Total hours handled by x judges in the year ≤ 12120x where x is the number of judges needed to handle the caseload for the year.

To formulate an LP for this problem, we can define the decision variables and the objective function and constraints.

Decision Variables:

Let x be the number of judges needed by the city to handle the caseload for the year.

Objective Function:

We want to minimize the number of judges needed, so our objective function is:

minimize x

Constraints:

Each judge can handle up to 120 hours of caseload per month, so the total number of hours that can be handled by x judges in a month is 120x. The total number of hours needed to handle the caseload for the year is given in the table. Therefore, we have the following constraints:

For January: 120x ≥ 100

For February: 120x ≥ 120

For March: 120x ≥ 90

For April: 120x ≥ 80

For May: 120x ≥ 110

For June: 120x ≥ 130

For July: 120x ≥ 140

For August: 120x ≥ 110

For September: 120x ≥ 100

For October: 120x ≥ 90

For November: 120x ≥ 80

For December: 120x ≥ 120

These constraints ensure that the total number of hours handled by the judges in each month is at least as much as the number of hours needed to handle the caseload in that month.

We also need to ensure that all cases are handled by the end of December. This can be expressed as follows:

Total hours handled by x judges in the year ≤ 12120x

This constraint ensures that the total number of hours handled by the judges in the year is less than or equal to the maximum possible number of hours that can be handled by x judges in a year.

Therefore, the LP can be formulated as follows:

minimize x

subject to:

120x ≥ 100

120x ≥ 120

120x ≥ 90

120x ≥ 80

120x ≥ 110

Answer:

Step-by-step explanation:

Let's call the length of each shorter piece of the first pipe x. Then the total length of the first pipe would be 5x + 27 cm.

Similarly, the length of each shorter piece of the second pipe would be x and the total length of the second pipe would be 11x + 15 cm.

Since both pipes were cut into the same length pieces, we can set the two equations equal to each other:

5x + 27 = 11x + 15

Solving for x, we can find the length of each shorter piece:

6x = -12

x = -2

This means that each shorter piece of both pipes was -2 cm long, which is not physically possible. So, this solution is not valid. This means that the problem is underdetermined and that we cannot determine the length of each piece.

Answer:

ferris wheel: 2

roller coaster: 4

Step-by-step explanation:

Variables

y = ferris wheel tickets

x = roller coaster tickets

Two equations

5y + 4x = 26

5y + 3x = 22

Using Elimination (minus the top and bottom)

We get:

x = 4 (because 5y - 5y is zero, 4x - 3x is x, and 26 - 22 is 4)

Since the roller coaster price is know, you can sub it into any of the two equations and fine ferris wheel price.

5y + 3(4) = 22

5y + 12 = 22

5y = 10

y = 2

Therefore:

ferris wheel charges 2 tickets

roller coaster charges 4 tickets

Answer:

118

Step-by-step explanation:

Let the original number be x.

After subtracting 3, the result is x - 3.

When this result is multiplied by 5, we get (x - 3) * 5 = 575.

Expanding and solving for x, we have:

5x - 15 = 575

5x = 590

x = 118

So the original number was 118.

Equation that we can use to find the amount of money, p, Roman Rounds normally charges for a large pizza is 12(p - 2) = 192.

Let's use p to represent the normal price of a large pizza from Roman Rounds. Since Mr. Mosley ordered 12 large pizzas and received a $2 discount on each, he paid a total of $192. We can use this information to set up the following equation:

12(p - 2) = 192

In this equation, 12 represents the number of large pizzas that were ordered, and (p - 2) represents the discounted price of each pizza. The left side of the equation gives us the total amount that Mr. Mosley paid for the pizzas. By setting this expression equal to 192, we can solve for p, the normal price of a large pizza from Roman Rounds.

To solve for p, we first distribute the 12 on the left side of the equation:

12p - 24 = 192

Next, we add 24 to both sides of the equation:

12p = 216

Finally, we divide both sides of the equation by 12:

p = 18

Therefore, the normal price of a large pizza from Roman Rounds is $18.

The required perimeter of the door on the scale drawing is 4 cm, which is option A.

Perimeter is the measure of the figure on its circumference.

Here,
To find the perimeter of the door on the scale drawing, we need to first find the dimensions of the door on the scale drawing. We can use the scale 2:8 to convert the actual dimensions of the door to the corresponding dimensions on the scale drawing:

Height on scale drawing = (2/8) x 5 cm = 1.25 cm

Width on scale drawing = (2/8) x 3 cm = 0.75 cm

The perimeter on the scale drawing = 2 x (height on scale drawing + width on scale drawing)

Perimeter on scale drawing = 2 x (1.25 cm + 0.75 cm)

Perimeter on scale drawing = 2 x 2 cm

The perimeter on the scale drawing = 4 cm

Therefore, the perimeter of the door on the scale drawing is 4 cm, which is option A.

Using the gradient of the curve given, the value of a is 6

The stationary point of a curve is a point where the slope of the curve is equal to zero. So, to find the value of a, we need to set the derivative of the curve equal to zero and solve for x.

dy/dx = 2(x + 3)^(1/2) - x

Setting this equal to zero, we have:

2(x + 3)^(1/2) - x = 0

Expanding the square root and rearranging, we get:

x = 2(x + 3)^(1/2)

Squaring both sides of the equation, we have:

x^2 = 4(x + 3)

Expanding the right side and rearranging, we have:

x^2 - 4x - 12 = 0

Using the quadratic formula, we can find the values of x that satisfy this equation:

x = [-(-4) ± √((-4)^2 - 4(1)(-12))] / 2(1)

x = [4 ± √(16 + 48)] / 2

x = [4 ± √64] / 2

x = [4 ± 8] / 2

So, the two possible values of x are:

x = 6, x = -2

Since we are looking for a positive value of x, the only solution that works is x = 6.

Therefore, the value of a is equal to 6.

The proportion of the time that Mrs. Starnes finishes an easy sudoku puzzle in less than 3 minutes is approximately 0.0055, or 0.55%

We can use the normal distribution and the given mean and standard deviation to find the proportion of the time that Mrs. Starnes finishes an easy sudoku puzzle in less than 3 minutes.

First, we need to standardize the value of 3 minutes using the z-score formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean, and σ is the standard deviation.

Substituting the given values, we get:

z = (3 - 5.3) / 0.9 ≈ -2.56

Next, we can use a standard normal distribution table or a calculator to find the proportion of the area under the standard normal distribution curve that corresponds to a z-score of -2.56. This proportion represents the proportion of the time that Mrs. Starnes finishes an easy sudoku puzzle in less than 3 minutes.

Using a standard normal distribution table, we can find that the area to the left of z = -2.56 is approximately 0.0055.

Therefore,

The proportion of the time that Mrs. Starnes finishes an easy sudoku puzzle in less than 3 minutes is approximately 0.0055, or 0.55%.

The definition of average value of a function is -"The average value of a function is the height of the rectangle that has an area that is equivalent to the area under the curve of the function."

When there's a need to find the average value of a function, rather than adding up numbers we can just integrate, and instead of dividing by the number of values we can just divide by the length of the interval.

Adding values → Integration

Number of values → Length of the interval

When we use the length of the interval it makes more sense as we all know intervals have an infinite number of values, so it is more appropriate to use the length of the interval instead.

The standard form of the equation of the quadratic function is y = -1/8x^2 + 1/4x - 41/8

From the question, we have the following parameters that can be used in our computation:

(h, k) = (1, -5)

(x, y) = (5, -7)

A quadratic function is represented as

y = a(x - h)^2 + k

So, we have

y = a(x - 1)^2 - 5

Given that

(x, y) = (5, -7)

We have

-7 = a(5 - 1)^2 - 5

This gives

16a = -2

So, we have

a = -1/8

Recall that

y = a(x - 1)^2 - 5

So, we have

y = -1/8(x - 1)^2 - 5

Expand

y = -1/8(x^2 - 2x + 1) - 5

Answer: Let's call the side length of the square pool "s". We know that the area of a square is equal to the length of one side squared, so we can set up an equation:

s^2 = 144

We can solve for s by taking the square root of both sides:

s = sqrt(144) = 12

So the side length of the pool is 12 feet.

The outside perimeter of the deck is equal to the perimeter of the square pool plus the width of the deck on each side (7 feet). So the outside perimeter is:

12 + 7 + 7 + 12 + 7 + 7 = 52 feet

So the outside perimeter of the deck is 52 feet.

Step-by-step explanation:

Answer: 52 feet

Step-by-step explanation:

First, we know this is a square. So, if the area is 144, square root of 144 is 12 (12 * 12 = 144)

Adding a width of 7 feet to each side means that we can add 12+12+7+7+7+7.

It will take Daniel approximately 2 hours and 52 minutes (172.066 minutes) to complete the triathlon.

To estimate how long it will take Daniel to complete the triathlon, we can calculate the time it will take him to complete each leg of the race and add them together.

Swim:

Distance = 0.93 miles

Speed = 2.2 mph

Time = Distance / Speed = 0.93 miles / 2.2 mph = 0.4236 hours = 25.416 minutes

Bike:

Distance = 24.8 miles

Speed = 17.8 mph

Time = Distance / Speed = 24.8 miles / 17.8 mph = 1.3933 hours = 83.6 minutes

Run:

Distance = 6.2 miles

Speed = 5.9 mph

Time = Distance / Speed = 6.2 miles / 5.9 mph = 1.0508 hours = 63.05 minutes

Total time = Swim time + Bike time + Run time

Total time = 25.416 minutes + 83.6 minutes + 63.05 minutes

Total time = 172.066 minutes

The college will have about 640 students who prefer pie. We can calculate percentages based on the student sampling of 225 students (assuming it was a completely random sample, and not one taken just from a specific group, such as football players at half-time).

What is random sample?

To make a prediction, we need to assume that the preferences of the 225 students surveyed are representative of the entire student population of 4,000. We can use the proportion of students who prefer pie in the sample to make an estimate.

The proportion of students who prefer pie in the sample is:

                36/225 = 0.16

We can use this proportion to estimate the number of students who prefer pie in the entire population:

                       4,000 x 0.16 = 640

Therefore, the best prediction about the slices of pie the college will need is that the college will have about 640 students who prefer pie. So the option "The college will have about 640 students who prefer pie" is the correct statement.
