When constructing an angle bisector using a compass, all three arcs do not need to have the same radius.
To construct an angle bisector, you first place the point of the compass on one of the angle's vertices and draw an arc that intersects both sides of the angle. Next, you place the point of the compass on the other vertex of the angle and draw another arc that also intersects both sides of the angle. Finally, you draw a straight line through the point where the two arcs intersect, which will bisect the angle.
The radius of the compass does not affect the construction of the angle bisector, as long as the compass is set to a radius that is large enough to intersect both sides of the angle at some point. As long as the arcs intersect, the angle bisector can be accurately constructed, regardless of the radius of the arcs.
The complete question is:-
When constructing an angle bisector, the compass must be used to make three arcs. Do all three arcs need to have the same radius? Explain.
- Yes, because then the marks are equidistant from each other.
- Yes, because you need the points of intersection of the angle and arcs to form a parallelogram.
- No; the second two arcs must have the same radius but it can be different from the first.
- No; any three radii will work.

The equivalent for the expression 1/4a + (-6) - 3/4a + 2.8 is -(2+12.8a)
How do we find the equivalent of an expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

What is the median of 50?
The median of the first 50 whole numbers is 24.5.
The midway value in a given set of figures or data is referred to as the median. To get the average value for a given group of integers, three distinct metrics are employed in mathematics.
Non-negative numbers, which can be expressed without fractions, are known as whole numbers.
The first fifty whole numbers are 0,1,2,3,4,5................49
The number of terms in the data, n=50.
Let [tex]n^{th}[/tex] term be denoted by [tex]t_{n}[/tex]
As the number of terms is even, thus the median will be [tex]\frac{t_{\frac{n}{2} } +t_{\frac{n}{2} }+1}{2}[/tex]
Substitute n with 50.
Median = [tex]\frac{t_{\frac{50}{2} } +t_{\frac{50}{2} }+1}{2}= t_{25}+t_{26} /2[/tex]
The 25th term of the sequence is 24.
The 26th term of the sequence is 25.
Thus, median = 24+25/2 = 49/2 = 24.5

A sequence can be described formally as a function from natural numbers (the positions of the sequence's elements) to the items at each of those positions.
A sequence is a list of elements that has been arranged in a certain way. For instance, the sequence 3, 7, 11, 15,... is a sequence because it follows a pattern where each term is created by adding 4 to the term before it.

In substitution method we have to put the the value of one variable from one equation to the other equation. Then we solve the equation and can find the value of variable x and y.
In the given question we have to explain how we can solve for x and y using substitution.
In the Substitution method we find the value of one variable in term of other variable from the one equation then we put the value of that variable in other equation. After putting the value of that variable in other equation, equation converts into the similar variable. Then after solving we can easily find the value of one variable. After finding the value of one variable we put the value of that variable in first equation. By this we can find the value of both variable.

Explain the term standard deviation?Empirical principle
If your frequency distribution follows a normal distribution, the standard deviation and mean combined might help you determine where the majority of the values are located.
The 68-95-99.7 rule, often known as the empirical rule, reveals your values to you:
Nearly 68% of scores are within one deviation of the mean, nearly 95% are within two standard deviations, and nearly 99.7% are within three standard deviations.Thus, the standard deviation is a less trustworthy indicator of variability for non-normal distributions and should be combined with other metrics like range or interquartile range.

If$2500was invested 6 years ago, andtheinterestwascompoundedquar-terly,whatwastheinterestrateifthecurrentvalueis$3425?
Answer:
The interest rate was 5.24%.
Step-by-step explanation:
You can use the following formula to calculate the interest rate:
i=n*((A/P)^1/nt-1), where:
i= interest rate
n= number of times interest is compounded= 4
A=value of investment= 3425
P= principal= 2500
t=time= 6
Now, you can replace the values on the formula:
i=4*((3425/2500)^1/4*6-1)
i=4*(1.37^1/24-1)
i=4*0.0131
i=0.0524
According to this, the answer is that the interest rate was 5.24%.
a number has three distinct digits, the sum of the digits equals the products of the digits. how many three digit numbers satisfy this condition?
Only one three digits number 111 would satisfy this condition.
Let the three digits be x, y and z. Since the sum of the digits is equal to the product of the digits, we can write x + y + z = xyz
Simplifying the equation, we get x + y + z - xyz = 0
This is a quadratic equation in the form ax2 + bx + c = 0 where a = 1, b = 1 and c = -xyz
To solve this equation, we use the quadratic formula: x = [-b ± √(b2 - 4ac)]/2a
In this case, x = [-1 ± √(1 - (-4 * 1 * (-xyz))]/2
Since xyz must be a positive integer, the only solution is when the square root of 1 - (-4 * -xyz) is 0
This means xyz must be 1, so x + y + z = 1 + y + z = 3
Since x, y and z are all distinct digits, the only possible solution is when x = 1, y = 1 and z = 1, giving the solution 111.

Why is it called linear function?
A linear function is a type of function that can be expressed in the form of a linear equation with one or more variables.
The equation is written as y = mx + b, where m is the slope and b is the y-intercept. The slope is the rate at which the line rises or falls and the y-intercept is the point where the line crosses the y-axis. The slope and y-intercept of a linear function are constants, meaning that the line does not curve or change direction. This is why it is called a linear function.
When calculating linear functions, the equation is used to identify the slope and the y-intercept. The slope and y-intercept are then used to plot the points on a graph. A linear equation has the form y = mx + b, where m is the slope and b is the y-intercept. The slope indicates the rate of change of the function and the y-intercept indicates the point where the line crosses the y-axis. To find the slope of a linear function, the equation is solved for m, which is the rise over run. To find the y-intercept, the equation is solved for b, which is the y-value when x = 0. Once the slope and y-intercept are determined, the points can be plotted on a graph and the linear equation can be written.
In summary, a linear function is a type of function that can be expressed in the form of a linear equation. The equation of the linear function is used to identify the slope and y-intercept, which are then used to plot the points on a graph. Linear functions can be used to model many real-world situations and to solve for x and y values for any given point.

A recipe that yields 30 servings calls for 3/4 cup flour. You want to prepare only 10 servings. After scaling the recipe to yield 10 servings, how much flour will you need?.
The number of servings that can be made from 3 / 4 cups, the number of cups of flour needed for 10 servings is 1/4 cups.
Given :
First the number of servings that can be made per cup :
= Number of servings / Number of cups
= 30 / 3/4
= 30 * 4 / 3
= 120 / 3
= 40 servings
To get 10 servings therefore, you would need:
= Number of servings needed / Number of servings per cup
= 10 / 40
= 1/4 cups
Hence the flour will be needed is 1/4 cup is needed.

A number is said to be prime if the integers smaller than its square root cannot divide it, as numbers higher than its square root cannot possibly do so.
what is square root ?A mathematical concept known as a square root is a factor of a number that, when multiplied by itself, equals the original value. For instance, 3 and -3 are the square roots of 9. Starting in the second millennium BC, the Babylonians created effective methods for approximating square roots.

In other words, if we encounter a number when counting from 2 to sqrt(N), and that number is a factor of N .
then indicates that the number has more than two factors and is thus not a prime number.
Otherwise, if we are unable to locate any factors for N, it is likely that N only has two factors, one and itself, making it a prime number.
