The 46th term of a Arithmetic Progression (AP) is (a₄₆ = 95.)
What is the AP arithmetic progression sequence?The difference between the two numerical orders is a constant value in Arithmetic Progression (AP). Another name for it is Arithmetic Sequence.
We'd end up coming across a few key words in AP, which were denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)The AP can also be defined in terms of common differences, as shown below.
The method for calculating an AP's n-th term is as follows: an = a + (n − 1) × dThe following is the arithmetic progression sum: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, in the question, the given sequence is; 3,5,7, ...........
Assume the first term is'a₁' = 3
Assume 'a₂' = 5 is the second term.
Assume the third term is 'a₃' = 7
Find the common difference;
d = a₂ - a₁
Substitute the values in the above equation;
d = 5 - 3 = 2
Now, to calculate the value of the 46th term use the formula of nth term.
an = a + (n − 1) × d , n = total number of terms = 46.
Substitute all the values;
a₄₆ = 5 + (46 - 1) × 2
a₄₆ = 5 + 45 × 2
a₄₆ = 5 + 90
a₄₆ = 95
Therefore, the value of the 46th term is estimated as 95.

What is a triangle ?
A triangle is a 3-sided shape. There are three sides and three angles in every triangle, some of which may be the same.
As per the question ;
The West Texas Triangle is an isosceles triangle.
1st location has coordinates (31.9°N , 102.3°W)
2nd location has coordinates (32.7°N , 99.3°W)
3rd location has coordinates (31.4°N , 100.5°W)
Let's represent 1st location as A , 2nd location as B and 3rd as C.
Let's check it.
Using the distance formula ;
AB = √ [ (32.7 - 31.9) ² + (102.3 - 99.3)²]
AB = √ (0.8² + 3²)
AB = √9.64
AB = 3.10
Similarly ;
BC = √ (1.3² + 1.2²)
BC = √3.13
BC = 1.8
And
AC = √(0.5² + 1.8²)
AC = 1.8
The two sides are of equal length , so , we can conclude that this is an isosceles triangle.
Thus , the West Texas Triangle formed is an isosceles triangle.

The 32th term of the arithmetic sequence AP is found to be -146.
What is the definition of arithmetic progression?An arithmetic progression (AP) is a succession in which each successive term has the same distinctions.
Each term in an arithmetic progression (except the first) is derived by adding a certain number to a term before the first one.The following arithmetic progression formulas are frequently used to solve various AP problems for the initial term 'a' of an AP along with the common difference 'd.'The common difference of AP is 'd': d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1. nth term of an AP: an = a + (n - 1) dThe sum of an AP's n terms is Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the final term of the AP.Now, to answer the question;
The given sequence of the numbers is-
9,4,-1,-6,-11, ...........
There are total 32 terms in the series for which we have to find 32nd number.
Let the first term be 'a₁' = 9.
Let the second term be 'a₂' = 4
Let the third term be 'a₃' = -1.
The common difference of between the two consecutive terms is equal of an AP is 'd'.
d = a₂ - a₁
Substitute the values in the above equation;
d = 4 - 9
d = -5
Now, the 32th term is calculated by the nth term formula;
nth term of an AP: an = a + (n - 1) dWhere, total number of terms is; n = 32First term is a = 9common difference d = -5Now, substitute all the value in the formula,
a₃₂ = a + (n - 1) d
a₃₂ = 9 + (32 - 1)(-5)
a₃₂ = 9 - 160 + 5
a₃₂ = -146.
Therefore, the 32nd term of the arithmetic sequence is estimated as -146.

Tetsuya and Mason want to determine the probability that a red marble will be chosen out of a bag of 4 red, 7 blue, 5 green, and 2 purple marbles. Is either of them correct? Explain your reasoning.
Both Tetsuya and Mason are interested in finding the probability that a red marble will be chosen out of the bag. We will decide if either of them is correct.
In statistics, what does a probability mean?
The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is. P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.Tetsuya P( R) = 4/17
Mason P( R ) = 1 - 4/18
P ( R) = Favorable outcome/ possible outcome
The number of favorable outcomes is the number of red marbles in the bag, so it is equal to 4. The number of possible outcomes is the number of all marbles in the bag. Let's find it.
4 + 7 + 5 + 2 = 18
We have enough information to find the probability that a red marble will be chosen P(R).
P( R) = 4/18
Tetsuya used the wrong number of possible outcomes in the denominator. Let's look at Mason's solution. They wanted to use the probability of complementary events. However, they found the probability that a selected marble is not red.

Before it was demolished, the RCA Dome was home to the Indianapolis Colts. The attendance in 2001 was 450,746, and the attendance in 2005 was 457,373 .
b. If this rate of change continues, predict the attendance for 2012 .
If this rate of change continues, the attendance for the year 2012 will be 468973.
Slope(m) for given two points (x₁,y₁) and (x₂,y₂) is calculated using the formula
m=(y₂-y₁)/(x₂-x₁)
in the given question ,we will take year as x coordinate and the attendance as y coordinate.
Given " The attendance in 2001 was 450,746" , So
The point becomes (2001,450746)
and "the attendance in 2005 was 457,373" So
the point becomes (2005,457373)
Now as we have the two points , slope can be calculated as
m=(457373-450746)/(2005-2001)
m=6627/4
m≅1657
Hence the rate of change is 1657 persons per year
It is given in the question that rate of change remains constant.
To predict the attendance for the year 2012.
Let the attendance for the year 2012 be x.
we have (2001,450746) and (2012,x)
let m=1657, x₁=2001 , y₁=450746 , x₂=2012 , y₂=x

Function f. graphed below, is NOT an invertible function.
To which intervals could we restrict the domain off to make it an invertible function?
Choose all answers that apply:
the function f(x) is invertible on the intervals:
B: -7 ≤ x ≤ -4
C : 1 ≤ x ≤ 3
In which intervals is the function invertible?A function f(x) can only be invertible if it is one-to-one in its domain, where one-to-one means that each output is related to only one input.
So, if for two different values x₁ and x₂ we have that:
f(x₁) = f(x₂) = y, then the function is not invertible.
So here what we need to do is identify in which interval is the function one-to-one.
If you look at the last option, we have the interval [1, 3]
We have that f(1) = 2, and then the function increases until f(3) = 4
In that interval the function is cleraly one-to-one, so, on that interval, we can find an inverse function to f(x).
Similarly, on the second option [-7, -4] we also can see that:
f(-7) = 2
And then the function increases until f(-4) = 4
Then the function is also invertible on that interval.
We conclude that the function f(x) is invertible on the intervals:
B: -7 ≤ x ≤ -4

Finding the initial amount and rate of change given a table for a linear function
The initial amount and rate of change given a table for a linear function are $65 and $86, respectively
How to find the initial amount and rate of change given a table for a linear function?The table of linear function represents the given parameter
On the table, we have the following points
(x, y) = (6, 476) and (10, 736)
The rate of change is calculated as
Rate = (y2 - y1)/(x2 - x1)
So, we have
Rate = (736 - 476)/(10 - 6)
Evaluate
Rate = 65
This means that the rate of change is $65
The initial amount is calculated as
y = m(x - x1) + y1
Where
m = 65
So, we have
y = 65(x - x1) + y1
Using one of the points, we have
y = 65(x - 6) + 476
Set x = 0
So, we have
y = 65(0 - 6) + 476
Evaluate
y = 86
Hence, the initial amount and rate of change given a table for a linear function are $65 and $86, respectively
