The sequence or pattern [[tex]x_{n}[/tex]] [tex]x_{n}[/tex] Converges to Zero, meaning that the power, limit, and final solution all get closer to zero.
What do you mean by mathematical sequence?A grouping of numbers in a specific order is known as a sequence. On the other hand, a series is described as the accumulation of a sequence's constituent parts. The length of the series is the number of elements (potentially infinite).Unlike a set, a sequence may contain the same things more than once at different locations, and unlike a set, the sequence's order is crucial.
According to given information;

There are some common methods of data collection in statistical studies which are sample survey, observational study, experiments e.t.c
A sample survey is a survey that is done by taking a sample of people or items that represent a larger population.
An observational study is a type of study whereby a researcher utilizes observed information to gain more information about a group of individuals.
An experiment is where a researcher purposely applies different treatments to different groups and then does a comparison of the groups to determine if there is any difference in a specific variable of interest.

Step-by-step explanation:
Six friends each use $2-off coupons to but themselves a movie ticket. They spend a total of $42. What is the price of one movie ticket without coupon?
Modelling the situation, it is found the price of the ticket without the coupon is of $9 when all the six friends spent $ 42 to buy the tickets.
Total money spent by 6 friends on purchasing of the movie tickets = $ 42
So, the money spent for the purchase of 1 ticket will be calculated by dividing the $ 42 by 6.
So, cost of 1 ticket = 4 42 / 6 = $ 7
Coupon is of $2-off.
This means that with the coupon, $2 is subtracted from the ticket price.
So, price of ticket will be = $ 7 + $ 2 = $ 9.
Therefore, the price of the ticket without the coupons will be $ 9.

The set of ordered pairs that represents a function is the third option.
{ (4, 1), (-6, 6), (5, -2), (-4, 1)}
Which set of ordered pairs represents a function?
For a relation that maps elements x (inputs) into elements y (outputs), we will have ordered pairs of the form (x, y) that define the relation.
Now, a relation is only a function if input are only mapped to only one output.
For example, if you look at the first set of ordered pairs, you can see that the input x = -4 appears twice with two different outputs, then this relation does not represent a function.
For the second set the same thing happens for the input x = -8, and for the last set the same happens for the input x = -8
The only set where each input appears only once is the third one:
{ (4, 1), (-6, 6), (5, -2), (-4, 1)}

There are 35 students in a class. Fifteen of them are men and 20 of them are women. The mean height of the men is 69.65 inches, and the mean height of all 35 students is 66.85 inches. What is the mean height of the women?
Answer:
64.75
Step-by-step explanation:
The total heights of men is m
so m/15 = 69.65 => m = 1044.75
The total heights of all students is s
so s/35 = 66.85 => s = 2339.75
so the total heights of women = 2339.75 - 1044.75 = 1295
The mean height of women = 1295/20 = 64.75

A line passes through the point (-2, 6) and has a slope of -8.
Write an equation in slope-intercept form for this line.
The given equation of the straight line is y +8x+10=0
We are required to find the equation of a straight line passing through the point (-2, 6) and has a slope of -8.
An equation of a straight line can be easily found if the slope and any of the points is given
The general form of equation is given by
y-y1 = m (x-x1)
where x1,y1 is the coordinate of the known point
m is the slope of the line
It is given that the coordinate of the known point is (-2,6)
the slope is given to be -8
Thus using these values to form the equation,
y-6 = -8 (x--2)
y-6 = -8 (x+2)
y-6 = -8x-16
y+8x-6+16=0
y+8x+`10=0

Step-by-step explanation:
Draw LMN with vertices L(2,-2), M(7,-3), and N(5,2). Find the coordinates of the vertices after a 90 degree rotation about the origin and about each of the points L, M, and N.
The rotation of the vertices L(2,-2), M(7,-3), and N(5,2) are L'(-2, -2), M'(-7, -3), and N'(5, 2) respectively.
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
We know that the rotation of a point (x,y) about the origin by 90° is (-y,x).
Given vertices of ΔLMN are L(2,-2), M(7,-3), and N(5,2).
Let consider the rotations of L, M, and N are L', M', and N' respectively.
The rotation of a point L(2,-2) about the origin by 90° is L'(-2,-2).
The rotation of a point M(7,-3) about the origin by 90° is M'(-7,-3).
The rotation of a point N(5,2) about the origin by 90° is N'(5,2).
Hence, the points L'(-2, -2), M'(-7, -3), and N'(5, 2) are the rotation of vertices.
Therefore, L, M, and N of ΔLMN about the origin by 90°.
Hence, The rotation of the vertices L(2,-2), M(7,-3), and N(5,2) are L'(-2, -2), M'(-7, -3), and N'(5, 2) respectively.

The days it would take to complete the building is 104 22/25 days.
How many days would it take to complete the building?A fraction is a non-integer that has a numerator and a denominator. The numerator is the number above. While the denominator is the number below. An example of a fraction is 1/4.
A mixed number is a number that has a whole number and a proper fraction. A proper fraction is a non-integer in which the numerator is less than the denominator. An example of a mixed number is 3 1/2.
The first step is to determine the total height of the office bulding = height of each floor x total number of floors
15 x 10 2/5
15 x 52/5 = 780 /5 = 156
The next step is to determine the floors left to complete the office building :
156 - 24 9/10 = 131 1/10 feet
The last step is to divide the feet that can be built each day by the number of floors needed to complete the builfing :

Tony's Used Car Dealership is selling a car for $12,000. This price represents a 20%
reduction from the original price of the car. What was the original price of the car?
The original price of the car is $15,000
Let us assume the original price of car be x. So, forming the equation to find the value of x and hence the original price of the car.
Equation -
x - 20% × x = 12000
x - 20/100×x = 12000
Cancelling zero as common in both numerator and denominator, on the left hand side of the equation
x - x/5 = 12000
Taking LCM on Left Hand Side of the equation
(5x - x)/5 = 12000
Rewriting the equation
4x = 12000 × 5
Performing multiplication on Right Hand Side of the equation
4x = 60,000
x = 60,000 ÷ 4
Performing division
x = 15,000
Therefore, the original price of the car is $15,000.
