4 0

Answer:

Step-by-step explanation:

7x + 1 isn't equal to 8x

For example:

Addition. In this equation, you can add all of the coefficients (2, 5, and 4) because the variables are the same (a).

2a + 5a + 4a = 11a

Subtraction. In this equation, you can subtract all of the coefficients (11, 5, and 4) because the variables are the same (a).

11a – 5a – 4a = 2a

A measure of the strength of the relationship between two variables is referred to as the A. standard deviation of the estimate.

marin [14]

Answer:

D. Coefficient of Correlation

Step-by-step explanation:

The name itself "Coefficient of Correlation" involves the word correlation, meaning relationship between two things.

The coefficient of Correlation is used to determine how strong a relationship is between two variables.

The formula of Coefficient of Correlation gives a value between -1 and 1. Moreover, it helps to plot a graph showing the strength of relationship.

1 : A strong positive relationship

-1: A Strong negative relationship

0: No relationship at all

One of the most used formula is Pearson Correlation Coefficient Formula, picture of which is attached. X and Y represent two different set of datas.

Note:

The other terms are defined as :

Coefficient of Determination : Square of correlation between predicted scores and actual scores. It usually ranges from 0 to 1 .

Standard deviation of estimate : represents the amount of variation among a set of values .

Standard Error of estimate : It is the measure of dispersion of sample means around population means.

What is the sign of e + d when e > 0 and d 0?

Artemon [7]

9514 1404 393

Answer:

(B) Negative

Step-by-step explanation:

You can try an example:

c = 1, d = -1

c/d = 1/-1 = -1 . . . . negative

Additional comment

The sign of the result of multiplication and/or division of any number of factors will be negative if there are an odd number of minus signs involved. It will be positive if there are an even number of minus signs involved.

1)Which statement is true about the line passing through points A and B?

Studentka2010 [4]

Part 1:
The statement that is true about the line passing through points A and B is
The line has infinitely many points.

Beacause of the arrows at the endpoints, the line does not have a finite length that can be measured.

Any segment with at least two points has infinitely many points, because, intuitively, given any two distinct points, there is a third one, distinct from both of them, say, the middle point.
Thus, there are not only two points on the entire line.

The line can be called AB or BA, so there is not only one way to name the line.


Part 2:
Line FM can also be named line MF.
Therefore, the correct name for line FM is line MF.
