If bean bags are tossed towards a circle. what is the probability a bean bag lands closer to the center of the circle than to the edge of the circle?
0.25 is the probability a bean bag lands closer to the center of the circle than to the edge of the circle.
What is the probability in simple terms?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.Let the radius of the circle be r.
Now the distsnce of the edge of the circle from the center is r units.
Now for any point lying in the circle, the sum of the distance of that point
from the center and from the nearest edge of the circle is r.
Thus, the bag will land closer to the circle if it lies within r/2 distance from the center.
Now, the area of the inner circle with radius r/2 is = [tex]\pi (\frac{r}{2})^{2} = \pi \frac{r^{2} }{4}[/tex]
The area of the actual circle = πr²
Thus, the bean bag will land closer to the center if it lies within the inner circle of area = π r²/4
Hence, the required probability = [tex]\pi r^{2} /4/ \pi r^{2}[/tex] = 1/4 = 0.25

SAT/ACT Mitsu travels a certain distance at 30 miles per hour and returns the same route at 65 miles per hour. What is his average speed in miles per hour for the round trip?
A 32.5
B 35.0
C 41.0
D 47.5
E 55.3
The average speed in miles per hour for the round trip is (D) 47.5.
What do we mean by average?In layman's terms, an average is a single number chosen to represent a set of numbers, typically the sum of the numbers divided by the number of numbers in the set (the arithmetic mean). The average of the numbers 2, 3, 4, 7, and 9 (summed to 25) is 5, for example. An average could be another statistic, such as the median or mode, depending on the context. For example, the average personal income is frequently given as the median—the number below which 50% of personal incomes fall and above which 50% of personal incomes fall—because the mean would be misleadingly high if a few billionaires' personal incomes were included.To find the average speed:
30 miles + 65 miles = 95Formula: Sum of terms/Number of terms
95/2 = 47.5Therefore, the average speed in miles per hour for the round trip is (D) 47.5.

Algebraic equations are represented by the equal symbol (=).
Data and Calculations:y + 5x = x² + 10 and y = 4x – 10
Substitute y = 4x - 10:
4x – 10 + 5x = x² + 10
4x - 10 = x² – 5x + 10
Add 10 to both sides:
4x - 10 + 10 = x² - 5x + 20
4x = x² - 5x + 20
Subtract 4x from both sides:

a measuring tool captures rain falling at a constant.The table shows the height of rainwater in the measuring tool and the number of minutes it rains.what is the constant of proportionality for the realationship of millimeters of rainwater to time in hours
The constant of proportionality for the relationship of millimeters of rainwater to time in hours is 48 millimeter/hour.
Given that the measuring tool captures rain falling at a constant.The table shows the height of rainwater in the measuring tool and the number of minutes it rains as shown in attached image.
A ratio is a mathematical comparison between two numbers. In proportion, if two given sets of numbers increase or decrease by the same ratio then the given ratios are said to be proportional.
Now we will calculate the proportion by using the formula
Ratio=(r₂-r₁)/(t₂-t₁)
Here, r₁=4, r₂=8, t₁=5, t₂=10
So, r₂-r₁=8-4=4 and
t₂-t₁=10-5=5
Now, we will convert the time from min to hour by dividing it with 60, we get
t₂-t₁=5/60
Substitute this value in above equation, we get
Ratio=4/(5/60)
Ratio=(4×60)/5
Ratio=4×12
Ratio=48 mm/hr
Hence, the constant of proportionality for the relationship of millimeters of rainwater to time in hours by using the given table is 48 mm/hr.

Give the domain and range of the quadratic function whose graph is described.
The vertex is (-5, -8) and the parabola opens up.
The domain of f is ?
The domain of f is [-5, ∞) because the vertex is the global minimum of a parabola that opens up.
The domain of any polynomial, including quadratics, is (–∞, ∞).
The domain of a parabola is always all real numbers (sometimes written (−∞,∞). The domain is all real numbers because every single number on the x− axis results in a valid output for the function (a quadratic).
When x=−b2a, y=c−b24a. Therefore the maximum or minimum value of the quadratic is c−b24a. Whether it is the maximum or minimum can be determined by examining the sign of a. If a is positive, then the range is y≥c−b24a
Hence, The range here is [-5, ∞), because the vertex is the global minimum of a parabola that opens up, and the global minimum is the lowest value.

The perimeter, P, of a rectangle is found using the formula P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle.
Solution:
The formula for the perimeter of a rectangle is, P = length + breadth + length + breadth.
As you stated the formula of a rectangle is P (perimeter) = 2W (the two widths added together) + 2L (the two lengths added together).
To solve this algebraically you need to define your variable, or unknown, which in this case is the width or "W".
Now set this same equation with any symbol you wish, "x" is often used, and solve for x. You could keep W instead of X also if it makes it easier to work on the problem.
P= 2x + 2L
isolate the 2x by subtracting 2L from both sides.
P-2L=2x
Now isolate the x by dividing both sides by 2 and you have
P-2L/2=x
x will be W. Just put in the numbers P and L and you will have solved for W.
One More Solution :
The perimeter of a rectangle is given by the following formula:
P = 2W + 2L
To solve this formula for W, the goal is to isolate this variable to one side of the equation such that the width of the rectangle (W) can be solved when given its perimeter (P) and length (L).
P = 2W + 2L
subtract 2L from both sides of the equation
P - 2L = 2W + 2L - 2L
P - 2L = 2W
divide both sides of the equation by 2
(P - 2L)/2 = (2W)/2
(P - 2L)/2 = (2/2)W
(P - 2L)/2 = (1)W
(P - 2L)/2 = W
Thus, given that the perimeter (P) of a rectangle is defined by P = 2W + 2L ,
then its width (W) is given by W = (P - 2L)/2

The equation y + 6 = 1/3 (x - 9) is written in point-slope form. What is the equation written in slope-intercept form?
A. y = 1/3 x -3
B. y = 1/3 x + 9
C. y = 1/3 x - 9
D. y = 1/3 x + 3
I appreciate all of your answers, even if they are wrong, if answers are taken up but you still would like to answer, please put in the comments. Have an awesome day!!! :)
C. y = 1/3 x - 9
Step-by-step explanation:The slope-intercept form is one way to represent a linear function that is set equal to y.
Simplifying and Solving
To find slope-intercept form from point-slope you should simplify the equation and then solve for y.
y + 6 = 1/3 (x - 9)Firstly, distribute the 1/3.
[tex]y+6=\frac{1}{3}x-3[/tex]Then, subtract the 6 from both sides.
[tex]y = \frac{1}{3} x - 9[/tex]This means that the slope-intercept form is y = 1/3 x - 9.
What Slope-Intercept Form Shows
We use slope-intercept form for 2 main reasons; it shows the slope and the y-intercept of a line (hence the name). The formula of slope-intercept is y = mx + b. In this formula, m is the slope and b is the y-intercept.
So, the slope of the line above is 1/3. The y-intercept of the line is -9.
Find a₁ for a geometric sequence with the given terms. a₉ = 1/2 and a₁₂ = 1/16
The first term of the given sequence is a(1) = 128
The formula for the nth term of a geometric sequence is:
a(n) = a(1) . rⁿ⁻¹
In the above formula, a(1) refers to the first term while r refers to the common ratio.
Information from the problem.
a(9) = 1/2 and a(12) = 1/16
Substitute n = 9 into the formula, we get:
a(9) = a(1) . r⁸
1/2 = a(1) . r⁸
Substitute n = 12 into the formula, we get:
a(12) = a(1) . r¹¹
1/16 = a(1) . r¹¹
Divide a(12) by a(9):
1/16 : 1/2 = ( a(1) . r¹¹ ) : (a(1) . r⁸ )
Since a(1) terms are cancelled out, we have:
2 : 16 = r¹¹ : r⁸
1/8 = r³
r = 1/2
Substitute r = 1/2 into a(9) :
a(9) = a(1) . r⁸
1/2 = a(1) . (1/2)⁸
a(1) = 1/2 : (1/2)⁸ = (1/2)¹⁻⁸
= (1/2)⁻⁷ = 2⁷

By elimination, the solution of the system of equations, 20x + 5y = 120 and 10x + 7.5y = 80, is (5 , 4).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in x and y, a variable should be eliminated by adding/subtracting the two equations.
Multiply first equation 2 by 2.
10x + 7.5y = 80 (equation 2)
20x + 15y = 160
Subtracting the two equations will eliminate the variable x.
20x + 15y = 160 (equation 2)
20x + 5y = 120 (equation 1)
0x + 10y = 40
y = 4
Substitute the value of y to any of the two equations and solve for x.
20x + 5y = 120 (equation 1)
20x + 5(4) = 120
20x = 120 - 20
20x = 100
x = 5

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation.
[tex]A^{2} + B^{2} + C^{2}[/tex]
The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. This theorem can be expressed as, c2 = a2 + b2; where 'c' is the hypotenuse and 'a' and 'b' are the two legs of the triangle.
So, We can write,
Consider the triangle given above:
Where “a” is the perpendicular,
“b” is the base,
“c” is the hypotenuse.
According to the definition, the Pythagoras Theorem formula is given as:
[tex]Hypotenuse^{2}[/tex] = [tex]Perpendicular^{2}[/tex] + [tex]Base^{2}[/tex]
[tex]C^{2} = A^{2} + B^{2}[/tex]
