Choose all true statements.

Mathematics

AlekseyPX3 years ago

In mathematics, the numbers were classified into different sets that are:

Real Numbers: A set made up of natural, integer, rational, and irrational numbers.

Natural Numbers: A set of numbers that are used to count, is denoted by N, and is N = {1,2,3,4,5, ...}. For every natural number n, there is its next one represented by n + 1.

Whole Numbers: A set made up of natural numbers, their opposites (negative), and zero.

Rational Numbers: A set made up of all the quotients of two whole numbers where the denominator is different from zero

Irrational Numbers: A set made up of all infinite non-periodic decimal numbers.

Based on the above definitions, it can be inferred that the true statements are:

  • Some rational numbers are natural numbers
  • All integers are integers
  • Some integers are natural numbers

Which of the following describes the behavior of the graph shown over the interval (-2,2)?
sergejj [24]

Hello!

We are trying to describe the behavior of the graph given in the question.

To help us understand how to solve this question, we would need to understand <u>concavity.</u>

There are two types of concavity:

  • Concave <em>up</em>
  • Concave <em>down</em>

When a graph is concave up, the slope of the line would look like a "U".

When a graph is concave down, the slope of the line would look like a "U" that is flipped upside down.

In this case, we can see that the graph is concave down.

We can tell that the <em>slope</em> is negative due to the fact that the slope is going <u>down,</u> which results in the graph having a negative slope.

We can also tell that the graph is decreasing due to the fact that the line is doing downward.

Answer:

C). negative and decreasing

Given: EL- tangent, EK- secant <br> Prove: EJ·LK = EL·LJ
drek231 [11]

Answer:

This is possible.

Step-by-step explanation:

We can say that m<E=m<E, because of the Reflexive Property

Then, we have angles JKL and ELJ, which are equal through the peripheral angle theorem.

With these two angles, we can say that triangles ELK and EJL are similar, by the Angle-Angle Postulate (AA).

Then we can create this ratio through the Corresponding Parts of Similar Triangles Theorem, (CPST), \frac{LK}{LJ} =\frac{EL}{EJ}.

With this ratio, we can cross multiply to get the desired result

EJ·LK=EL·LJ

Hope this helps with your RSM problem

Yup, i caught ya.

Inferential statistical tests are used for all of the following except: a. describing a sample with means and standard deviation
Anika [276]

Answer:

a. Describing a sample with mean and standard deviation.

Step-by-step explanation:

Statistics can be categorized into descriptive and inferential statistics.

descriptive statistics uses data for descriptions through numerical analysis. It can be further divided in four parts.

  • Measures of Central Tendency ( Mean, Median, and Mode)
  • Measures of Frequency (Count, Percent, Frequency)
  • Measures of Position (Percentile Ranks, Quartile Ranks.)
  • Measures of Dispersion ( Range, Standard Deviation)

Inferential statistics however is based on assumptions and conclusions and generalizations drawn from samples or checks.

options b to d are all examples of inferential statistics while option a is an example of descriptive statistics.

Answerrr? Please I need help
nadezda [96]

Answer:

21

Step-by-step explanation:

f^{3} + 11g - 4h

f = 3, g = 2 and h = 7.

Substitute the above values into the expression.

3^{3} + 11 × 2 - 4 × 7

Since there's no addition, subtraction or division signs between 11g and 4h, this basically shows that it is multiplied. Simplify further...

3^{3} is 3×3×3 which equals to 27

11 × 2 equals to 22, and

-4 × 7 = -28

Put all these found values into an expression.

27 + 22 - 28

Use the B.O.D.M.A.S. rule. First we have to add then subtract.

(27 + 22) - 28

49 - 28 = 21
