Do these data (Mod2-2Commercials (Links to an external site.)Links to an external site.) allow us to infer that the mean number of commercials watched during the game is different from 16? Assume the level of significance is 10%.

Answers

Answer 1

No, the data provided in the link does not allow us to infer that the mean number of commercials watched during the game is different from 16.

To test the hypothesis that the mean number of commercials watched is different from 16, we would need to perform a statistical hypothesis test. The level of significance (10%) would be used to determine the critical value(s) for the test statistic, which would then be used to make a decision about the null hypothesis (that the mean number of commercials watched is equal to 16).

Without the results of such a test, it is not possible to make a conclusion about the difference between the mean number of commercials watched and 16.

six friends met for a book club at a local coffee shop. Each person ordered a small cup of coffee and a muffin. The total for the order, including taxes, was $38.10, if the cost of a small coffee is $3.79 after taxes find the cost of one muffin after taxes
Please help me

Answers

The cost of one muffin after taxes is $2.56. The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

For all the real numbers, there are four basic mathematical operations which are:

1. Addition(‘+’) wherein the sum of the numbers is obtained.

2. Subtraction(‘-’) wherein the difference of the numbers is obtained.

3. Multiplication(‘×’) wherein the product of the numbers is obtained.

4. Division(‘÷’) wherein the quotient of the numbers is obtained.

Let cost of one muffin after taxes be 'x'

We are given that there were six friends and each person ordered a small cup of coffee and a muffin.

The total for the order, including taxes, was $38.10

Also, the cost of a small coffee is $3.79 after taxes.

So, we get

⇒ 6(3.79 + x) = 38.10

⇒ 22.74 + 6x = 38.10

⇒ 6x = 15.36

x = $2.56

Hence, the cost of one muffin after taxes is $2.56.

Answers

Based on the data displayed in the histogram, the percentage of students who study 2 or more hours for the midterm is 88%.

A histogram is a graphical representation of data that shows the distribution of a dataset. It is used to show the frequency or the relative frequency of different values within a set of data. It is a bar chart that displays the data in a continuous format, with the bars touching each other.

Based on the histogram, the number of students studying 2 or more hours for the exam are:

= 9 + 6 + 3 + 2 + 1 + 1

= 22 students

While the total number of students studying is :

= 3 + 9 + 6 + 3 + 2 + 1 + 1

= 25 students

The percentage of students study to or more hours can be determined by dividing the number of students studying 2 or more hours with the total number of students studying multiply by 100.

percentage = 22/25 x 100

percentage = 0.88 x 100

percentage = 88%

A ball is thrown from an initial height of 2 meters with an initial upward velocity of 5 m/s.
h=2+5t-5t^2
The ball's height of (in meters) after seconds is given by the following. Find all values of for which the ball's height is 3 meters.

Answers

Answer: The height of the ball (in meters) after t seconds is given by the equation h = 2 + 5t - 5t^2. We can use this equation to find the values of t for which the ball's height is 3 meters.

We need to find the values of t that make h = 3, so we can substitute 3 for h in the equation:

3 = 2 + 5t - 5t^2

Then we can solve for t by moving all the terms to one side of the equation and factoring it:

-5t^2 + 5t - 1 = 0

And we can use the quadratic formula to find the solutions of this equation:

t = (5 +/- sqrt(5^2 - 4*(-1)(-1)))/ 2(-1)

t = (5 +/- sqrt(25 + 4))/ -2

t = (5 +/- sqrt(29))/ -2

The solutions of this equation are t = (5 +/- sqrt(29))/ -2

Since the time, t, is a real value the square root of 29 should be positive.

The values of t for which the ball's height is 3 meters are not real values, so there's no time when the ball's height is 3 meters.

In the field of machine learning, specifically the problem of statistical classification (in unsupervised learning, it is typically referred to as a matching matrix), a confusion matrix, also known as an error matrix, is a specific table structure that enables visualizing the performance of an algorithm.

The literature describes both iterations of the matrix, where each row represents instances in an actual class and each column represents instances in a predicted class. Since it is straightforward to tell whether the system is combining two classes, the name was chosen (i.e. commonly mislabeling one as another).

accuracy is given by the formula :

Accuracy(%) = (true positive + true negative)/(positive + negative)

Here TP true positive =10

and TN true negative is 8.2

hence accuracy = (10+8.2) / (1+0)  %

Accuracy = 10.82%

Answers

it would take 29.5 hours the second airplane to overtake the first.

What is Speed?

speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.

Given, Two airplanes leave Philadelphia for Rochester. The first airplane to leave travels at an average speed of 590 kilometers per hour. The second airplane, which leaves 3 hours later, travels at an average speed of 650 kilometers per hour.

So, in 3 hours first airplane will reach at;

Distance = speed *time

Distance = 590 * 3

Distance travels by first airplane in 3 hours will be = 1770 km

Since, Relative speed of given two planes = 650 - 590

Relative speed of given two planes = 60 km/hour

To reach 1770 km it would take  = 1770/60 hours

Thus,

To reach 1770 km it would take  = 29.5 hours

Based on the information, we can infer that of the 250 adults surveyed, 190 wanted the park to be expanded and 60 did not want the park to be expanded.

How to complete the table?

To complete the table we must take into account the available information. In this case, they are only referring to the adults who wanted the park to be expanded:

40 non-parent adults wanted it expanded.150 adult parents wanted it expanded.

40 + 150 = 190

According to the above, if we add these two values we would have a group of 190 adults who want the park to be expanded. So the number of adults who do not want the park to be expanded would be 60.

250 - 190 = 60

Finally, if there are 60 people who do not want the park to be expanded, we can infer that there may be 30 who are parents and 30 who are not parents.

A child is sitting at the edge of a merry-go-round that has a 3m radius. If the merry-go-
round rotates through 120 degrees, how far does the child end up from his starting
point. Note that you are trying to find the straight line distance from the starting point to
the ending point, not the distance around the circle that the child traveled.

Answers

Answer: To find the distance the child travels, we can use the arc length formula: s = r * θ, where s is the arc length, r is the radius of the circle, and θ is the angle of rotation in radians. Since the merry-go-round has a radius of 3m and rotates through 120 degrees, we can convert the angle to radians by multiplying by pi/180.

120 degrees * pi/180 = 2pi/3 radians

Now we can plug in the values into the arc length formula:

s = r * θ

s = 3 * (2pi/3)

s = 2pi

The distance the child travels is 2pi meters, which is the circumference of the circle.

Suppose that business travelers and vacationers have the following demand for airline tickets from New York to Boston: (1st column) Price (2nd column) Quantity Demanded by Business Travelers (3rd column) Quantity Demanded by Vacationers (Dollars) (Tickets) (Tickets) 150 2,100 1,000 200 2,000 800 250 1,900 600 300 1,800 400 As the price of tickets rises from $250 to $300, the price elasticity of demand for business travelers is 0. 30, and the price elasticity of demand for vacationers is 2. 20, using the midpoint method. Therefore, the demand for airline tickets in this price range is more elastic for vacationers because business travelers are less sensitive to changes in price FILL IN THE BLANK During , _______ _______ an organism emits operant behavior based upon its genetic endowment; the ____________ produces and effect that increases or decreases the frequency of the response in a given situation. this image is from an 1884 issue of frank leslie's illustrated newspaper. what message is the muckraking artist of this image attempting to convey about the u.s. city and its government?
