case, there are constraints on the variables X and Y, so the problem is not unbounded.

c. 12,2.6: Substituting these values into the constraints, we find that all the constraints are satisfied:

First constraint: 15(12) + 31(2.6) = 465 (satisfied)

Second constraint: 13(12) + 15(2.6) = 195 (satisfied)

Third constraint: 17(12) - 2.6 ≤ 201.4 (satisfied)

Now, let's calculate the objective function for this option: 14(12) + 21(2.6) = 310.4. Since the objective function is to minimize, this option provides the optimum solution with a value of 310.4.

d. Infeasible problem: An infeasible problem occurs when there is no feasible solution that satisfies all the constraints. In this case, we have found a feasible solution in option c, so the problem is not infeasible.

e. 0,13: If we substitute these values into the constraints, we can see that the third constraint is not satisfied: 17(0) - 13 > 201.4. Therefore, this option does not yield the optimum solution.

Kevin traveled a total of 315 miles in the journey from Glasgow to Newcastle and then to Nottingham.

To calculate the total distance Kevin traveled, we need to find the distance traveled in each leg of the journey and then add them together.

First, let's calculate the distance from Glasgow to Newcastle.

Kevin drove at an average speed of 60 mph for 2 hours and 30 minutes, which is equivalent to 2.5 hours.

Distance from Glasgow to Newcastle = Speed \(\times\) Time

= 60 mph \(\times\) 2.5 hours.

= 150 miles.

Next, let's calculate the distance from Newcastle to Nottingham.

Kevin drove at an average speed of 55 mph for 3 hours.

Distance from Newcastle to Nottingham = Speed \(\times\) Time.

= 55 mph \(\times\) 3 hours.

= 165 miles.

Finally, to find the total distance traveled, we add the distance from Glasgow to Newcastle and the distance from Newcastle to Nottingham:

Total distance traveled = Distance from Glasgow to Newcastle + Distance from Newcastle to Nottingham

= 150 miles + 165 miles.

= 315 miles.

Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

To find out how much of each leftover paint Josh should mix to achieve a medium pink color (50% red), we can set up a system of equations based on the percentages of red in the paints.

Let's assume that Josh needs x gallons of dark pink paint and y gallons of light pink paint to achieve the desired color.

The total amount of paint needed is 3 gallons, so we have the equation:

x + y = 3

The percentage of red in the dark pink paint is 80%, which means 80% of x gallons is red. Similarly, the percentage of red in the light pink paint is 30%, which means 30% of y gallons is red. Since Josh wants a 50% red mixture, we have the equation:

(80/100)x + (30/100)y = (50/100)(x + y)

Simplifying this equation, we get:

0.8x + 0.3y = 0.5(x + y)

Now, we can solve this system of equations to find the values of x and y.

Let's multiply both sides of the first equation by 0.3 to eliminate decimals:

0.3x + 0.3y = 0.3(3)

0.3x + 0.3y = 0.9

Now we can subtract the second equation from this equation:

(0.3x + 0.3y) - (0.8x + 0.3y) = 0.9 - 0.5(x + y)

-0.5x = 0.9 - 0.5x - 0.5y

Simplifying further, we have:

-0.5x = 0.9 - 0.5x - 0.5y

Now, rearrange the equation to isolate y:

0.5x - 0.5y = 0.9 - 0.5x

Next, divide through by -0.5:

x - y = -1.8 + x

Canceling out the x terms, we get:

-y = -1.8

Finally, solve for y:

y = 1.8

Substitute this value of y back into the first equation to solve for x:

x + 1.8 = 3

x = 3 - 1.8

x = 1.2

Therefore, Josh should mix 1.2 gallons of dark pink paint and 1.8 gallons of light pink paint to achieve the desired medium pink color.

Answer:Number of children = 2 and number of adults = 9 attended the play

Step-by-step explanation:

Step 1

Let the  number  of children be represented as  x

and the number of adults in the group  be represented as  as y

such that the total number of the group that went to the play

= x+y=11--- equation 1

And the total cost paid for the play will be expressed as

15x+  22y= 228------ equation 2

Step 2-- Solving

x+y=11--- equation 1

15x+  22y= 228------ equation 2

B y elimination method, multiply equation 1 by 15 to give equation 3  and then subtract from equation 2

15x+  22y= 228------ equation 2

15x+15Y= 165----- equation 3

7y=63

y= 63/7= 9

y= adults = 9
