No, not all isosceles triangles are always similar. Two triangles are considered similar if their corresponding angles are congruent and their corresponding sides are in proportion. While all equilateral triangles are also isosceles triangles, not all isosceles triangles have congruent angles and proportional sides.
Any triangle with any two sides that have the same length is known as an isosceles triangle. An isosceles triangle has two equal-sized angles that are opposite from one other and have equal sides. Triangles are three-sided polygons in geometry that can be divided into three groups based on their sides, such as:
Scalene triangle (All three sides are unequal)Isosceles triangle (Only two sides are equal)Equilateral triangle (All three sides are equal)For example, consider an isosceles triangle with base angles of 70 degrees and a third angle of 40 degrees, and another isosceles triangle with base angles of 80 degrees and a third angle of 20 degrees. These triangles have different angles and are therefore not similar, even though they are both isosceles triangles.

a statistical technique that would allow a researcher to cluster such traits as being talkative, social, and adventurous with extroversion is called:________
Cluster Analysis is a statistical technique that is used to group a set of objects into clusters such that objects within the same cluster are similar to one another and objects in different clusters are dissimilar. This technique can be used to group traits such as being talkative, social, and adventurous with extroversion.
The cluster analysis is performed by assigning each trait to a group, or cluster, based on the similarity of the traits. For example, if two traits are very similar, they may be grouped together. The cluster analysis uses various algorithms to determine which traits should be grouped together. These algorithms can be based on Euclidean distance, correlation, or other measures of similarity. Once the clusters have been created, the researcher can then analyze the clusters to see how they are related to extroversion. For example, the researcher may find that traits such as talkativeness and socialness are strongly correlated with extroversion, while adventurousness is only weakly correlated. This allows the researcher to identify which traits are most strongly associated with extroversion.
Overall, Cluster Analysis is a powerful statistical technique that can be used to group traits such as being talkative, social, and adventurous with extroversion. This technique can help researchers understand the relationship between various traits and extroversion and can be used to develop better intervention strategies for individuals who exhibit certain personality traits.

4 The 2018 population of Chicago, Illinois, was 2,720,546 people. The 2018
population of Austin, Texas, was about 900,000 people. How many times
greater was the population of Chicago than Austin? Show your work.
Answer:
3 times greater
Step-by-step explanation:
To find out how many times greater the population of Chicago is than Austin, we can divide the population of Chicago by the population of Austin:
Population of Chicago / Population of Austin = 2,720,546 / 900,000
Simplifying the expression by dividing both the numerator and denominator by 100,000, we get:
Population of Chicago / Population of Austin = 27.20546 / 9
Dividing these numbers, we get:
Population of Chicago / Population of Austin = 3.022838
Therefore, the population of Chicago is about 3 times greater than the population of Austin.

The number [square] can divided exactly by six. and when [square] is divided by five, four is the number left over is:
12, 42, 72 o 102
Which of these could [square] stand for?The number [square] can be represented as 6x, where x is any positive integer, since it can be divided exactly by six. When [square] is divided by five, four is the number left over. Therefore, we can write the equation:
6x = 5y + 4
Where y is any positive integer. We can rearrange the equation to solve for x:
6x - 4 = 5y
2x - 2 = (5/3)y
2x - 2 = (5/3)(3x/5)
2x - 2 = (15/15)x
2x - 2 = x
x = 2
Therefore, the smallest possible value for [square] is 6(2) = 12. The next smallest possible value for [square] would be 6(2 + 5) = 42, since adding multiples of 5 to x will still satisfy the equation. The possible values for [square] are 12, 42, 72, 102, etc.

The radius of a circle is 6 inches. What is the area of a sector bounded by a central angle measuring 120°
Knowing that a circle has a radius of 6 inches, the area of a sector with a central angle of 120º is 12π square inches.
The area of a sector can be found using the formula:
Area of sector = (Central angle/360°) × π × r²
Where "central angle" is the angle of the sector in degrees and "r" is the radius of the circle.
In this case, the central angle is 120° and the radius is 6 inches. Plugging these values into the formula, we get:
Area of sector = (120°/360°) × π × 6²
Area of sector = (1/3) × π × 36
Area of sector = 12π square inches
Therefore, the area of the sector bounded by a central angle measuring 120° in a circle with a radius of 6 inches is 12π square inches.

describe the operations you can use to solve the equation x^2 + 5= 86. Then determine the solution.
Answer:
see explanation
Step-by-step explanation:
One method of solution is given below
x² + 5 = 86 ( subtract 5 from both sides )
x² = 81 ( take the square root of both sides )
x = ± [tex]\sqrt{81}[/tex] = ± 9
To solve the equation x^2 + 5 = 86, we need to isolate the variable x on one side of the equation. We can do this by performing the opposite operations on each side of the equation.
Subtract 5 from both sides of the equation:
x^2 = 81
Take the square root of both sides of the equation:
x = ±9
Therefore, the solutions to the equation x^2 + 5 = 86 are x = 9 and x = -9.
