0.123 < 2 > 0.1002, is the true statement after inserting symbols.
What is greater than symbol refer?
In mathematics, the larger than sign is used between two numbers to indicate that the first number is greater than the second. For instance, 10 > 5. 10 is more than 5 in this case.The greater than symbol, which consists of two strokes of equal length joined at an acute angle at the right, is always pointed toward the greater value in inequality. ( >).What is lesser than symbol refer?
In a situation when one number is less than another, a less than symbol is positioned between the two numbersWhen referring to an inequality, the less than symbol () represents the smaller value where two strokes of equal length meet at a sharp angle on the left.The reader may easily understand the message thanks to the larger than less than sign, which also decreases the time complexity.What is equal to symbol refer?
The "equal to" symbol is used to indicate that two numbers or values are equal. The greater than and less than signs are in conflict with this one. We employ the equal to symbol even while writing equations. '=' is used to indicate it.Hence, 0.123 < 2 > 0.1002, is the true statement after inserting symbols.

The analysis of the tables based on the first difference values indicates
1 a. The function is a linear function
b The reason the function is linear is because the rate of change in the x and y-values are constant, such that the rate of change of the function is also constant
2. a. The function is not linear
b. This is so because the changes in the consecutive terms of the x-values is not constant while the change in the y-values is constant making the overall rate of change of the function (the slope of the function) to vary
3. a. The table is not a linear function
b. The reason why the table does not represent a linear function is because the change in the terms of the y-values is not constant
4. a. The table is a linear function
b. The reason why it is a linear function is because the changes in the x and y-values are constant
What is a linear function?A linear function is a function that when plotted on a graph, forms a straight line.
1) The changes in x-values are;
Δx₁ = -2 - (-3) = 1
Δx₂ = -1 - (-2) = 1
Δx₃ = 0 - (-1) = 1
Δx₄ = 1 - 0 = 1
The changes in y-values are;
Δy₁ = 2 - 1 = 1
Δy₂ = 3 - 2 = 1
Δy₃ = 4 - 3 = 1
Δy₄ = 5 - 4 = 1
a. Is it a linear function? Yes
b. Why it is a linear function is because the first difference of the y-values and the change between consecutive x-values are both constant
2. The changes in x-values are;
Δx₁ = -2 - (-5) = 3
Δx₂ = -1 - (-2) = 1
Δx₃ = 2 - (-1) = 3
Δx₄ = 5 - 2 = 3
The changes in y-values are;
Δy₁ = 4 - 2 = 2
Δy₂ = 6 - 4 = 2
Δy₃ = 8 - 6 = 2
Δy₄ = 10 - 8 = 2
a. Is it a linear function? No
b. The reason why it is not a linear function is because the rate of change in the y-values is constant while the rate of change in the x-values varies, which indicates that the rate of the function also varies resulting in a non linear function.
3. The changes in x-values are;
Δx₁ = -5 - (-10) = 5
Δx₂ = 0 - (-5) = 5
Δx₃ = 5 - 0 = 5
Δx₄ = 10 - 5 = 5
The changes in y-values are;
Δy₁ = 4 - 9 = -5
Δy₂ = 2 - 4 = -2
Δy₃ = 0 - 2 = -2
Δy₄ = -3 - 0 = 2
a. Is it a linear function? No
b. The reason why the table of values does not represent the values of a linear function is that the first difference, which is the change in the consecutive y-values is not constant, such that the rate of changes of the ordered pairs of the function function is not constant and the graph therefore does not follow a straight line pattern
4) The changes in x-values are;
Δx₁ = 3 - (-1) = 4
Δx₂ = 7 - 3 = 4
Δx₃ = 11 - 7 = 4
Δx₄ = 15 - 11 = 4
The changes in y-values are;
Δy₁ = -4 - (-9) = 5
Δy₂ = 1 - (-4) = 5
Δy₃ = 6 - 1 = 5
Δy₄ = 11 - 6 = 5
a. Is it a function? yes

In a set of eight consecutive integers, the smallest integer is more than $\frac35$ of the largest integer. What is the smallest possible value of the sum of the eight integers?
The smallest possible value of the sum of the eight integers is given by:
116.
What are the integers?The eight integers in the problem are given as follows:
n, ..., n + 7.
Hence:
The smallest integer is of n.The largest integer is of n + 7.The smallest integer is more than 3/5 of the largest integer, hence the following inequality is built to relate them:
n > 3/5(n + 7)
Applying the distributive property on the right side, we have that:
n > 0.6n + 4.2.
0.4n > 4.2
n > 4.2/0.4
n > 10.5.
Hence the integers are:
11, 12, 13, 14, 15, 16, 17, 18.
(as 11 is the smallest integer possible).
Then the value of the sum is obtained as follows:
11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 = 116.

Find x, y and z. I really need help!
Answer:
x = 74°y = 37°z = 25°Step-by-step explanation:
x° and 106° are same side interior angles, meaning they're supplementary and adds up to 180°. Therefore, you can find the value of x by:
[tex]x+106=180\\\\x=180-106=74[/tex]
x° and 2y° are corresponding angles, meaning they're equal. Therefore, you can find the value of y by:

1. the best point estimate for the population mean is the sample mean. 2. as the length of a confidence interval increases, the degree of confidence in its actually containing the population parameter being estimated (confidence level) also increases. 3. if the length of a confidence interval is very large, then the corresponding prediction is very meaningful. 4. a 90% confidence interval for a population mean implies that there is a 0.90 probability that the true population mean will be contained in the confidence interval. 5. a 90% confidence interval for a population parameter means that if a large number of confidence intervals were constructed from repeated samples, then on average, 90% of these intervals would contain the true parameter. 6. the point estimate of a population parameter is always at the center of the confidence interval for the parameter. 7. when repeated samples are selected from a population, the point estimate for a given parameter will always be the same value. 8. the larger the level of confidence, the shorter the confidence interval.
The solutions for all the given statements are,
1. True, 2. True, 3. False, 4. True, 5. True, 6. True, 7. False, 8. False
Given statements and their conclusions;
1. The best point estimate for the population mean is the sample mean.
→ True, since the central limit theorem states that the sample mean corresponds to the population mean.
2. The level of confidence that a confidence interval contains the population parameter being estimated increases as its length does (confidence level).
→ True, when the CI widens, our confidence grows as well since we are more certain that the true mean (or another statistic) will fall inside the range.
3. If a confidence interval is very long, it means that the corresponding prediction is highly significant.
→ False, as the length increases, the confidence interval's range similarly expands, giving the correct point estimate a wider range of possible values.
4. A 90% confidence interval for a population mean implies that there is a 0.90 probability that the true population means will be contained in the confidence interval.
→ True, a 90% CI means that we are 90% confident that the range of the confidence interval contains the true value of the mean.
5. A 90% confidence interval for a population parameter means that if a large number of confidence intervals were constructed from repeated samples, then on average, 90% of these intervals would contain the true parameter.
→ True, 90% of the values attains positive values.
6.A population parameter's point estimate is always in the middle of the parameter's confidence interval.
→ It is true that the sample statistic, such as a sample mean or sample proportion, is at the center of a confidence interval. The point estimate is what is used here. The margin of error determines the width of the confidence interval.
7. A population's point estimate for a particular parameter will always be the same when repeated samples are taken from it.
→ False.
8. The larger the level of confidence, the shorter the confidence interval.
→ False, an increase in the margin of error follows an increase in the level of confidence. A broader confidence interval is produced by a higher margin of error.

Subtraction serves as a representation for the act of removing items from a collection. The negative symbol stands for subtraction. For example, if four of the nine oranges that are stacked together (as in the above illustration) are then transported to a basket, the stack will now contain five oranges rather than nine. Therefore, the difference between 9 and 4 is 5, which equals 9 minus 4. In addition to applying it to natural numbers, subtraction can also be used with other kinds of numbers. The letter "-" represents subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation.

Find the sum if it exists of the infinite geometric series related to the infinite geometric sequence described by an=12(0.2)^n-1
The sum of the infinite geometric sequence exists and is equal to 15.
We are given an expression for terms in a geometric progression. The term at position "n" is given by the following formula.
T(n) = 12(0.2)^(n - 1)
The general representation for the terms in a geometric sequence is given by : T(n) = a*r^(n - 1).
Here, the variables "a" and "r" represent the first term and the common ratio for the geometric progression. On comparing the given formula with the standard representation, we conclude that the first term of the given geometric progression is 12 and the common ratio is 0.2.
a = 12
r = 0.2
The sum of an infinite geometric sequence exists if the common ratio lies between -1 and 1.
-1 < r < 1
-1 < 0.2 < 1
The above inequality holds true, so the sum exists. Let the sum of the infinite geometric sequence be denoted by "S". The formula and calculations are below.
S = a/(1 - r)
S = 12(1 - 0.2)
S = 12/0.8

8. Aleks is writing a report about recycling in the local town. In 2021: There were 2341 people living in the town Each person in the town recycled an average of 264.6kg of waste. Aleks knows that 1tonne = 1000kg. How many tonnes of waste were recycled in town in total in 2022?
The tons of waste recycled in 2021 was 619.4286 tons.
According to the question,
We have the following information:
In 2021: There were 2341 people living in the town. Each person in the town recycled an average of 264.6kg of waste. Aleks knows that 1 ton = 1000kg.
Now, the total waste recycled in 2021 can be found using multiplication:
Number of people*waste recycled by each person
2341*264.6
619428.6 kg
Now, we will convert this from kilogram to tons.
1 ton = 1000 kg
1 kg = 1/1000 ton
So, we will divide the waste in kilogram by 1000:
Total waste recycled = 619428.6/1000
Total waste recycled = 619.4286 tons
Hence, the tons of waste recycled in 2021 was 619.4286 tons.
