The Place valueof Thedigit 5 in 26,59,360 in Ten Thousand
Answer: True.
Step-by-step explanation:
Here we have the number:
26,59,360
To find the place value of the 5, we first need to count the number of decimals at the right of the 5 (until we reach the decimal point)
For this case, at the left of the 5 we have 4 decimals (9, 3, 6 and 0)
Then the place value of the 5 in that number will be 10^4
this is equal to:
10^4 = (10)*(10)*(10)*(10) = 10,000
This means that the place value of the 5 is then thousand.
Then the statement is true.

Find what minimum population size you need to have if you have a 99% confidence, 100 standard deviation and want a size 3 margin of error
A minimum population size of approximately 7373 to achieve a 99% confidence interval with a margin of error of 3 and a known standard deviation of 100.
How to calculate the minimum population size?To calculate the minimum population size required to achieve a 99% confidence interval with a margin of error of 3 and a known standard deviation of 100, we can use the following formula:
n = [(z-value × SD) / ME]²
Where:
n = the minimum sample size required
z-value = the critical value for the desired confidence level (99% in this case)
SD = the known standard deviation (100 in this case)
ME = the desired margin of error (3 in this case)
First, we need to determine the z-value for a 99% confidence level. Using a standard normal distribution table, we find that the z-value for a 99% confidence level is approximately 2.576.
Substituting the values into the formula, we get:
n = [(2.576 × 100) / 3]²
Simplifying this expression, we get:
n = 7373.08
Therefore, we would need a minimum population size of approximately 7373.

You are given the great circle of a sphere is a length of 25 miles. What is the volume of the sphere
The volume of the sphere is approximately 3431.82 cubic miles.
To find the volume of a sphere, we need the radius of the sphere. The length of a great circle is the circumference of the sphere, which is related to the radius by the formula C = 2πr, where C is the circumference and r is the radius.
In this case, we are given that the length of the great circle is 60 miles. We can use this information to find the radius of the sphere.
C = 2πr
60 = 2πr
Divide both sides of the equation by 2π:
r = 60 / (2π)
r = 30 / π
Now that we have the radius, we can use the formula for the volume of a sphere:
V = (4/3)πr³
V = (4/3)π(30/π)³
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)(27000/π²)
V = (4/3)(27000/9.87) (approximating π to 3.14)
V ≈ 3431.82 cubic miles
Therefore, the volume of the sphere is approximately 3431.82 cubic miles.

The point P=(1/2,y)lies on the unit circle shown below. What is the value of y in simplest form?
The value of y in simplest form for the point P = (1/2, y) lying on the unit circle is y = ± √(3)/2.
To find the value of y in simplest form for the point P = (1/2, y) lying on the unit circle, we can use the equation of the unit circle, which states that for any point (x, y) on the unit circle, the following equation holds: x^2 + y^2 = 1.
Plugging in the coordinates of the point P = (1/2, y), we get:
(1/2)^2 + y^2 = 1
1/4 + y^2 = 1
y^2 = 1 - 1/4
y^2 = 3/4.
To simplify y^2 = 3/4, we take the square root of both sides:y = ± √(3/4).
Now, we need to simplify √(3/4). Since 3 and 4 share a common factor of 1, we can simplify further: y = ± √(3/4) = ± √(3)/√(4) = ± √(3)/2.

A dinner was held to raise money for a children's museum. A ticket for one person cost $200 and a ticket for a couple (two people) cost $350. A total of 130 people attended the dinner, and the ticket sales total was $24,000. What is the total number of tickets that were sold?
Using simultaneous equations, during the dinner to raise money for a children's museum, 90 tickets were sold.
What are simultaneous equations?Simultaneous equations are two or more equations solved concurrently or at the same time.
Simultaneous equations are also called a system of equations.
The cost of one-person ticket = $200
The cost of two-people ticket = $350
The total number of attendees at the dinner = 130
The total ticket sales = $24,000
Let number of one-person ticket = x
Let number of two-people ticket = 2y
Equations:x + 2y = 130... Equation 1
200x + 250y = 24000... Equation 2
Multiply Equation 1 by 200:
200x + 400y = 26000... Equation 3
Subtract Equation 2 from Equation 3:
200x + 400y = 26000
-
200x + 350y = 24000
50y = 2000
y = 40
x = 130 - 2y
= 130 - 80

What is the median
Answer:
72 or 75
Step-by-step explanation:
If we are going in order then the median would be 72.
If we are going by what you posted, then it would be 75.
You were asking about the mean, so I though I would just add it in here.
So basically, the mean is just where you add up all the numbers, and then divide them by how many numbers you have.
For your problem, this is 39+87+72+88+75+87+15+53+53. This equals 569.
Now, lets count how many numbers we added: 1...2...3...4...5...6...7...8...9.
Ok, so lets divide the 569 by 9. This should get you 63.222...
That is your mean.

The fast algorithm to find a minimum cut in the flow network g d .v; e/ using a push-relabel algorithm is to first compute the residual network Gf of G. Then, apply a breadth-first search starting from any source vertex s in Gf. Then, the cut is defined by the set of vertices reachable from s. The capacity of the cut is the sum of the capacities of the edges crossing the cut.
To find a minimum cut in the flow network g d .v; e/ using a push-relabel algorithm, we first compute the residual network Gf of G. This is done by creating a new graph from G with each edge having a residual capacity equal to the difference between its capacity and the flow it has already been assigned. We then use a breadth-first search to traverse Gf, starting from any source vertex s in Gf. This will allow us to identify the set of vertices reachable from s in Gf. This set of vertices defines the minimum cut of G. The capacity of the cut is then computed by summing up the capacities of the edges crossing the cut.

A data set has 10 values.
The mean of the data in the set is 12.
The mean absolute deviation of the data in the set is 4.
What must be true?
Each value in the data set varies from 12 by exactly 4.
Each value in the data set varies from 12 by an average of 4.
No values in the data sete are less than 8 or greater than 16.
Half of the values in the data set are 8 and half of the values in the data set are 16.
How do you find the answer?
The value in the data set varies from 12 by an Average of 4.
The mean of the data set is 12 and the mean absolute deviation is 4.
Option 1: Each value in the data set varies from 12 by exactly 4.
This statement cannot be concluded based on the given information. The mean absolute deviation measures the average distance between each data point and the mean. It does not imply that each value varies by exactly 4 from the mean.
Option 2: Each value in the data set varies from 12 by an average of 4.
This statement is true. The mean absolute deviation of 4 indicates that, on average, each data point deviates from the mean by 4 units. It does not necessarily mean that each value varies by exactly 4, but the average deviation is indeed 4.
Option 3: No values in the data set are less than 8 or greater than 16.
This statement cannot be determined based on the given information. The mean and mean absolute deviation do not provide information about the specific values in the data set. It is possible for some values to be less than 8 or greater than 16 while still maintaining a mean of 12 and a mean absolute deviation of 4.
Option 4: Half of the values in the data set are 8, and half of the values in the data set are 16.

A contractor gets a 2% discount o n a monthly sand and gravel bill of $1,655.75 if the bill is paid within 10 days of the statement date. How much is saved by paying the bill within the 10-day period?
The contractor saved a total of $33.115 on his monthly bill of sand and gravel.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
The percentage is just like the amount of that value but in between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
Given that,
Amount of bill = $1,655.75
Discount percentage = 2%
So,
2% of $1,655.75
⇒ 2× 1,655.75/100
⇒ 0.02 × 1,655.75
⇒ 33.115
Hence "The contractor saved a total of $33.115 on his monthly bill of sand and gravel".

3. The factored polynomial is p(x) = (x - 1)(x - 5)
4. The factored polynomial is p(x) = (x + 3)²
What is a polynomial?A polynomial is a mathematical expression in which the power of the unknown is greater than or equal to 2.
3. To factorize the polynomial using the graph, we see that the polynomial cuts the x - axis at x = 1 and x = 5.
This implies that its factors are (x - 1) and (x - 5)
So, the factored polynomial is p(x) = (x - 1)(x - 5)
4. To factorize the polynomial using the graph, we see that the polynomial touches the x - axis at only one point x = -3. So,it has repeated roots
This implies that its factors are (x - (-3)) = (x + 3) twice
So, the factored polynomial is p(x) = (x + 3)²
