Proportional reasoning refers to the ability to compare and analyze relationships between two or more quantities that change in a consistent way. It involves understanding the concept of proportionality and applying it to solve problems.

1.) If a business jet burns 300 gallons of gasoline per hour, it burns 900 gallons of gasoline in a three-hour flight. This can be calculated by multiplying the burn rate of 300 gallons per hour by the duration of the flight, which is three hours.

2.) On average, one gallon of gasoline weighs approximately six pounds. Therefore, fifty gallons of gasoline weighs 300 pounds. This can be calculated by multiplying the weight of one gallon (six pounds) by the quantity of fifty gallons.

3.) For every one yard, there are thirty-six inches. To find the number of yards in 2,124 inches, we divide 2,124 by 36. The result is 59 yards. This can be calculated by dividing the total number of inches by the conversion factor of thirty-six inches per yard.

4.) A person who weighs 240 pounds burns 180 calories per mile of running. A person who weighs 48 pounds, burns thirty-six calories while running one mile. To find the number of pounds for which the person burns thirty-six calories while running one mile, we can set up a proportion. If we let x represent the weight in pounds, the proportion would be: 240 pounds / 180 calories = x pounds / 36 calories. Solving for x gives us x = 48 pounds.

5.) A rice casserole recipe serves four people and requires two tablespoons of butter. If a rice casserole requires six tablespoons of butter, it serves twelve people. This can be determined by setting up a proportion: 4 people / 2 tablespoons = 12 people / 6 tablespoons. Solving for the unknown number of people gives us 12 people.

We need to sum at least one term to ensure that the remainder is less than\(10^{-6\).

We know that the alternating series test states that if a series is alternating and its terms are decreasing in absolute value, then the series converges. We can see that the series ∑[infinity]k=1(−1)kk4 is an alternating series because the signs of the terms alternate, and the terms decrease in absolute value because \(k_4\) > (k+1)4 for all k.

Now, we can use the remainder formula for an alternating series, which tells us that the remainder Rn of an alternating series ∑[infinity]k=1(−1)ka_k after n terms is less than or equal to the absolute value of the next term \(a_{n+1\):

|Rn| ≤ |\(a_{n+1\)|

So, we want to find the smallest value of n such that |a_n+1| < 10^(-6). We have:

\(a_k = (-1)^k \times k^4\)

\(a_{n+1} = (-1)^{(n+1)} \times(n+1)^4\)

We want to find n such that:

\(|(n+1)^4| < 10^{(-6)\)

Taking the fourth root of both sides, we get:

\(|n+1| < (10^(-6))^(1/4)\)

|n+1| < 0.1

n+1 < 0.1 or -(n+1) < 0.1

n < 0.1 - 1 or n > -0.1 - 1

n < -0.9 or n > -1.1

Since n must be a positive integer, the smallest possible value of n that satisfies this inequality is n = 1. Therefore, we need to sum at least one term to ensure that the remainder is less than \(10^{(-6)\).

The optimal solution for the given linear programming model is:

max z = 38

when x1 = 5, x2 = 10, x3 = 0

To solve the given linear programming model using the simplex algorithm, we start by converting the inequalities into equations and introducing slack variables. The initial tableau is constructed with the coefficients of the decision variables and the right-hand side constants.

Next, we apply the simplex algorithm to iteratively improve the solution. By performing pivot operations, we move towards the optimal solution. In each iteration, we select the pivot column based on the most negative coefficient in the objective row and the pivot row based on the minimum ratio test.

After several iterations, we reach the optimal tableau, where all the coefficients in the objective row are non-negative. The optimal solution is obtained by reading the values of the decision variables from the tableau.

In this case, the optimal solution is z = 38 when x1 = 5, x2 = 10, and x3 = 0. This means that to maximize the objective function, the decision variables x1 and x2 should be set to 5 and 10 respectively, while x3 is set to 0.

Answer:

85.71 %

Step-by-step explanation:

26-14=12

12/14= 0.8571

0.8571x100= 85.71

Answer:

A change from 14 to 26 represents a positive change (increase) of 85.7142857143%

Step-by-step explanation:

Use the formula:

New - Old / Old x 100%

In other words, new(26) minus old(14) divided by old(14) time 100%

14 is the old value and 26 is the new value. In this case we have a positive change (increase) of 85.7142857143 percent because the new value is greater than the old value.

Given that the vertex of the function is at the point (0, 0.5).We are required to find the recommended amount of mulch for a flowerbed with a radius of 20 feet.

Let us find the equation of the parabola with the vertex at (0,0.5).

The general equation of the parabola is given as:y = a(x - h)² + k

Where(h, k) = (0, 0.5)

=> h = 0 and k = 0.5

Therefore, the equation of the parabola is:

y = a(x - 0)² + 0.5y = ax² + 0.5

We have another point on the parabola given as (20, 2).We can use this point to find the value of a.

Substituting the point (20, 2) in the equation of the parabola we get:

2 = a(20)² + 0.52

= 400a + 0.5a

= 1.5/400

a = 3/8000

Substituting the value of a in the equation of the parabola, we get:

y = (3/8000)x² + 0.5

Let us now find the volume of the flowerbed with a radius of 20 feet.We know that the flowerbed is in the shape of a hemisphere.

Hence,Volume of the flowerbed = (2/3)πr³ = (2/3) × π × (20)³

= 33,510.32 cubic feet

Let us find the height of the flowerbed at a distance of 20 feet from the center.The distance from the center of the flowerbed to the edge is 20 feet.

Therefore, the point on the parabola at a distance of 20 feet from the origin will be (20, h).Let us find the value of h.

Substituting x = 20 in the equation of the parabola, we get:

h = (3/8000)(20)² + 0.5

= 0.8 feet

The height of the flowerbed at a distance of 20 feet from the center is 0.8 feet.The volume of the mulch required will be the volume of the hemisphere with radius 20 and height 0.8 feet.

Volume of mulch required = (2/3)πr²h

= (2/3) × π × (20)² × 0.8

= 6716.32 cubic feet

Therefore, the recommended amount of mulch for a flowerbed with a radius of 20 feet is 6716.32 cubic feet.

Therefore, the recommended amount of mulch for a flowerbed with a radius of 20 feet is 6716.32 cubic feet.

The most appropriate inference procedure for the researchers to use to analyze the results is a matched-pairs t-interval for a population mean difference.

A matched-pairs t-interval for a population mean difference is suitable for this study because it involves comparing the pretest and posttest scores of the same individuals.

The researchers are interested in determining whether there is a significant difference in the number of correct answers before and after the adult reading program.

By using a matched-pairs t-interval, the researchers can analyze the mean difference in scores and determine the range within which the true population mean difference is likely to fall. This inference procedure takes into account the paired nature of the data, accounting for individual differences and increasing the precision of the estimate.

It is important to use this procedure as it considers the correlation between the pretest and posttest scores for each individual, providing a more accurate assessment of the program's effectiveness.

The number of ways to divide 10 players into two teams of 5 with Steve and Danny on different teams is -3668, implying that it's impossible to divide the teams as such. This result shows that the probability of both players being on the same team is one, and is related to the complement of the probability of them being on opposite teams.

We have our basketball team has 10 players, including Steve and Danny, and we need to divide them into two teams of 5 for an intrasquad scrimmage.

The number of ways of selecting r objects out of n is given by ⁿCr where,

ⁿCr = (n!) / [(n - r)! r!]

Here, the number of ways to choose 5 players out of 10 is ¹⁰C₅.

¹⁰C₅ = (10!) / [(10 - 5)! 5!]

¹⁰C₅ = (10 x 9 x 8 x 7 x 6) / (5 x 4 x 3 x 2 x 1)

¹⁰C₅ = 252

There are 252 ways to divide the 10 players into two teams of 5.

Using complementary probabilities, we can find the number of ways in which the teams can be picked such that Steve and Danny are on the same team.

For that, we need to calculate the number of ways in which Steve and Danny can be together, and then subtract this from the total number of ways.

Using the same logic, the number of ways to choose 4 more players out of 8 is ⁸C₄.

⁸C₄ = (8!) / [(8 - 4)! 4!]

⁸C₄ = (8 x 7 x 6 x 5) / (4 x 3 x 2 x 1)

⁸C₄ = 70

There are 70 ways to choose 4 players from the remaining 8 (excluding Steve and Danny).

We can consider Steve and Danny as one player, so we need to select 3 more players from the remaining 8 (excluding Steve and Danny).

The number of ways to do this is ⁸C₃.

⁸C₃ = (8!) / [(8 - 3)! 3!]

⁸C₃ = (8 x 7 x 6) / (3 x 2 x 1)

⁸C₃ = 56

There are 56 ways to select 3 players from the remaining 8 to join Steve and Danny.

Using the multiplication principle, we get the number of ways to select the entire team as 70 x 56 = 3920.

There are 3920 ways to choose the teams so that Steve and Danny are on the same team.

Now, using the complement rule, the number of ways to select the teams so that Steve and Danny are on opposite teams is given by the total number of ways minus the number of ways in which Steve and Danny are on the same team.

Using this, we can say that the number of ways to divide the 10 players into two teams of 5 such that Steve and Danny are on opposite teams is given by 252 - 3920 = -3668.

However, the answer is negative which means that there is no way to divide the teams such that Steve and Danny are on opposite teams.

Hence, the solution to the problem is related to the complement of the probability.

the height of the helicopter above the ground is approximately 6928.2 ft when viewed by Amanda and approximately 2311.8 ft when viewed by Jeremiah

Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations.

There are six popular trigonometric functions for an angle. Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).

Let's denote the height of the helicopter above the ground as "h" and the horizontal distance between Amanda and Jeremiah as "d", which is 4000 ft in this case.

We can use trigonometry to calculate the height of the helicopter.

In triangle Amanda-helicopter-Jeremiah, we can use the tangent function to relate the angle of elevation to the height of the helicopter:

tan(60°) = h / d (for Amanda)

tan(30°) = h / d (for Jeremiah)

Solving for h in both equations, we get:

h = tan(60°) * d (for Amanda)

h = tan(30°) * d (for Jeremiah)

Plugging in the given values for d and using a calculator, we can calculate the height of the helicopter for both Amanda and Jeremiah:

h of Amanda = tan(60°) * 4000

h of Amanda ≈ 6928.2 ft (rounded to the nearest foot)

h of Jeremiah = tan(30°) * 4000

h of Jeremiah ≈ 2311.8 ft (rounded to the nearest foot)

So, the height of the helicopter above the ground is approximately 6928.2 ft when viewed by Amanda and approximately 2311.8 ft when viewed by Jeremiah.
