Answer:
There are few kind of statistics: first of all - Mathematiсal statistics. This is quite a mathematical science.
Its applications widely used in many branches of science. First of all (for me) in measurement theory. When used correctly, there is no objection to this science and its methods.
The use in the so-called "social sciences", primarily in sociology, raises many questions: first and foremost - how representative is the "sample"? To what extent does the question asked by the respondent dictate the “correct” (expected) answer? And so on. Of course, this is not a statistic, but mostly a science-like hype, covering up the absence of objective methods.

Answer:
2 hours
Step-by-step explanation:
Train B's speed: 4/3 × 60 = 80
Combined speed = 80 + 60 = 120
Time = 240/120 = 2
Answer:
The measure of angle k In the original triangle and the measure of the corresponding angle k' in the transformed triangle would be equal
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. If a shape is transformed, then all its points are also transformed. Types of transformation are rotation, reflection, translation and dilation.
Rigid transformations are transformations that preserves both length and angle, examples are translation, rotation and reflection. Dilation does not preserve length, hence it is not a rigid transformation.
The measure of angle k In the original triangle and the measure of the corresponding angle k' in the transformed triangle would be the same because reflection and rotation are rigid transformation that preserves length and angle of a shape
Answer:
Step-by-step explanation:
Answer:
First number = 22
Second number = 24
Step-by-step explanation:
Let the first number = x
Let the second number = x + 2
According to the question ,
The sum of two even consecutive ingers = 46.
so,
x + x + 2 = 46
2x + 2 = 46
2x = 46 - 2
2x = 44
x = 44 / 2
x = 22
∴ FIRST NUMBER = X
= 22
SECOND NUMBER = X + 2
= 22 + 2
= 24.
