Missing value in frequency distribution table
Answers
Based on the data, the total number of people would be 350. So the missing value in the table would be 54.
How to find missing value from table?To find the missing value of people in the graph we must do the following procedure. We must add the number of people who are already registered in the graph in the frequency column.
Additionally, we must establish a total number of people, for example 350. In this case we must subtract the result of the people registered in the graph from the total number of people:
350 - 295 = 54.
Then we can establish that the remaining number of people (54) corresponds to the frequency table.

systems of equations by substitution
Answers
Answer: We can solve the system of equations using the substitution method.
First, we'll isolate "y" in one of the equations and substitute it into the other equation:
Y = x - 11
7x + 7y = -21
Substituting the first equation into the second equation:
7x + 7(x - 11) = -21
7x + 7x - 77 = -21
14x = 56
x = 4
Now that we have found the value of x, we can substitute it back into one of the original equations to find the value of y:
Y = x - 11
Y = 4 - 11
Y = -7
The solution to the system of equations is (x, y) = (4, -7).
Step-by-step explanation:
The value of x and y in the equation is 4 and -7 respectively
What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 14 4x − 4y = 4.
Using substitution method to solve the system,
y = x-11 equation 1
7x+7y = -21 equation 2
substitute x-11 for y in equation 2
7x + 7( x-11) = -21
7x + 7x -77 = -21
14x = -21+77
14x = 56
divide both sides by 14
x = 56/14
x = 4
substitute 4 for x in equation 1
y = 4-11
y = -7
therefore the value of x and y is 4 and -7 respectively

Homes without a pool will sell faster in that area than homes with a pool
Answers
The correct answer is option b.The approximate value of pool in that area is $20.000c.
What is approximate value?A value that is similar to another value but not exactly equal to it is referred to as an approximation number. When the outcomes of the numerical calculations are unknown, the approximation is applied. They are typically used when greater place value decimal numbers emerge as a result.
Approximate value of a pool in the area = Value of home with a swimming pool in the area - Value of home without a swimming pool in the same area.
Value of home with a swimming pool in the area = $250,000
Value of home without a swimming pool in the same area = $230,000.
The approximate value of pool in the area = 250000 - 230000 = 20000.

What does average mean?
The average is calculated by dividing the total number of values by the total number of values. It can also be described as mean. The mean in statistics is the average value across the specified sample or data set.
Mean, median, and mode are the three primary categories of average. Each of these methods operates a little bit differently and frequently yields values that diverge a little bit from the norm. The most popular type of average is the mean.

A city planner designs a park that is a quadrilateral with vertices at J(−3, 1), K(3, 3), L(5, −1), and M(−1, −3). There is an entrance to the park at the midpoint of each side of the park. A straight path connects each entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane represents 10 meters, what is the total length of the paths to the nearest meter? Round your answer to the nearest whole number.
Answers
Answer: To determine the length of the paths connecting the entrance to the opposite entrance, we first need to find the midpoint of each side of the park. Then, we will use the distance formula to calculate the distance between each pair of midpoints.
Let's begin by finding the midpoint of each side of the park.
JK: (-3 + 3, 1 + 3) / 2 = (0, 2)
KL: (3 + 5, 3 - 1) / 2 = (4, 2)
LM: (5 - 1, -1 - -3) / 2 = (2, -2)
MJ: (-1 + -3, -3 + 1) / 2 = (-2, -1)
Next, we'll use the distance formula to calculate the distance between each pair of midpoints.
JK: sqrt((4 - 0)^2 + (2 - 2)^2) = sqrt(16 + 0) = 4
KL: sqrt((2 - 4)^2 + (-2 - 2)^2) = sqrt(16 + 16) = 4 sqrt(2)
LM: sqrt((-2 - 2)^2 + (-1 + 2)^2) = sqrt(16 + 9) = sqrt(25) = 5
MJ: sqrt((-2 - 0)^2 + (-1 - 2)^2) = sqrt(4 + 9) = sqrt(13)
The total length of the paths is 4 + 4 sqrt(2) + 5 + sqrt(13), which when rounded to the nearest whole number is 14.

Step-by-step explanation:
We can use the law of sines to solve for x
The law of sines says the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides (and angles)
In this triangle
the side with length 12√3 is opposite 60°
the side with length x is opposite 90°
Using the law of sines,
[tex]\dfrac{12\sqrt{3}}{\sin60}=\dfrac{x}{\sin 90}\\[/tex]
sin 60 = [tex]\dfrac{\sqrt{3}}{2}[/tex]
sin 90 = 1
[tex]\rightarrow \dfrac{12\sqrt{3}}{\dfrac{\sqrt{3}}{2}}=\dfrac{x}{1}\\\\\\x = 12\sqrt{3} \div \dfrac{\sqrt{3}}{2}}\\\\\textrm{When dividing fractions, flip the divisor and multiply}\\\\\rightarrow 12\sqrt{3} \times \dfrac{2}{\sqrt{3}}\\\\\textrm{$\sqrt{3}$ cancels out from numerator and denominator}:\\\\\\\rightarrow x = 12 \times 2 = \boxed{24}\\\\\\[/tex]
To solve for y we can again use the law of sines
[tex]\dfrac{y}{\sin 30} = \dfrac{x}{\sin 90}\\\\\textrm{again, as before $\sin 90$ is 1}\\\\\rightarrow \dfrac{y}{\sin 30} = x\\\\\rightarrow x = \dfrac{y}{\sin 30}\\\\\rightarrow y = x \sin 30\\\\\sin30 = \dfrac{1}{2}[/tex]
So y = x/2 = 24/ 2 = 12
ans:
x = 24, y = 12
Note
Another way to solve this question is to first recognize the triangle as a 30-60-90 right triangle
In a triangle of this kind, if the longest side side is a, the shortest side is a/2, and the third side is √3/2a
We could have solved this in this manner also
Here longest side = x, shortest side is y
The other side is 12√3 = x √3/2
So x = 12√3 ÷ √3/2 = 24 (as in the first method)
y = x/2 = 12
This approach is ok too, I find it less intuitive and we have to remember the ratios

A. The Adjusted Trial Balance
B. The Trial Balance
D. The Adjustments
C. The Income Statement
Answers
Answer: C
Step-by-step explanation:
The column on an accounting worksheet that may not balance at the end of an accounting period is the Adjustments column.
The Adjustments column on an accounting worksheet includes all the adjusting entries that are needed to update the accounts before the financial statements are prepared. These adjustments can include accruals, deferrals, depreciation, and other adjustments that need to be made to the accounts to accurately reflect the financial position of the company.
Since the Adjustments column is used to record these adjusting entries, it is possible that this column may not balance at the end of the accounting period, as the adjustments may not perfectly offset each other. However, this is not a problem, as the purpose of the worksheet is to help prepare the financial statements, not to balance each individual column.
Therefore, the correct answer is option D, the Adjustments column.
Answer:
C. The Income Statement
Step-by-step explanation:
The Income Statement column on an accounting worksheet may not balance at the end of an accounting period.
An accounting worksheet is a tool used by accountants to help organize and summarize financial information and to prepare financial statements. The worksheet is typically a multi-column form that includes columns for the unadjusted trial balance, adjustments, adjusted trial balance, income statement, and balance sheet.
The Adjustments column is used to record adjusting entries and to update the account balances to reflect accruals, deferrals, and other accounting adjustments. The Adjusted Trial Balance column is the result of the adjustments made in the Adjustments column and should include all the account balances that will be used to prepare the financial statements.

The median number of canned goods collected = 18.
The range of data for Mr. Garcia's homeroom = 11.
The IQR (interquartile range) of data = 4.25.
Ms. Vicario's homerooms:
The range of data = greater than 11.
The IQR of data = greater than 4.25.
The number of canned goods collected = more variable than the number of canned goods collected by Mr. Garcia's homeroom.
Based on these observations.
We can conclude that,
Mr. Garcia's homeroom had a more consistent collection of canned goods. i.e
Smaller range and IQR.
Ms. Vicario's homeroom varied more widely with the collection of canned goods.
i.e
Wider range and IQR

find the ear in each of the following cases: input area: output area: stated rate (apr) compounding periods per year effective rate (ear) 7.80% 4 15.30% 12 12.40% 365 11.40% infinite
Answers
The effective annual rate (EAR) is the actual rate of interest that is earned or paid over a given period of time, taking into account the compounding of interest. For example, a stated rate of 7.80% with 4 compounding periods per year would result in an EAR of 15.30%.
The effective annual rate (EAR) is a measure of the actual rate of interest that is earned or paid over a given period of time. It takes into account the effect of compounding, which is the process of earning interest on both the principal and the accumulated interest. This means that the rate of return can increase over time. The EAR is calculated by taking the stated rate of interest, which is the rate of interest stated by the lender, and multiplying it by the number of compounding periods per year. For example, if the stated rate is 7.80% and the compounding periods per year are 4, then the EAR would be 15.30%. Similarly, if the stated rate is 12.40% and the compounding periods per year are 365, then the EAR would be 11.40%. If the compounding period is infinite, then the EAR will be the same as the stated rate, in this case 12.40%. Therefore, the EAR is the actual rate of return that is earned or paid over a given period of time.

The shortest distance between the two skew lines is equal to 11√38 / 38 units.
How to find the shortest distance between two skew lines in space
According to linear algebra, lines are defined by vectorial equations of the form:
(x, y, z) = P(x, y, z) + t · T(x, y, z)
Where:
P(x, y, z) - Point contained in the line.t - Parameter.T(x, y, z) - Vector slope.And the shortest distance between two skew lines is determined by the following expression:
[tex]d = \frac {|[P_{2} (x, y, z) - P_{1}(x, y, z)] \bullet [T_{1} (x, y, z) \times T_{2} (x, y, z)]|}{|T_{1} (x, y, z) \times T_{2} (x, y, z)|}[/tex]
First, determine the points contained in each line:
P₁(x, y, z) = (3, 2, 1)
P₂(x, y, z) = (2, 4, - 1)
Second, find each vector slope:
T₁(x, y, z) = (2, 1, 0) - (3, 2, 1)
T₁(x, y, z) = (- 1, - 1, - 1)
T₂(x, y, z) = (3, 0, - 2) - (2, 4, - 1)
T₂(x, y, z) = (1, - 4, - 1)
Third, determine the vector subtraction:
P₂(x, y, z) - P₁(x, y, z) = (2, 4, - 1) - (3, 2, 1)
P₂(x, y, z) - P₁(x, y, z) = (- 1, 2, - 2)
Fourth, determine the cross product:
T₁(x, y, z) × T₂(x, y, z) = (- 1, - 1, - 1) × (1, - 4, - 1)
T₁(x, y, z) × T₂(x, y, z) = (- 3, - 2, 5)
Fifth, use the dot product:
[tex][P_{2} (x, y, z) - P_{1}(x, y, z)] \bullet [T_{1} (x, y, z) \times T_{2} (x, y, z)] = (- 1, 2, - 2) \,\bullet\,(- 3, - 2, 5)[/tex]
[tex][P_{2} (x, y, z) - P_{1}(x, y, z)] \bullet [T_{1} (x, y, z) \times T_{2} (x, y, z)] = 3 - 4 - 10[/tex]
[tex][P_{2} (x, y, z) - P_{1}(x, y, z)] \bullet [T_{1} (x, y, z) \times T_{2} (x, y, z)] = - 11[/tex]
Sixth, calculate the norm of the cross product:
|T₁(x, y, z) × T₂(x, y, z)| = √[(- 3)² + (- 2)² + 5²]
|T₁(x, y, z) × T₂(x, y, z)| = √38
Finally, determine the shortest distance between the two skew lines:
d = |- 11| / √38
d = 11 / √38
d = 11√38 / 38

What is the solution to an equation?
In order to make the equation's equality true, the unknown variables must be given values as a solution. In other words, the definition of a solution is a value or set of values (one for each unknown) that, when used as a replacement for the unknowns, transforms the equation into equality.
xy' + y = 3xy², y(1) = -3
This is Bernoulli equation: y' + (1/x)y = 3y²;
Let u = y^(1 - 2) = 1/y is new function.
Then u' = - y'/y
or
y' = -u'/u²;
y = 1/u.
Substitute all this in our ODE: - u'/u² +(1/x)/u = 3/u², or u' - (1/x)u = -3.
we get linear, 1st order not homogenies ODE:
integrated factor:
μ = e∫(-1/x)dx = e-lnx = 1/x²

Consider a market characterized by the following inverse demand and supply functions: PX = 50 − 4QX and PX = 10 + 2QX. Compute the surplus producers receive when a $30 per unit price floor is imposed on the market.
A $75
B $35
C $25
D $50
Answers
Computing the surplus producers receive when a $30 per unit price floor is imposed on the market is option C.$25.
How did we get the value?To calculate the surplus producers receive, we need to find the difference between the price they receive at a given quantity and the price they would have received in the absence of the price floor.
When a price floor of $30 per unit is imposed on the market, the quantity supplied and demanded at this price are:
QX = (50 - 30)/4 = 5 units (demand)
QX = (30 - 10)/2 = 10 units (supply)
So, the surplus received by the producers is the difference between the price floor and the price they would have received in the absence of the price floor:
Surplus = 30 - (10 + 2 * 10) = 30 - 30 = $0.
However, the surplus for consumers is the difference between the price they would have paid in the absence of the price floor and the price floor:
Surplus = (50 - 4 * 5) - 30 = 25 - 30 = -$5.
So, the total surplus received by producers and consumers combined is $0 + (-$5) = -$5, which means that the price floor imposes a dead weight loss on the market.

Answers
Let V be an inner product space, S and S0 be subsets of V, and W be a finite-dimensional subspace of V. To prove the other side,
1 ) Suppose (e1,…,en) is basis for W. Suppose x∈(W⊥)⊥. Consider the projection w of x onto W, specifically:
w=⟨x,e1⟩e1+…+⟨x,en⟩en∈W.
Then, x−w is perpendicular to each ei, since
⟨x−w,ei⟩=⟨x,ei⟩−∑j=1n⟨⟨x,ej⟩ej,ei⟩=⟨x,ei⟩−∑j=1n⟨x,ej⟩⟨ej,ei⟩=⟨x,ei⟩−∑j=1n⟨x,ej⟩δij=⟨x,ei⟩−⟨x,ei⟩=0.
Since the linear map ⟨⋅,x−w⟩ is constantly 0 on the basis of W, it is constantly zero on all of W, hence x−w∈W⊥.
But then, since x∈(W⊥)⊥, we have ⟨x−w,x⟩=0, and since ⟨x−w,w⟩=0,
∥x−w∥2=⟨x,x−w⟩−⟨w,x−w⟩=0,
i.e. x=w∈W, completing the proof.
2 ) Suppose that w∈(W⊥)⊥
then ⟨w,x⟩=0
for all x∈W⊥
If w∉W, then w=v+v′ where v∈W and v′∈W⊥∖{0}.
Then.
0=⟨w,x⟩=⟨v,x⟩+⟨v′,x⟩=⟨v′,x⟩
for all x∈W⊥.
However, v′∈W⊥ and ⟨v′,v′⟩≠0 so it is a contradiction.
