The correct statement is B) A population includes all of the elements from a set of data. This is because a population refers to the totality of subjects we wish to study, whereas a sample is a subset from which we collect data. A statistic is a measure of a sample, and a parameter is a measure of a population.
The question pertains to statistical terminology, specifically the definitions of sample, statistic, population, and parameter. B) A population includes all of the elements from a set of data. This statement is TRUE. A population refers to the entire set of subjects or elements that we are interested in studying. The definition can be applied across various contexts, such as all students in a school, all the birds in a forest, or all the cars produced by a factory.
Conversely, a sample is a subset of the population from which data is actually collected. This is because it is often impractical or impossible to collect data from the entire population. A statistic is a characteristic of a sample, such as the mean or standard deviation, which provides an estimate of the corresponding population parameter. A parameter, therefore, is a characteristic that describes the entire population. For instance, if we calculate the average height of a sample of students from a school, that average is a statistic that estimates the average height of the entire school population—an example of a parameter.
Statement A is incorrect because a measurable characteristic of a population is called a parameter, not a statistic. Statement C is incorrect because multiple samples can be drawn from the same population. Statement D is incorrect because a measurable characteristic of a sample is called a statistic, not a parameter.
In ΔSTU, u = 23 inches, ∠T=158° and ∠U=17°. Find the length of t, to the nearest 10th of an inch.
Answer: t = 29.5 inches
Step-by-step explanation:
Given that the ΔSTU, u = 23 inches, ∠T=158° and ∠U=17°.
We can Find the length of t by using sine rule
t/saint = u/sinU
t/sin158 = 23/sin17
t = sin158 × 23/sin17
t = 29.47 inches
t = 29.5 inches
Answer:

Step-by-step explanation:
What is the length of side s of the square shown below?
The length of side "s" of the square is 3 units, as it is equal to one of the legs of the 45-45-90 right triangle formed by the diagonal of the square.
To find the length of side "s" of the square shown below, we can use trigonometry, specifically the properties of right triangles and the fact that the diagonal divides the square into two congruent 45-45-90 right triangles.
Given information:
The diagonal of the square measures 6 units.
One of the angles at the top of the square is 45 degrees.
Step 1: Recognize the properties of the 45-45-90 triangle:
Since the diagonal divides the square into two congruent right triangles, and one angle is 45 degrees, we have a 45-45-90 triangle. In such a triangle, the two legs (the sides opposite the 45-degree angles) are congruent, and the hypotenuse (the side opposite the 90-degree angle) is √2 times the length of a leg.
Step 2: Use trigonometric ratios:
Let "x" be the length of one leg of the 45-45-90 triangle, which is also equal to side "s" of the square.
From the properties of the 45-45-90 triangle:
x (leg) = s (side of the square)
Hypotenuse = √2 * leg
Given that the diagonal of the square is 6 units, we can relate the diagonal to the legs:
Diagonal = 2 * leg
6 = 2 * x
Now, solve for x (the length of one leg of the triangle and side "s" of the square):
x = 6 / 2 = 3 units
So, the length of side "s" of the square is 3 units.
Therefore, from the given options the correct one is B.

After opening day, theme park attendance has been tracked at a new park in Destin, FL..
Answer:
13.9% marginal
Step-by-step explanation:
The percentage of tickets sold to Seniors can be found as:
[tex]p(s)=\frac{S}{N}\cdot 100[/tex]
where
S is the number of all tickets sold to seniors
N is the total number of tickets sold
By looking at the table, we see that:
S = 32 + 14 + 54 = 100 is the number of tickets sold to seniors
N = 35 + 87 + 62 + 56 + 177 + 205 + 32 + 14 + 54 = 722 is the total number of tickets sold
Therefore, the percentage is:
[tex]p(s)=\frac{100}{722}\cdot 100 =13.9\%[/tex]
The three different types of frequencies are defined as:
- Joint: the frequency of a single category calculated with respect to the total number --> this is not the case
- Marginal: the frequency of an entire row/column over the total --> this is the case
- Conditional: the frequency of a single category over a subset of the total --> this is not the case
So, the correct answer is
13.9% marginal

To simplify the given expression, we can apply the rules of exponents.
First, we raise 3 to the power of 3 and 6 to the power of 6, individually:
3^3 = 27 and 6^6 = 46656.
Next, we multiply these two values together:
27 * 46656 = 1259712.
Now, we raise the result to the power of -3:
1259712^(-3).
To simplify this expression, we can rewrite it as the reciprocal of the base raised to the positive exponent:
(1 / 1259712^3).
This can be further simplified by raising the base to the power of 3:
(1 / (1259712 * 1259712 * 1259712)).
Finally, we can simplify the expression by multiplying the denominators:
1 / (1954890816015872).

Step-by-step explanation:
A cyclist rode at constant speed of 23 mph for 4 hours. Then, she decreased her rate of speed to 16 mph for 5 hours. How far did the cyclist ride in 9 hours?
The cyclist rode a total of 172 miles in 9 hours, covering 92 miles at 23 mph for 4 hours and 80 miles at 16 mph for 5 hours.
Explanation:To find out how far the cyclist rode in 9 hours, we need to calculate the distance covered at each speed and then add those distances together. The cyclist rode at a constant speed of 23 mph for 4 hours and then at a speed of 16 mph for 5 hours.
First, we calculate the distance at 23 mph:
Distance = Speed × Time
Distance at 23 mph = 23 mph × 4 hours = 92 miles
Next, we calculate the distance at 16 mph:
Distance at 16 mph = 16 mph × 5 hours = 80 miles
Now, we add the distances together to get the total distance:
Total Distance = Distance at 23 mph + Distance at 16 mph
Total Distance = 92 miles + 80 miles = 172 miles
Therefore, the cyclist rode a total of 172 miles in 9 hours.

Find the MEAN is this data set ?
And the ABSOLUTE DEVIATION ?
The mean of a dataset is the sum of the elements divided by how many elements are present in the data set.
The sum of the elements in this dataset is
[tex]93+95+102+91+104+93+95+98+97+92+102+96+92+104+100+98=1552[/tex]
And there are 16 elements, so the mean is
[tex]\mu = \dfrac{1552}{16}=97[/tex]
The absolute deviation is computed as follows:
For each term in the dataset, we consider its distance from the mean. In formulas, we compute [tex]|x_i-\mu|[/tex] for every element [tex]x_i[/tex] We take the average of all these terms: [tex]\frac{1}{n}\sum|x_i-\mu|[/tex]So, following the first point, the new dataset is

James cut out four parallelograms, the dimensions of which are shown below. Parallelogram 1 length: 12 in. width: 15 in. diagonal: 20 in. Parallelogram 2 length: 16 in. width: 30 in. diagonal: 34 in. Parallelogram 3 length: 20 in. width: 21 in. diagonal: 29 in. Parallelogram 4 length: 18 in. width: 20 in. diagonal: 26 in. James put the parallelograms together so one vertex from each paper exists on a point, as shown in the circle. 4 parallelograms are put together so that one vertex from each paper exists on a point. Which statement explains whether or not the parallelgrams can be put together so each occupies one-quarter of the area of the circle without overlapping any other pieces? Check all that apply. The quadrilaterals can be placed such that each occupies one-quarter of the circle. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 1 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 2 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 3 do not form right angles. The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 4 do not form right angles.
Answer: The correct options are options 1 and 4.
The quadrilaterals cannot be placed such that each occupies one quarter of the circle because the vertices of parallelogram 1 do not form right angles.
The quadrilaterals cannot be placed such that each occupies one quarter of the circle because the vertices of parallelogram 4 do not form right angles.
Step-by-step explanation: When you have the dimensions of a quadrilateral given along with the diagonal (which is also the hypotenuse) you basically have the quadrilateral divided into two triangles. You can determine if the triangles are going to be right angled or not simply by using the Pythagoras theorem as a test.
Note also that if the angles are right angled, then the quadrilaterals can all be conveniently placed, one in each quarter of the circle without overlapping. This is possible because each quarter of a circle measures 90 degrees.
To test if the angles formed are right angled we shall take the following steps;
Pythagoras theorem states that; AC² = AB² + BC²
Where AC is the longest side (hypotenuse), and AB and BC are the other two sides.
(Quad 1) ------> 20² = 12² + 15²
400 = 144 + 225
400 ≠ 369
Both sides pf the equation are not equal, hence the vertices of parallelogram 1 do not form a right angle.
(Quad 2)------> 34² = 16² + 30²
1156 = 256 + 900
1156 = 1156
Both sides of the equation are equal, hence the vertices of parallelogram 2 forms a right angle
(Quad 3)------> 29² = 20² + 21²
841 = 400 + 441
841 = 841
Both sides of the equation are equal, hence the vertices of parallelogram 3 forms a right angle
(Quad 4)------> 26² = 18² + 20²
676 = 324 + 400
676 ≠ 724
Both sides sides of the equation are not equal, hence the vertices of parallelogram 4 do not form a right angle.
From the results shown above, if the four parallelograms are placed in each of the four corners of the circle, they would definitely overlap because two of them do not form right angles at their vertices.
Answer:
B & E
Step-by-step explanation:
The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 1 do not form right angles.
The quadrilaterals cannot be placed such that each occupies one-quarter of the circle because the vertices of parallelogram 4 do not form right angles.

Lorenzo has a package that weighs 2 pounds.
He wants to check the weight of the package on a scale, but he only has weights that are measured in ounces
Drag the weights into the box that will balance the scale. Each weight can be used once or not at all,
4 oz
10 OZ
12 oz
16 OZ
30 oz
Weights Needed to Balance Scale
Answer:
16 oz, 12 oz, 4 oz
Step-by-step explanation:
Since 1 pound is equal to 16 ounces, and you can only use each weight once or not at all, you can determine how much is needed by simply adding.
2 pounds is equal to 32 ounces.
To achieve 32 ounces, you can use a 16 ounce weight, which will then bring the scale to need 16 ounces.
After this you can youse a 12 ounce weight, which brings it down to 4 ounces.
The last weight needed is the 4 ounce weight which will then level out the balance scale.

The parks department is installing a new picnic area that measures 20 yards by 48 feet.
They are going to cover the new picnic area with square pieces of sod.
If the sod costs $11 per square yard, how much will the parks department pay to completely cover the picnic area with sod?
Answer:
$3520
Step-by-step explanation:
Conversion
To convert feet to yards, we divide the measurement of feet by 3 hence for dimenaion given as 48 ft, it will be 48÷3=16 yards
The area will be given by the product of length and width and since both measurements are given
A=lw
A=16*20=320 yd²
Cost will be 320*11=$3520
Therefore, the department will have to pay $3520 for the work to be completed

D. The x- and y-values are negative,
PLZ HELP!!
Answer:
the answer is C. they are both positive.
Step-by-step explanation:
This is because over the y axis is the first quadrant which is always positive.
Final answer:
Upon reflection over the y-axis, the x-values of the vertices become negative, and the y-values remain positive; hence, option A is correct.
Explanation:
The question asks what is true about the vertices of a triangle located in the first quadrant of the coordinate plane when it is reflected over the y-axis. A reflection over the y-axis in the Cartesian coordinate system would mean that for any point (x, y) on the triangle, the x-coordinate would change its algebraic sign while the y-coordinate would remain the same. This is due to the properties of reflection over an axis where coordinates perpendicular to the axis of reflection change signs, and those parallel remain unchanged.
The correct answer here would be A. The x-values are negative because they are reflected across the y-axis, changing their signs from positive to negative. However, the y-values would remain positive since the triangle is still located in the quadrant above the x-axis, where y-values are positive.
