What is the difference between census and statistics?
In statistics the sampling method is collecting data based on sample of people who represent a population, whereas the census method involves studying each and every member of the population.
What is statistics?
The gathering, characterization, analysis, and drawing of inferences from quantitative data are all tasks that fall under the purview of statistics, a subfield of applied mathematics. Probability theory, linear algebra, and differential and integral calculus play major roles in the mathematical theories underlying statistics.
The differences between census and sampling method is -
The investigator gathers data using the census method, which asks questions about every component of the population.
The investigator gathers data using the sampling method by selecting a sample of the objects that represent the entire population.
The Census Method of Collecting Data is appropriate when the area under inquiry is rather small. The sampling method is preferred when the investigation region is large.
The Census Method requires more time to gather data. The sampling method requires less time to gather data.
Generally speaking, the Census Method is more accurate than the Sampling Method. This accuracy can be attributed to the Census Method's inclusion of a study of every component of the population. The sampling approach has a lower level of accuracy because it examines a smaller sample of the population. However, since there are fewer elements in the sampling method, errors are simple to find and eliminate. Consequently, if that's the case, the sampling method gives more accuracy than census method.
Therefore, the differences for census and sampling method are pointed out.

A = 6,013.53( 1 + 0.0185/4)^4 *10
A = $ 7233
6) A = P(1 + r/n)^nt
6,520.02 = 4,848(1 + r/2)^6 * 2
6,520.02/ 4,848 = (1 + r/2)^6 * 2
1.34 = (1 + r/2)^12

A grasshopper starts jumping forward on the real axis, starting at 0 in the positive direction.
Her jump sizes are independent, each has exponential distribution with mean 2 units.
(a) We have to determine the probability that the number of forward jumps it takes her to jump over 9 for the first time (in forward direction), is exactly 4.
P(k = 0) = [tex]\frac{2^{0}e^{-2}}{0!}[/tex] = 0.1353
P(k = 1) = [tex]\frac{2^{1}e^{-2}}{1!}[/tex] = 0.2706
P(k = 2) = [tex]\frac{2^{2}e^{-2}}{2!}[/tex] = 0.2706

P(k = 4) = [tex]\frac{2^{4}e^{-2}}{4!}[/tex] = 0.0902
The Probability = P(k = 0) + P(k = 1) + P(k = 2) + P(k = 3) + P(k = 4)
The Probability = 0.1353 + 0.2706 + 0.2706 + 0.1804 + 0.0902
The Probability = 0.9471
(b) We have to determine the probability that the number of backward jumps N it takes her to jump over 9 for the first time (in backward direction), is exactly 4.
P(k = 0) = [tex]\frac{1^{0}e^{-1}}{0!}[/tex] = 0.3678
P(k = 1) = [tex]\frac{1^{1}e^{-1}}{1!}[/tex] = 0.3678

The area of the region outside the doghouse that skipper can reach is 3(pi)^2 yards.
This problem is based on the area of sectors. Now, we know that a sector is a pie-shaped part of a circle made of the arc along with its two radii.
The image which correctly explains the situation in the problem is attached.
From the figure, we can see that the spot can be located anywhere in the two sectors of 120 and 60 degrees each respectively. Now, these radii are respectively of 2 and 1 yards.
Area of one sector of 120 degrees = 120/360 π (2)^2 since radius is 2 yards.
So, area of two sectors is 2 x 120/360 π (2)^2 = 8π /3 square yards.
Similarly, Area of the two 60 degrees sectors is -
2 x 60/360 π (2)^2 = π /3 sq. yards.

in terms of m1 , m2 , and g , find the acceleration of the first block in the figure (figure 1). there is no friction anywhere in the system.
The first block's acceleration is inversely proportional to its mass and directly proportional to the mass difference between the two blocks.
What is the speed increase?Without being aware of the precise values of m1, m2, and g, it is impossible to calculate the acceleration of the first block.
Newton's second rule of motion, which states that the net force on an object is equal to its mass times its acceleration, can be used to calculate the acceleration of the first block in the illustration.
Let's call the first block's acceleration "a." The difference between the tension force in the rope connecting the two blocks and the force of gravity can be used to calculate the net force exerted on the first block.
The rope's tension force is generated by:
T = m2 × g
The first block is subject to the following gravitational force:
Fg = m1 × g
The difference between these two forces is the net force exerted on the first block:
Fnet = T - Fg = (m2 - m1) × g = m2 × g - m1 × g
In light of Newton's second law, we can say:
Fnet = a × m1
(m2 - m1) × g = m1 × a
When calculating acceleration, we obtain:
a = (m2 - m1) × g / m1
As a result, the first block's acceleration is inversely proportional to its mass and directly proportional to the mass difference between the two blocks.

7 = a × 2 + b × 0 + c × 1, 7 = a × 0 + b × 4 + c × 1, 13 = a × 3 + b × 4 + c × 10 are the first vector is a linear combination of the other vectors.
What do you mean by Linear combination?In linear algebra, a linear combination is an expression formed by multiplying each element of a set of vectors by a scalar (a real or complex number) and then adding the results. The scalars are called coefficients and the vectors are called terms.
A linear combination can be written as a sum of the form:
a1 × v1 + a2 × v2 + ... + an × vn
where a1, a2, ..., an are the coefficients and v1, v2, ..., vn are the vectors. The result of the linear combination is also a vector, which can be thought of as a combination of the original vectors, weighted by the coefficients.
Linear combinations are used in many applications, including solving systems of linear equations, finding eigenvectors and eigenvalues, and representing a vector as a combination of basis vectors in a vector space.
(a) To determine whether the first vector is a linear combination of the other vectors, we can write a system of equations and solve for the coefficients. If the coefficients exist and are unique, then the first vector is a linear combination of the other vectors. If the coefficients do not exist or are not unique, then the first vector is not a linear combination of the other vectors.
-3 = a × 1 + b × 2 + c × -1
3 = a × -1 + b × 1 + c × 2
7 = a × 2 + b × 0 + c × 1
We can solve this system of equations using methods such as Gaussian elimination or matrix inversion to obtain the coefficients: a = -2, b = -1, c = 4
Therefore, the first vector is a linear combination of the other vectors.
(b) Following the same procedure, we can write a system of equations and solve for the coefficients:
-2 = a × 1 + b × 2 + c × -2
11 = a × -1 + b × 1 + c × 4
7 = a × 0 + b × 4 + c × 1
We can solve this system of equations to obtain the coefficients: a = 3, b = -2, c = 2
Therefore, the first vector is a linear combination of the other vectors.
(c) Using the same procedure, we can write a system of equations and solve for the coefficients:
2 = a × 1 + b × -1 + c × 1
7 = a × 2 + b × 2 + c × 6
13 = a × 3 + b × 4 + c × 10
We can solve this system of equations, but it will have no solution, meaning the coefficients do not exist.
Therefore, the first vector is not a linear combination of the other vectors.

fresh first grocery store purchases bread at $1 per loaf and sells it at $1.50 a loaf. any unsold bread is fed to the geese at a local pond. what is the decision rule?
The decision rule for Fresh First Grocery Store is to sell the bread at $1.50 per loaf if they can, otherwise they will feed it to the geese.
Fresh First Grocery Store purchases bread for $1 per loaf and sells it for $1.50 per loaf. This means that for every loaf of bread they sell, they will make a profit of $0.50. The decision rule for the grocery store is to sell the bread if they can, as this will result in a profit.
However, if they are unable to sell the bread, they have decided to feed it to the geese at a local pond. This decision is likely based on the idea that it is better to give the unsold bread to the geese rather than throw it away, as it will be put to good use and not go to waste.
In conclusion, the decision rule for Fresh First Grocery Store is to sell the bread at $1.50 per loaf if they can, otherwise they will feed it to the geese. This decision takes into account both the desire to make a profit and the desire to avoid waste and put unsold bread to good use.

When graphing a function, what is meant by the input and output values?
When graphing a function, the input values are the independent variable(s) and the output values are the dependent variable(s).
A graph is a visual representation of a function that helps to understand the relationship between the input and output values of the function. In a graph, the horizontal axis represents the input values, and the vertical axis represents the output values. Each point on the graph represents a single pair of input and output values, and the entire graph represents the entire set of input and output values of the function.
When graphing a function, the input values are the independent variable(s) and the output values are the dependent variable(s).
For example, in the case of a simple linear function such as y = f(x) = 5x + 4, the input value is x, and the output value is y. To create the graph of this function, you would plot a set of ordered pairs (x, y), where x is the input value and y is the corresponding output value.
Similarly, in the case of a multi-variable function such as z = f(x, y), the input values are x and y, and the output value is z. To create the graph of this function, you would plot a set of ordered triples (x, y, z), where x and y are the input values and z is the corresponding output value.

consider the following metabolic rates: 1772 1666 1362 1460 1867 1439 1614 suppose the number 1772 was accidentally changed to 1972. how would this change the value of the median? group of answer choices increase median would not change the median decrease median
The answer is the median would not change.
The median of a set of numbers is the middle value when the numbers are arranged in order. It is not affected by outliers or extreme values as much as the mean is.
If the number 1772 was accidentally changed to 1972, this would increase the value of the number and it would become an outlier in the set. To calculate the median, we need to arrange the numbers in order. The new set would be:
1362 1439 1460 1614 1666 1867 1972
The median of this set is 1614, which is the middle value. As you can see, the change from 1772 to 1972 did not affect the median.
Therefore, the answer is the median would not change.

what is x and y if answer is not whole number simplify the radical
The values of x and y in the triangle are 2√30 and 2√21
How to deterine the values of x and yThe value of y
From the question, we have the following parameters that can be used in our computation:
y : 6 = 14 : y
Express as fraction
y/6 = y/14
So, we have
y^2 = 14 * 6
Evaluate
y = 2√21
For the value of x
Here, we have
x^2 = y^2 + 6^2
So, we have
x^2 = (14 * 6) + 6^2
Evaluate
x^2 = 120
So, we have
x = 2√30
Hence, the values are 2√21 and 2√30
