Based on the information, we can answer the questions as follows:
2. This study is an observational study. The researchers did not manipulate any variables or assign participants to groups, they simply observed and recorded the behavior and characteristics of the participants.3. The study shows an association between watching television for at least 2 hours every night and lower energy in the evening. However, correlation does not imply causation. There could be other factors that are affecting both the amount of television watched and energy levels, and it is possible that these factors, rather than television watching, are responsible for the observed lower energy levels.4. This questions asks how an experiment can be set up to determine whether watching television for at least 2 hours every night actually causes lower energy levels in the evening. The answer suggests that a randomized experimental study would need to be conducted, with participants randomly assigned to a group that watches at least 2 hours of television each night, and another group that does not watch as much television. What is a experimental study?An experimental study is a research design in which the researcher manipulates one or more independent variables and measures the effects of those manipulations on one or more dependent variables, while controlling for other potentially relevant factors (known as extraneous variables).
Therefore, he goal of an experimental study is to establish a cause-and-effect relationship between the independent variable(s) and the dependent variable(s).

Determine whether the function is even, odd, or neither.
h(x) = 2x³ + 9x
even
odd
O neither
Describe the symmetry.
O x-axis symmetry
no symmetry
O y-axis symmetry
origin symmetry
Since h(-x) = -h(x), the function is odd.
How to solveThe given function is h(x) = 2x³ + 9x.
To determine whether the function is even, odd, or neither, we need to analyze the behavior of the function when x is replaced by -x:
h(-x) = 2(-x)³ + 9(-x) = -2x³ - 9x.
Since h(-x) = -h(x), the function is odd.
Odd functions have origin symmetry, which means that if you rotate the graph 180 degrees around the origin, it remains unchanged. In other words, the graph has symmetry with respect to the origin, which occurs when the point (x, y) on the graph implies the point (-x, -y) is also on the graph.
So, the function h(x) is odd and has origin symmetry.

Marina is drawing a plan for a new garden. The rectangle plotted in the coordinate plane represents the garden, measured in feet. To surround the garden with a stone path, how many feet of stone does she need? 4 feet 6 feet 10 feet 20 feet
If Mariana needs to surround the garden with a stone-path, then she would need 20 feet of stone, Option (d) is correct.
The "Perimeter" of a rectangle is defined as the "total-length" of the outer boundary.
The length of the rectangle can be calculated as the difference between the x-coordinates of the vertices on the same vertical side.
In this case, the "x-coordinates" of vertices on same vertical side are 4 and -2.
So, the length of the rectangle is = 4 -(-2) = 6 feet.
Similarly, the width of rectangle is calculated as difference between "y-coordinates" of vertices on same horizontal side.
In this case, the "y-coordinates" of vertices on same horizontal side are 1 and -3.
So, the width of the rectangle is = 1 -(-3) = 4 feet,
To surround rectangle with a stone path, Marina need to add length of stone needed for the perimeter of rectangle, which is sum of all four sides.
The perimeter (P) is ⇒ P = 2(length + width),
Substituting the values,
We get,
⇒ P = 2(6 + 4) = 2(10) = 20 feet
Therefore, the correct option is (d).

Graph y=4/7x−2.
Use the line tool and select two points on the line to graph the line.
Answer:
Therefore, the answer is: The graph of the equation is a straight line passing through the points (0, -2), (7, 2), and (-7, -6).
Step-by-step explanation:
The given equation is y = (4/7)x - 2.
To graph this equation, we need to plot points on a coordinate plane. We can do this by choosing values of x and then finding the corresponding values of y using the equation.
Let's choose some values of x and find the corresponding values of y:
When x = 0, y = (4/7)(0) - 2 = -2
When x = 7, y = (4/7)(7) - 2 = 2
When x = -7, y = (4/7)(-7) - 2 = -6
We now have three points: (0, -2), (7, 2), and (-7, -6). We can plot these points on a coordinate plane and draw a line through them to get the graph of the equation.

When comparing the data, which measure of center should be used to determine which location typically has the cooler temperature?
Median, because Sunny Town is symmetric
Mean, because Sunny Town is skewed
Median, because Beach Town is skewed
Mean, because Beach Town is symmetric
Answer:Range, because it measures the difference between the highest and lowest values in a datase........
Step-by-step explanation:
The median should be used to determine which location typically has the cooler temperature, with Beach Town being the location with higher temperatures due to its skewed data.
The measure of center that should be used to determine which location typically has the cooler temperature is the Median, because Beach Town is skewed.
The median is a measure of center that represents the middle value of a data set when it is arranged in ascending or descending order. When comparing the two histograms, Sunny Town's data is symmetric, meaning that it has roughly equal frequencies on both sides of the center. In this case, the median could be a good representation of the typical temperature in Sunny Town.
However, Beach Town's data is skewed, meaning that it is not symmetrical and has a longer tail on one side of the center. This indicates that there are more occurrences of higher temperatures in Beach Town compared to Sunny Town. In skewed data, the mean can be affected by extreme values, making it less reliable as a measure of center. The median, on the other hand, is less influenced by extreme values and can give a better indication of the typical temperature in Beach Town.
Therefore, the median should be used to determine which location typically has the cooler temperature, with Beach Town being the location with higher temperatures due to its skewed data.

after a snowstorm city workers removed an estimated 10000 cubic yards of snow from the downtown area if this snow were apread in an even layer ocer the entire rectangular football field shown below about how many yards deep would the layer of snow be
The 10,000 cubic yards of snow were spread evenly over the rectangular football field, the layer of snow would be approximately 1.56 yards deep.
To determine how many yards deep the layer of snow would be if spread evenly over the rectangular football field, we need to know the volume of the snow and the area of the football field.
First, let's find the area of the football field. Assuming standard dimensions for a football field, we have:
Length = 120 yards
Width = 53.3 yards
Area = Length x Width
Area = 120 yards x 53.3 yards
Area = 6,396 square yards
Now, let's find the volume of the snow. We are given that 10,000 cubic yards of snow were removed from the downtown area, so the volume is:
Volume = 10,000 cubic yards
Finally, to find the depth of the layer of snow, we can divide the volume of the snow by the area of the football field:
Depth = Volume / Area
Depth = 10,000 cubic yards / 6,396 square yards
Depth ≈ 1.56 yards
Therefore, if the 10,000 cubic yards of snow were spread evenly over the rectangular football field, the layer of snow would be approximately 1.56 yards deep.

The probability that a contestant played an electric guitar is 0.8, the probability that a contestant was dressed in sequins is 0.4, and the probability that a contestant played an electric guitar or was dressed in sequins is 0.9.
What is the probability that a randomly chosen contestant played an electric guitar and was dressed in sequins?
By probability, the likelihood that a candidate chosen at random played an electric guitar and wore sequins is 0.3.
explain probability.Using probabilities, one can determine how likely something is to occur.. It is represented by a number between 0 and 1, with 1 denoting a certain event and 0 an impossibility.
For instance, you can get either heads or tails when you flip a coin. There is only one way to get heads and two outcomes, hence the probability of receiving heads is 0.52.
The likelihood that a competitor played an electric guitar is 0.8, the likelihood that they were wearing sequins is 0.4, and the combined likelihood that they both played an electric guitar and wore sequins is 0.91.
The following formula can be used to determine the likelihood that a competitor chosen at random played an electric guitar and wore sequins:
P(A and B) equals P(A) times P(B|A)
where there are two events, A and B.
In this instance, A stands for the competitor who played an electric guitar, and B is for the person who wore sequins.
P(A) is known to equal 0.8. and P(B) = 0.4.
We also know that P(A or B) = 0.9.
Using the following equation to determine the likelihood of two events occurring together:
P(A or B) = P(A) + P(B) - P(A and B)
we can find P(A and B):
P(A and B)
= 0.8 + 0.4 - 0.9
= 0.3

LOT OF POINTS AND BRAINLIEST IF YOU'RE RIGHT:
Public opinion in the large city of Hillwood is that 62 percent of the residents are in favor of increasing taxes to fund afterschool programs and 38 percent are against the increase. What is the approximate probability that more than 180 of the residents surveyed will be against increasing taxes if a random sample of 450 residents are surveyed? (4 points)
Answer:
0.16%
Step-by-step explanation:
Imagine you are a politician who wants to increase taxes in your city. You decide to conduct a survey among 450 residents to see how many of them are against your proposal. You know that the probability of finding someone who is against increasing taxes is 0.38. You hope that the survey will show that most people support your idea, or at least that the opposition is not too strong. However, when you get the results, you are shocked to see that more than 180 people are against increasing taxes. How unlucky are you? Well, let's do some math. This is a binomial probability problem. The probability of success (being against increasing taxes) is p = 0.38 and the number of trials (residents surveyed) is n = 450. The question asks for the probability of more than 180 successes, which is equivalent to the probability of at least 181 successes. Using a binomial calculator, the answer is approximately 0.0016 or 0.16%. That means that there is only a 0.16% chance of getting at least 181 people against increasing taxes in a sample of 450 residents. That's very rare and unlucky indeed! You might want to reconsider your proposal or find a better way to convince people that paying more taxes is good for them.

Part B: Explain, in words, how to create the graphical display you chose in Part A. Be sure to include a title, axis label(s), scale for axis if needed, and a clear process of how to graph the data. (6 points)
The resulting histogram would show the distribution of the grades on the exam, with the bins and frequency of data points clearly displayed. The title, axis labels, and scales would provide context for the graph and make it easy to interpret the data.
What is graph?In mathematics and computer science, a graph is a collection of points, called vertices or nodes, that are connected by lines, called edges or arcs. Graphs can be used to model and analyze relationships between objects or data, such as social networks, transportation systems, or web pages.
Here,
Part A:
The best graphical representation to display the given data is a histogram. A histogram is a bar graph-like representation of data that divides the data into intervals or bins and shows the frequency of each interval. Histograms are appropriate for displaying continuous data, which the grades on the exam can be considered as, and can also show the distribution of the data.
Part B:
To create a histogram of the given data, follow these steps:
Choose the number of bins or intervals. In this case, we can choose a reasonable number of bins, such as 6-8, to display the distribution of the grades.
Determine the range of the data. The lowest grade is 60 and the highest is 99, so the range is 99-60 = 39.
Calculate the bin size. The bin size is calculated by dividing the range by the number of bins. For example, if we choose 6 bins, the bin size would be 39/6 ≈ 6.5. Since it is difficult to have bins that are fractions of a point, we can round the bin size up to the nearest whole number to get a bin size of 7.
Create the bins. Starting from the lowest grade, create intervals or bins of size 7 that cover the range of the data. For example, the first bin would be 60-66, the second bin would be 67-73, and so on.
Count the frequency of data points that fall into each bin. For example, there are 2 data points in the first bin, 3 data points in the second bin, and so on.
Draw the histogram. On the horizontal axis, label and scale the bins. On the vertical axis, label and scale the frequency of data points in each bin. Draw a rectangle above each bin with a height equal to the frequency of data points in that bin.

The probability that the spinner lands on an even number or a number greater than 10 is 11/18.
There are two cases where the spinner can land on an even number or a number greater than 10:
Case 1: The spinner lands on an even number.
There are 9 even numbers on the spinner: 2, 4, 6, 8, 10, 12, 14, 16, and 18. The probability of the spinner landing on an even number is 9/18 = 1/2.
Case 2: The spinner lands on a number greater than 10.
There are 7 numbers greater than 10 on the spinner: 11, 12, 13, 14, 15, 16, and 18. The probability of the spinner landing on a number greater than 10 is 7/18.
To find the probability of either event occurring, we add the probabilities of the two cases and subtract the probability of both occurring simultaneously (since the numbers 12, 14, and 16 are even and greater than 10). Therefore, the probability of the spinner landing on an even number or a number greater than 10 is:
(1/2) + (7/18) - (3/18) = 11/18
Thus, the probability that the spinner lands on an even number or a number greater than 10 is 11/18.

If you buy a ticket, you can expect to make a profit of approximately $0.96 on average.
To calculate the expected profit, we need to consider the probability of winning each prize and the value of each prize.
The probability of winning each prize can be calculated by dividing the number of winning tickets by the total number of tickets. There is 1 winning ticket for each prize, so the probability of winning each prize is:
$240 prize: 1/250
$130 prize: 1/250
$120 prize: 1/250
$70 prize: 1/250
The value of each prize is already given, so we can multiply the probability of winning each prize by its value and sum the results to find the expected profit:
Expected profit = (1/250 x $240) + (1/250 x $130) + (1/250 x $120) + (1/250 x $70) - ($16)
Expected profit = $0.96

Define matricesMatrices are a type of mathematical object that consists of a rectangular array of numbers or other mathematical objects, such as variables, functions, or even other matrices. Matrices are widely used in mathematics, science, engineering, computer graphics, and other fields to represent and manipulate data, perform transformations, and solve systems of equations.
A matrix can be represented using a set of ordered pairs, where each pair represents a specific element of the matrix, and the position of the element is determined by its row and column indices. For example, a 3x3 matrix can be represented as:
| a11 a12 a13 |
| a21 a22 a23 |
| a31 a32 a33 |
Given matrix;
A=[tex]\left[\begin{array}{ccc}-1&-2 \\2&2 \\ \end{array}\right][/tex]
B=[tex]\left[\begin{array}{ccc}-6&5 \\2&-1 \\ \end{array}\right][/tex]
C=[tex]\left[\begin{array}{ccc}-3&1 \\2&0 \\ \end{array}\right][/tex]
Solving the equation
(A-4B)X=C
[tex]\left[\begin{array}{ccc}-1&-2 \\2&2 \\ \end{array}\right][/tex]- 4 [tex]\left[\begin{array}{ccc}-6&5 \\2&-1 \\ \end{array}\right][/tex]X=[tex]\left[\begin{array}{ccc}-3&1 \\2&0 \\ \end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}23&-22 \\-6&6 \\ \end{array}\right][/tex] X=[tex]\left[\begin{array}{ccc}-3&1 \\2&0 \\ \end{array}\right][/tex]
Taking the inverse and multiplying it with RHS, we get
X=[tex]\left[\begin{array}{ccc}-31/135 & 1/45 \\14/135&1/45 \\ \end{array}\right][/tex]

a cube is made up of 27 equal sized cubes. if all faces of the large cube are painted, how many small cubes will not have any paint on any of their faces?
If a large cube is made up of 27 equal-sized smaller cubes, and all faces of the large cube are painted, then the cubes on the interior of the large cube will not have any paint on any of their faces.
The large cube consists of 27 smaller cubes arranged in a 3x3x3 pattern. The smaller cubes on the exterior faces of the large cube will have some of their faces painted, while the smaller cubes on the interior will not have any of their faces painted.
To calculate the number of smaller cubes that will not have any paint on any of their faces, we need to subtract the smaller cubes on the exterior faces from the total number of smaller cubes in the large cube.
The number of smaller cubes on the exterior faces of the large cube can be calculated as follows:
There are 9 smaller cubes on each of the six faces of the large cube (3x3=9), for a total of 54 smaller cubes on the exterior faces.
So, the total number of smaller cubes in the large cube is 27, and the number of smaller cubes on the exterior faces is 54. Therefore, the number of smaller cubes that will not have any paint on any of their faces is:
27 - 54 = -27
Since we cannot have a negative number of cubes, the correct answer is 0. There will be 0 smaller cubes that will not have any paint on any of their faces.

A deck of standard playing cards holds 52 unique cards.
36 of these cards are numbered cards (numbered 2-9), 4
of these cards are aces, and 12 of these cards are face
cards (jack, queen, and king). If you play a card game and
draw half of the face cards, one ace, and one fourth of the
numbered cards, how many cards do you have? How
many of each card type of card do you have? Cite
evidence from the problem.
Answer:
Based on the information in the problem, you would have a total of 16 cards, with 6 being face cards, 1 being an ace, and 9 being numbered cards.
Step-by-step explanation:
According to the issue:
The deck contains 52 distinct cards.
There are 36 numbered cards ranging from 2 to 9.
There are four aces in the deck.
There are 12 face cards (including the jack, queen, and king).
If you draw half of the face cards, one ace, and one-fourth of the numbered cards, you will get the following:
Face cards in half: 1/2 * 12 = 6 face cards
1 ace: 1 ace
One-fourth of a deck of numbered cards: 1/4 * 36 = 9 decks of numbered cards
When you add these up, you get a total of 6 + 1 + 9 = 16 cards.
Based on the information in the problem, you would have a total of 16 cards, with 6 being face cards, 1 being an ace, and 9 being numbered cards.

x2+y2−2x−6y−26=0
x squared plus y squared minus 2 x minus 6 y minus 26 equals 0
x2+y2+2x+6y−26=0
x squared plus y squared plus 2 x plus 6 y minus 26 equals 0
x² + y² + 2x + 6y + 4 = 0
x, ² +, y, ² + 2, x, + 6, y, + 4 = 0
x2+y2−2x−6y+4=0
x squared plus y squared minus 2 x minus 6 y plus 4 equals 0
The equation of this circle in general form is: (x - 1)^2 + (y - 3)^2 = 36
How to find the equation of the circle in general formTo find the equation of a circle in general form, we need to complete the square for both x and y terms.
x^2 + y^2 - 2x - 6y - 26 = 0
First, we will complete the square for x terms:
x^2 - 2x + y^2 - 6y - 26 = 0
(x - 1)^2 - 1 + y^2 - 6y - 26 = 0
(x - 1)^2 + y^2 = 27
Now, we will complete the square for y terms:
(x - 1)^2 + (y - 3)^2 = 36
Therefore, the equation of this circle in general form is: (x - 1)^2 + (y - 3)^2 = 36
