The possible locations of the vertice D such that the trapezoid ABCD is created are;

(3, 2), (3, 7)

A trapezoid is a quadrilateral with one pair of parallel sides.

The location of the vertex D is between vertices A and C

When AD is parallel to BC, we get;

Slope of AD = Slope of BC

Slope of BC = (-1 - 1)/(-1 - (-5)) = -2/4 = -1/2

The point, D, obtained from point A is therefore;

-(1/2) = (y - 5)/(x - (-3)) = (y - 5)/(x + 3)

-(1/2) = (y - 5)/(x + 3)

2·y - 10 = -x - 3

2·y = -x - 3 + 10 = -x + 7

2·y = -x + 7

y = -x/2 + 7/2 = -x/2 + 3.5

y = -x/2 + 3.5

The possible points are therefore;

When x = 3, y = -3/2 + 3.5 = 2

When CD is parallel to AB, we get;

Slope of AB = (5 - 1)/(-3 - (-5)) = 4/2 = 2

The slope of CD is therefore; (y - (-1))/(x - (-1)) = 2

(y + 1)/(x + 1) = 2

y + 1 = 2 × (x + 1)

y = 2·x + 2 - 1 = 2·x + 1

y = 2·x + 1

The possible location of point D is therefore; When x = 3, y = 2×3 + 1 = 7

3. The test result provides significant evidence that the company is under-filling their containers.

4. Based on the hypothesis test, it can be concluded that the grip adjustment had a significant impact on Marco's throwing distance.

3. Null hypothesis (H0): μ = 12 (the true mean filling volume is equal to 12 oz)

Alternative hypothesis (H1): μ < 12 (the true mean filling volume is less than 12 oz)

We'll use a one-sample t-test since we have the sample mean, the population standard deviation, and a sample size less than 30.

The test statistic can be calculated as:

Plugging in the values:

sample mean (X) = 11.85

population mean (μ) = 12

population standard deviation (σ) = 0.45

sample size (n) = 36

t = (11.85 - 12) / (0.45 / √36)

t = -0.15 / (0.45 / 6)

t = -0.15 / 0.075

t = -2 (rounded to two decimal places)

To find the p-value associated with this test statistic, we'll use a t-distribution table or statistical software.

With a sample size of 36 and a significance level of 5%, the degrees of freedom are 35.

Looking up the p-value for a t-score of -2 with 35 degrees of freedom, we find that it is approximately 0.026.

Since the p-value (0.026) is less than the significance level of 0.05, we reject the null hypothesis.

There is significant evidence to suggest that the company is under-filling their soda cans.

4.

Null hypothesis (H0): μ = 42 (the true mean throwing distance is equal to 42 yards)

Alternative hypothesis (H1): μ > 42 (the true mean throwing distance is greater than 42 yards)

We'll use a one-sample t-test since we have the sample mean, the population standard deviation, and a sample size of 50.

The test statistic can be calculated as:

Plugging in the values:

sample mean (X) = 44

population mean (μ) = 42

population standard deviation (σ) = 4

sample size (n) = 50

t = (44 - 42) / (4 / √50)

t = 3.53

To find the p-value associated with this test statistic, we'll use a t-distribution table.

With a sample size of 50 and a significance level of 0.01, the degrees of freedom are 49.

Looking up the p-value for a t-score of 3.53 with 49 degrees of freedom, we find that it is very close to 0 (essentially 0).

Since the p-value is less than the significance level of 0.01, we reject the null hypothesis.

Answer:

The plane travels at a speed of 66 miles per hour without wind.

Step-by-step explanation:

Tyler trip has to stage, the first one where he went against the wind and the second where he returned with the wind. We know that the wind speed is 6 mph, if we attribute the variable "x" to the speed of the plane without wind, then on the first stage of its trip the total speed relative to the ground was "x - 6", while on the return trip it was "x + 6". We also know that the distance between the trips was the same 4320 miles, but the second stage was 12 hours faster. We will use the average speed formula to solve this problem, this is shown below:

\(\text{speed} = \frac{\text{distance}}{\text{time}}\)

For the first trip the speed was:

\(x - 6 = \frac{4320}{\text{time}_1}\\\\\text{time}_1 = \frac{4320}{x - 6}\)

For the second trip the speed was:

\(x + 6 = \frac{4320}{\text{time}_2}\\\\\text{time}_2 = \frac{4320}{x + 6}\)

Since the time for the second trip was 12 hours less, then if we add 12 to the second equation it should be equal to the first, so:

\(time_2 + 12 = time_1\)

\(\frac{4320}{x + 6} +12 = \frac{4320}{x - 6}\\\frac{4320}{x+ 6} - \frac{4320}{x - 6} = -12\\\frac{4320*(x - 6) - 4320*(x + 6)}{x^2 - 36} = -12\\4320*x - 25920 - 4320*x - 25920 = -12*x^2+ 432\\-51840 = -12*x^2 +432\\12*x^2 =51840 + 432\\x^2 = \frac{52272}{12}\\x^2 = 4356\\x = 66\)

The plane travels at a speed of 66 miles per hour.

What is inequality?

An inequality in mathematics depicts the connection between two values in an algebraic statement that are not equal. One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.

5(x – 2)(x + 4) > 0

First we solve for x, we replace the inequality sign by = sign

5(x – 2)(x + 4) = 0

Divide both sides by 5

(x – 2)(x + 4) = 0

Now we set each factor =0  and solve for x

x-2 =0 , so x= 2

x+4 =0, so x= -4

Now we use number line and make three intervals

Question:

What is the solution set to the inequality 5(x – 2)(x + 4) > 0?

Answer:

y = 3x - 5

Step-by-step explanation:

1. Since we know the equation of a line in slope-intercept form is y = mx + b, we have to solve for the variable, y.

2. (Solving)

Step 1: Add -6x to both sides

Step 2: Divide both sides by -2.

Therefore, the slope-intercept form of 6x - 2y = 10 is equal to y = 3x - 5.

The slope - intercept form of the equation is, y = 3x - 5.

What is slope - intercept from of the equation?

y=mx+b, where m is the slope and b is the y-intercept, is the slope intercept form. The graph of the linear equation can be drawn on the x-y coordinate plane using this form of the equation.

The given equation is,  6x - 2y = 10
Since we are aware that the slope-intercept form equation for a line is y = mx + b, we must find the value of the variable y.

Consider, the equation 6x - 2y = 10

Subtract 6x from both sides,

6x - 2y - 6x = 10 - 6x

-2y = 10 - 6x

Divide both sides by 2,

\(\frac{-2y}{2} = \frac{10 - 6x}{2} \\-y = 5 - 3x\)

Multiply both sides by -1.

y = -5 + 3x

y = 3x - 5

Therefore, the equation of a line into slope - intercept form is, y = 3x - 5.

Step-by-step explanation:

The number of people that attended the game in each cost category is Faculty: 7,000,Alumni: 18,000,Public: 18,000,Veterans: 4,000

To determine the number of people that attended the game in each cost category,  to consider the given information and set up a system of equations to solve for the unknowns. Let's break down the problem step by step.

Let's denote the number of people in each cost category as follows:

Faculty: F

Alumni: A

Public: P

Veterans: V

The number of alumni is 11,000 more than the faculty, so we have the equation:

A = F + 11,000

The number of public plus alumni together was 10 times the number of veterans, so  the equation:

P + A = 10V

The number of faculty plus alumni together was the same as the number of veterans, so we have the equation:

F + A = V

The total number of people attending the game is the sum of the people in each category, so  the equation:

F + A + P + V = 100,000

Now, use these equations to solve for the unknowns.

First, substitute equation 1 into equations 2 and 3:

P + (F + 11,000) = 10V

F + (F + 11,000) = V

Simplify these equations:

P + F + 11,000 = 10V

2F + 11,000 = V

Next, substitute these equations into equation 4:

F + (F + 11,000) + P + (2F + 11,000) = 100,000

Simplify and combine like terms:

4F + 22,000 + P = 100,000

Subtract 22,000 from both sides:

4F + P = 78,000

Now a system of two equations:

P + F + 11,000 = 10V

4F + P = 78,000

solve this system of equations to find the values of F, P, and V.

By solving the system,

F = 7,000

P = 18,000

V = 4,000

Finally, substitute these values back into equation 1 to find the value of A:

A = F + 11,000 = 7,000 + 11,000 = 18,000
