a group of 25 students spent 1,625 minutes studying for an upcoming test. what prediction can you make about the time it will take 130 students to study for the test?
Thus, it will take 130 students approximately 8,450 minutes to study for the test.
Based on the information provided, we can predict the time it will take for 130 students to study for the test. A group of 25 students spent 1,625 minutes studying. To find the average time per student, we divide the total time by the number of students:
Using unitary method:
1,625 minutes ÷ 25 students = 65 minutes per student
Now, we can use this average time to predict the time for 130 students:
65 minutes per student × 130 students = 8,450 minutes
Therefore, it will take 130 students approximately 8,450 minutes to study for the test.

How to find the regression equation?First, pick two points from the table :
( 2, 7 ) and ( 4, 11 )
Use these points to find the slope :
Slope = ( y2 - y1 ) / ( x2 - x1 )
= ( 11 - 7 ) / (4 - 2)
= 2
Then use this to find the y - intercept and equation to be:
y - y1 = m ( x - x1 )

Answer:
equation: 17 +3m = 28.7m = 3.9Step-by-step explanation:
You want an equation and its solution to help you find the number of miles Carter must ride his bicycle each day (m) to total 28.7 miles after 3 more days, given he has already ridden 17 miles this week.
RelationThe total number of miles for the week will be 28.7. That will consist of the sum of miles already ridden (17) and the number each day multiplied by the remaining number of days.
The miles ridden each day is defined in the problem statement as "m". The number of remaining days is 3, so the total number of miles ridden on those days will be 3m.
Carter wants the sum to be ...
17 +3m = 28.7
This is the equation being asked for.
SolutionThis 2-step equation is solved in the usual way:
3m = 11.7 . . . . . . . . subtract 17 from both sides
m = 3.9 . . . . . . . . . divide both sides by 3
Carter would have to ride an average of 3.9 miles each day to reach his goal.

Additional comment
Your life experience should tell you how things add up. A total is the sum of its parts. Total miles = (miles already done) + (miles to go), for example.
Multiple things that are the same value can be "added" using multiplication: m + m + m = 3m, for example.

What is a rectangle?
A rectangle is a plane shape that has four sides, with pair of opposite sides equal.
To calculate the area of the shaded portion when a right triangle is removed from a rectangle,we use the formula below
Formula:
A' = (Length of the rectangle×Width of the rectangle)-(1/2×base of the triangle×height of the triangle)................... Equation 1
Where:
A' = Area of the shaded regionLength of the rectangle = 9 ydWidth of the rectangle = 6 ydBase of the triangle = 4 ydHeight of the rectangle = 2 ydSubstitute these values into equation 1

If a store is having a sale where all items are 25% off, write an expression for p, the price of the item, after the sale
An expressions for p, the price of the item are:
0.75p, p - 0.25p, (1 - 0.25)p
The correct options are A, E and H
Here, a store is having a 25% off sale.
And the item has a price of p.
The price of item would be p minus 25 percent of p, because 25% off means we have to pay 25% less than the original price.
We can represent this information in an expression form as:
p - (25% of p) ...........(1)
Using percentage formula, the 25% of p would be,
25% of p
= (25/100) × p
= (1/4) × p
= (0.25)p
So, expression (1) becomes,
p - (25% of p)
= p - 0.25p

true or false let a be a real square matrix. if a is diagonalizable then a is symmetric
False. let a be a real square matrix. if a is diagonalizable then a is symmetric
Explanation: Diagonalizability and symmetry are two different properties of a square matrix. A real square matrix A is diagonalizable if it can be transformed into a diagonal matrix D through a similarity transformation with an invertible matrix P, i.e., A = PDP^(-1). A matrix is symmetric if A = A^T, where A^T is the transpose of A.
While it is true that every symmetric matrix is diagonalizable, the converse is not necessarily true. In other words, not every diagonalizable matrix has to be symmetric.
Conclusion: The statement "if A is diagonalizable then A is symmetric" is false because diagonalizability does not guarantee symmetry.

a news agency publishes results of a recent poll. it reports that a certain candidate has a 10-point stronger support in town a than in town b because 45% of the poll participants in town a and 35% of the poll participants in town b supported the candidate. what margin of error should the news agency report for each of the listed estimates, 45%, 35%, and 10%? notice that 900 randomly selected registered voters participated in the poll in each town, and the reported margins of error correspond to 95% confidence intervals.
The news agency should report margins of error of 3.81%, 3.62%, and 7.43% for the estimates of support in town A, town B, and the difference in support between the two towns, respectively.
To calculate the margin of error for each estimate, we can use the formula:
Margin of Error = [tex]z* (\sqrt{(p*(1-p)}/n))[/tex]
where z* is the critical value of the standard normal distribution corresponding to the 95% confidence level (1.96), p is the proportion from the sample, and n is the sample size.
For the estimate of 45% support in town A:
Margin of Error = [tex]1.96 \times (\sqrt{(0.45*(1-0.45)}/900))[/tex] = 0.0381 or 3.81%
For the estimate of 35% support in town B:
Margin of Error = [tex]1.96 \times(\sqrt{(0.35*(1-0.35)}/900))[/tex]= 0.0362 or 3.62%
For the estimate of 10-point stronger support in town A than in town B:
We can calculate the margin of error as the sum of the margins of error for the estimates of support in town A and town B:
Margin of Error = 0.0381 + 0.0362 = 0.0743 or 7.43%

The modeling process begins with the framing of a conceptual model that shows the relationships between the various parts of the problem being modeled. This model helps to identify the mathematical correlations between variables and provides a foundation for developing a more detailed and accurate mathematical model.
The modeling process begins with the framing of a mathematical model that shows the relationships between the various parts of the problem being modeled. This model is often based on data analysis and utilizes statistical techniques to establish correlations between the different variables in the problem. Ultimately, the goal of the modeling process is to create a predictive tool that can be used to make informed decisions about the problem at hand.
Process models involve graphically representing processes or functions that capture, manage, store, and distribute information between the system and its environment and physical objects. One type of process model is the flowchart (DFD). A data flow is a diagram that shows the movement of data between external sources and processes and the data stored in the system. While several different tools have been developed for modeling, we focus only on data streams as they are effective tools for modeling. While not all organizations use all analytical methods, including these methods such as data flow, they have a significant impact on the development process.

B.
The graph is decreasing when x > 0.
C.
The graph is increasing when x > 0.
D.
The graph is decreasing when x < 0.
The correct answer is D. The graph is a downward parabola, which means it opens downwards and is decreasing. This occurs for all negative values of x, and is also decreasing for values of x close to zero.
What is Graph?A graph is a visual representation of data or information, typically shown using lines, bars, dots, or other symbols to illustrate relationships, trends, and patterns.
What is parabola?A parabola is a U-shaped curve that is symmetric and can be represented by a quadratic equation. It is a type of conic section and appears in many areas of mathematics and physics.
According to the given information:
The correct answer is D. The graph is a downward parabola, which means that it opens downwards and has a maximum point at the vertex. The vertex is located at x = 0, and since the graph is decreasing on both sides of the vertex, it means that it is decreasing when x < 0. As x approaches negative infinity, the graph becomes more and more steep, and as x approaches positive infinity, the graph becomes flatter and flatter. This behavior is typical of a quadratic function with a negative leading coefficient. In this case, the graph represents a situation where the dependent variable decreases as the independent variable increases up to a certain point, after which it starts increasing again.

Point Z is equidistant from the sides of ARST. C R Z A B S Which must be true? A. SZ&TZ
B. RZ =R BZ
C. CTZ = ASZ
D. ASZ=ZSB
Answer:
B. RZ =R BZ
Step-by-step explanation:
Since point Z is equidistant from the sides of ARST, it lies on the perpendicular bisectors of both sides. Therefore, CZ and SZ are perpendicular bisectors of AB and ST, respectively.
Option B is true because point R lies on the perpendicular bisector of AB, and therefore RZ = RB.
Answer: vv
Step-by-step explanation:
Since point Z is equidistant from the sides of ARST, it lies on the perpendicular bisector of the sides ST and AR.
Therefore, we can draw perpendiculars from point Z to the sides ST and AR, which intersect them at points T' and R', respectively.
Now, let's examine the options:
A. SZ & TZ: This is not necessarily true, as we do not know the exact location of point Z. It could lie anywhere on the perpendicular bisector of ST, and the distance from Z to S and T could be different.
B. RZ = RB: This is true, as point Z lies on the perpendicular bisector of AR, and is therefore equidistant from R and B.
C. CTZ = ASZ: This is not necessarily true, as we do not know the exact location of point Z. It could lie anywhere on the perpendicular bisector of AR, and the distances from Z to C and A could be different.
D. ASZ = ZSB: This is not necessarily true, as we do not know the exact location of point Z. It could lie anywhere on the perpendicular bisector of ST, and the distances from Z to A and B could be different.

8 mm
8 mm
Step-by-step explanation:
To calculate the surface area of a triangular pyramid, we need to find the area of each triangular face and add them together.
Using the formula for the area of a triangle (base x height / 2), we can find the area of one of the triangular faces:
base = 8 mm
height = 6.9 mm
area = (8 mm x 6.9 mm) / 2 = 27.6 mm²
Since there are four triangular faces, the total surface area of the pyramid is:
4 x 27.6 mm² = 110.4 mm²
Therefore, the surface area of this triangular pyramid is 110.4 mm².

Using the definition of logarithm, we have:
[tex]6^{3x} = 216[/tex]
[tex]6^{3x} = 6^3[/tex]
3x = 3
x = 1
2. x - 4 = log3 243
Using the definition of logarithm, we have:
[tex]3^{x - 4} = 243[/tex]
[tex]3^{x - 4} = 3^5[/tex]
x - 4 = 5
x = 9
3. log4 (4x - 20) = 5
Using the definition of logarithm, we have:
4⁵ = 4x - 20
1024 = 4x - 20
4x = 1044
x = 261
4. log9 (3 - x) = log9(5x – 15)
Using the property of logarithms that states that if log a b = log a c, then b = c, we have:
3 - x = 5x - 15
20 = 6x
x = 10/3
5. log81 (x + 20) = log81 (6x)
Using the property of logarithms that states that if log a b = log a c, then b = c, we have:
x + 20 = 6x
20 = 5x
x = 4
6. log9 (3x²) = log9 (2x + 1)
Using the property of logarithms that states that if log a b = log a c, then b = c, we have:
3x² = 2x + 1
3x² - 2x - 1 = 0
7. Using the quadratic formula, we have:
x = (-(-2) ± √((-2)² - 4(3)(-1))) / (2(3))
x = (2 ± √(16)) / 6
x = (2 ± 4) / 6
x = 1 or x = -1/3
8. log4(x - 1) = log4(12)
Using the property of logarithms that states that if log a b = log a c, then b = c, we have:
x - 1 = 12
x = 13
9. log7(5 - x) = log7 (5)
Using the property of logarithms that states that if log a b = log a c, then b = c, we have:
5 - x = 5
x = 0
10. logx (5x) = 2
Using the definition of logarithm, we have:
x² = 5x
x² - 5x = 0
x(x - 5) = 0
x = 0 or x = 5
Note that x = 0 is not a valid solution, since log 0 is undefined. Therefore, the only solution is x = 5.
