Answer: The equation of the perpendicular bisector of AB is 3x+7y-77=0
A line equation is an algebraic representation of a set of points that together form a line in a coordinate system. Multiple points that together form a line on the coordinate axis are represented as a set of x,y variables to form an algebraic equation called a one-line equation.
Equation of line⇒[tex](y-y1)=\frac{(y2-y1)}{(x2-x1)} (x-x1)[/tex]
Midpoint of line⇒[tex]\frac{(x1+x2)}{2}, \frac{(y1+y2)}{2}[/tex]
Step-by-step explanation:
Line CD⊥AB
Equation of AB⇒ [tex]\frac{y+10}{x-4} =\frac{15-1}{10-4} \\[/tex]
⇒ [tex]\frac{y+10}{x-4} =\frac{14}{6}[/tex]
⇒ [tex]\frac{y+10}{x-4} =\frac{7}{3}[/tex]
⇒ 3(y+10)=7(x-4)
⇒ 3y+30=7x-28
⇒ 7x-3y=30+28
⇒ 7x-3y=58
Midpoint of AB⇒ [tex]\frac{4+10}{2} , \frac{1+15}{2}[/tex]
⇒ [tex]\frac{14}{2}, \frac{16}{2}[/tex]
⇒ (7, 8)
Slope of CD⇒ [tex]\frac{-1}{slope of AB}[/tex]
Slope of AB⇒ [tex]\frac{-7}{-3}[/tex]
⇒ [tex]\frac{7}{3}[/tex]
Slope of CD⇒ [tex]\frac{-3}{7}[/tex]
Equation of CD⇒ [tex]y-8=\frac{-3}{7} (x-7)[/tex]
⇒ 7(y-8)=-3(x-7)
⇒ 7y-56=-3x+21
⇒ 3x+7y-56-21=0
⇒ 3x+7y-77=0

Point z is the circumcenter of δlmn. point z is the circumcenter of triangle l m n. lines are drawn from each point of the triangle to point z. lines are drawn from point z to each side to form right angles and line segments z a, z b, and z c. which must be true?
Answers
The true about all of these statements are:
The lines drawn from each point of the triangle (L, M, N) to point Z will be perpendicular to each side of the triangle. The distance from each vertex of the triangle (L, M, N) to the circumcenter Z will be equal to the distance from the circumcenter to the midpoint of the opposite side of the triangle. The lengths of the segments ZA, ZB, and ZC will be congruent. The segments ZA, ZB, and ZC are the perpendiculars from the circumcenter to each side of the triangle. The circumcenter Z lies on the intersection of the perpendicular bisectors of the sides of the triangle.All three angle bisectors of triangle L,M,N intersect at circumcenter Z.THE CIRCUMCENTER OF TRIANGLEThe lines drawn from each point of the triangle (L, M, N) to point Z will be perpendicular to each side of the triangle. This is because the circumcenter of a triangle is the point that is equidistant from the three vertices of the triangle. When the distance from a point (in this case, the circumcenter Z) to each vertex of the triangle is the same, the line connecting the point to each vertex is perpendicular to the line containing the side opposite the vertex.The distance from each vertex of the triangle (L, M, N) to the circumcenter Z will be equal to the distance from the circumcenter to the midpoint of the opposite side of the triangle. By the definition of circumcenter, the distance from circumcenter to the midpoint of the opposite side is the same as radius of the circumcircle. and it is also the same distance from each vertex of the triangle to the center.The lengths of the segments ZA, ZB, and ZC will be congruent. The segments ZA, ZB, and ZC are the perpendiculars from the circumcenter to each side of the triangle. Since the circumcenter is equidistant from each vertex of the triangle, the lengths of these segments will be the same.The circumcenter Z lies on the intersection of the perpendicular bisectors of the sides of the triangle. The circumcenter is the center of the circumcircle, which is the circle that passes through all three vertices of a triangle. This center is equidistant from the three vertices of the triangle, and it lies on the intersection of the perpendicular bisectors of the sides of the triangle. The perpendicular bisectors are lines that pass through the midpoint of a side of a triangle and are perpendicular to that side. So, the circumcenter is located at the intersection point of the three perpendicular bisectors of a triangle, which is also the point equidistant from all three vertices of the triangle.All three angle bisectors of triangle L,M,N intersect at circumcenter Z.

By applying The Power Rule for Derivatives, it concluded that the value of dQ/dx is 4250[tex]x^{\frac{3}{2} }[/tex]
The Power Rule for Derivatives is a method of differentiation that is used when a mathematical expression with an exponent needs to be differentiated. The rule is:
d(xⁿ) / dx = n(x)ⁿ⁻¹
It is given that the monthly output of a certain product is defined by the function:
Q(x) = 1700[tex]x^{\frac{5}{2} }[/tex]
where x denotes the capital investment in millions of dollars.
Now we want to determine the derivative of the giving function:
d(xⁿ) / dx = n(x)ⁿ⁻¹
dQ / dx = d (1700[tex]x^{\frac{5}{2} }[/tex])

Answers
The line of the equation should be y = 20x + 320 and travelers will spend about $620 billion in the year 2008. So, the option c is correct.
In the given question, we have to write an equation for the line of best fit and then predict how much money travelers will spend in 2008.
The graph of the question is given below:
From the graph the points are (1.5, 350) and (4, 400)
As we know that the formula of the equation of line is:
y-y(1) = {y(2)-y(1)}/{x(2)-x(1)} (x-x(1))
x(1) = 1.5, y(1) = 350, x(2) = 4 and y(2) = 400
Now putting the values
y-350 = (400-350)/(4-1.5) (x-1.5)
y-350 = 50/2.5 (x-1.5)
y-350 = 20(x-1.5)
y-350 = 20x-30
Add 350 on both side, we get
y = 20x + 320
So, the line of the equation should be y = 20x + 320.
So that travelers will spend about $620 billion in the year 2008.
Hence, the option c is correct.

Round your answer to three decimal places if necessary. a. 0.635 c. 0.62 b. 0.629 d. 0.625
Answers
The probability that a resident is female is 0.625.
Probability is a method for determining how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.
We know that the probability of a function is the ratio of favorable cases to the total number of cases possible.
Given that,
Total number of females = 19+2+4 =25
total number of males=1+9+5 = 15
The probability that a resident is female is the Total number of females / total number of people
Hence total number of people = 25+15 = 40
So, Probability = 25/40 = 0.625
Therefore, the probability that a resident is female is 0.625.

Here, sample space i.e., the total number of residents = 40
So, n(S) = 40
Let event A: a resident is female
From the contigency table, the number of favourable outcomes of the event A are 25
So, n(A) = 25
Using the definition of probability, the probability of event A would be,

The resulting coordinate of △ D'E'F' is translated by the vector is (8, 5), (12,3), and (10, 0)
Given the coordinates of vertices of △ DEF as D (2, 5), E (6, 3), and F (4, 0).
If the coordinate of the vertices is translated by the vector (6, 0), the resulting coordinates of △ D'E'F' will be expressed as:
D'= (2+6, 5 + 0) = (8, 5)
E' = (6 + 6, 3 + 0) = (12, 3)
F' = (4 + 6, 0 + 0) = (10, 0)

Step-by-step explanation:
if event a and event b cannot occur at the same time, then events a and b are said to be : (a) mutually exclusive
(b) statistically independent
(c) collectively exhaustive
(d) none of the above
Answers
The correct option is option a) mutually exclusive.
Mutually exclusive events are events that cannot occur simultaneously. They are also referred to as disjoint or incompatible events. In probability theory and statistics, mutually exclusive events have a probability of zero occurring together.
For example, in a coin flip, getting "heads" and getting "tails" are mutually exclusive events because a coin cannot land on both "heads" and "tails" at the same time.
Another example would be the events "rolling a six on a dice" and "rolling an even number on a dice", these events are mutually exclusive because a dice can't land on a six and an even number at the same time.
In general, mutually exclusive events have no intersection, meaning that they don't share any outcomes.
Therefore, The correct option is option a) mutually exclusive.

A juice stand sells two types of fresh juice in 12 oz cups, the Refresher and the Super-Duper. The Refresher is made from 3 oranges, 2 apples and a slice of ginger.
The Super Duper is made from one slice of watermelon, 3 apples and one orange. The owners of the juice stand have 50 oranges, 40 apples, 10 slices of watermelon
and 15 slices of ginger. Let x denote the number of Refreshers they make and let y denote the number of Super-Dupers they make. Which would be correct
constraints for the oranges
Answers
The correct constraints for the oranges would be 3x + y <= 50.
What is the linear equality in two variables?
Linear equality in two variables is an equation that uses a linear function to describe a relationship between two variables (x and y). A linear function is of the form:
ax + by = c
Where a, b, and c are constants, and x and y are the variables.
The correct constraint for the oranges used in the Refresher and Super-Duper juice would be:
3x + y <= 50
This represents the maximum number of oranges that can be used, given the number of Refreshers (x) and Super-Dupers (y) that the juice stand is making. It says that the total number of oranges used in the Refreshers (3 oranges per Refresher) plus the total number of oranges used in the Super-Dupers (1 orange per Super-Duper) must be less than or equal to the total number of oranges the juice stand has on hand (50 oranges).
Hence, the correct constraints for the oranges would be 3x + y <= 50.

The solution for each system of equations is given as follows:
1. x = -4, y = 0.
2. x = 7, y = -2.
How to solve the system of equations?The first system of equations is defined as follows:
2x - y = -8.-3x + 4y = 12.By the substitution method, using the first equation, we have that:
y = 2x + 8.
Replacing in the second, we have that:
-3x + 4(2x + 8) = 12.
-3x + 8x + 32 = 12
5x = -20
x = -20/5
x = -4.
Hence the solution for y is given as follows:
y = 2(-4) + 8 = -8 + 8 = 0.
The second system of equations is defined as follows:
-3x - 6y = -9.-3x - 5y = -11.Multiplying the first equation by -1, we have that:
3x + 6y = 9.-3x - 5y = -11.Adding the two equations, the solution for y is obtained as follows:
y = -2.
Then the solution for x is calculated as follows:
3x + 6(-2) = 9
3x = 21
x = 21/3
x = 7.

Find the values of the variables
Answers
Answer:
W = 59 degree
Y = 59 degree
Z = 53 degree
x = 121 degree
v = 121 degree
Step-by-step explanation:
W = 59 degrees because a triangle has a total of 180 degrees, and we know 2 of the angles, one is 31 degrees and the other is 90 degrees, so
90 + 31 = 121
180 - 121 = 59 degrees
So, W = 59 degrees
Y = 59 degrees because w and y are vertical angles.
z = 53 degrees because
68 + 59 = 127
180 - 127 = 53 degree
So, z = 53 degree
x = 121 degree, y = 121 degree because w, x, y, v add up to 360 degree
59 + 59 = 118
360 - 118 = 242
242 / 2 = 118 degree
So, x and y equal to 118 degrees.
