Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

First 3 miles = flat rate

Subsequent miles = additional rate per mile x

Equation which represents the scenario :

10 + 2.50(x - 3)

If the amount charged by the taxi service for a certain trip is

10 + 2.50(x - 3)

Then. ;

10 = the flat rate charged for the first 3 seconds

2.50 = additional mile charge

x = total trip distance

Hence, (x - 3) = (total trip distance - first 3 miles) = additional miles traveled

a researcher wishes to see if the average number of sick days a worker takes per year is greater than 5. a random sample of 28 workers at a large department store had a mean of . the standard deviation of the population is . is there enough evidence to support the researcher's claim at ? assume that the variable is normally distributed. use the -value method with tables.

Answers

The p-value is greater than 0.05, the researcher would fail to reject the null hypothesis and conclude that there is not enough evidence to support the claim that the average number of sick days taken per year by workers is greater than 5.

It appears that some values are missing in your question, specifically the sample mean and the population standard deviation.

Without these values, I cannot provide a complete answer to your question.

A general idea of how to approach this type of hypothesis test.

To test whether the average number of sick days a worker takes per year is greater than 5, the researcher would need to set up the following hypotheses:

Null hypothesis (H0):

The average number of sick days taken per year by workers is equal to or less than 5.

Alternative hypothesis (Ha):

The average number of sick days taken per year by workers is greater than 5.

The next step would be to collect a random sample of workers and calculate their sample mean and sample standard deviation.

Based on these values, the researcher would then calculate the t-value using the formula:

t = (sample mean - hypothesized population mean) / (sample standard deviation / sqrt(sample size))

The hypothesized population mean in this case is 5, the sample size is 28, and the sample mean and sample standard deviation would be substituted in.

Once the t-value is calculated, the researcher would then use a t-distribution table to find the corresponding p-value based on the degrees of freedom (sample size minus 1) and the level of significance (0.05).

If the p-value is less than 0.05, the researcher would reject the null hypothesis and conclude that there is enough evidence to support the claim that the average number of sick days taken per year by workers is greater than 5.

The specific critical t-value would be based on the degrees of freedom and level of significance.

Answers

The maximum value of f is 12.

Simplex method to maximize the given function is shown below:

Maximize f = 3x + 8y

Subject to 14x + 7y ≤ 56 and 5x + 5y ≤ 80

Step 1: Rewrite the given problem in the standard form by adding slack variables. 14x + 7y + s1 = 56 5x + 5y + s2 = 80

Step 2: Rewrite the objective function such that it contains all the variables on the left. f - 3x - 8y = 0

Step 3: Convert the objective function into an equation by introducing a new variable z. f - 3x - 8y + z = 0

Step 4: Form the initial simplex tableau by placing all the variables and coefficients in a matrix as shown below:

x y s1 s2

RHS 14 7 1 0 56 5 5 0 1 80 -3 -8 0 0 0 1 1 0 0 0

Step 5: Apply the simplex algorithm to find the maximum value of f. We start with the element -3 in row 3 and column 1. We divide all the elements in row 3 by -3.

This gives: x y s1 s2 RHS 14 7 1 0 56 5 5 0 1 80 1.0 2.67 0 0 0 1 1 0 0 0

The smallest positive number is 5/2.

Therefore, we choose the element 5/2 in row 2 and column 2. We divide all the elements in row 2 by 5/2.

This gives: x y s1 s2 RHS 8.57 0.71 1 -1.43 51.43 1 1 0 0 16

The smallest positive number is 1.

Therefore, we choose the element 1 in row 3 and column 2.

We divide all the elements in row 3 by 1. This gives: x y s1 s2 RHS 1.4 0 0.37 -0.2 8.8 1 0 -0.2 0.4 4.0

The optimum solution is x = 4, y = 0, s1 = 0.4, s2 = 0. The maximum value of f is:f = 3x + 8y = 3(4) + 8(0) = 12.

Consider a voted koon structure. The voting can be specified in two different ways:

– As the number k out of the n components that need to function for the system to function.
– As the number k of the n components that need to fail to cause system failure.

In the first case, we often write koon:G (for "good") and in the second case, we write koon:F (for failed).

(a) Determine the number x such that a 2004:G structure corresponds to a xoo4:F structure.
(b) Determine the number x such that a koon:G structure corresponds to a xoon:F structure.

Answers

In reliability engineering, systems can be represented in terms of components that need to function or fail for the system to function or fail.

The notation koon:G represents the number of components that need to function for the system to function, while koon:F represents the number of components that need to fail to cause system failure. The goal is to determine the value of x in different scenarios to understand the system's behavior.

(a) To find the number x such that a 2004:G structure corresponds to a xoo4:F structure, we need to consider that the total number of components is n = 4. In a 2004:G structure, all four components need to function for the system to function. Therefore, we have koon:G = 4. In an xoo4:F structure, all components except x need to fail for the system to fail. In this case, we have koon:F = n - x = 4 - x.

Equating the two expressions, we get 4 - x = 4, which implies x = 0. Therefore, a 2004:G structure corresponds to a 0400:F structure.

(b) To determine the number x such that a koon:G structure corresponds to a xoon:F structure, we have k components that need to function for the system to function. Therefore, koon:G = k. In an xoon:F structure, x components need to fail for the system to fail.

Hence, we have koon:F = x. Equating the two expressions, we get k = x. Therefore, a koon:G structure corresponds to a koon:F structure, where the number of components needed to function for the system to function is the same as the number of components needed to fail for the system to fail.

By understanding these representations, we can analyze system reliability and determine the criticality of individual components within a larger system. This information is valuable in designing robust and resilient systems, as well as identifying potential points of failure and implementing appropriate redundancy or mitigation strategies.

With the full moon at position 3, which two positions experience low tide? 3 and 5 5 and 9 6 and 12 9 and 12

Answers

When the full moon is at position 3, positions 9 and 12 experience low tide.

The correct option is 9 and 12.

The positions of the moon and the sun have an impact on the tides of the Earth's oceans.

What is a tide?

Tides are the regular rise and fall of the sea level due to the gravitational influence of the Moon and the Sun on the Earth. The gravitational pull of the Moon on the Earth produces two tidal bulges, one on the side of the Earth facing the Moon and one on the side opposite the Moon. The Moon's gravitational pull causes high tides in the area of the bulge and low tides elsewhere on the Earth. The tides are affected by the location of the Sun and the Moon as they orbit the Earth.

In order to determine which two positions experience low tide, the Moon's position must be considered.

When the Moon is directly overhead or opposite to the Earth, its gravitational pull has the greatest effect, causing the greatest difference between high and low tides, also known as spring tides.

When the Moon is at a 90-degree angle to the Earth, its gravitational pull is less, causing a smaller difference between high and low tides, also known as neap tides.

In the given case, when the full moon is at position 3, positions 9 and 12 experience low tide.

Thus, the correct option is 9 and 12.

A particle is moving with the given data. Find the position of the particle. a(t) = 2t + 9, S(0) = 2, v(0) = -3. s(t) =

Answers

the velocity function to obtain the position function,  the position of the particle at any given time t can be found using this equation.

To find the position of the particle, we first need to integrate the acceleration function to obtain the velocity function, and then integrate the velocity function to obtain the position function.

Integrating a(t) = 2t + 9 with respect to time, we get v(t) = t^2 + 9t + C, where C is a constant of integration. To find the value of C, we use the initial velocity v(0) = -3, which gives:

-3 = 0^2 + 9(0) + C
C = -3

So the velocity function is v(t) = t^2 + 9t - 3.

Next, we integrate v(t) with respect to time to find the position function. We use the initial position S(0) = 2 to determine the constant of integration.

s(t) = ∫ v(t) dt = ∫ (t^2 + 9t - 3) dt
s(t) = (1/3)t^3 + (9/2)t^2 - 3t + K

Plugging in t = 0 and s(0) = 2, we get:

2 = (1/3)(0)^3 + (9/2)(0)^2 - 3(0) + K
K = 2

So the position function is:

s(t) = (1/3)t^3 + (9/2)t^2 - 3t + 2

Therefore, the position of the particle at any given time t can be found using this equation.

Answers

Using proportions, it is found that 96,734 more obese people were there in evansville than in boulder.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

For Evansville, the proportion of obese people is given by:

189/(311+189) = 189/500.

Hence, out of 358,676 people:

oE = 189/500 x 358676 = 135580.

For Boulder, the proportion is given by:

16/(16 + 109) = 16/125

Hence, out of 303,482 people:

oB = 16/125 x 303482 = 38846.

Hence the difference is given by:

135580 - 38846 = 96734

Answers

Answer:

all positive real numbers and 0

Step-by-step explanation:

The function has a square root in the x value, so this function can't have negative values, because a negative value of x would give a complex number for f(x), and positive values of x gives positive values of f(x).

The function f(x) can be zero, if the value of x is zero:

\(f(0) = \sqrt{0} /2 = 0/2 = 0\)

So the function f(x) can only have positive values and the value 0.

Answers

Answer: (e) (i) To represent the inequalities graphically on a coordinate plane, you can use a scale of 2cm to represent 5 units on each axis. To shade the unwanted regions, you can start by drawing the coordinate plane and labeling the x and y axes. Then, you can graph the inequalities by plotting the lines and shading the regions that do not satisfy the inequalities.

(b) 2x + 3y ≤ 30

This inequality represents a line with the equation 2x + 3y = 30. You can graph this line by plotting a few points and then drawing a straight line through them. The points that are on or below the line satisfy the inequality.

(c) x - 2y ≥ -10

This inequality represents a line with the equation x - 2y = -10. You can graph this line by plotting a few points and then drawing a straight line through them. The points that are on or above the line satisfy the inequality.

(d) y ≤ -2x + 10

This inequality represents a line with the equation y = -2x + 10. You can graph this line by plotting a few points and then drawing a straight line through them. The points that are on or below the line satisfy the inequality.

The set of points that satisfy all three inequalities is the area that is not shaded in the graph.

(ii) To find the maximum number of rabbits the farmer can buy, we need to find the coordinates of the vertex of the feasible region.

The coordinates of the vertex of the feasible region is (x,y) the point where the line 2x+3y=30 and x-2y=-10 intersects.

We can substitute the x-2y=-10 into the 2x+3y=30 equation

2x+3y=30

2x+3y+2y=-10

2x+5y=-10

x=-5y+10

substituting this into one of the equation we have

2(-5y+10)+3y=30

-10y+20+3y=30

-7y=10

y= -10/7

substituting this into x = -5y+10 we have

x = -5(-10/7)+10 = 15

the maximum number of rabbits the farmer can buy is 15

T-tests are statistical tests used to compare the means of two groups and determine if there is a significant difference between them. They are commonly used to assess group equivalence resulting from random assignment.

To determine whether random assignment to groups was effective in creating equivalent groups, researchers commonly use statistical tests like T-tests. T-tests are used to compare the means of two groups and assess whether there is a statistically significant difference between them.

By conducting a T-test on relevant variables between the groups, researchers can evaluate if there are any significant differences that might indicate that random assignment was not successful in creating equivalent groups. If the T-test results in a non-significant p-value, it suggests that there is no significant difference between the groups, providing evidence that random assignment was effective in creating equivalent groups.

Regression analyses, quartiles, and Pearson correlations are not specifically designed to evaluate the effectiveness of random assignment in creating equivalent groups. Regression analyses are used to model relationships between variables, quartiles are used to divide a dataset into equal quarters, and Pearson correlations assess the strength and direction of linear relationships between variables.

While these techniques can be valuable for different research questions and analyses, they are not primarily used for assessing group equivalence resulting from random assignment.

Use substitution to solve for x and y:
[x = -19 -6y
(2x + 3y = -11

Answers

x = -19 -6y 2x + 3y = -11

x+6y = -19 2x + 3y = -11

2(x+6y)= 2(-19) 2x + 3y = -11

2x + 12y = -38 2x + 3y = -11

subtracting both equation

2x + 12y-(2x + 3y) = -38-(-11)

2x+12y-2x-3y = -38+11

9y= -27

y= -3

x= -19-(6×(-3))

x= -19+18

x= -1

x= -1 and y = -3

The slope of a line parallel to y=-3x-4 is?

Answers

Answer:

-3

Step-by-step explanation:

slopes of parallel lines are equal. this equation is in slope intercept form y=mx+b where m (the coefficient of x) is the slope. so this line has a slope of -3 which means a parallel line to this equation also has a slope of -3

Answer:

The slope will be -3

Step-by-step explanation:

y=-3x-4

The line is written in the form

y = mx+b where m is the slope

The slope is -3

Parallel lines have the same slope
