Step-by-step explanation:

1882 - 9937

the easiest way to do it is to turn it around :

9937 - 1882

= 8055

then you add a subtraction sign at the back

= - 8055

What is x in the similar triangles? Please help:)

topjm [15]

Answer:

x = 18

Step-by-step explanation:

Since both right triangles are similar, therefore:

$\frac{2x - 6}{20} = \frac{39}{x + 8}$

Cross multiply

$(2x - 6)(x + 8) = 39*20$

$2x(x + 8) -6(x + 8) = 780$

$2x^2 + 16x - 6x - 48 = 780$

$2x^2 + 10x - 48 = 780$

Subtract 780 from both sides

$2x^2 + 10x - 48 - 780 = 0$

$2x^2 + 10x - 828 = 0$

$2x^2 + 46x - 36x - 828 = 0$

$2x(x + 23) - 36(x + 23) = 0$

$(x + 23)(2x - 36) = 0$

x + 23 = 0

x = -23

2x - 36 = 0

2x = 36

x = 18

The collection of all possible outcomes of a random phenomenon is called A. the sample space. B. the distribution. C. the probab

Hoochie [10]

Answer:

Option A is correct.

Sample space is the collection of all possible outcomes of a random phenomenon.

Step-by-step explanation:

- Sample Space

The sample space of a phenomenon is the set of all possible outcomes for that phenomenon.

- Distribution

The distribution of a statistical data set is defined as a listing or function showing all the possible values (or intervals) of the data and how often they occur.

- Probability

Probability describes how likely something is to happen. Probability values are usually between 0 and 1; with 0 denoting impossibility and 1 denoting total certainty.

- Census

Census is an official count or survey of a population

The type of polynomial that would best model the data is a cubic polynomial. (Correct choice: D)

<h3>What kind of polynomial does fit best to a set of points?</h3>

In this question we must find a kind of polynomial whose form offers the best approximation to the point set, that is, the least polynomial whose mean square error is reasonable.

In a graphing tool we notice that the least polynomial must be a cubic polynomial, as there is no enough symmetry between (10, 9.37) and (14, 8.79), and the points (6, 3.88), (8, 6.48) and (10, 9.37) exhibits a pseudo-linear behavior.
