The given statement is true that the points on a perpendicular bisector of a line segment are equidistant from the segment’s endpoints.
A line that splits another line segment into two equal halves by intersecting it perpendicularly is known as a perpendicular bisector. A rule, compass, and pencil can be used to create a perpendicular bisector.
When two lines cross at right angles or 90 degrees, they are said to be perpendicular to one another. A line that splits a line into two equally sized parts is known as a bisector. A line segment's perpendicular bisector suggests that it meets the segment at a 90-degree angle and splits it into two equal halves.
Perpendicular bisector theorem"Perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment’s endpoints".

you are making a cake and have already put in all of the ingredients except the eggs. you go to the refrigerator and find that there are no eggs, which results in the condition known as
The condition known as "eggless baking" is a common problem when baking cakes and other desserts.
It can be caused by not having eggs in the refrigerator or by forgetting to add them to the recipe. Without eggs, the cake batter lacks structure and will not hold together when baked. Without the proteins from the eggs, the cake will be denser and less moist.
Additionally, the cake may not rise as much as desired and the texture may be crumbly or gummy. To solve this problem, you can try substituting other ingredients such as mashed bananas, applesauce, or yogurt. However, it is best to add eggs if possible to ensure the best results.

(a) The quadratic equation (x+2)² +3k-1=0 has two real and distinct roots, where k is a constant. Find the range of values of k.
Answer: This means that the range of values of k is k ∈ [-1/3, 1/3].
Step-by-step explanation: The quadratic equation (x+2)² +3k-1=0 can be written as (x+2)² = 1-3k. For the equation to have two real and distinct roots, the expression under the square root must be nonnegative. Therefore, we have the inequality 1-3k ≥ 0. Solving this inequality gives us -1/3 ≤ k ≤ 1/3. This means that the range of values of k is k ∈ [-1/3, 1/3].
The 2 digit number which become 5 by 6th of itelf when it digit are revered. The difference in the digit of the
number being 1, then the two digit number i
After solving the two digit number is 45.
In the given question,
The 2 digit number which become 5 by 6th of itself when it digit are revered.
The difference in the digit of the number being 1, then we have to find the two digit number.
Let the two digit number = 10y+x
When we reversed the number then the number is 10x+y
As given that;
10y+x = 5/6(10x+y)
Multiply by 6 on both side, we get
60y+6x = 50x+5y
Subtract 5y on both side, we get
55y+6x = 50x
Subtract 50x on both side, we get
55y-44x = 0
Divide by 11 on both side, we get
5y-4x = 0
4x-5y = 0......................(1)
It is given that the difference between the number is 1.
x-y = 1..................(2)
Multiply by 4 in equation 2
4x-4y = 4.........................(3)
Now subtract equation 3 and 1, we get
y = 4
Now putting the value of y in equation 2
x-4 = 1
Add 4 on both side, we get
x = 5
Since the number is 10y+x. So
10y+x = 10(4)+5
10y+x = 45

in how many ways can a committee with 4 democrats and 2 republicans be formed from a group of 7 democrats and 5 republicans?
A committee with 4 democrats and 2 republicans formed from a group of 7 democrats and 5 republicans can be created in a total of 350 ways. Therefore, the option C holds true.
The calculation of the same has been shown as below,
A group has 7 Democrats and 5 Republicans.
Committee with 4 Democrats and 2 Republicans = 7C4 x 5C2
7C4 x 5C2 = 7! / (4! 3!) x 5! / (2! 3!)
7C4 x 5C2 =(7×6×5 / 3×2×1) x (5×4 / 2×1)

Use Infinite differences to write the linear function that represents the given data set.
The linear equation on the table is the one in option D.
y = 25*x + 45
How to write the linear function?
A general linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know two points on the line, (x₁, y₁) and (x₂, y₂), the slope can be written as:
a = (y₂ - y₁)/(x₂ - x₁)
Using the first two points, (0, 45) and (1, 70) we can get the slope:
a = (70 - 45)/(1 - 0) = 25
And because of the point (0, 45) we know that the y-intercept is b = 45, then the linear equation is:
y = 25*x + 45
So the correct option is D.

Given the equation of curve:
[tex]y = 3+ 4x^\frac{3}{2}[/tex]
The length of the curve is given by [tex]L= \int\limits^a_b {\sqrt{1+(y^[/tex]
Where y^ is derivative of y with respect to x
So [tex]y= 4*(3/2) * \sqrt{x}= > 6 \sqrt{x}[/tex]
Given a=1 and b=0

let 1+36x be t

How to find the worth of machine he can sell to earn a particular amount?Larry thinks the big money is in rowing machines. If Larry switches jobs,
he will earn a 12% commission on all the machines he sells. For Larry to
receive $15,000 in commissions, the worth of dollars of machines he must

Therefore,
let
x = amount he will earn
Hence,
15, 000 = 12% of x
15,000 = 12 / 100 × x
15000 = 12x / 100
cross multiply
1500000 = 12x
divide both sides by 12
x = 1,500,000 / 12

1 balls and bins throw n balls into m bins, where m and n are positive integers. Let x be the number of bins with exactly one ball. Compute var(x). Your final answer should not contain any summations
Using 1 balls and bins, n balls are thrown into m bins; m and n are positive numbers. the probability of any given bin containing one ball is n/m n * (1 - (1 - 1/m)^n) / m^2
Given that n is the number of balls and m is the number of bins, the probability of any given bin containing one ball is n/m. Therefore, the variance of x is equal to the variance of a binomial random variable with n trials and probability of success p = n/m.
By the formula for the variance of a binomial random variable, the variance of x is equal to n * (1 - (1 - 1/m)^n) / m^2.

x tickets to have enough money to buy the new dance outfits. Which inequality
represents the situation?
Answer:
x>=45 is the req. inequality
The inequality equation for the number of tickets to be sold is x ≥ 45
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the number of tickets to be sold be x
Let the total amount of money to be saved be = $ 800
The amount of money already saved = $ 350
So , the remaining amount of money = $ 800 - $ 350 = $ 450
The cost of each ticket = $ 10
So , the cost of x tickets = 10x
Now , the number of tickets to be sold to raise $ 450 is given by
10x ≥ 450 be equation (1)
On simplifying the equation , we get
Divide by 10 on both sides of the equation , we get
x ≥ 45
Therefore , the number of tickets to be sold is 45

To find the percent that 1.5 is of 7.5, we need to divide 1.5 by 7.5 and multiply the result by 100% to convert it to a percentage:
1.5 / 7.5 = 0.2
0.2 * 100% = 20%
Therefore, 1.5 is 20% of 7.5.
To find the percent that 5ft is of 37.5ft, we need to divide 5 by 37.5 and multiply the result by 100% to convert it to a percentage:
5ft / 37.5ft = 0.1333
0.1333 * 100% = 13.33%
Therefore, 5ft is 13.33% of 37.5ft.
