Thus, 0 itself is the sole position at which [0,∞] and (0,∞] are separated. Since it is in [0,∞] the set is closed. Given that it is not in (0,∞), the set is open interval.
A (real) interval in mathematics is a collection of real numbers that includes all real numbers that fall within any two of the collection's numbers. For instance, the interval containing 0, 1, and all integers in between is the set of values x satisfying 0 x 1. The collection of numbers such that 0 x 1 and the collection of all real numbers are other examples of intervals.
the empty set, any singleton, the set of positive real numbers, the set of nonnegative real numbers, and (set of one element).
Because they are the most basic sets whose "length" (or "measure" or "size") is straightforward to define, real intervals are crucial in the theory of integration. The Borel measure and finally the Lebesgue measure result from extending the notion of measure to more intricate sets of real numbers.
Interval arithmetic is a broad numerical computing technique that automatically generates assured enclosures for arbitrary formulas, even in the presence of uncertainties, mathematical approximations, and arithmetic roundoff. Intervals are at the centre of this technique.
Therefore, 0 itself is the sole place at which [0,∞] and (0,∞] have a boundary. Due to its location in [0,∞] the set is closed. Since it is not in (0,∞), the set is unclosed.

A sample of size 95 will be drawn from a population with mean 25 and standard deviation 13. Find the probability that will be between 22 and 27.
1.3338 is the likelihood, The probability of anything occurring is known as probability.
How are probabilities calculated?The probability of anything occurring is known as probability. To determine probability, divide the total number of possible outcomes by the number of possible ways an event could occur.
The likelihood or chance that a specific event will occur is represented by a probability. Both proportions between 0 and 1 and percentages between 0% and 100% can be used to describe probabilities.
Explanation:
Mean (m) = 25
The standard deviation is 13
Sample size (n) is 95.
Chance that x will fall between 22 and 27.
Zscore = x - mean / s / n
If x = 22, Zscore is equal to (22 - 25) / (13/95).
For x = 27, Zscore is equal to (27 - 25) / (13/95) / n = 13 / 95, which is 1.3338.
1.3338 is the likelihood.

What does FG mean in functions?
FG stands for Function Generator, which is a device that produces electrical signals with a function of frequencies and amplitudes. It is commonly used in scientific laboratories to generate signals for testing and research purposes.
A function generator is an electrical device used to generate electrical signals with a range of frequencies and amplitudes. It is commonly used in scientific laboratories to generate test signals for testing and research purposes. Function generators typically consist of an oscillator, amplifier, and waveform selector. The oscillator generates a signal of a given frequency and amplitude, while the amplifier adjusts the output voltage. The waveform selector allows the user to choose from a variety of waveforms, such as sine, square, triangle, and sawtooth. Function generators can be used to simulate various types of electrical signals, such as AC and DC signals, as well as a variety of noise signals. They are also used to test various types of electronic components, such as transistors and capacitors, and to conduct research in fields such as telecommunications and signal processing.

Step-by-step explanation:

c) The standard deviation is 0.974.
d) The binomial probability is 20.
What is Standard Deviation?A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Given:
n = 20, p = 0.95, q = 1 - 0.95 = 0.05
a) There are only two results per shot and they are independent of each other. Each pitch is independent of the outcome of the other pitches.
b) To calculate the mean of X.

Find the measure of an interior angle of a regular hexagon
Therefore , the solution of the given problem of angles comes out to be
Each inner angle of a regular hexagon measures 120 degrees.
Exactly what angles are there?Two rays that converging at the vertex, or center, of an angular structure in geometry make up the structure. We refer to these rays as the faces of the angle. Two beams may well be able to create any angle within just a planar depending on their location. Additionally, an angle is created when two planes intersect. .
Given: A standard hexagon
Measure each internal angle of a standard hexagon.
Solution:
(n - 2) x 180° is the formula for the sum of lengths of a polygon's inner angles.
Every side of a regular polygon is the same length, and every angle is the same size.
A hexagon has six sides.
Find the total of the measurements of the internal angles of a hexagon by substituting n = 6 in (n - 2) x 180n latitude in step 1.
=> (n - 2) * 180°
=> (6 - 2) * 180°
=>4 * 180°
=> 720°
Step 2: Since a regular hexagon has six sides and all of its sides and angles are equal in size, divide by six to obtain the dimensions of each inner angle.
=> 720° /6
=> 120°
Each internal angle of such a regular polygon is 120 degrees in length.

Probability samples are advantageous to the researcher because: A. they are perfectly representative of the population from which they are drawn. B. the method by which they are selected limits conscious and unconscious sampling bias. C. the method by which they are selected limits conscious and unconscious bias and the accuracy/representativeness of the sample can be estimated. D. they allow the researcher maximum exibility in the creation of samples. E. the accuracy/representativeness of the sample can be estimated.
Answer:
C. the method by which they are selected limits conscious and unconscious bias and the accuracy/representativeness of the sample can be estimated.
Step-by-step explanation:
The probability sampling technique allows for each element in the sample to be representative of the population data from which the samples are drawn. This sort of sampling technique helps to randomize and eliminate errors which might creep into measurement. Since the researcher has the knowledge of the population data or distribution, he takes advantage of these in the allocation of samples using the probabilities of each Sample.

A measurement which could be the side lengths of a right triangle include the following: C. √24 in, √6 in, √30 in.
How to determine the side lengths?In order to determine which measurements could be the side lengths of a right triangle, we would have to apply Pythagorean's theorem.
Mathematically, Pythagorean's theorem is given by this formula:
x² + y² = z²
From the side lengths of the first triangle, we have the following:
(√6)² + (√30)² = (√33)²
6 + 30 = 33
36 = 33 (False).
From the side lengths of the first triangle, we have the following:
(√27)² + (√18)² = (√48)²
27 + 18 = 48
45 = 48 (False).
From the side lengths of the first triangle, we have the following:
(√6)² + (√24)² = (√30)²
6 + 24 = 30
30 = 30 (True).
From the side lengths of the first triangle, we have the following:
(√18)² + (√21)² = (√48)²
18 + 21 = 48

His coordinate grid shows where Alberto's school is located. Each unit represents one block. Alberto's house is at (3, 4). The library is located at the reflection of (3, 4) across the y-axis. Use absolute value to find the distances from Alberto's house to the school and from Alberto's house to the library
The distance from Alberto's house to the school is 4 units and from Alberto's house to the library is 6 units
Consider the following diagram.
From given coordinate grid we can observe that Alberto's school is located at point (-1, 4)
Alberto's house is at (3, 4).
And the library is located at the reflection of (3, 4) across the y-axis.
This means, the libarary is located at point (-3, 4)
We know that the absolute value is nothing but the distance between a number and zero on a number line.
The distance from Alberto's house to the school would be,
= distance between points (3, 4) and (-1, 4)
= |3 - (-1)|
= |3 + 1|
= |4|
= 4 units
And the distance between Alberto's house to the library would be,

Benson is shopping for shampoo. His favorite brand comes in 5 different sizes which size is the best deal
work out the size of angle x
ill mark brainliest first corect answer!
Answer:
65°
Step-by-step explanation:
First we find the sizes of the other two sides, as the bottom line is straight all angles on it must add up to 180 so:
180-105=75
So the first angle is 75°
180-140=40
So the second angle is 40°
Now as the angles of a triangle add up to 180 we can derive this equation:
75+40+x=180
and all we do is just subtract both sides by 75 and 40:
x=180-75-40
x=65
And 65 is our answer
